Add a regular bulb as your light source for optical benches.

Use this durable push-button switch in battery circuits. Includes: mounting screws.

A steel cube, an aluminum cube and a rectangular aluminum slab have each been painted to conceal the identity of the metal. The steel and aluminum cubes have equal volume while the aluminum slab has greater volume. One plastic metric ruler is included with this set. For use with IPS textbook. Set of three.

WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.

Rectangular blocks in a variety of sizes and are designed for use as an index of refraction plate.

Demonstrate refracrion and internal reflection.

Investigate and experiment with 7 functioning Wheel & Axle and Inclined Plane models designed to demonstrate science and technology concepts.

Students can determine, through investigation, if the machine multiplies the force it applies to the resistance (load), if the machine changes the direction of the force they apply, and more.

This belt-driven generator may be used with our Steam Engine (63030-00 ). Operating at approximately 1500 rpm, the generator will produce enough electricity to light the included 3.8 volt bulb. The unit is mounted on a metal base (7.6×11.4 cm) and has a V-grooved pulley for the drive belt.

Demonstrate the Stirling Design External Combustion Engine with our 18×11 cm working model. The Stirling engine currently is being re-examined as a practical source of power because of its adaptability to almost any fuel. First produced in the 1800’s as a non-electric fan and an automatic hot air water pump, the engine soon became obsolete due to its lack of sufficient power when compared to the newly developed combustion engine. Any fuel can be used with our model, but denatured alcohol is suggested for clean operation.

K'NEX Education Intro to Simple Machines: Wheels and Axles and Inclined Planes is designed to introduce students to the scientific concepts associated with two types of Simple Machines: wheels and axles and inclined planes.

This Equal Mass Density Set is for specific gravity and density determinations.
