Solar Car Assembly KitFor moderately experienced model builders. Using the Solar Car Assembly is a great way to experiment with gear ratios and the angle and intensity of solar light. With three gear ratios, high speed (1.7:1), mid speed (2.2:1), and low speed (3.4:1), you can see the difference gear ratios make under different conditions. The ball-mounted solar panel allows you to angle the panel towards or away from the sun, showing how direct and indirect solar light can affect power. Experiment under a variety of conditions (sunny, cloudy, etc.) and different gear ratios. REQUIRES: Assembly. Phillips Screwdriver. Hobby Knife. Adult Supervision Motor: Solar 01 Battery: Solar(0.5V–1200mA) TAMX7661 - $48.95
| 0.5V-1200 mAh Solar Battery PanelFor moderately experienced model builders. Solar cells convert the energy of the sun or artificial light into electric energy. 0.5V-1200 mAh cell generates measurable electricity even with faint light. Maximum power is generated in bright sunlight. Recommended for use in combination with special solar motors. Panel is metallic blue in color. REQUIRES: Assembly. Phillips Screwdriver. Hobby Knife. Adult Supervision. Dimensions: 133 x 65 x 7.5mm (5.24in. x 2.56in. x .30in.) TAMX7662 - $34.95
| Solar Power Science KitPhotovoltaic Energized Vehicles Build your own solar-powered models and discover how solar cells generate electricity from light. Build six solar powered models including a locomotive, single-prop plane, bulldozer, helicopter, backhoe, and twin-rotor helicopter.
The special solar panel in this kit consists of three solar cells and generates 1.5 volts of electricity in bright sunlight, like a AA battery. A unique cradle holds either the solar panel or the battery, allowing you to switch out the solar panel for a AA battery (not included), depending on the strength of sunlight. You can even use the solar panel to charge up your own rechargeable AA batteries. The solar panel is positionable, so you can maximize its exposure to the sun to generate the most power.
The 24-page color instruction book included in this kit gives step-by-step instructions for assembling the six model vehicles. After you have built the suggested models, you can design your own solar vehicles. Compete with your friends to see whose solar vehicle runs the fastest!
The 177 building pieces included in this set are compatible with those in all Thames & Kosmos Construction Series kits, Physics Series kits, Wind Power, and Hydropower kits. THK555006 - $54.95 $49.95
