Make Electricity from fruits
This project is one of the most famous electricity projects that can be performed successfully by most students in the age of 10 to 16. It helps students to learn about producing electrical energy using chemical energy. Since the same method is used to get energy from many fruits and chemicals, this project has many names. Following are some of the other names or titles for this project:

Making electricity from chemicals is based on the same scientific principles on which all modern batteries work. You insert copper and zinc electrodes in an acidic liquid and produce some electricity from the chemical reaction between your electrodes and electrolyte.
| The electricity produced in this way can be displayed with a multi-meter that can show millivolts. It may also be able to produce enough electricity to get light. If you want to run or light up a device you must consider the voltage and current requirements of that device. Picture in the right shows 3 potato batteries connected in series so together they will produce enough voltage to light up a super bright LED type light source. |  |
| 1. Experiment to see which fruits can produce electricity. | 4. Replace electrodes of your kit with other metals such as coins, nails to see which other metals can be used as electrodes. |
| 2. Experiment to see which fruit juices can produce electricity | 5. Test to see if such electrodes can light up a bulb. |
| 3. Experiment to see which other liquids such as detergents and drinks can produce electricity. | 6. If you have access to a multi meter, check to see how many volts electricity is being produced by fruits. |
Material and equipment: Material and equipment that you need for this project are:
- Copper Electrode
- Zinc Electrode
- Multi-meter capable of measuring low voltages
- Flashlight light bulb 1.2 Volts
- Screw Base or socket for light bulb
- Wires
- Alligator clips
- Board for mounting the base and the bulb (optional)
