Fruit Battery
Written by Dolphin Class :)
We were trying to find out which fruit had the most voltage to power an LED.
Amazingly, you can turn fruit into a battery! We put a 1p coin in one side of the fruit because it was made of copper. Then, we put a nail on the opposite side of the fruit because it was made from zinc. These two metals acted as electrodes. The fruit juice was an electrolyte. This made a cell.
We joined the cell to an LED (light emitting diode) to see if it lit up. One cell didn't have enough voltage to make the LED light up so we added another. The grapefruit, orange, lemon and lime dimly lit the LED with two cells. We think this is because it doesn't matter which fruit you use or how big it is, its still the same type of juice inside.
After, we connected all the cells together to make a larger series circuit with 8 cells! The LED was much brighter. It was brighter because there were more cells and therefore more voltage.
The History of Electricity
We ordered electrical invention based on when they were first invented.
Did you know the first hovercraft was invented in 1955?
