Inch Worm, Inch Worm


A 6th grader and 7th grader worked together in each group.

The inch worms travel in different directions with the pawls in different positions.
Forward, back, and goes no where.

The prototype had two worm gears and small bushings.
However the Motorized Simple Machines Set has one worm gear and only large bushings.
At right is a solution.


Inching along.
