Kids are fascinated with the way things work.
The great blocks of stone that made the pyramids were not lifted into place they were rolled up ramps, or what we now call inclined planes. The inclined plane, one of the simple machines, allows you to raise great weights with small forces. This model lets students experiment with this principle directly, by seeing how much force is needed to pull the cart up the ramp. This wooden model is handcrafted from durable hardwood with smooth-moving parts allowing children to explore the concept of force.
