"gel box"

This box changes resistances in a laboratory circuit.

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

Perform many different lessons around reflection, refraction, diffraction, and interference.

High quality and low cost make this ideally suited for junior high or high school students.

Investigating Inductance has never been this easy

This kit on its own allows a student to experiment with series and parallel circuits, switches and solar power and potentially build their own board game that utilizes the led’s and buzzers.

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.

Ideal for simulating various electrical values.

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

Multiple value resistances with 4mm sockets

Set of color filters to be used with ray box

Ideal selection for use with a ray box.

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

Use this ray box on a whiteboard to vividly demonstrate optical principles.
