We made some projects with gears.
The older group made cars.
Get the correct pieces.
Place them exactly right.
Will this car turn easily?
Try out each of them.
They do not look much different
but they are.
One turns easily.
It has separate axles for each wheel.
The ones that go straight but turns poorly has a single axle through
two wheels.
Design a car that can go by wind power.
Ready, set, blow.
