This is my third experiment and it is about chemical energy. Enjoy!

Objective: To make a battery from lemons to test a property of chemical energy.

Procedure:

1. Connect three lemons together with copper and zinc wires and also screws and pennies.

2. Do not connect the last screw and penny together. Instead, connect to a voltage meter or LED to test voltage.

3. How much voltage do the lemons produce? 

Data:

It works!

Conclusion: We had some problems with this project. We couldn't get the penny in, and the LED needed more power than we thought. Other than that, the experiment went well and we got the answers we wanted.
