Electricity is a form of energy that can give things the ability to move and work. Electricity makes the following to do work or move: bulbs, toys, machines, cars, television etc.
A plastic comb (or a glass rod or a plastic rod), pupils with dry hair, a piece of dry fur or silk, a desk, light paper, e.g. high-quality toilet paper or filter paper, your science notebook, biro.
- Tear the toilet paper (or filter paper) into many small pieces and spread them on a desk.
- Use the plastic comb to comb your dry hair a few times and quickly place it above the pieces of paper on the desk.
- Write your observations in your science notebook. Did you see the small pieces of paper jumping up to hang onto the comb? This may surprise you. But the Greeks also performed this type of activity about 2 600 years ago. They rubbed a material called amber with fur, and it attracted small pieces of paper just as your comb did. Something must be on the comb or the amber that attracts the pieces of paper.
