• Demonstrates the sun's energy.
• When in sunlight, the vanes rotate at a high rate of speed.
• When in darkness the vanes cease movement altogether
• Shows how solar energy can be converted into motor energy.
• Shows students the bombardment of molecules within a near vacuum.
• Comes with complete sheet cataloging known and unknown factors about energy.
Demonstrates the sun's energy. When in sunlight or artificial light, the vanes rotate at a high rate of speed. When in darkness the vanes cease movement altogether, showing the simple principle of energy from the sun can be converted into motor energy. This device gives your students the benefit of seeing the bombardment of molecules within a near vacuum. Comes with complete sheet cataloging known and unknown factors about energy. Our Radiometer is made from a glass bulb from which much of the air has been removed. Inside the bulb, on a low-friction spindle, is a rotor with 4 vanes. Each vane has one blackened side and one silvered side; one black vane features a white dot in order to count rotations easily.
Used to power portable radios, cassette players, children's toys and other situations where four C, AA or AAA cells are used. Size: 6.375 x 4.5 x 0.375" 11 oz. The F6220 includes a 12 foot cord, DC adapter jacks and jumper cord.

Fun Circuit Building Experiments for Beginners Construct circuits with colorful electric building blocks to learn about electricity and how electronic devices work. With the innovative snap-together blocks in this kit, children eight and up can safely and easily begin experimenting with electronic circuits. These building blocks are specially designed to make learning electronics fun and accessible. Because the blocks are brightly colored and have unique shapes, it is easy to follow the assembly diagrams to construct functional circuits. And because the circuit symbols are printed directly onto the blocks, you can quickly become familiar with the symbols and learn how to read circuit diagrams. The fun building projects include an alternating blinker, a police siren, an ambulance siren, an alarm system, a light detector, a conductivity tester, a rain warning system, a timer, and logic circuits. The electronic components in this kit include capacitors, resistors, transistors, LEDs (light emitting diodes), a phototransistor, a switch, 30 contact blocks, cable blocks, a battery holder, a speaker, and a sound integrated circuit. The 64-page, full-color experiment manual guides you through 70 circuit building experiments with easy-to-follow diagrams. This kit provides kids with the tools and instructions they need to experiment with their own hands and learn firsthand how electronics work.
• Build your own simple solar thermal updraft towers
• Collect the sun’s energy and use it to spin five colorful turbines
• Learn about thermal updrafts and solar thermal energy.
Solar thermal energy refers to the technology of collecting solar energy in the form of heat and making it useful, for example, by converting it into electricity or heating homes. Huge solar thermal towers are being installed in sunny places around the world to convert the sun's heat into electricity via turbines powered by hot air. With this kit, you can build your own simple solar thermal updraft towers to collect the sun's energy and use it to spin colorful turbines. Test the solar turbines in various configurations and compare the results from two different towers. Learn about thermal updrafts and solar thermal energy.
