An educational solar powered robot and mini solar toy. He's small, but he's an amazing attention-getter!
Explore the potential of solar power with this neat science gardet. The Solar Grasshopper shows the power of solar energy.
It shows how solar energy can be used to generate electricity which can then be used to drive a motor. Illustrates how radiant energy from the sun can be converted to electrical energy with a PV cell.
The tiny motor inside the grasshopper transforms this free energy from the sun into motion.
It works best in direct sunlight or very close to a non-florescent light bulb. This is a good demonstartion of the difference in the energy given off by the sun, by incandescent lightbulbs and by low-energy bulbs.
An attention-grabbing demonstration of solar power for a science fair project, class discussion, or just play.
In bright light, the solar grasshopper is frantic! It wiggles about, waves its antennae, jiggles its eyes, makes a buzzing sound - just like a real grasshopper.
Apart from being great fun, this clever little machine affords lots of lerning opportunities:
- how different light sources differ in energy content
- conversion of energy from one form to another
- difference in energy output from objects of apparently similar brighness
- how light can be converted to electricity
- how electricity is converted to rotational motion
- how rotational motion is converted to vibration
- how vibration produces both motion and sound
- do real grasshoppers use solar energy too?
- how?
- why?
