Looking Back:
How did your experiment turn out?
We had a block of dry ice and passed it around the table. Our goal was to find out a way to measure the dry ice when it was a solid and measure it when it was a gas and see how different the mass was. We did this by measuring the mass when it was a solid, then making the solid into a gas by putting it in a balloon to capture the gas.
Did it work?
Yes, we measure the circumference of the dry ice block, it was about half an inch. Then we put the dry ice cube into a balloon and waited for it to sublimate (solid to gas). When it was done we measured the circumference of the balloon and it was 8 inches. The gas was seven and a half inches more wide then the block of ice itself.

Looking Beyond:
What questions came up during the experimentation?
Why does it turn from a solid directly to a gas? Why skip liquid form?
Did you do any further investigation into the science behind things?
Yes, I learned that it turns from a solid to a gas because there wasn't enough pressure in the room to make it become a liquid, so instead it goes through sublimation.
Looking inward:
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 tried to explain why the dry ice goes from a solid directly to a gas through sublimation.
How do you think you performed in this activity?
I think I performed well. I did the experiment, answered the questions, and cleaned up.
Looking outward:
Who did you work with?
I worked with Kim, Ashleigh, Max and Marcus.
How do you think your group performed?
I think we performed well. We really enjoyed the experiment and we all really liked playing with the dry ice.
What did you contribute to the group?
I helped handle the balloon and measure the circumferences, explain the science, and I helped clean up.
Looking Forward:
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 work together 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 experiment with dry ice, so I think you can definitely continue on with this experiment.
Takeaways:
What skills, techniques, or pieces or wisdom did you get from this activity?
I learned about sublimation and about the the freezing, melting, vaporizing, etc points of dry ice.
