Make a light bulb shine using a lemon as a battery
RN: 10100801 - ELECTRICITY & MAGNETISM > ELECTRICAL CURRENT
3 & 4
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]
- COPPER STRIP
- ZINC STRIP
- INSULATED WIRE
- WIRE PLIERS
- 0.2 VOLT LED
HOW TO PROCEED [PROCEDURE]
- 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.
- Then, ask an adult to help you strip clean the plastic covering of the ends of two 300mm long insulated wires, using wire pliers.
