Today the kiddos had a blast during "Pumpkin Science." I purchased a medium sized pie pumpkin for the class to use and I let all of the students hold it to see how heavy it was. I then asked them to predict whether the pumpkin would sink or float in a tub of water. All but two of the students said it would sink... either because it was heavy or because it was big. Needless to say, they were amazed when TAH-DAH! The pumpkin FLOATED! I asked them why it floated and they said that maybe it wasn't heavy enough to sink, but that was quickly debunked when I showed them how a tiny yellow crayon sunk straight to the bottom. The experiment blew their first grade minds! It's nice to really wow your students with something so simple :)
