This advanced ripple tank comes complete with all accessories needed for wave investigations.

Oersted's Apparatus demonstrates the magnetic field created by a current.

Enhance your electroscope with these fine gold leaves.

Show students how light reflects inside an acrylic pipe.

The Bottle Rocket Launcher uses the power of compressed air and water for liftoff.

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.

Economical set for studying friction.

This extra large electroscope is ideal for classroom demonstrations of electrostatic principles. A lightweight metal vane is used as a pointer in the electroscope. This lightweight metal blade deflects when the electroscope plate is charged. A transparent scale is provided to measure the angle of the deflection. Front glass window slides up to allow insertion of ionizing material in chamber.

Dramtically demonstrate the power of atmospheric pressure

A pair of 100g gliders designed for use with air tracks 470157-654 and 470157-664.

Economical set for teaching the basics of circuits

Beautiful, large, and functional gyroscope for classroom demonstrations.

Visualize the shape of the magnetic field around a magnet.

Recreate the medieval weapon using counterweights.

This kit is used to perform the classic experiment of the 'Monkey and the Hunter'.
