Students can make lifelike animal skin rubbings, add texture to their drawings of animals, and create an animal skin scrapbook.

By playing this fun game, students will better understand the intricacies of the rock cycle, including the formation and breakdown of rocks and the processes by which one type of rock becomes another.

Bacteria Make Up Much of the Composition of the Soil

Recreate the spectacular sight of an erupting volcano with this kit, developed by a Smithsonian Volcanologist.

The Optical Voice Link Kit is the ideal introduction for those students first learning about the marvels, mysteries and science of light transmission through optical fiber.
Students will be fascinated by hearing their own voices, after it has been converted into light and then coupled into, through and out of an optical fiber. This kit is suitable for science projects, home projects, short audio fiber optic curriculums for schools, and inexpensive classroom demonstrations.
No prior fiber optics experience, special tools or training are needed for students to be able to build, use and enjoy the multiple applications of this kit.

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.

Power three different solar vehicles — a solar speed boat, an air boat, and a surface submarine — using only the power of the sun. Build three vessels out of your recycled plastic beverage bottles then power them with the sun using the included 1/2 watt, waterproof solar panel. You can build a solar speed boat, an air boat, and a surface submarine. No batteries required.

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.
