Fruit battery
We looked at a few of the many applications of science and technology involving products available from a supermarket. In this experiment we use the acids withn different fruits as a battery. Monitor your results for the different fruits and see what produces the most power.
You will need:
- Different fruit (lemons, potatoes…)
- metal strips
- nails or coins
- LEDs
- crocodile clips (can be bought in DIY/hardware stores)

1
|
Roll the lemon around or give it a good squeeze to get the juices moving. |
|
2
|
Insert a penny into a cut on one side of the lemon. |
|
3
|
Push a galvanized nail into the other side of the lemon. The nail and penny must not touch. |
|
4
|
Attach crocodile clips from the nail and penny to the LED to complete the circuit. |
|
5
|
Use additional pieces of fruit if necessary to light the LED, see how many of each item is needed for success. |
Tips:
- You could also compare different types of metals and see whether any of them are more effective.
