Question: Can You Make a Battery Out of a Potato?
Summary: In this experiment, a potato is used to create an electrochemical battery, in which chemical energy is converted to electrical energy through spontaneous electron transfer. The energy created is enough to power a digital clock.
2 Medium Potatoes
2 Cans of Soda
2 Small Grapefruit
Pen and Paper for Taking Notes
- Follow the instructions included with the kit to set up the experiment. Place the potatoes in the two receptacles and observe the effect when connected as instructed.
- Repeat the set-up process using the 2 cans of soda, the 2 oranges and the 2 grapefruit. Observe and record the effect when using these different items as a buffer during the electron transfer.
- Record a hypothesis about what is happening during this experiment.
