Bob for Apples and Other Bucket Fun
Fill a large container with water and apples and have the kids hunt for them with their mouths just like you did when you were a kid. Once each kid has claimed an apple, play a game of sink or float. Gather household objects that can get wet (a shampoo bottle, a Matchbox car, a soup ladle) and make predictions about whether or not each object will sink or float. When things sink, kids can go in after them and cool off even more.
