INTRODUCTION [METHOD]

Batteries works because of the energy released by a chemical reaction which is then changed into electrical energy or 'current'. Electrical current is caused by the movement of electrons through a complete circuit and can be used to light a flashlight, sound a bell, turn a motor and many other useful applications.

In this science experiment we will learn more about batteries by making our own battery out of fruit to light a light bulb!

STUFF YOU NEED [MATERIALS]

  • LEMON
  • COPPER STRIP
  • ZINC STRIP
  • INSULATED WIRE
  • WIRE PLIERS
  • NAIL
  • 0.2 VOLT LED

HOW TO PROCEED [PROCEDURE]

Electricity & magnetism science project - Electrical current
  1. Obtain a copper and zinc strip of about 10 x 50mm each from your local hardware store. Ask your parents or an adult to use a hammer and a nail to punch a hole on each end of both metal strips.
  2. Then, ask an adult to help you strip clean the plastic covering of the ends of two 300mm long insulated wires, using wire pliers.
