Resource	Grade Level	Media Type
Are We Alone? This video segment adapted from NOVA features a variety of scientific perspectives on the age old question, "Are we alone in the universe?" Animations make vivid the improbability that we could intercept a radio wave signaling extra terrestrial intelligence.	6-12	QuickTime Video
Cave Formation: Biogeochemical Cycles This video segment adapted from NOVA chronicles the discoveries that led to a radical new theory in which living organisms, not just geological processes, play an active role in cave formation.	6-12	QuickTime Video
Climate Change This video segment adapted from NOVA explains the difference between weather and climate and features groundbreaking analysis revealing that Earth's climate has changed much faster than previously believed.	6-12	QuickTime Video
Construct an Aqueduct Think like an engineer and build an aqueduct in this interactive activity from the NOVA Web site.	3-12	Shockwave Interactive
Deep-Sea Vents and Life's Origins Deep-sea vents are home to life forms that do not rely on the Sun's energy. They depend instead on energy from volcanoes on the ocean floor. This video segment adapted from NOVA hypothesizes that life on Earth may have begun in this extreme environment.	3-12	QuickTime Video
Energy Transfer in a Trebuchet On NOVA, a team of carpenters, timber framers, engineers, and historians recreate a medieval throwing machine called a trebuchet. This adapted video segment explores how understanding energy transfer informs their design.	6-12	QuickTime Video
Finding Lucy This Evolution video segment depicts the landmark hominid fossil finds by Don Johanson and his team in Ethiopia.	9-12	QuickTime Video
Genetic Variation This video segment from NOVA: "Cracking the Code of Life" explores the genetic similarities and differences among organisms.	9-12	QuickTime Video
