Activity
Electric Lemon
This activity demonstrates how batteries generate electricity.
Materials:
 Metal paper clip
 Lemon
 Length of copper wire
Directions: Have your child straighten the paper clip and insert one end
into the lemon. Remove any insulation from both ends of the copper
wire and insert one end into the lemon. Hold the exposed ends of the
paper clip and the wire and touch both of them to your tongue at the
same time. You'll feel a tingling sensation caused by electricity. How
does this work? You've created an electric battery. A battery needs
two kinds of metal plus an acid. The paper clip and wire provide the
metals, and the lemon provides citric acid. Water conducts electricity,
so your wet tongue completes the electric circuit when you touch the
wires to it.
