Floating and Sinking Experiment Worksheet

Science experiments lesson 1: Floating and sinking · Set 353 · 40 questions

What you do (Float or sink?): 1. Fill a tub with water on a towel, with an adult nearby. 2. Guess “float” or “sink” for each object and write it in a table. 3. Gently place each object on the water and write what happens. 4. Press the sinking clay into a boat shape and try again; wipe up spills.
