Can A Lemon Make Electricity Kitchen Science Experiment
In this fun and easy science experiment, we are going to head to the kitchen and learn if a lemon can make electricity.
Materials:
- Lemon
- Two pieces of copper wire
- Knife
- Large paper clip
- Galvanometer
Instructions:
- Roll and squeeze the lemon to loosen the pulp inside.
- Have an adult use the knife to cut two small slits in the lemon about one inch apart.
- Wrap on end of a piece if the copper wire around the paper clip. You may have to remove some of the insulation to expose the bare copper wire.
- Push the paper clip into one of the slits in the lemon.
- Now take the other piece of copper wire and insert a bare end of the wire into the other slit in the lemon.
- Attach the free ends of the two wires to the terminals on the galvanometer.
- Watch the meter to see if the needle moves.

How it Works:
The lemon contains citric acid which acts as an electrolyte. An electrolyte is a solution that conducts electricity. This citric acid also reacts with the paperclip as loosens electrons. These electrons move through the electrolyte toward the copper wire as an electric current that can be detected by the galvanometer.
Make This A Science Project:
Substitute the paperclip with nails, screws, or other small metal items. Test different fruits and vegetables to see if an electric current can be detected. Test the lemon at different temperatures to see if it effects the reading on the galvanometer.
