This video segment adapted from the Space Telescope Science Institute shows what the Hubble telescope found when it stared at a single, nearly empty spot in the sky for 10 days in 1995. The unexpected result was a picture of a multitude of galaxies stretching into the distance.

Students learn how the human body self-regulates to maintain a stable internal environment despite changes in the external environment.

In this video segment adapted from NOVA: Judgment Day: Intelligent Design on Trial, learn how modern genetics and molecular biology offer compelling support for evolution. The video features an interview with biologist Ken Miller.

Students investigate hominid evolution. They learn the difference between a relative and an ancestor, study the emergence of bipedalism, and chart patterns of hominid migration.

This video segment from NOVA: "Cracking the Code of Life" looks at the meaning and significance of the effort to decode the human genome.

In this video segment adapted from the National Film Board of Canada, learn how the Inuit people have used their traditional knowledge to understand and adapt to changes in their Arctic environment, particularly when hunting and navigating the landscape.

In this video segment from The Secret of Life Teaching Modules: "Nothing to Sneeze At: Viruses," watch as a virus attacks a cell, and learn how the immune system reacts to this onslaught.

This video segment adapted from A Science Odyssey looks at the invention of the automobile and the development of mass production.

This video segment adapted from A Science Odyssey looks at the invention of nylon.

This video segment adapted from A Science Odyssey considers modern technology's impact on society.

In this video segment adapted from NASA, astronomer Michelle Thaller introduces the world of infrared light and demonstrates how infrared cameras allow us to see more than what the naked eye can perceive.

This video segment adapted from NOVA illustrates why carbon is at the center of life on Earth. It also asks whether carbon-based life might exist on other planets.

In this interactive activity adapted from Annenberg Learner's Teaching Math Grades 6–8, explore some of the ways graphs can represent mathematical data contained in a story.

This video segment from NOVA: "The Sea Behind the Dunes" explores the community of organisms that exists in the New England tidal marsh.

Students use media resources and an in-class investigation to explore the types of energy within different types of systems. They also use the formulas for kinetic and potential energy to examine the path of a projectile.

In this video segment adapted from ZOOM, the cast builds a suspension bridge from a couple of chairs, some cardboard, and rope.

In this video segment adapted from NOVA, a scientist explains the unexpected heat source fueling widespread volcanic activity on Io, a moon of Jupiter that many had previously assumed to be frozen.

In this interactive activity from ChemThink, learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.

In this video segment from Greater Boston, learn about conflicting theories regarding the cause of autism.

In this video segment adapted from NOVA scienceNOW, follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.
