"Wards"

Use this set of nine unknown resistances to work with your Wheatstone bridges.

The durable Wilmshurst Machine is made for years of use.

This box shows Planck's Constant in action.

Students use the St. Louis Demo Motor to research fundamental principles of electric motors and generators.

Teach magnetism, motion, Newton's Laws, and more with this fun ball launcher. Simply align these powerful neodymium magnets on a linear rail and arrange steel balls in a sequence for a truly engaging lesson.

Study the motion and behavior of gas molecules with this intriguing demonstration. An electric motor, running at 4 to 12 V DC, vibrates a small platform inside a transparent tube. This platform then violently vibrates the many small stainless steel balls inside the tube.

The Parallel Plate Capacitor helps students understand the principle of capacitance, its relationship with charge and voltage, its dependence on THE surface area of conductors, and the dielectric medium between two plates.
