With the Visible Variable Inertia Set, students see and feel the relationship between mass and radius in rotational dynamics. The set includes 2 identical clear disks each with 8 wells for steel spheres, allowing easy adjustments to the rotational inertia.

The Gyroscope Wheel is an innovative tool for teaching rotational inertia and gyroscopic precession in a safe and engaging way. Its adjustable masses and large-scale demonstrations make it easy for students to experience these complex concepts.

QuickStudy Reference Guides offer an efficient and well-rounded means for storing information in an easily accessible place. This durable Physics Equations & Answers reference guide is laminated for use year-over-year.

The DIY Fuel Cell Science Kit comes with everything needed to split water and use its hydrogen to generate electricity. Incorporate it as a STEM activity into your classroom today!

The Multi Energy Car Science Kit includes everything students need to experiment with sustainable transport solutions. Measure the superior energy density and power of the supercapacitor, compare different kinds of fuel cell technology all of which convert elements into electrical energy: the direct ethanol fuel cell, the salt water fuel cell and PEM fuel cell. Plus, you can demonstrate the power of sunlight with the solar panel and generate electricity with the hand crank.

The Faraday's Law and Lenz's Law Complete Demo Set contains everything needed for a show-stopping electromagnetism demonstration. Use this demo set to explain what happens when the falling magnet disappears into the copper collar. It is not magic—it is physics!

With this easy-connecting kit, students learn the fundamentals of electricity by building various circuits, and then are introduced to the concepts of voltage, resistance, and electrical current. Each of the electrical components is mounted on a durable plastic magnetic base (embedded Neodymium magnets) designed to help keep things organized on a custom magnetic receptive mat that also functions as a dry erase board for tabletop use. Please Note: The Miniature Digital Ammeter and Miniature Digital Voltmeter are not included in this kit.

This Miniature Digital Voltmeter is designed to clip right into your circuit. It comes with alligator clip leads, has a small size and features an elegant design that makes it easy to measure voltage - especially for the novice.
