Electric Groceries


This week 4AB looked at the history of the battery, or the electric cell as we should call it, and it’s inventor, Alessandro Volta. We then investigated making our own cells from coins, zinc nails and everyday shopping items including lemons, potatoes, oranges and vinegar using a voltmeter to measure the flow of electricity. Even soil could be used to power a small LED although we’re not sure we’ll be able to power the school by connecting it to the school field.
