Background information<br />

Electricity is always trying to move<br />

from one thing to another. If it cannot<br />

move for some reason, it is called<br />

static electricity. There are several<br />

ways that you can create static<br />

electricity, and see its effects.<br />

Note: These experiments are most<br />

successful if they are done on a dry<br />

day.<br />

Before the lesson<br />

Materials needed<br />

• Plastic pens, plastic combs, cloth, access to a wet area with tap, wool or woollen<br />

jumper or woollen scarf, balloons, paper, scissors, two magnets, nylon thread,<br />

sticky tape.<br />

Preparation<br />

Set up three stations with materials.<br />

Station 1: pens, cloth, small squares of paper.<br />

Station 2: combs, cloth, tap, sponges to clean up mess.<br />

Station 3: blown-up balloons, wool or woollen jumper.<br />

The lesson<br />

Stimulus<br />

• Ask the pupils if they have ever ‘zapped’ anyone by accident. Where has this<br />

happened? What shoes were they wearing? What covering did the floor have?<br />

(Usually rubbing rubber shoes along a carpet will create static electricity. Some<br />

pupils may suggest getting in and out of a car as well.)<br />

What to do<br />

• Organise the pupils into groups. Pupils go to each station and use the materials<br />

available to test if they can create electricity.<br />

• Pupils move to the next station and so on.<br />

• Pupils record their findings on the worksheet.<br />

• Explain to the class that electricity is always trying to move from one thing to<br />

another. When it cannot move for some reason, it is called static electricity.<br />

• Either in groups or as a whole-class demonstration, follow the steps in Question<br />

2.<br />

Note: The balloons should be hanging at the same height. Tie the balloons 2.5<br />

centimetres apart.<br />

• Rub the balloons together with a woollen scarf or jumper. What happens?<br />

Pupils draw the results on the worksheet.<br />

After the lesson<br />

Viewing Sample<br />

Answers<br />

1. (a) The pieces of paper are attracted to the pen.<br />

(b) The stream of water moves towards the comb.<br />

(c) The person’s hair lifts towards the balloon.<br />

2. (a) The balloons pull apart.<br />

(b) Teacher check<br />

Additional activities<br />

• Give the pupils a table for them to place in their books. The pupils record<br />

whenever they are affected by static electricity. They describe the events and<br />

the materials involved.<br />

Display ideas<br />

• If available, use a digital camera to take photographs of the pupils completing the<br />

experiments. Display the photographs under the heading ‘Static electricity’.<br />
