"3B torso model"

Explore horizontal wind energy with a DIY hands-on turbine model.

This working model hydraulic/pneumatic jack shows how hydraulic or pneumatic systems can multiply forces.

Students measure acceleration due to gravity in this free-fall activity. Video analysis allows modeling of air resistance.

Functional glass model of steam turbine.

For class model building.

Ensure perfect geometric alignment of your balsa fins on any Estes model rocket.

With this kit, the intangible, nanoscopic world becomes accessible with hands-on experiments using both scaled-up models and real nanomaterials.

Explore horizontal wind energy with a DIY hands-on turbine model, now including AC and DC power generation.

The Digital Photogate Free Fall Apparatus retains the precision of older models while eliminating the hassle of setting up heavy steel columns and adjusting spark recorders.

A simpler version of the Advanced Pulley Demonstration Set, this model includes eight single pulleys and two double sheave pulleys in addition to EISCO ball bearing frictionless pulley.

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.

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.

The Solar Thermal Exploration Kit is modeled after a domestic solar water-heating system. Explore variables such as box color, light intensity, tube design, rate of water pumping, and amount of time it takes to heat the water. Learn about what makes a solar water heating system more or less efficient.

This product is a small-sized model unit used for explaining the principle of a planetary gear. By setting the internal sun and pinion gears into motion (input or fixed), you can get the different outputs from acceleration, deceleration and reverse. Comes equipped with a storage case holding 10 Planetary Gear Demonstrators. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimentions: 24L x 14W x 14H cm ; Weight: 3kg

Useful for collision and pendulum experiments.

Compact 7.2 V, 200 mA solar panel is ideal for DIY projects and small devices.
