Gear Train Model

Three toothed wheels demonstrate the power of gears in motion, direction, and speed. Turn the knob on one wheel and all three move—and the middle one goes in the opposite direction (a great point of interest!).

This big interactive model introduces children to the working of a simple machine. Handcrafted of wood, durable enough for classroom use, with a light coat of varnish. 15" x 6".
