1. Take a polyethylene plastic (the same plastic that you use in covering your
notebooks) and place it flat on a clean table top, then take a piece of newspaper,
crumple it and rub it once or twice on the plastic sheet. Next hold it and lift it up
briskly. Pass the plastic sheet near your arms.
What did you feel?
2. Place the same charged plastic near your ears. What did you feel?
3. Charge the plastic sheet once more and place it against a wall or against a flat
vertical surface like the blackboard or the sides of a table. What did you observe?
4. Charge the plastic once more and place near the hair of your classmate. What
happened? Why?
5. This time you need to work with a classmate near you. You may work by two's.
Charge your plastic sheets in the usual manner. Holding only the tip of the
corner of the plastic, bring your plastic sheets near the plastic sheets of your
classmates.
