"physics kits"

Perfect for putting the 'A' in STEAM, why mess with wires when you can use conductive tape?

The rolling friction car kit provides four cars for exploration into the force of friction. Each car provides a set of different material wheels (wood, fabric, soft rubber, soft silicone) with a different coefficient of friction. By setting the cars in motion with equivalent velocities, one can qualitatively demonstrate the frictional properties of rolling without slipping.

The simple Atwood Pulley Machine features two pulleys connected to a sturdy rod.
