Ever wonder how a battery works? This segment highlights voltaic cells, their various components and how they operate.

In this interactive activity adapted from the University of Utah's ASPIRE Lab, learn how to measure wavelengths and see how wavelength affects the color of the light that we see.

There's no need to don a space suit if you want to experience weightlessness. In this video segment adapted from ZOOM, two members of the cast drop a cup of water with holes in it to demonstrate how free fall can create a momentary condition of "weightlessness".

This video/animation shows that a molecule of water is made up of oxygen and hydrogen atoms. When oxygen and hydrogen atoms exist alone, their properties are different from the properties they have when they are chemically combined to form a water molecule.

This activity is a field investigation where students design an experiment to determine the coefficient of friction for two contacting surfaces.

Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.

This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.
