Humans have become addicted to fossil fuels. From pumping oil into our cars, to burning natural gas to heat our water, or using coal to create electricity that lights our homes, we are constantly relying on these nonrenewable resources....

Introduce the idea of wind power. Have your class make a simple weather vane with a plastic straw, tape, a pencil, and other items found in your class. This film could be used to explore wind power and alternative energy sources.

On a bold, computer-generated animation of a landscape appears a city, power plants, wind turbines, and smaller, decentralized combined heat and power (CHP) plants. The intent is to show how CHP plants can be incorporated into the energy...

Explore the various sources of energy with your junior scientists. Rather than a video, this is a series of slides that the narrator simply reads aloud. Unless your learners have the energy to keep themselves alert, this may not be the...

Solar energy and biofuels are introduced as future alternative sources of energy. The National Renewable Energy Laboratory has made it their mission to make these alternatives more efficient and competitive with the use of fossil fuels....

With a variety of video clips and diagrams, the narrator acquaints the audience with three sources of alternative energy: the sun, the wind, and water. This is a homemade video created as a homework assignment, but it is well-done and...

The main objective of this video lesson is to bring the students' attention to the importance of basic and natural sciences in our lives. The lesson will introduce a topic (sustainable energy) that is related mainly to chemistry and is...

In this video segment adapted from NOVA scienceNOW, hydrogen fuel cell cars promise pollution-free driving, but will we see them anytime soon?
