Build a Penny Lab
1) What were the metals involved in your battery?
Zinc side of penny/copper side, aluminum foil and zinc washers.
2) If your LED requires 1.5 volts to light up, how many volts did each cell of your battery provide?
It took between 6 and 7 layers to power the small LED, so it was about 0.214 volts per cell.
3) How is energy being converted to electricity in this battery?
The metals react with the acid which creates electricity.
4) What is a voltaic pile? How is it related to the battery you just built?
When you combine metals with electricity which creates energy. The metals we used in our battery were copper and zinc and our electrolyte was vinegar.
5) What is an electrolyte?
A liquid or gel that contains ions and can be decomposed by electrolysis, and electricity can pass through it.
6) How did you know which end of the battery was positive, and which end was negative?
The longer leg of the LED is positive, and the shorter leg was negative. We also tested it to see.
7) Determine at least two other potential uses for your battery other than lightening an LED. What else could your battery power?
Some clocks and radios.
Zinc side of penny/copper side, aluminum foil and zinc washers.
