To celebrate the completion of our Science unit on Simple Machines, the class will be working in teams of three to invent a gravity-driven car!
The cars will be made only of recycled or used materials and can be no bigger than an ordinary desk ruler. When the “contest” day comes the cars will be launched down a ramp and we’ll measure how far they go! The class will be challenged to use what they learned about friction, simple machines, etc. to try to make their cars travel far.
Here are some examples of cars made for our first “Great Car Design” contest:
