Task 1: STORING ENERGY IN BATTERIES
This lesson is about batteries. Look around and find as much as you can different types of batteries. There are batteries of various shapes and size. But they all do the same thing – THEY STORE ENERGY.

At times we need to store electrical energy. This is done in batteries where the electrical energy is changed to stored energy. You may find a number of batteries at home…in a car, in a mobile, in a wrist watch, in an emergency lamp, in a television remote control and so on. Follow this video about different types of batteries. You may not understand all the details but it gives a good view of different batteries. ONE UNIT OF BATTERY IS CALLED A CELL. (Note that this has nothing to do with cells found in living things.) A battery is usually made up of two or more cells. Resource 1_BATTERIES show a great variety of batteries. Look at Resource 3_ELECTRICAL SYMBOLS of the previous lesson and find the symbol used for a cell and a battery.

Task 2: MAKING A BATTERY
You may build your own battery. Use the following video. You may look for similar video by looking for lemon batteries on YouTube. You may try other fruits or vegetables instead of lemons.
