P6R turned scientists today, learning how to turn a potato into a battery. We harnessed the chemical power of the potato (the juice in the potato acted as the electrolyte) using washers and pennies as our electrodes. We used crocodile leads to connect the electrodes of different potatoes and to connect the electrodes to the multimeter. We could measure the electrical current in our circuit using the multimeter.
We experimented to see if we could create a higher current by using more potatoes and to see if different vegetables and fruit also worked.
During our Climate Action work we have learnt that the overuse of fossil fuels is a big factor in contributing to climate change and scientists are working hard to discover more sustainable sources of energy – like the potato!
