Science with Water

We worked with a tub half filled with water tonight. He placed the whistle tube in it and found that it makes music when the ends of the 'U' shape are alternately pulled up and down. Then we learned about buoyancy by using a clear plastic case (it was originally for a pair of his water sandals) that has unequal sides (the opening, from top to bottom), and then the buoyancy of different balls. Cute video of it except he decided that he was going to have to go potty in the middle and he kept holding himself during the video we were shooting.
