Hey there Quintin. I see that for number four you answered "Preforming an experiment that has not been done before.", can you elaborate on that? I ask this because there is always the scenario that you're testing the amount of sugar in a drink that has never been tested before, but you could still be using the same kind of "cookbook" we used in class.

1.) From this lab, I learned how to actually double-check on something when I'm looking for information, instead of just pretending I double-checked.
2.) The lab experiment may help me in the future because, now I know how to work with people that may not suit how I work myself. Also, it helped me learn how to make proper measurements, instead of guessing.
3.) I believe it is called "cook-book-like" because the results may not be set, but they're supposed to be close to a set amount.The results are supposed to be as accurate as they can be.
4.) A "non-cook-book-like" experiment could be anything that hasn't been attempted, or you don't know what you're supposed to get/ get close to in results.
5.) I believe some knowledge of the idea I want, maybe even look for what I could try. It wouldn't be exactly set, but it'd be about what I think could work. I'd try to ensure I can actually do the experiment, by that, I mean, one experiment that wouldn't have a possibility to harm anyone in any way. So in short words, a controlled experiment.

I agree with what you said about pretending to double check. I don't double check my homework or test because I feel like if I got it wrong because of my way of thinking going over it again will not fix the problem. This lab is going to make me think twice about not double checking or single checking.

a. What did you learn, or find significant, from this lab experience?
From this lab, I learned how to, one weight something and calculate the different lab "terms" and two how to double check/create a lab.
b. How might this lab experience help you in future learning?
It taught me how to use a scale, THE CORRECT WAY which will serve me a purpose in my career later one (I might want to be a forensic scientist).
c. This type of laboratory work is sometimes referred to as pre-scripted, or cookbook-like. Why do you think it is called this?
I think it is called a "pre-scripted" lab because it has pretty much everything we need to do the expierement. It gives us all the equations and calculations. It has all the instructions and even pictures to help guide you.
d. What type of science work would you describe as not being pre-scripted, or cookbook-like?
I would consider maybe forensic science a non-scripted type of science because usually you have to figure things out on your own. I mean,you have the equations you could possibly use, but you have to really do a lot of thinking. Whereas in the lab expierement you gave us, we didnt really have to do much thinking, we just had to use calculators.
e. Later in our course, you will get the opportunity to design your own experiment. What do you think will be necessary to do this?
I think to create or design our own expierements we would need a subject. Or we would need a handout on what we should take away from it, the basic kind of general idea. I would think a little direction would be needed because we arent very expierenced in science at High Tech High yet.

I agree with you on how would you consider a non pre-scripted lab or science work because we really didn't do much thinking and actually using our minds to connect things which can help you find the solution.
Also vise versa on how pre-scripted work is everything from equations and stuff is given to you and how we just have to use calculators and that's it.

1. From this lab I learned to weight properly and find out the percentage of sugar that drinks have, and how much we can consume without knowing.

2. It helped me know who can be a good partner to work with when it comes to labs.

3. It can really help you on bgetting good and accurate measures for labs in the future because sometimes my group wasn't as precise we would of want to because we didn't filter it right into the flask.

4. I believe it's better when people work as a team in this case Ididn't as much because my group got out of task.

In your last response, I'm not quite sure if you answered the question. I believe Andrew meant, what is necessary to "design" an experiment. As much as your statement is true, What do you believe needs to be done to successfully create an experiment?

Grace Ojeda

1)I found that I actually enjoy doing labs. In the past I didn’t really understand them as far as measurements and figuring out the equations. Going in I felt like I had a good understanding of what we were going to be doing and what we needed from the lab. I also chose people who I knew I could work with.
2)If the future I know that I must be prepared. I also need to make sure I stay as efficient as I was this last lab. Having a question in the back of your mind that you would like to get close to answering is a great way for me to have that push to learn during a lab.
3)I feel like it is called pre-scripted and is pre-scripted because there is already a known answer. You are working to get as close as you can to that answer. So that being said there are certain measures to be followed.
4)When you are ask to go check something out. Or you find something and you want to investigate further without anyone telling you to. Much like, in a project I feel I am the most free to do that as far a science goes.
5)I think that the idea and push from what I am experimenting on is important. I also need an outline which would entail what it is I am experimenting on, what I think the outcome will be, and a means of finding that outcome. There are many other step but those are some basics.

I agree with everything you said. I feel like I had the same experience as you did for question one. For question five don't you think if you provide and outline for an expiriment it kind of becomes a cook book experiment since you do have some instruction?

Tyler Hill

10/8/2012 10:16:25 am

1. What did you learn, or find significant, from this lab experience?
I learned how to work as a group efficiently. By this I mean assigning jobs to each group member and staying on task to make sure that your job doesn't fall upon somebody else.
2. How might this lab experience help you in future learning?
I believe it will be very useful in future labs to know how to measure the meniscus, and how to find the percentage of a liquid is made up of some kind of chemical. Also, knowing how to graph this information will be useful when trying to display the results that we have in a presentation that requires a visual aid, like a POL.
3. This type of laboratory work is sometimes referred to as pre-scripted, or cookbook-like. Why do you think it is called this?
What type of science work would you describe as not being pre-scripted, or cookbook-like?
I believe that this type of work is called "cookbook-like" because the results are already known. Just like when baking a cake, if you use the exact recipe given to you, will end up with a nearly identical result. I think that "non-cookbook" science would include mixing things together to see how they react. If you have no instructions and you are trying to figure something out using methods that are not assigned to you, it's practically the opposite of using a cookbook.
4. Later in our course, you will get the opportunity to design your own experiment. What do you think will be necessary to do this?
Knowledge when it comes to measurements and percentages is essential. If we design our experiment and we get a result that we expect everybody else to get, but we're wrong, then our experiment was unsuccessful. We also need to evenly distribute work among those conducting our experiment or else people will feel unimportant and eventually goof around, which is never safe in a lab.

