Static Electricity Experiment Worksheet

Science experiments lesson 21: Static electricity: comb and paper bits · Set 305 · 40 questions

What you do (Rub and charge): 1. Tear a sheet of paper into tiny bits on a table. 2. Comb dry, clean hair quickly 10 times. 3. Hold the comb just above the paper bits and watch. 4. Try again with 20 combs, and count the bits each time.
