"3B torso model"

Demonstrate how electric coils can be used to power a bell.

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.

Clearly Observe Inner Workings

Allow students to investigate the advantage behind different gear ratios.

Coulombmeter for measuring the flow of current when storing energy in a rechargeable battery.

Basic apparatus for providing contact, power supply and support to a germanium crystal on a circuit board in experiments on the Hall effect or on conductivity. Includes an integrated, adjustable constant current source to provide the current through the sample, a measuring amplifier with offset compensation for Hall voltages and heating to raise the crystal to as high as 170 °C, also featuring temperature regulation and a switchable display showing Hall voltage, sample current, sample voltage or temperature.

With the Atomic Structure Apparatus, a large manipulative helps students visualize atomic structure.

This wooden pendulum has a strong and sturdy construction ideal for classroom use.

Assortment of components for basic experiments in the area of electronics using a component plug-in board.
