We just got done with science fair season and Benjamin chose to do one this year. Here the students aren't made to do one, but can if they choose. He chose electricity more specifically if you can light a bulb using food.
First we chose the food to use.
Then we did some testing. And yes everything produced a current.
Then we made a lemon battery and tried to light a 3.5V LED bulb. Yes, it worked. The first picture is with light and the second is without. Hopefully you can see the difference. It was hard to get a good picture.
