Level 1

Draw a simple circuit using a lemon, copper penny, steel paper clip, coated copper wire and a red LED, and explain (using words, pictures, and symbols) why the red LED lights up when the circuit is closed.

Level 2

An average size lemon is equivalent to (about the same as) a ½ volt battery. Show how you could use additional lemons in the circuit to make the red LED shine brighter than with just one lemon. Explain how this arrangement makes the LED shine brighter.

Level 3

You are out of lemons but still want to make the red LED shine brighter. You have the materials listed in the Additional Materials data table (Insert Materials and Conductivity data table here) to work with. Which materials should you use for the electrodes? Why do you say so?
