How can the effects of electric charges be observed

Electric charge plays an important role in atomic structure. 

Cut out small round pieces of paper using a hole punch, and spread them out on a table. 

Run a plastic comb through your hair. Bring the comb close to the pieces of paper. Record your observations. 

Obtain two 10-cm pieces of tape. Fold a 1 -cm portion of each piece back on itself to form a handle. Stick both pieces of tape firmly to your desktop. Then, quickly pull both pieces off of the desktop and bring them close together so that their nonsticky sides face each other. Record your observations.
