Does Soap Float? is a perfect experiment for the teacher to demonstrate in order to practice the scientific method. You will need 4 bars of soap (one of them being Ivory). Fill out the first 2 columns of the Does Soap Float? form together. Have students make their own hypothesis for each type of soap. Then, in a bucket of water slowly place each bar of soap. USE IVORY LAST, because it will float. Then, finish the form with observations you made. Have students complete the Science Experiment Form on their own.
