Build your own eco-friendly green energy saltwater car by firstly building the car frame with plastic boards, axels, brackets and wheels. Next build your saltwater energy source (battery) by combining alligator clips, a carbon plate and wire to your motor. Finally add the gears to the motor which rotates the axel. Just add salt water to start your car.
Learn how salt water provides the electrolyte used in a chemical reaction inside a fuel cell. This chemical reaction creates electricity, similar to how a battery creates electricity. This electricity runs a small motor which powers the car as the magnesium loses electrons and the carbon plate receives electrons resulting in electricity being generated.
The main parts in this STEM project combines a mixture of:
- Carbon Plate
- Alligator Clips
- Plastic Frame Parts
