SCIENCE FAIR

Trey was in the 5th grade science fair at GV Elementary. This is where the 5th grade students strut their stuff and come out of the closet, showing they do have a brain. Trey created a lemon powered fan. (Really? Lemons can create power from the citrus? Wow. I didn't know that...)

What is it?
*Trey: A lemon powered battery.
How does it work?
*Trey: All the acids go together into an electrical system and it sends all the electricity through the wire, to the generator, and spins a piece of plastic with string.

How does the acid in the lemon create electricity?
*Trey: 1 of the acids in the lemon are zinc. Zinc is one of the main things in batteries. with all the zinc in the lemon, the nail and the penny transfer all the electricity to the wire. The wire sends it to the generator.

In conclusion, could president Obama use lemons to run vehicles?
*Trey: No. 1 lemon creates 3/4 of a volt. You would need 125 lemons to create 200 volts. A car battery holds 12 volts. You would need 6 lemons according to the calculations, but it doesn't make sense. Would it be possible??

Other science experiments included dissolveing egg shells, baking soda volcano (which Trey helped create also), decomposing ...(as seen below)

And here is the baking soda volcano.

The science fair was fun.
What was your favorite part?
Trey: That we got to share our inventions.
