Get two baskets and go around the house finding objects to test. Place those you guess will float in one basket, and those you think will sink in another. Then it’s off to the laundry tub or bath tub to see if you are right. You could keep track of each and make a chart. You may want to talk about the different attributes that determine float or sink.