1. I learned how to find out how much sugar a drink (like soda, juice, etc.), and the mathematics behind it. I also learned who would be a good partner for me when we do a chemistry project.

2. For the future I need to focus much more and stop getting subtracted by stupid things. I'd try to help my teammates/group some more so we wouldn't be struggling with the most simplest things.

3 . I think they call it that because there is a remedy to make somethings and it is already there. So as long as you follow the instructions giving to you, there isn't going to be a high chance of failure.

4. The type of science that isn't already in books. Like do your own thing by expanding on someones ideas, by finding more information on the subject.

5. An already made example of the subject that includes information on it. I would also need a basic understanding of the subject so it would be understandable.

1. In this lab I had an opportunity to practice taking measurements, formatting results, and learning about density. It was good to practice using the pipettes, scale and flask. The substances we used in the lab were harmless, but in future we might be using potentially hazardous materials so its good to have this experience.

2. In the future I might need to know how to use a pipettes, scale or flask, now I know the proper way to handle these tools. More importantly I now know the appropriate way to handle these tools. Further more learning proper lab behavior has made the people around me, and myself safer, by knowing proper procedure there is a smaller chance of making dangerous mistakes.

3. I believe this type of lab can be called a a "pre-scripted" lab because there is no room for discovery. The instructor knows what is going to happen, and everything is set up in a particular way to lead to a certain result. It is very much a "do-blank-followed-by-blank-to-get-blank."

4. Something that would fall out of the range of "pre-scripted" labs would be something like a lab where the results are uncertain. When you don't know exactly what is going to happen during a lab there is a genuine sense of interest and excitement. In an environment where the students are driving the lab that is when "non-scipted" labs take place.

5. In order to create a lab it will be necessary to explain in detail what materials will be needed, and the what steps to take. In order to analyze the data collected it also important to ask open ended questions in order to come to a solid conclusion. Asking open ended questions allows the student to come their own, more meaningful, conclusion to the lab.

I completely agree with the final paragraph. The last sentence is what really strikes me though, open ended questions have no definite answer and really make us think about all the possibilities.

Kim Enriquez

I learned a lot from this lab. I learned how to collect data properly, how to organize a experiment. I learned that everyone in a group plays a role and without those people playing their roles not much can be accomplished. One of the things that I learned that I think will help me for the future was that my group and I had overlooked some details about our data as a result we had to go back and re-do some parts of our experiment.
I think this Lab will help in the future by double- checking my work. Remain on task. I also got helping others out of it. I realized that my work has to be done properly so I can have the ability to help others. I also learned that no task is too small. Simply taking the water up to be measure helps. Or sharing your calculator with your peers can also be helpful.
I think this type of laboratory work is called “cookbook like” because similar to a cookbook it has steps to follow. It gives out a step-by -step process on how everything should be done. It also contained a few tips on how to do things better. I believe that it is also compare to cookbook because if you do not follow the steps provided you outcome is not a pleasant one.
I think the type of science that I would not refer to as “Cookbook like” would be one that I just go out and try. For example if I come up with a question I have been pondering and what to see the conclusion I test out my hypothesis. I think that is what a non-cookbook like science experiment is conducted like. When you have a question and test right then and there. Of course with some background knowledge.
Well, since I know not yet what I would like to test I am not sure what I will be my necessities. I do know that I will need a question. I will need some background knowledge of my topic and create a hypothesis. I will also need to conduct my experiment to see what my conclusion is.

1. I learned that precision is key to the lab experience. If the numbers are off by one or two digits it will create a whole different answer then what you’re working for. It’s better to get a lot of measurement of one thing at least 3 times and spend time getting it precise the first time.
2. The lab in my opinion helps create patience. When using the pipette to transfer liquid it takes a little patience. The long neck of the flask creates a more precise measurement but requires a slow transfer. If you do it too fast you will have to suck out some of the liquid and start over (not all the way). I think that the lab experience helps us to focus more. Due to all the talking I miss a couple of the instructions and meant that we had no break and had little time to do other things.
3. I think that this type of laboratory work is called pre-scripted or cookbook is because everything is written step by step. It tells you exactly what to do and the exact amount. There is not much thinking involved since all the thinking is mostly done for you.
4. Science work that is not pre-scripted or cookbook-like is one where you have little to no structure. All you have is a question and your job is to come up with ways to find the answer. The way to find the answer is to create different methods and then using them to see the product is what you are looking for.
5. Things that is necessary for an experiment is multiple methods to use. After getting the product you separate successful and unsuccessful methods. When you separate the methods you compare the unsuccessful with the successful to see what went wrong in the unsuccessful methods.

Stevon Marshall

I like your overall feel about the journey of doing an experiment whether if it was successful or you just gotta keep on trying until your precise, or at least very close to the goal that your aiming for.

Britton

10/8/2012 01:42:58 pm

In this lab I learned how to follow lab instructions and how to use lab equipment in an efficient manner. I learned how to pour without making a mess and how to use the scale quickly so others could use it too. This lab was helpful because if we do another lab, I will know the necessary skills to learn and continue to grow as a student.
This lab was called a cookbook lab, where everything we needed to know and do was in the handout. It had all the procedures and information we needed to know included, it was created by someone else. A non-cookbook style lab would be one we design ourselves. It could be a hypothesis we come up with and steps we think would be necessary to come to the conclusion. It could also be just experimenting with lab equipment and finding out what happens when x comes in contact with y.
When I get the chance to create my own experiment, I would need to include supplies, directions, and some equations. Other things needed would be a lot of trust from our teacher and possibly a lot of freedom.

