In this video, an environmental technologist visits an abandoned coal mine in Kentucky to talk about how a remediation system (a series of settling ponds and treatment cells) is neutralizing the acid drainage flowing from the mine and keeping it from damaging a creek downstream.

Our brains control every movement we make. Most of us take for granted our ability to pick up a cup or change the television station. However, for people who have lost a limb or become paralyzed, the inability to do these things means a loss of freedom and independence. This video segment from Greater Boston describes how neuroscientists and bioengineers have teamed up to create a system that allows people who have lost motor functions to control electronic devices through their thoughts alone. Grades 6-12

Do you need proof that driving is a dangerous activity? More Americans have died in car crashes over the past 100 years than in all the wars the U.S. has ever fought combined. More than 40,000 Americans die each year on the nation's highways, most as the result of high-speed collisions. In this video segment adapted from NOVA, learn how engineers developed the air bag, an important automobile-safety device now found in most cars.
Recommended for: Grades 3-12

This video provides a real-life example of the scientific method: testing hypotheses about which plants will grow most successfully on a green roof in Kentucky.

In this brief video, a biologist talks about the macroinvertebrates (typically aquatic insects) that form the basis of food webs in healthy Kentucky streams.

The engineering design process involves many steps. Not only must an engineer be able to devise a solution to a problem, he or she must also be ready to test and evaluate that solution to reach the best result. To successfully complete the design process, an engineer must be able to identify design flaws and learn from his or her mistakes. In this video segment adapted from ZOOM, learn about the design process as cast members create automatic door openers that enable them to open their bedroom doors while lying on their beds. For grades 3-8.

This animated essay from the NOVA Web site examines the design of Galileo's refracting telescope and Sir Isaac Newton's reflecting telescope.

In this video segment adapted from NOVA scienceNOW, scientists discuss their attempts to grow human body parts in a jar.

In this video adapted from NASA, two members of a NASA research team working to produce carbon nanotubes share some background behind this new technology, show examples of how it will be useful, and explain the various tests being performed to ensure readiness for spaceflight.

Find out how serious head concussions can be in this video segment adapted from NOVA scienceNOW.

In this interactive activity from the Building Big Web site, use your knowledge of bridge design to match the right bridge to the right location in a fictitious city.

Survey potential bridge sites, research bridge design, and select the right bridge for the right location in this interactive activity from the NOVA Web site.

NASA engineers test Curiosity, the Mars Science Laboratory rover, and demonstrate its material properties, its handling and mobility, and its design features in this NASA video.

In this video segment adapted from ZOOM, the cast shows how the 34 steps in their Rube Goldberg invention use everything from gravity to carbon dioxide gas in order to accomplish one simple task: pouring a glass of milk.

In this video segment from ZOOM, Jillian explains how her simple machine uses marbles, levers, flowing sand, and a spinning wheel to water a plant.

This video segment adapted from AMERICAN EXPERIENCE tells the story of how environmentalists, Alaska Native peoples, and engineers concerned about the effects of permafrost challenged plans for the Alaska oil pipeline.

This video excerpt from NOVA’s Making Stuff: Cleaner and accompanying demonstration introduce students to the production and importance of bioplastics, or plastics made from plant or animal products.

In this video segment adapted from NOVA, find out how cars made of a material stronger than steel and half the weight can help combat climate change.

Learn about the Chandra X-Ray Observatory's telescope system, science instruments, and spacecraft system in this interactive activity adapted from NASA.

This video segment from Building Big illustrates the basic design principles of the Clifton Suspension Bridge in Bristol, England. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.
