What Should You Expect From This Lesson?
By the end of this lesson children can become aware that many things use electricity, distinguish between things that work with electricity and others that do not, identify appliances or machines in the home and outside the home which use electricity to work and learn that electricity can be very dangerous.
How To Carry Out This Lesson At Home:
Resources required:
Work sheet – Electricity
Video clip: How to make your hair stand on end Science Experiment – https://video.link/w/9izjb
Resources: balloon, sweater or t-shirt (or a piece of woollen fabric)
Online games – : http://www.sciencemz.com/electricity-in-the-home/
Engage :
Ask the children to mention some of the things they see around them. Ask them if it is possible to see all the things they mentioned when it is dark. Elicit that a bulb, a torch or a spotlight is needed in order to see in the dark. Ask the students what makes a bulb light and elicit the word ‘electricity’. Encourage the children to point out items in the classroom that use electricity and ask them how they work, for example the light switch, computer or interactive whiteboard. Explain that many items in the classroom, such as the lights and computers, work using electricity. Some of them get their electricity from batteries while others are plugged into the electricity supply.
Emphasize that electricity is not something that we play with and that it can be very dangerous.
Inquire :
Experiment – Produce your own electricity.
Tell children that you are going to conduct an experiment where you will be producing your own electricity by rubbing materials together.
For this experiment you will need:
a balloon
sweater or t-shirt (or a piece of woollen fabric)
someone with long hair (preferably without hair spray or styling product in it)
Click on the link below to view the experiment and afterwards carry out the experiment.

Method:
Inflate the balloon.
Place the balloon over the child’s head to show them that nothing happens.
Rub the balloon back and forth on a sweater or t-shirt. Do this for 5-10 seconds.
Now place the balloon over the child’s head and watch what happens this time!
Explain that in this experiment we produced electricity by rubbing the balloon and the sweater together.
Activity: Electricity at home:
Many things at home need electricity to work. Some items are easy to recognise as they have a wire, a plug and a switch to turn it on or off. Other items, like for example a watch, use batteries in order to work.
Go to: http://www.sciencemz.com/electricity-in-the-home/ and click on all the objects that need electricity to work.
Activity: How electricity can be helpful in our lives
Explain that electricity has many uses in our everyday life. It is used to light up rooms, for fans and domestic appliances like electric cookers, the air conditioner to work. All these provide comfort to people. Imagine what would happen if there was no electrical supply to your house for one week!!!
Click on the following link and match the electrical appliance with the work it does:
Assess and Evaluate:
Electrical or non-electrical
Some objects need electricity to work while others do not use electricity. Click on the link below and place each picture in the correct group.
Give the worksheet to the pupils. Students have to distinguish between things that work with electricity and others that do not.
