I made a scale before the group came in for class and they figured out which is heavier - a bear or a pencil.
We went over
and procedures and then they started to build their own projects.
They learned about gears by building a merry go round.
The 4-H news paper came.
Lawn mover uses wheels and axles.
Separate axles makes turning easy.
The funny face and crane use pulleys.
Wheels can be used for roller conveyor with a winch.
Air power - pneumatics
were used for a press
and a lift.
Then it was fun to put projects together.
