This week we learned about gravity. The first day we tried to throw popcorn to each other from several paces away. We found out we had to get closer together to get it to our partner. We discovered gravity was pulling the popcorn down.
We read 2 different books about gravity.
We also watched The Magic School Bus: Gains Weight! In this episode Phoebe is trying to slam dunk a basketball but gravity is affecting her! Mrs. Frizzle conducts a lesson on gravity.
We made predictions about whether or not we thought objects, when dropped from the same height, would hit the ground at the same time. We discussed whether size and weight made a difference. Then we experimented and tested our predictions using balls.
We found out that objects when dropped from the same height will hit the ground at the same time if nothing is affecting them (ie: air).
Our last experiment testing gravity was with paper airplanes. We folded airplanes to see how gravity would affect them when we flew them. We talked about how real airplanes have engines that keep them in the air and work against gravity.
