Hey see here __!!!!

to show that electrons and protons attract each other.
Students can see evidence of the charges of protons and electrons by doing an activity with static electricity.

Note: When two materials are rubbed together in a static electricity activity, one material tends to lose electrons while the other material tends to gain electron. In this activity, human skin tends to lose electrons while the plastic bag, made of polyethylene, tends to gain electrons.

Question to investigate
What makes objects attract or repel each other?

Materials for each group
Plastic grocery bag
Scissors
Procedure, part 1
Charged plastic and charged skin
Cut 2 strips from a plastic grocery bag so that each is about 2–4 cm wide and about 20 cm long.
Hold the plastic strip firmly at one end. Then grasp the plastic strip between the thumb and fingers of your other hand as shown.

A student holds a long strip of plastic between her thumb and index figers.
Quickly pull your top hand up so that the plastic strip runs through your fingers. Do this three or four times.
Allow the strip to hang down. Then bring your other hand near it.
Write “attract” or “repel” in the chart on the activity sheet to describe what happened.
Expected results
The plastic will be attracted to your hand and move toward it. Students may notice that the plastic is also attracted to their arms and sleeves. Let students know that later in this lesson they will investigate why the plastic strip is also attracted to surfaces that have not been charged (neutral).

A student holds a long strip of plastic in one hand with his other hand nearby.
Note: If students find that their plastic strip does not move toward their hand, it must not have been charged well enough. Have them try charging their plastic strip by holding it down on their pants or shirt and then quickly pulling it with the other hand. Then they should test to see if the plastic is attracted to their clothes. If not, students should try charging the plastic again.