Joanna Cardona

10/9/2012 03:14:22 pm

I like the way you described how it would be different from a cookbook like. I also agree with how we need to be prepared for our own experiments.

Sebastian

1. I learned the proper Technique to accurately measure liquids and how experiments like this are preformed in a lab. I learned how to calculate the sugar content in a homogeneous liquid. I also learned that when you want an accurate measurement, to the hundredth. You must heat away all condensed water, on the glass wear you are using.
2. I have learned that patience is key when getting accurate measurements, and especially when transferring substances to other containers. I learned that every thing is much easier when all your lab partners are aware of what step your are on.
3. I think it is referred to as a "cook-book experiment" because the outcome of the experiment is already known, such as a recipe in a cook-book.
4. I would think any experiment that does not have a predetermined outcome
5. Set guide lines for your experiment, and stick to them. Also be precise with your measurements, and be patient.

Francisco M.

10/8/2012 03:49:52 pm

1. What I learned from this lab is how to find the mass of a solution, the volume of solution, the mass of flask + solution, the density of solution, the mass percentage of sugar, and the most fascinating is how to find the mass per serving. Some other things I now know is what the inscribed line on the flask is, I learned what a flask is, I learned how to the scale that measures grams, I learned what a meniscus is. On the computer I sort of learned how to use an excel sheet. I know how to make a scatter plot, remove the border, change the colors, change the points and set up the equation, and the curve and I learned what it is.
2. This lab will help me in future learning in other Physics and Science classes. When dealing with chemicals I will probably use flask and scales. I will use the skill I learned of how to pour liquids; pouring them on an axis. To dissolve a substance I would pour it into the flask using the paper funnel trick I learned then add a little water with the pipette, and then I would shake it. Then keep adding water and stop before it reaches the marked line and fill the rest up using the pipette.
3. I think it is called a pre-scripted or a cookbook-like experiment because there are steps and measures written down on paper. There are specific instructions and expected results and outcomes which is why it is called a cookbook or pre-scripted experiment.

4. The type of science work that would be un-scripted or not cookbook like is having little outline or structure given by the instructor. The instructor would just give the students the chemicals and the instruments and tell them to make a certain reaction. Of course the instructor would give them safety instructions, and supervise them, while giving them advice.
5. If I were to conduct an experiment I would need to know about chemical reactions and more formulas. Doing a lot of other experiments is probably one of the best ways to learn about chemical properties. A work or data sheet would really help me out and writing down the steps.

Michael Gracia

10/8/2012 11:57:11 pm

I agree with your comment about why it's called a "pre-scripted" or "cook-book-like" mainly because it's much like a cook-book in the way you have to follow instructions if you want similar (or exact) results as asked/wanted.

Lukas

10/8/2012 03:52:30 pm

1. I think the most significant thing I learned from this lab experiment was about how careful you have to be when your conducting an experiment. I learned this when we measuring the liquids into the flask. We were extremely careful to not put to much or to little into the flask.
2. I think this lab will help me in future learning with teamwork because in order to get all parts of the lab done we all had to distribute the work evenly. two people were taking the measurements while the other two were writing down the equations. We were really productive.
3. I think it is probably called this because in this experiment you follow instructions, almost as if you were cooking something.
4. Science work that is not pre-scripted is science like observing, and taking a log of new developments each day. Also experiments where you don't know the outcome.
5. I think in order to create an experiment, you need good organization, the correct environment and the right supplies. Without any one of these your experiment won't be as accurate. Also a hypothesis will help structure what you learn from the experiment.

1. I learned that there are excessive amounts of sugar in our beverages. It was slightly horrifying to learn how much sugar we can consume from a single drink. I also learned how to properly use and clean lab equipment, as well as how to precisely measure substances.

2. Learning how to properly measure and record data will definitely help down the road as we preform more experiments.

3. I believe this laboratory work was classified as pre-scripted because the entire process was layed out for us step by step. It left us with little to no room for experimenting on our own, but that is not necessarily a bad thing. Both types of labs are good to practice.

4. Self-experimentation, Observation, and Forensic science are three types of science work I think of as unscripted.

5. To design and test our own experiments I think we should possess a basic understanding of what we want to experiment, a detailed outline, proper equipment to test the experiment and above all, a question we want to answer. A hypothesis wouldn't hurt either.

Elijah Sanchez

10/9/2012 11:37:18 am

Will knowing how much sugar can be in a single beverage make you think about what drinks you buy? I know it made me rethink what I drink.

Jordan

10/9/2012 07:21:45 am

1.) I learned about how much sugar we put in our bodies without even knowing. Also, how excessive the amount is. It is fascinating to know how much sugar is in our favorite drinks that we drink on a daily basis.
2.) This lab experiencecan help me in my future learning because it teaches me more on learning about using these materials. The flasks and how to make a perfect measurement. For labs that require using these things will help me go through the lab much easier.
3.) I think this is called a "cookbook" because it has step by step instructions on what to do and how to do them. You need to follow them carefully or you will not get the best result.
4.) I believe a "non-cookbook" experiment will be something you have not done before. Just experimenting and finding out new things without knowing what the outcome will be. Compare to a "cookbook" experiment where you know what youre going to get or at least have a good idea.
5.) Knowledge about my topic will help me with to design my own exoeriment. I dont want to do an experiment where i know nothing about it. If i know my topic well, i can decide what experiments to do with it. Like what would work, and what wouldnt work.

