The reversible fuel cell combines the functions of an electrolyzer and a fuel cell into ONE device.

Designed to provide a simple, affordable, and nonhazardous method of testing water for nine basic water quality parameters, this kit contains everything a science class needs to test water samples.

The Jolly Logic Altimeter analyzes flight altitude, acceleration, top speed, flight duration, and six other important flight statistics.

This new conductivity bar set features sensitive liquid crystal temperature indicators, which are attached to the front of each of four metal bars.

The Moment of Force Apparatus contains everything needed to study principles of mass, levers, moments, forces, and equivalence.

Closed Case Form Electroscope is enclosed, preventing air currents from affecting the deflection of the leaves.

A must for your optics lab!

For Use With Solar Cell.

The large size of the Newtonian Demonstration makes a big impression and helps explain the theory.

This demo features a cathode beam to explain the electromagnetic nature of electrons.

The Economy Magnet Kit showcases the basics of magnetism.

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.

Present a Wide Variety of Standard Force and Motion Activities.

Educators can conduct a comprehensive array of density experiments with the density/slope class set.

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

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