"gel box"

This box changes resistances in a laboratory circuit.

An advanced laser ray box that clearly demonstrates the optical axis.

This laser ray box uses cylindrical LED lenses to focus the beam.

Most comprehensive classroom solution. Countless experiments, so many scientific principles at work and plenty of space for creativity.

Perfect compliment for a ray box.

This kit is very useful for reflection, refraction, and color mixing experiments.

Multiple value resistances with 4mm sockets

Ideal for simulating various electrical values.

The Resistance Substitution Apparatus is convenient for general-purpose resistance work.

Add some student imagination and easily gathered items and students can start investigating pulleys and gears.
