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.

Set of seven metal electrodes for electrochemical experiments.

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

The Magnetic Force on a Conductor demo show students how a current-carrying conductor behaves when placed in an external magnetic field.

This large Van de Graff generator uniquely offers alternative drive modes, either hand-cranked or motor driven.

Whiteboard Color Optics are a complete system for investigating color, reflection, and refraction.

The Vernier Arduino Interface Shield plugs directly on top of the Arduino and adds two BTA (analog) and two BTD (digital) sockets. This shield was developed to be used with the SparkFun Arduino RedBoard but will work with the Arduino Uno and other Uno equivalents like the Leonardo. It also works with the Intel Galileo.

Comprehensive Basic Electricity Kit For Building and Studying Circuits.

A comprehensive set designed for safe and repeatable observation of electrostatic field lines using various electrode patterns.

The KidWind Motor Mount Pack holds the motor (generator) in place when affixed to the wind turbine nacelle. The Motor Mount Pack can be used to replace lost parts from a nacelle. It can also be used to mount a nacelle to the tower for a vertical axis wind turbine configuration.

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.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.

The simpleGEN is an easy-to-build AC generator that allows students to explore the basics of electrical generator design. With the simpleGEN, you can demonstrate Faraday’s law, light LEDs, and perform experiments that explore how coils, magnets, and rotation affect electrical generation. With some quick modifications, you will be able to convert your generator to a simple motor and explore additional variables. You can also take your experiments to the next level by converting your simpleGEN into a wind turbine nacelle.

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.

The hub will press fit onto the shaft of many small DC generators; just attach your own blades and begin experimenting with wind power! The hub is designed to allow you to change blade angles and/or interchange blade sets quickly and easily. An improved stainless-steel insert can take a beating in your classroom year after year without failing!

Updated, Compact Zeeman Effect Apparatus uses a high resolution Fabry-Perot interferometer and a USB video camera
