The Collision in Two Dimensions apparatus is a rich source of data for studying conservation of momentum and conservation of kinetic energy in collisions.

What Happens When You Combine All Colors of Light?

This inexpensive device detects and estimates charges.

Instantly transform potential energy into kinetic energy.

A Classic!

Heavy Rubber Pipette Bulbs

This solid socket board holds light bulbs for circuit experiments.

Smooth-running ball-bearing clamp pulley for use with inclined planes, force experiments, or demonstrations of work and machines, this durable, lightweight plastic pulley fastens to surfaces up to 18 mm thick.

This working model hydraulic/pneumatic jack shows how hydraulic or pneumatic systems can multiply forces.

The Moment of Force Apparatus contains everything needed to study principles of mass, levers, moments, forces, and equivalence.

Convenient and autoclavable.

To explore light reflection and refraction properties of concave and convex mirrors, laws of reflection, image formation, the effects of surface curvature on reflection, spherical aberration, etc. Each mirror is securely held on a plastic base. The diameter of each mirror is approximately 95mm.

Tip-free stability for experiments.

Alnico bar magnets are useful for classroom or lab experiments.

Take the classic resonance box to a whole new level.