Paisley Dutcher

1. I was actually really surprised at how well my group worked together. I never expected it to be terrible but I also didn't expect it to run as smoothly as it did with everyone quietly claiming jobs without any word in advance. I also never knew about how to measure the water accurately while factoring in the adhesion of the water to the sides of the flask.

2. The water measuring tips will definitely help me later, also learning how precise you have to be in your measurements when you're doing experiments. In the past everything was pretty loose when it came to measurements, most of the times we could wing it and get the same results as everyone else. That's obviously not the case in chemistry.

3. It's called pre-scripted or cookbook-like because it is very much like both of those things. Everything has already been done and tested before then laid out for you to try. The point of it is to get the same results as the person who did it first.

4. Science that is not scripted would be things like experiments that you can't predict without trying it first. It could also be an experiment in which you don't have a written plan, you just wait and see what happens or (if you know you want a certain result) you can tweak your experiment and observe the different reactions.

5. In order to design your own experiment you'd at least need a topic to work off of. If you're experimenting on the reaction when oil is mixed with water you would need very different things than if you were experimenting with flammable substances. Beyond that you'd just need an expectation of what you want to achieve and what you plan to do/try in order to achieve it.

1) I learned how to measure things and find its mass and percentages and things. What really was significant for me is how we discovered how much each like soft drink that our group choose had of sugar in just 8oz like you said and to me that would be the most significant from this lab.

2) This lab experience of learning to measure things can help me in the later future of how to maybe calculate and measure different types of things in the world, for example I can put this learning experience into when prescribing medicine and measuring how much of each medicine or substance you put to make the medicine for a patient. This can also help me by knowing how to measure and help my group or even help other people that find it difficult to measure things.

3) I think it was pre-scripted or cookbook like because a packet was given to us and if you take time and effort to read the packet it showed you step by step how to do in this lab, this also includes all the formulas you will need to use in the lab and what you will be looking for and how you should find. That's where I think it's called a pre-scripted lab.

4) I would say that the type of science work ranked or put under the category of not being pre-scripted would be the one that you are given little information or only enough information you need to start the work and you or your group have to work together and find out how to solve this work and only ask the teacher when they are stuck or they need help understanding something at a point.

5) I think you will need to really think of what you're going to do because if you just think out of the blue as they say then you later realize that you wanted to change something and it will be already to late. Another thing you will need to know is how will you solve or find the answer to your experiment and what formulas will be needed to find solutions to the problem. You will also need the equipment you will need to conduct your experiment and be confident of what your doing and have fun :)

Alyssa Abeyta

I think like you went into a lot of detail and really explained the things you learn. One thing i noticed was that if we were to create our own expierence or whatever the question was for the last one, you really know what your doing and what you would have to do to make your own expierence but at the same time make it a learning expierence.

Bryanna Rivera

10/9/2012 11:53:08 am

1. This lab experience really showed the importance in accurate and precise data collection. It was important to measure the water a few times so that we could get an accurate measurement. I was very surprised with how smoothly my group worked together. We all "self assigned" roles and had a good conveyerbelt- type work environment.

2. Learning how to get an accurate measurement will definitely be a large part in future labs. Also figuring out a good system (as a group) to work by will be helpful for future experiences.

3. This is definitely called "cook-book" because we follow the directions as we would a cookbook! There were very specific instructions that you had to follow in order to get the end product. Somebody already did this before, and we are simply trying to get the same product as they did.

4. I would consider "field" work not as scripted. When you go out of the lab, you probably dont know exactly what is coming. Although, experiments do have to be planned out to an extent; you can't just roam aimlessly looking for nothing.

5. Well, to create our own experiment, we need to first figure out what the end product should be. Then, based on prior knowledge, math, science, or whatever- plan out how we would go about achieving that goal.

1) I learned during this experiment how to find the amount of sugar in a drink, I also learned that energy drinks have as much as 54 grams of sugar :0. Thirdly I learned how to accurately measure with a volumetric flask.
2)2. This lab will help me in future learning in other Physics and Science classes. When dealing with chemicals I will probably use flask and scales. I will use the skill I learned of how to pour liquids; pouring them on an axis. To dissolve a substance I would pour it into the flask using the paper funnel trick I learned then add a little water with the pipette, and then I would shake it. Then keep adding water and stop before it reaches the marked line and fill the rest up using the pipette.
3. It's called pre-scripted or cookbook-like because it is very much like both of those things. Everything has already been done and tested before then laid out for you to try. The point of it is to get the same results as the person who did it first and ensure that the method used throughout the class was the same so we didn't get skewed data.
4. I would think any experiment that does not have a predetermined outcome or a lab that had not been compleat lay laid out with step by step instructions
5. I think in order to create an experiment, you need good organization, the correct environment and the right supplies. Without any one of these your experiment won't be as accurate. Also a hypothesis will help structure what you learn from the experiment.

1) I find this lab experience showed taught us the basics of doing labs, and what happens in labs. It was interesting finding how much sugar are in energy drinks especially Monster.
2)This lab helped us with measuring and accuracy. Without accuracy we can’t be precise when you measure.
3) Cookbook labs get their name it’s already recorded before testing.
4)I would call going out in the field and making hypotheses about stuff isn't cookbook. And if I would design my own experiment, it would be something where we do hand on hand learning.

