Static electricity Magnetism and electricity ~ Activity 3 Objective • explore the effects of static electricity Working scientifically • Questioning • Observing • Predicting • Investigating and experimenting • Recording and communicating Designing and making • Exploring Background information Electricity is always trying to move from one thing to another. If it cannot move for some reason, it is called static electricity. There are several ways that you can create static electricity, and see its effects. Note: These experiments are most successful if they are done on a dry day. Before the lesson Materials needed • Plastic pens, plastic combs, cloth, access to a wet area with tap, wool or woollen jumper or woollen scarf, balloons, paper, scissors, two magnets, nylon thread, sticky tape. Preparation Set up three stations with materials. Station 1: pens, cloth, small squares of paper. Station 2: combs, cloth, tap, sponges to clean up mess. Station 3: blown-up balloons, wool or woollen jumper. The lesson Stimulus • Ask the pupils if they have ever ‘zapped’ anyone by accident. Where has this happened? What shoes were they wearing? What covering did the floor have? (Usually rubbing rubber shoes along a carpet will create static electricity. Some pupils may suggest getting in and out of a car as well.) What to do • Organise the pupils into groups. Pupils go to each station and use the materials available to test if they can create electricity. • Pupils move to the next station and so on. • Pupils record their findings on the worksheet. • Explain to the class that electricity is always trying to move from one thing to another. When it cannot move for some reason, it is called static electricity. • Either in groups or as a whole-class demonstration, follow the steps in Question 2. Note: The balloons should be hanging at the same height. Tie the balloons 2.5 centimetres apart. • Rub the balloons together with a woollen scarf or jumper. What happens? Pupils draw the results on the worksheet. After the lesson Viewing Sample Answers 1. (a) The pieces of paper are attracted to the pen. (b) The stream of water moves towards the comb. (c) The person’s hair lifts towards the balloon. 2. (a) The balloons pull apart. (b) Teacher check Additional activities • Give the pupils a table for them to place in their books. The pupils record whenever they are affected by static electricity. They describe the events and the materials involved. Display ideas • If available, use a digital camera to take photographs of the pupils completing the experiments. Display the photographs under the heading ‘Static electricity’. 66 <strong>PR</strong>IMARY SCIENCE ~ Prim-Ed Publishing ~ www.prim-ed.com
Magnetism and electricity ~ Activity 3 Static electricity Try each of the experiments below and record what happens. (a) A pen is rubbed on a piece of cloth and then brought near a small piece of paper. (b) A comb is rubbed on a piece of cloth and then placed near a thin stream of water from a tap. Balloon experiment Viewing Sample • When we place two ends of a magnet together, they either join together or they pull apart. Try it! • Blow up two balloons. • Tie them to a string and attach them to a door frame with tape. (ask for help!) • Rub both balloons with wool. (a) What happens? The balloons … (c) A balloon is rubbed on a woollen jumper and placed near a person’s head. (b) Draw and label what happened. push together pull apart www.prim-ed.com ~ <strong>PR</strong>IMARY SCIENCE ~ Prim-Ed Publishing 67
