These Optical Refraction Components are made from imported optical glass or acrylic with optically worked surfaces.

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.

Demonstrate how polarizing filters affect light.

Classical experiment for studying optics on a budget.

This lamp holder is suitable for miniature base lamps.

Economical switch for circuit experiments

Dramtically demonstrate the power of atmospheric pressure

This TeacherGeek Mini Hub is designed to slide directly on a motor shaft. It is comprised of two parts that are held together with a single screw. This allows you to secure 2, 3 or 6 turbine blades. When the hub is mounted on the motor shaft and driven by the wind, electricity is generated.

Extra motors used in our popular Catch the Bug Activity.

Make students learn when pigs fly.
