Explains different kinds of energy, covering kinetic, potential, gravitational, mechanical, sound, thermal, chemical, electrical, and radiant energy. Also looks at storage, transfer, and dissipation of energy. Includes a short...

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

This is an interactive inquiry where students will investigate the speed of an object and the energy it exerts as it crashes into other objects. Students will understand that the more speed an object has, the more energy it has in a...

Students will model and measure energy transfers from light to heat.

Wind energy is explained well in this module, from its history and how it is produced, to its advantages and disadvantages, and what the future holds for this energy source.

A hands-on instructional activity for helping students understand simple circuits, series circuits, and parallel circuits, and the differences between the three.

A food web is a way of seeing how energy is transferred from organism to organism. All living things need energy. They use it to move, to grow, to reproduce. That energy has to come from someplace. Drawing a food web is a great way to...

The nature of insulators is described at the atomic level. Band gap theory is used to explain what distinguishes insulators from conductors.

If you don't know that the incandescent light was a failure before it was a success, it's easy to write off some modern energy innovations like solar panels because they haven't hit the big time fast enough. Worse, the fairy-tale view of...

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back. What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing.

The students will become the food web in this fun interactive classroom activity. Detailed instructions, background information, guiding questions, and activity worksheets are provided.

Build a water thermometer out of straws and film canisters.

A clear explanation of how dark matter was discovered and why it is important to astronomers.

Describes the seven characteristics that define what life is for biological purposes.

Learn how different protists get their nutrition.
