Simulate ocean acidification by introducing carbon dioxide into water and measuring pH over time.

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.

This kit explores chemical nomenclature through experimentation.

Functional glass model of steam turbine.

Ideal for studying electricity.

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

Need a tower for your turbine nacelle? This is the same tower that comes in the Basic Wind Experiment Kit and the Advanced Wind Experiment Kit. The wooden tower has a diameter that fits inside 1-inch PVC fittings.

Hess' Law In Action!

Students will not believe their eyes with this activity which exhibits different optical properties.

Simple, Hands On Experiment

Turn everyday objects like bananas into touch pads!

Use the Exact Water-Testing Procedures Used by Health Authorities

These laboratory burners are compact with a powerful and concentrated flame.

Affordable and Rugged Wind Turbine.

Soft iron is a classic example of a readily magnetized material.

Use the PEM Electrolyzer to produce hydrogen and oxygen using only pure water and an external power source. Take your pick of power sources, all available from Horizon: small solar cell, wind turbines, fuel cells, mechanical hand cranks, or batteries. Using the high-tech proton exchange membrane, this tiny electrolyzer will produce hydrogen for use in any classroom or laboratory activities.
