Following on from our electrical circuit knowledge we use to construct our electric cars, a high school science teacher visited us today to teach us about batteries.  However, these were not the normal sort of batteries you would think but fruit batteries.

Using a zinc and copper nail with the acid contained in the fruit, we were able to create a flow of electricity that we measure using a voltmeter.

We then carried out an experiment to find out which fruit provide d the biggest flow of electricity.

By recording the reading on the voltmeter for different fruit, we determined that apples supplied the greatest flow of electricity through our circuit.
