Fruit Batteries!

September 17, 2015

Last week in science, one of the children asked where the electricity in a battery comes from. We thought we would investigate this today, by making our own batteries out of fruit!

 

We found out that when placed in an acid, copper gains electrons and zinc loses electrons. This generates a flow of electrons around the circuit. The acid we used came from inside a lemon, but this is the same process that happens in a battery.

 

We had great fun, here are some of our photos!

 

 This group made nearly 3 volts of electricity from 3 lemons!

 

 

 The LED lit up, although very dimly!

 

 

Apples and other fruits can be used as batteries too!
