We did a fun little science experiment yesterday with a balloon, soda bottle, and water. Our lesson was about air molecules, and what happens when they heat up and cool down.
We had a pot of hot water and one of cold. The kids took turns moving the bottle back and forth, checking out what would happen. In the hot water the balloon expands, in the cold it quickly shrinks!
Look at you getting all crafty!! What a great experiment!
