Gears
and Farms
May 13, 2011
The class built and used Crimping Machines to makes paper "hay" for food for their animals.
The gears are placed so that they mesh together.
Smaller sized driver gears made the machine turn easier.
Then they started setting up the farms.
Chickens lay eggs. Chicks hatch from the eggs.
They made many different parts of the farms.
Their butterflies are beginning to hatch!
