Demonstrate how the frictional force on an object depends on the surface, not mass.

This box changes resistances in a laboratory circuit.

Students create and observe waves and their properties.

High power and versatility.

Cold and warm pack therapy used by physical therapists, hospitals, and physicians as a therapeutic compress to treat areas of pain and inflammation.

Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analog voltage display. Unit poles can be connected to protected earth, but it is not center tapped.

Investigate the deflection of electrons.

To Accompany Your Tuning Fork!

These large alloy tuning forks are designed to demonstrate resonance, beat frequency, and sympathetic vibration.

The High rpm Steam Engine features an electrically-heated horizontal boiler.

Determine and investigate the current and voltage on a Lecher line.

Boomwackers are brighly colored plastic tubes tuned by length to musical notes.

Appropriate for grades 6 to 12 Brings the First Law of Thermodynamics to life! This pair of precision-machined, chrome-plated steel balls is actually a hands-on demonstration in energy transformation. By striking the balls together, you will create enough heat at the point of contact to burn a hole in a sheet of paper.

Flash lamp bulbs perfect for simple circuit activities.

Ideal tool for studying and observing the basic concepts of a relay.

Durable solenoid for induction experiments.
