Remember, you are answering the following questions:
- What did you learn from this lab?
- What do you now know about molecules?
- What questions do you now have?
Your reflection should be about 1/2 to 1 page long.
I look forward to reading your responses.

What I learned was that in photosynthesis oxygen and carbon dioxide molecules both disassembles and put its selves back together to crate a glucose molecule. I also learned that 6 oxygen and 6 carbon dioxide molecules are needed to make one glucose molecule. Now I know how a molecule looks like. And what atom goes were on the molecule like water is hydrogen and oxygen. A questions I have is could any two molecules disassemble and go back together (water& gold)?
“It’s All In the Shape” Lab Reflection
I have just completed a lab called “It’s All In the Shape”. I loved doing the lab and I learned a lot from it in the process. To make each compound we used gumdrops for the elements and toothpicks for the bonds. I think that using gumdrops to perform this experiment was very helpful because it made me actually see what was going on instead of having to imagine it. I learned that doing an experiment may not always be as easy as it looks. This experiment was like solving a puzzle. I really had to use my imagination to know how to fit the pieces of water and carbon dioxide into the puzzle of glucose. I learned that I had to be very patient, but that in time I would understand how to figure out the puzzle. Instead of just knowing the chemical formula for photosynthesis and cellular respiration, I now know what actually happens when those things are done. Teamwork was very important in this experiment. My team had to work together and divide up the work to complete the building of the models as quickly as possible.
While doing this experiment, I learned about molecules and their structural formula. One thing that I learned is that molecules break their bonds and form new compounds. For example, the experiment we did was to make glucose and oxygen out of carbon dioxide and water. The carbon dioxide and water had to break their bonds to form the glucose and oxygen. Another thing I learned was that molecules really have a three dimensional figure, not just the two dimensional pictures that I usually see. I also learned that six water and six carbon dioxide molecules are needed to make one glucose molecule. I learned that if a compound has more electrons that bonded together, it will be harder to break. I think that it is very interesting that each chemical compound has its own unique structure and shape. For example, glucose is like a hexagon with branches and water is more of an “L” shape.
I have a few questions about molecules and about this experiment. One question is what would happen if there was one extra hydrogen, for example, and it did not fit into the molecule you were trying to make? How does each element know where to go in a molecule of glucose? How long does it take for one molecule of glucose to be formed? Does it take longer for one molecule of glucose to be put together or taken apart? When molecules are formed, is there ever something wrong? Is there is ever not enough of a certain element?
I really had fun doing this experiment and I hope we could do something like this again. Using the gumdrops made the lab very interesting. The gumdrops tasted good too!

All my drawings are in the packet.
Photosynthesis is the process that plants perform to use energy for themselves and in the process they create energy for us humans. The chemical formula for photosynthesis when it is turned into glucose is H2O+CO2-light-C6H12O69(glucose)+6O2
Cellular respiration is the process when humans use their energy, (sugar+oxygen) and then turn it into it’s original compound , energy that plants can use, (water +carbon-dioxide). The chemical formula for it is C6H12O6+O2‡CO2+H2O+energy.
What we did as scientists was try to figure out how Glucose becomes different lone properties again. We used the gumdrop lab as our models. Each different color gumdrop we used was it’s own property (ex.white=oxygen)
We put together Glucose as a gumdrop model, then put together one of each model we would be left with when we were done. We tried to fit those into the Glucose sequence.
Eventually we ended up with 6 waters and 6 carbons.
I thought the gumdrop lab was a very good way to figure out what was in glucose, how it is made and how it is used. I thought it was fun because it was hands-on and I’m sure most of the people in our class are hands-on learners, like me. I learned many things from this lab. Before, I had always thought of this whole process in sort of a different sense, when I did it this way I realized how it actually worked. I know that heat is just molecules moving around . I have questions about other structures and how our lungs use the oxygen particles.
I really don't like gumdrops but the experiment was fun to do. And the fact that I was doing a high school based lesson was a satisfying one. Oh! I learned how to make visual aids for chemical compounds. I now know that some chemicals that we use every day have very complicated structures. Like oil. The questions I have are... Is there an application that I can use on the computer that lets me model 3d chemical compounds and interact with them.
I thought that the experiment was really fun and tasty. Even though we got all sticky and smelled weird it was fun. I learned alot about moleucules. Before all I knew was H2O. I think that we should do something like this again. I didnt know that molecules break apart but not completely apart to form a new moleucule.
I thought the experiment was really fun, even though my hands got all sticky. I learned a lot about molecules. Before the only molecule I knew was H20, now I know lots of other molecules besides that. One thing I learned in this lab is when molecules break their bonds they form new compounds. An example of that is when six water and six carbon dioxide molecules break apart to make a glucose molecule. Another thing I learned about molecules is that the strongest molecule breaks last because it requires more energy to break. Overall I really liked this experiment because it was fun and I learned a lot. I would like to do an experiment like this again soon.