Marco

10/9/2012 12:47:50 pm

Wait never mind, not hand on hand learning. I want a project that never happened at HTH before. Making hypothesis about what happens( For example: Pouring bleach to ammonia taking whiffs of the smell. Don't do it.)

Hi, I was looking at your last comment and I was wondering why you felt that the experience wasn't 'hands on learning' enough? Also if you were to make an experiment what would you do it on and why? Another thing I want to add is that I agree with your statement on the lab teaching us the bascis of how to conduct a lab. Nice Answers! ~Sofia

1) From this lab experiment I realized how important accuracy can be, especially dealing with substances. Another thing I realized is how smoothly it was to work with my group members, even though one is person I've never worked with. While the other was once a total stranger.
2) This lab will help me in the future by being more aware of the tools, substances, and even my surroundings. Plus being accurate or even becoming close to the it.
3) I think this was a "pre-scripted" lab, because we had all the instructions on what to do for the experiment, without asking for assistants.
4) A type of science related experiment that is not "pre-scripted" would have to be you (Andrew) telling us what you want created without giving any hints on what to do (meaning tools, substances, etc.)
5) In the future when we design our own experiens we'll need to know what is expected of the assignment, aware of substances, and maybe a test run to get the feel of things.

I seems that this lab experiments made you more aware of you surroundings like the people in your class and the materials. Will you put this awareness that you learn into the outside world or is it something that would do inside a lab?

Ana

1. This lab really showed me the importance of making sure that your data is accurate. Previously, I have never been asked to take measurments more than once inorder to find the most accurate restults. I also leared how much sugar is in different drinks and, on a side note, I learned how sweetness, bitterness, sourness, and saltiness effect our tongues.

2. This lab will help me in the future by teaching me to always be as precise as possible when it comes to my labs. I realized that if you are as close to right as you can be, it makes your labs more correct over all. On top of that, I learned how to properly use glassware.

3.I think this kind of lab is called a 'cook-book' lab because it tells you exactly how to do the lab. You are given step by step instructions and it is very hard to mess up the lab.
4. I think labs in which you don't know what the outcome will be would be considered not cook-book-labs. Also, a lab where you were not given step-by-step instructions would be considered a not pre-scripted lab.
5. I think there are many things you need to plan your own successful expiriment. You need to have good organization and be able to time manage. Also, it is important for you to know what supplies you need and how to use them correctly.

Fedja Milz

10/9/2012 04:01:51 pm

I agree with you first statement. It is important for people to actually experience things like measurements, calculations, etc. in a lab setting. It really teaches people about data collection.

Giovanni Cassarino

1. After doing this experiment, I was quite surprised how dense a grain of sugar actually is. Using the sensitive scale in class, we poured sugar into the vials and the scale picked up every grain which was quite amazing. It also makes you think about how much sugar is actually in the things we consume daily. What was really interesting is that now we can all calculate how much sugar is in any beverage if we put the time and effort into it.

2. This lab experience will definitely help me in future learning because since it was more of a pre-scripted experiment, it gave me the skills and practice to be able to do the same things on my own without directions. So when we do get directions for experiments or other assignments, problem solving and experimenting with different ideas will come with ease.

3. This type of lab may be called Pre-scripted, or cookbook-like because it was very specific in what to do. Each step was spelled out for us, and the teacher knew what to expect as a result, almost like a recipe or "Cookbook".

4.A non- scripted lab is most likely the opposite of a cookbook lab. Meaning that there are limited directions and the general idea is passed onto the students. The predetermined result is non-existent and the result is up to how the student preforms the experiment.

5. Designing an experiment is probably pretty difficult, since you have to design what your goal is, then how your going to get there. When I get a chance to make an experiment, I'm going to focus on making a clear set goal although leave room for the students to actually 'experiment'. I think it's important not to have a pre-scripted experiment because that would take away the whole experience of experimentation.

Isak Nuhic

1. The most significant thing i learned while doing this lab is probably being patient, and working carefully. I learned to work carefully when i had to pour the sugar in through the funnel. The scale was also very precise so that added to working very carefully and precisely.
2. This lab is going to help me work with other people just because it took for all of us to cooperate and work together as a team. We all had a little job that we had to do in order for the experiment to run smoothly.
3.Since we had to follow instructions.
4. Natural science is not pre scripted. Science in which you are free to explore things and observe things hands on.
5. In order to create an experiment you need to know somewhat of what you are looking for. You cant just blindly start doing an experiment. You need to be organized aswell.

Matt Larson

10/9/2012 01:54:04 pm

1. One one the most important things I learned from this lab experiment was how careful and precise you need to be when you measure anything. When our table had to measure the water we had to slowly poor it in at an angle and once it was almost to the top we had to slowly put crop by drop so it would be the most precise we could get it.
2. This lab experiment will for sure help me in the future because I now know how important it is to get precise measurements and also making those precise measurements will help me know what to do the next time we need so make measurements in class.
3. I am not too sure on why it would be referred to a pre-scripted, but it's probably referred to as cookbook-like possibly because when you cook you need to make precise measurements of food in order to make it right. If you were to make a cake, and used 5 cups too much of sugar, 3 cups too much water, and 4 extra eggs, it's probably not going to taste all that great. Same in the lab, if you put too much or too less of a chemical it can really effect the experiment.
4. Well something in a lab experiment that's not pre-scripted or cookbook-like for one could be any normal lab test. When you cook something you know what your going to make when its done, the outcome of the final product. But in lab experiments you are "experimenting" on substances, not know whats going to happen/ the outcome of the experiment.
5. Well for one you will need to know your lab safety. I'll say that's one of the most important ones because without lab safety anything bad could happen. another thing you would need are the right tools. Without the right tools you experiment would most likely be wrong. Also you would need to know what your using for sure. If your designing our own experiments we cant just pick up a random chemical expecting what we want to happen, happen.

