I assembled these experiment-sets with gears. The wooden parts where cut at Fablab Leuven out of 6mm MDF. With the basic box you children can experiment with the gears, counting turns and discover gear-ratio.
In the second box they can make more complexe gear systems. They can always connect the motor, to see how everything turns, speeds up or slows down due to the different gears.
The only thing you have to do is glue the wooden parts together. I got the gears and axes by Opitec.be

Lasercut, 6 mm, MDF, glue together!
Step 2: Levers and Linkages
This is a next level of experiments, using the gearbox.
You can think of all sorts of moving systems to build. Connect the motor and see how everything moves.
Step 3: Examples
Some videos of moving systems I built with the gearbox.
