Materials
Balsa wood
Gears
4 tires
Straw
Scissors
2 metal bars
Engine
Solar panel
4 screws
I connected the screws onto the wood.I attached and slid the bars onto the screws and measured the straw to keep the tires in place.Then I connected the tires,putting the gear on the right tire as opposed to the left.I also attached the smaller tires in the front.I put the gear on the engine and placed it with the bigger gear on the tire.I connected the red wire and black wire from the solar powered to the engine on the car.
