Educational Solar Panels - Innovative Solar Solutions. Educational solar panels are the perfect way to introduce adults and children alike to the world of solar power.
For most, the easiest, most engaging and most lasting way to learn is through a hands-on experience. Educational solar panels give that experience in a safe, controlled and exciting way. Educational solar panels are fully functioning (when you expose them to light, they will actually produce power) and often come matched with a variety of different toys, or other small solar applications that actually demonstrates how the technology works visually.
For instance, some of the most popular educational solar panels are included in solar car kits, or other solar toys and solar demo kits, which allow the user to build, or connect, small motors, lights, etc to a solar panel and use the sun to make it go, light up or whatever the goal happens to be. Educational solar panels are available for every age group, and every skill level, and make great projects for: DIY Solar Panel Kits - Innovative Solar Solutions.

DIY Solar iPhone Charger Made with Altoids Tin Is Less Than $20. I love my smartphone.
Love it! But traipsing around San Francisco, tweeting, facebooking, and foursquare-ing surely takes a toll on its battery life. With each percentage drop in battery life, it feels like somewhere a kitten has died. Theme Pages. Hands-on Science Videos at Steve Spangler Science. Science Experiments. Using models to teach electricity—The CASTLE project. Science fair project: Ultra-simple Electric Generator, spinning magnets. All metals contain a movable substance called "electric charge".
Even uncharged wires are full of charge! After all, the atoms of the metal are made half of positive protons and half of negative electrons. Metals are special because their electrons don't stay connected to the metal atoms, instead they fly around inside the metal and form a type of electric "liquid" inside the wires. All wires are full of electric fluid. Modern scientists call this the "electron sea" or "electron gas. " When a circle of wire surrounds a magnetic field, and the magnetic field then changes, a circular "pressure" called Voltage appears. Generators don't have just one circle of wire. Why is this generator AC and not DC? If you want a DC generator, you'll have to add a special reversing switch to the magnet shaft. Now for the light bulb. So, just connect a light bulb to a coil of wire, place a short powerful magnet in the coil, then flip the magnet fast.
Disconnect one wire from the light bulb. Convert to DC: Articles on "Electricity" . . . . WJ Beaty. William J.

It may sound strange, but it's true. In this episode, Julie and Robert conduct an experiment that shows just how powerful air pressure can become. Gravity Gravity is the force that holds us on the planet -- but how does it actually work?

One side gets hot and the other side gets cool. Therefore, they can be used to either warm something up or cool something down, depending on which side you use. You can also take advantage of a temperature differential to generate electricity. The thermal tape listed below works very well to attach heat sinks to the hot side. This Peltier works very well as long as you remove the heat from the hot side.