1) What I personally think that I learned from this lab is figuring out how much sugar are in drinks and how to measure it. I learned how to use the scale to weigh certain things. I figured out how to get a close precise measurement of what I was weighing, I had to find the average of each different measurement I had. I learned how to find the mass of a solution. I learned how to find the mass percentage of sugar in a solution/drink. I learned how to use an excel sheet, I learned how to graph things on it and how to get the equation of the graph.

2) This lab experience that I had will help me in future labs with correctly poring substances in a flask by using a paper funnel or a funnel, correctly weighing chemicals and weighing it a couple times to get a precise measurement. In future labs I will know how to pour things like chemicals or water correctly in a beaker or flask, filling it up close to the line marked on the beaker and then finish filling it up using the pipette.

3) I think this lab was like a cookbook/scripted because we already new what to do we were told what to do and how to do it. We had to do everything step by step following directions to make sure nothing goes wrong.

4) The way I would describe a non cookbook/scripted like lab would be something that we made up on are own its more of an experiment you don’t know what’s going to happen. You will still be given safety instructions to make sure everyone is safe.

5) What I think will be necessary to create our own labs will be to write down some steps on what we are going to do and brain storm some ideas on what kind of things you want to do, for example writing down Ideas like if you want to do a chemical type of lab or you want to do a lab with safer things like water. Then when you decide what your going to do write down some steps to follow on how to do the lab.

Sergio Ramirez

10/9/2012 02:20:28 pm

When doing this lab experiment I learned that it is important to be accurate and have lots of patience. I also found that it is important to know what you're doing and and know the criteria of the experiment that you're involved in. This experiment is going to help me in the future because I now know how to accurately measure things right using different beakers and tools. It will help me whenever I have to measure anything or incase I ever have to do this again. I think this experiment or lab work was really planned out and organized, so it was really cookbook-like. We were given detailed instructions and good information so that the experiment went on correctly. I think an experiment that is not very cookbook- like is the lab work when we messed around with the dry ice. In this experiment we had a lot of free time, and not all that much criteria. We got to experiment with the dry ice on our own and learn for ourselves the things it did. If I conduct my own experiment I think I would like to make it more like the oobleck and dry ice experiments. They were really fun and we had a lot of free time during the experiments. We got to learn on our own, and the criteria was learned during the experiment. All that was given to us was the materials and safety instructions of what not to do, which was really nice. Overall I would like to have other experiments just like those.

John Preciado

10/10/2012 03:37:59 pm

It sounds like you got a lot of good measurements in your experiments and your right when you say you are gonna apply your knowledge towards future experiments as well. As for your own experiment, it sounds lik you had a lot of fun with the oobleck and the dry ice experiments. If you could somehow combine those two awesome experiments, I would definitely want to conduct that new experiment

Jorge

10/9/2012 02:54:07 pm

1) I learned how to properly measure mass and volume. By properly, I mean measuring repetitively with precision, then taking those results of each measurement and finding the average in order to get a solid, accurate measurement. What was also significant about this lab was what can be figured out with volume and mass. I was able to calculate the density, mass of solution, and the percentage of sugar in the solution.
2) This experience will help me later on in my learning and in future labs. I learned that in order to get good results, you need patience and focus. I also learned proper lab behavior and how to use tools such as pipettes, scales, and a variety of flasks.
3) I can see why this type of lab work is referred to cookbook-like. When you cook, recipes usually involve precise measurements, various containers and pouring techniques, and patience. The steps need to be followed in order and the more accurate your measurements are, the better results you get like when you cook. Also, in this type of lab, you knew the results you were aiming for, especially the instructor.
4) I think any type of science work that is unprecedented can be described as not being pre-scripted. This means science that doesn’t come with a worksheet or instructions. Where you’re not being told what to look for and what to expect, as much as just observing and discovering your own answers.
5) In order to design my own experiment I think I would need to start with a simple question like, what causes explosions? After I have a question, I’d expand on it, observe what revolves around this question, and ask more questions like, when a grenade goes off, is it the same reaction as a shaken soda bottle? I’d Come up with a theory or hypothesis of what I think is going on and test them. I would be looking for my own answers.

miles

10/10/2012 02:27:25 am

I can tell you did a great job measureing because you took everything correct and by the way you were explaining it. I agree with all your statements that being 100 percent accurate will pay off adn to be as precise as possible. I also think your experiment is a great idea and i think you would do magnificent in that one too.

Joanna Cardona

10/9/2012 03:11:07 pm

1. What did you learn, or find significant, from this lab experience?
In this lab I learned how even though you have diluted sugar into water it is not going to add all the weight of the sugar. I found it significant how we learned how we got to work in groups and how we were trusted, without any one getting into trouble or someone being foolish.
2. How might this lab experience help you in future learning?
This experiment may help us out in future if we were to be working on a lab we would know ow to know where the exact measurements should be and the exactly how to pour the solutions into the flasks.
3. This type of laboratory work is sometimes referred to as pre-scripted, or cookbook-like. Why do you think it is called this?
I think it is considered to be like a cookbook because they are giving you exact instructions and you know what to expect and that is what you do with a cookbook, you follow instructions correctly and you should get your exact results.
4. What type of science work would you describe as not being pre-scripted, or cookbook-like?
I think that maybe if we were just given some sort of instructions we could get done and then we would write down our observations and our results it would be more different then a cookbook or pre-scripted.
5. Later in our course, you will get the opportunity to design your own experiment. What do you think will be necessary to do this?
I think it is going to be necessary to know what you want to do exactly, also you should experiment it yourself first in order to give it to someone because you could be giving them something that may not work.