The first and fore most important thing I learned from this lab is you can create different elements from toothpicks and gumdrops. I learned in science there are many different ways to show chemical reactions, compounds and elements. For example:
Glucose and oxygen (Goes to) carbon dioxide and water and energy: can also be shown as:
C6H12O6 + O2 (Goes to) CO2 + H2O + ATP: can also be shown as:
Lots of toothpicks and color coordinated gumdrops.
Another thing I learned from this experiment was how complicated molecule structures were. When we had to build oil and it took ages. Just think the next time you spill oil on something, (hopefully not anytime soon), how many different things are in oil and how many are reacting.
Another thing I learned from this is how frustrated scientists must get they are trying to put chemical reactions together. When we tried to take apart glucose and oxygen and I could barely do it. But when we learned the stronger the bond the more energy you need to break it, it started to make more sense. That would mean Carbon breaks off last and Hydrogen breaks off first. Once we stared breaking them off, we started creating water and hydrogen dioxide. It was really cool.
Some things I learned about molecules are they react with each other all the time, whether it a reaction that explodes or bakes chocolate chip cookies. They also very intricate and precise. If you change one atom they become an entirely new one.
Even though this lab was really fun and a learned a lot, I still have some questions.
If chemical reactions are happen in your body all the time, what happens if something gets messed up, will you blow up or something? Is cellular respiration more complicated the photosynthesis or visa versa? How do the molecules know how to break off in certain spots when they are going through a chemical reaction?
I had a great time doing this lab and the gumdrops were yummy.
I learned basically that it is betterr to learn when you phisically make that thing.
I learned what molecules look like, and that c6 actually means 6 carbon molecules. And I learned that molecules break their bond and start new ones.
One question I have is how long does it take for the molecules to form together?
When the molecules form together, do they ever form something they had'n't planned to??

I learned a lot of things from this lab. The most important thing I learned is that everything is made up of molecules and bonds. For example, in glucose, there are hydrogen, carbon, and oxygen atoms. When each atom is by itself, it doesn’t look like it could be put together with another atom. When you really think about it, almost every molecule or bond is made up of carbon, hydrogen, or oxygen. I also didn’t know about bonds before this lab. I learned that bonds are atoms that are connected to make bigger molecules.
After we finished the lab, I knew a lot more. I now know about what molecules’ different substances (elements) are made of. I know now that cellular respiration works because of the shape of the molecules, like locks and keys. I know the order of how bonds break, the weakest first, then the next weakest, etc, ………….. and then the strongest breaks last.
I really don’t have that many questions about molecules but I do have a few. One of them is how is an molecule made? I mean, I know what they are made of (elements, atoms), but how do they become what they are? Also, if there was one change in a chemical reaction, like photosynthesis, if you took away one element of it, would it still be the same???

“It’s All in the Shape” Lab Reflection
I just finished a lab called “It’s All in the Shape” and learned various things. For this experiment we used toothpicks and gumdrops for props to create molecules. We created molecules with color coordinated gumdrops and toothpicks. I learned that you can show chemical reactions using different things such as gumdrops and toothpicks. I thoroughly enjoyed this lab because it was really hands on and fun to do.
I learned from this lab, about molecules and atoms and which atoms make up which different molecules. I also learned how photosynthesis and cellular respiration take part in molecules and atoms. I learned many different chemical formulas and what takes place in a molecule. For example, I learned that the formula for glucose is C6H12O6 because there are six carbons, twelve hydrogen and six oxygen bonding together to make one glucose molecule. I learned that molecules are 3 dimensional and have chemical reactions within them. I also learned that within a molecule, atoms bond and break to form many different things.
I now know and have learned many things from this lab. One thing I know now is that in the photosynthesis process, bonds between atoms in water and carbon dioxide break apart than bond together in different pieces to form glucose. In the cellular respiration process, bonds break in the glucose molecule and bond together to form water and carbon dioxide molecules. I now know if more atoms are bonded together, the harder it is to break. I now know how chemical reactions work and not just what they look like drawn.
Some questions that I have about this lab are, how long does it take for one glucose molecule to be created from water and carbon dioxide molecules? What if there is an extra atom not being used to make the molecule? What would happen to that extra atom and would the molecule still be made?
I overall really loved this lab and love doing hands on experiments like we did. I thought gumdrops was a really good way to express these chemical reactions and it really made sense to me because of it.

What I learned from this lab was that not all molecules are somewhat in the shape of a line. A few are in circles such as glucose. Another thing I learned was how to break down carbon dioxide and water to make glucose as well as reverse the process. In addition, I learned that hydrogen bonds are the weakest, then hydrogen and oxygen finally carbon as the strongest.
I now know that molecules break apart to form new molecules. For different compounds, more or less molecules are needed to create it. A cool fact that I did not know was that any molecule that has hydrogen and oxygen in it is organic.
I did not really have any questions about the lab. While we were doing the lab my questions were answered and more. The only question that I do have is a little off topic and it is; what is the longest chemical formula and what chemical is it for?

I learned that this college level stuff is hard, or is high school well its still hard.I now know that carbon , oxygen and hydrogen are commonly found in biological molecules.Do molecules take time to break apart or is it a quick transation
"it's all in the shape" Lab Reflection
I just finished a lab called, "It's all in the shape" and learned a lot of things. In this lab we did an experiment on molecules. We made models of the molecules, oil, glucose, water and carbon dioxide. We made these molecules out of toothpicks and gumdrops. I learned that you can show what molecules are and what elements they are made of just from toothpicks and gumdrops! I also learned that cellular respiration and photosynthesis take part in the molecules and atoms. I learned that all of the chemical formulas like, H20, C02, 02 and many more stand for something. For example H20 stands for one hydrogen and two oxygens. This chemical formula makes up water. All molecules are chemical formulas that means something not just two letters and a number.
From this lab I now know so many things. One thing that I learned is that glucose is just carbon dioxide, water and oxygen. Because when you break apart glucose you will end up with water, carbon dioxide and oxygen. Some chemical formulas (like glucose) are just other chemical put together and more of them. Another thing that I now know is that the stronger the bond the harder it is to break. I now know that chemical reactions are not just a couple of letters and numbers its a lot more and confusing than that.
I really liked this lab because it was really hands on and I got to see what the molecules looked like and what they were made up of. A question that I have is, who first discovered what molecules are and what they are made of? In the end i really enjoyed this lab. It was really fun using the gumdrops and toothpicks as models. I hope that we will get to do something like this again.
i CANT find any good info on the three questions due fri
anybody have good links rocker
