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

In this activity, students learn how an animal's sense of hearing is adapted to -- as well as affected by -- its environment. They begin by exploring how a shark's senses enable it to be an efficient predator. Students then compare a shark's senses to those of a land animal of their choice, and discover how each animal's senses are adapted to its particular environment. Next, they focus on the sense of hearing, and a common cause of hearing loss: continual exposure to loud noises. Students learn how a change in the way that an Arctic community hunts -- using rifles instead of harpoons -- has caused widespread hearing loss. Finally, students research noise levels in their environment and conduct a public awareness campaign about noise pollution and the associated hearing loss.

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.
