What information I needed to know before doing this experiment:
This experiment showed me states of matter. Dry ice is a frozen liquid, which becomes a solid. I learned some new vocabulary words like Sublimation and Deposition. Sublimation occurs when solids becomes a gas. Deposition occurs when gas becomes a solid. I learned how to handle dry ice before doing the experiment because the ice is so cold I could get frostbite. Also, I learned how to measure a vapor by measuring the circumference of the balloon.
Looking Back: What happened? How did your experiment turn out?
We had a block of dry ice and passed it around the table. Our goal was to try and measure how much more gas there is than there is solid. We were successful.
Did it work?
Yes, we measured the circumference of the dry ice block and then wrote it down. It was about .5 inches. Then we put the dry ice cube into a balloon and waited for it to sublimate. When it was done we measured the circumference of the balloon and it was 8 inches. The gas was 7.5 inches more wide then the block of ice itself.

Looking Beyond: What do you think has happened? What’s the science?
What questions came up during the experimentation?
I wanted to know how much more gas there was in the dry ice than there was solid.
Did you do any further investigation into the science behind things?
Yes, I learned the phases of matter and learned about the molecules inside gas. Inside of Gas the molecules are not tightly packed and there not a certain shape therefore they can freely move around. It's kind of like a rubber ball in a empty room it just bounces off the wall and continues to do so.
Looking inward: Humans doing science - Lab Practice
Did you get desirable results?
Yes, I got to answer the question my group and I established at the beginning of the experiment.
What did you think you did that contributed to desirable results?
I asked those around me for help and exercised my resources which were useful. They really helped me be able to answer the question.
How do you think you performed in this activity?
I think I performed well. I did the experiment, answered the question, cleaned up and established team work through all of it.
Looking outward: Collaboration and Impact
Who did you work with?
I worked with Kim, Miles, Max and Marcus during this experiment.
How do you think your group performed?
I think we performed good. We really enjoyed the experiment and we all really liked messing with the dry ice. We played "Hot Potato" with it!
What did you contribute to the group?
I helped handle the balloon and measure the circumferences, take pictures and I helped clean up.
Looking Forward: What next?
If you could do this again, what would you change to get better results?
I would most likely use a different ruler because I feel like the ruler we used didn't really round to the balloon very well.
If you were organizing a group for the next lab activity, who would you choose to work with again?
Yes! We really work together good and help each other as much as possible without one of us doing all the work.
Do you see any way to continue this experiment? Would you want to?
There are many ways you can play with dry ice, so I think you can definitely continue on with this experiment and yes.
Takeaways:
What skills, techniques, or pieces or wisdom did you get from this activity?
I learned how to handle dry ice without freezing my cells so much that I end up with frostbite.
