Note: Each picture can be saved and printed out full page size to be close to real size.
Simple motorized Machine set can be used to study gearing down.
Make a sign rotate once - taking the longest time.
Can you make it take more than eight minutes for one rotation?
Try the opposite of gearing up.
A simple car can use some kind of pivot wheel in the front
and gearing down with 8 tooth meshing 24 tooth gear.
A tread car can be made much in the same manner as the 24 tooth to 24 tooth gearing for
the eLab cars. Link to instructions
Try connecting Duplo Early Simple Machine and Team Challenge set.
Make crimped paper by running strips through between the messed gears.
Try both Duplo and LEGO gears.
Use the interesting paper for hats, "hair", bracelets, or beam constructions.

The extra bumper helps if the bump is directly in front.