Britton

10/9/2012 03:45:51 pm

I liked how you said not being foolish is a big part of lab work, I agree. I also agree with what you said about cook book labs and how they are simply instructions that need to be followed. You seem to have a good idea of the expectations in Andrew's class.

Sierra Renna

10/9/2012 03:24:41 pm

This was our first lab was a great experience. My group was very productive and a great learning experience. I had an amazing group. We all worked together very well and we where very productive. One thing that stood out to me was when we where trying to measure the water with the sugar in the Volumetric flask we all double checked each others work to make sure that we where each on the right track. The whole experimental time we where looking out for one another. This lab experience will help in the feature because I now know what works for me and how to help my other group members.
I think that this kind of lab is called a pre-scripted lab because that’s what it is. It is a lab that has the whole thing laid out for you. You know what to do how to do it and what you should come out with. There was a guideline and a protocol that you had to fallow. An example of a non scripted lab would be like being out in nature and trying to observe a bear, you don’t know what the bear is going to do so there is really no way that you can plan a lab biased off of what the bear is doing.
I think to build my own experiment I am going to need a lot have back ground information on the thing that I want to experiment on. I will also need information on similar experiments that have been conducted in the past. I would need to know what kind of materials I need to use to conduct that experiment. Finally I would need some kind of what to analyze my collected information.

Fedja Milz

10/9/2012 03:57:20 pm

1. What did you learn, or find significant, from this lab experience?

I learned how to check my calculations, and use lab equipment more efficiently with my team to avoid miscalculations due to spilling for example.

2. How might this lab experience help you in future learning?

I got to learn a couple of tricks on how to use lab equipment, and how to work with a team more efficiently.

3. This type of laboratory work is sometimes referred to as pre-scripted, or cookbook-like. Why do you think it is called this?

I think it is called this because the lab is step-by-step. You need to follow a set of directions to get the result you want, like cooking.

4. What type of science work would you describe as not being pre-scripted, or cookbook-like?

I would say that that would be a lab where people could openly execute their own experiments. Probably something with out mixing together stuff, but more of just experimenting on a subject freely, like the oobleck.

5.Later in our course, you will get the opportunity to design your own experiment. What do you think will be necessary to do this?

I think that it is important for the designer of these labs to step into the shoes of whoever is executing them, and think of the most logical way to present it.

Ana

10/10/2012 03:47:39 am

I thought it was interesting how you described a non-prescripted lab as one where you don't mix things. I never would have thought about it that way, but now that I think about it I agree. I suppose it would be hard to not have a planned experiment and still know exactly how much of a substance to mix and such.

Also, I agree completely with what you said that the designer of the lab has to step into the shoes of the person who is going to perform the experiment. That is probably why people who write up experiments always have to perform the experiment before publishing it.

Madison Clark

10/9/2012 03:58:36 pm

1) In this lab experience I learned even more about how much sugar is in the drinks that we have almost everyday. Which is pretty gross because you don’t need 50 grams of sugar for energy yet we rely on it so much. I also thought that they way that we recorded everything down was significant, because usually we write it down on a random sheet of paper and never really keep it but this lab had us recording our information like you would if you were in a real lab. So that was fun
2) I think that this lab will help me in the future by showing me the correct formatting for recording my findings during experiments. And I also think that by doing these labs I’ll get used to doing these types of experiments and I grow to love them more.
3) I think its called pre-scripted or cook book like because it told us exactly what we should be looking for and what measurements and solutions to take and use. Experimenting literally means just trying something you’ve never done before so if your lad is pre-scripted then obviously it’s not something that hasn’t been tested before. There is pros and cons to that method
4) Like I said before, or above, non pre-scripted science work would be testing different experiments and not knowing what the outcomes would be. Almost taking chances with each experiment.
5) I think that as students it’s important for us to have a more hands on learning experience especially in chemistry so I think that by conducting our own experiments we would be learning how to teach others in a sense.

Bryanna Rivera

10/9/2012 04:03:32 pm

Hey Madison!
I really liked the point you brought up about writing on a significant piece of paper- I feel like students often over look that.
Also, I totally agree with the hands on learning aspect of chemistry- its also the more fun side!

Sofia Bresciani link

10/9/2012 04:03:00 pm

1. The things that I learned from this lab are how to go about in a lab setting with out the teacher constantly having to tell us as students what to do. Also how to take turns with the equipment and measuring. It helped show us what kinda of calculations we should be taking and the formats that should be used in a lab.
2. I feel from having done this once next time we have a lab such as this one it will be easy for us as students to get into the learning and work much faster. Things would be a lot more organized. Also in all us as students will be more focused by having had the experience before.
3. The reasons I believe this kind of experiment is considered a cookbook-like is because the work comes with instructions, and that there are answers previously found out. Also there is not room for own experimentation.
4. The kind of science work I would consider not being pre-scripted is work like where you put in a situation and you have to figure out why something works the way it does and prove it. Thats when I feel like its non-prescript. Also when your forced to learn on ur own, and your in charge, and there is no chart you have to follow.
5.Some of the things that I think that will be necessary in our future project is obviously a plan on what you need to get done and when you need to get it done. So with that you can stay on task and finish your project with ease and not end up with a badly put together final draft.

