ACTIVITY SHEET I. CHARGING BY FRICTION CHARGING BY FRICTION, INDUCTION AND CONDUCTION what happenin. Rub a rubber balloon with your hair and place the balloon near tiny pieces of paper. Explain Rub a plastic comb with a piece of wool, Explain what happens. GUIDE QUESTIONS 1. How will you describe the electric charge/s of the materials after rubbing? 2. What causes an object to become electrically charged? 3. How will you explain the role of electron transfer in electrostatic charging by rubbing? of why not? 4. Can you easily identify which of the materials will become negatively (positively charged? Why 5. What is the net charge of the two materials after rubbing? Explain I.
