Solar Bag
The world’s largest solar bag—you’ve never seen a solar bag like this one! Our 50-foot- long, 3-foot-diameter black plastic solar bag holds over 350 cubic feet of air. Simply fill with air, tie off the ends, and let the solar energy of the sun heat the air inside the bag. In less than ten minutes, the bag will rise into the sky. The solar bag rises so fast
it must be tethered to hold it down. In less than one class period, density and buoyancy are taught in a very dramatic way. Detailed instructions included.
AP4622 I $22.90
14-in-1 Solar Robot
Build a robot powered by the Sun! Learn how solar energy can turn a small motor. When that motor is connected to other materials, the possibilities are endless. Includes instructions for building 14 different robots. Construct a turtle, crab, boat, beetle and even a zombie! Enough materials to build one robot at a time. Includes an 82-page assembly manual with helpful diagrams.
AP7910 I $39.75
Radiometer
One of the all-time classic solar engines, the Radiometer demonstrates the effect of infra- red radiation with the spinning of its vanes. Just set it in bright light or the Sun, and away it goes. The hows and whys of solar motion are discussed in the accompanying literature.
AP1948 I $16.05
Renewable Energy Set
Explore wind, solar and water energy
with three interchangeable power units mounted to a sturdy plastic base. Monitors can be connected to the base to make sounds, flash lights, turn gears or measure voltage and measure energy produced. High-impact plastic base is 7" x 10" with a maximum height of 20"; monitors are 3" in diameter. Includes 20 feet of clear plastic tubing and a packet with suggested activi- ties and instructions.
AP7819 I $225.95
Mini Solar Panels
Design your own solar energy experiments with these durable, mini solar panels. Encapsulated in plastic cases, they will stand up to repeated student use. Connect to various devices with 6" lead wires. Each panel measures 33⁄4" L x 21⁄2" W. Available in 1.5 (200 mA), 3 (100 mA) and 6 V (50 mA).
