Scientist of the Week #3

On Nov. 20 we had our third scientist of the week presentation. This cute scientist did a great job! We had a little trouble because the trip from the freezer, where the bottle and air inside was getting cold, to the classroom was a little too long. So the balloon didn't expand like it should have. Our scientist knew the trick to get the air to warm up was to put it under her arm. So she just squeezed a little extra, and the balloon inflated!



To see if this experiment would really work, I ran and put the bottle back in the freezer. We wrote in our science experiment booklet and drew a picture. Just before recess, we all walked to the faculty room. The scientist and I went to the freezer. We took out the bottle and immediately put the balloon over the top. And it did start to inflate a little as we warmed up the bottle in our hands. So this experiment didn't turn out perfectly, but our scientist wasn't discouraged. She was so positive. She did a great job and we all learned that sometimes you have to try things several times before they turn out. You might want to try this one at home. I wonder if a glass bottle might work better. ?? Try it and see!
