Method or Procedure:
1. Go into a dark room with the light bulb and hair comb.
2. run the comb through your hair around 20 times.
3. Place the comb on the metal end of the light bulb and watch as the filament in the bulb lights up.
Observation: The filament in the bulb glows.
State and explain the science behind the activity (in 100-120 words):
When a comb is rubbed on hair, it gets charged. When this charged comb is attached to the metal ends of a bulb, then due to the flow of electrons a current starts flowing in the circuit which causes the bulb to glow. Regards