miles herrera

10/10/2012 02:20:20 am

1. The thing that I found was most important about this lab is that patience and to be steady. In our group we paid really close attention to how much sugar we added every time and if one little grain would be out of place we would restart. I never thought I could do this as well as I did. We had some good surprises that day and everyone had fun.
2. I think this lab in particular could help me because I’m always rushing to get things done and I do not make precise and perfect moves.
3. I think this type of lab instructions works great because everything is laid out for you, very straight forward while you’re working all the way through the lab.
4. I think none “Cook book” lab instructions would be more like the last lab we had with oobleck because you never gave us strict or precise measurements. In the oobleck we had to go a little more outside the box and figure it out measurements by ourselves. I like both ways and techniques but I think it depends on the lab and what specifically we will be doing.
5. I think I would prefer to have the “cook book” instructions and layout. That would be if I wanted to have a perfect and straight forward project in the end; if I were to not then I would anticipate something I would expect and it think that would be cool as well.

Jorge

10/14/2012 11:08:23 am

I completely agree and can relate to your answer on number two, about rushing to get work done and not making precise moves. I also think that cook book like lab would be easier, but one that’s not like a cook book could potentially be more beneficial. In my opinion, It would be spontaneous and make us challenge ourselves a little more.

Isaac Gutierrez

10/10/2012 04:00:08 am

1. I think this lab was kind of boring the only thing I really took from this is how to use the glasswear properly
2. It shows you the basics of making your own lab.
3.I think this is called cookbook because it is step by step with one correct outcome and no variation except for wrong math.
4.I think that a non scripted means you actually have to use a lot of problem solving and it is not step by step and a lot more free to experiment.
5. We need to test our lab to make sure it is safe and we know the outcome to make an experamint you have to test it.

John Preciado

10/10/2012 04:58:16 am

1. In this lab, I learned about how to calculate more acurate measurements as well as learn about different amounts of sugar content are in everyday products that we purchase and consume.
2. This lab will help my future learning because I can apply the equations and factors I used to calculate my results, into my experiment and results in the next lab
3. It is called pre-scripted because all of the information and the equations needed to successfully perform the lab properly was already there when we started, and it explained step by step what to do next like a cookbook
4. Some science work we could do that is not pre-scripted would be creating and conducting our own experiments
5. In order to create and conduct our own experiements, we need to have the knowledge to create and think about our own problems, as well as take workshops where we can create our own hypothesis and our own experimetations and come up with our own results. We would need to practice multiple times before we could ever create and conduct or own experiments.

Marisela Diaz

10/10/2012 08:24:01 am

What did you learn, or find significant, from this lab experience?
The most significant thing learnt from this lap experiment is that there is a lot of sugar in the drinks. For example I learnt that Monster has more sugar than Coke.

How might this lab experience help you in future learning?
This could help me if I ever have to do other experiment or project like this. Also I would teach me not to drink monster.

This type of laboratory work is sometimes referred to as pre-scripted, or cookbook-like. Why do you think it is called this?
I would think its cookbook-like because your dealing with sugar and nutrients and how that effects you.

What type of science work would you describe as not being pre-scripted, or cookbook-like?
Non cookbook-like type of science work would be like mixing different chemicals together.

Later in our course, you will get the opportunity to design your own experiment. What do you think will be necessary to do this?
I don't know.

1. I think pertaining to significance, learning how to understand how labels on foods or drinks are calculated is impotant to understand more on what you are eating.
2. Using the knowledge from the Lab could help you calculate things in the future, if needed.
3. This kind of Lab is called pre-scripted, or cookbook, because all of what you need to find out is already there. It's layed out for you.
4. Trying to find out the amount of startch used for bread, or how much iron is in meat, without having things that you need to find written out for you.
5. Understanding on HOW to find whatever you need to find, without having a paper telling you EXACTLY what you need to find in steps.

Matt Larson

10/10/2012 01:01:55 pm

Hello person I don't know. I agree with you on all of your statements for each question, but mainly question 2 and 3. For question 2, that's basically what I said, because that's really the only thing we could take from this experiences. Also what you wrote for question 3 was kind of what wrote. If you someone tells you to make a cake but you have no ingredients, you can't make it, same as in the lab. If Andrew tells us to make so and so but doesn't tell us how, it makes it practically impossible.

Mason

10/11/2012 08:12:20 am

1. I thought that this lab helped teach us to work more as a group than just alone. It also tought us (or just me) how to figure out the amount of sugar in a drink (other than just looking at the nutrition facts).
2. As I said before it will help me work in a group and also how to measure that sugar content in drinks.
3. I think this lab is known as a cook book lab because in a cook book you follow the directions exactly just like in this lab.
4. I think that the lab we did with obleck was non cook book like because you gave us complete control of the lab unlike the sugar lab that was very cook book like.
5. First I think that the expariment will have to work and it will have to have a cool ending. Second it will have to be easy to do and not time consuming. Finally it will have to be the best expariment we did in the whole class.

Miguel Ramirez

1) What I found significant about this lab is that the exact amount of sugar can mess up the lab. You need to be percise and careful when weighting anything.
2.) This lab will help me in the future when someone asks me the amount of sugar is in a beverage or in college when they only gve us the lab and no notes, I will already know what to do.
3) I really do not know why they call them that.
4) Probably a lab with a hypothesis.
5) I think I will need to describe the lab in detail and make it fun because I personally would not like to do a boring lab.l (not saying andrews labs are boring ;) )
