A car propelled by the reaction between lemon juice and baking soda has more in common with rockets and jet aircraft than one might think. In this video segment adapted from ZOOM, two cast members demonstrate the power of rocket-propelled vehicles and how to exploit the force produced by the carbon dioxide gas. Grades 3-8.
It would seem that bottles of lemon juice and rockets have only their basic shape in common. However, as two cast members from ZOOM demonstrate in this adapted video segment, when baking soda is added to the mix, a plastic bottle can act very much like a real rocket. Grades 3-8.
Finches on the Galapagos Islands have evolved to exploit almost every possible niche. This diagram shows the range of food sources available on the island and the different beak shapes adapted to exploit each of them.
Hear about how respect for Earth can help us attain a more sustainable lifestyle in the face of climate change in this video segment adapted from United Tribes Technical College.
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
In this video segment adapted from ZOOM, cast members make their own hovercraft and demonstrate how the air leaking out of a balloon can make a plastic plate hover above a table.

It takes a thick skin to withstand the hardships that life has to offer. This collection of images shows a variety of animals, each with a slightly different type of protective covering.
This video segment adapted from NOVA explains why ice sheets move. To find out how fast they move, scientists carve a tunnel through a glacier.
What would happen if a portion of the Antarctic Ice Sheet were to melt? This video segment adapted from NOVA uses animations to show the effect of a 6-meter sea-level rise on coastal cities across the world.
What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.
This video segment adapted from NOVA uses microwave images to reveal how sea ice doubles the size of Antarctica each winter. Rare footage shows how sea ice crushed the famous ship Endurance in 1914.
This video segment adapted from Building Big illustrates the strength of the arch in bridge design and construction.
This video segment from Wild Europe: "Wild Arctic" explores the struggle for survival in one of Earth's most extreme environments.
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.
The CyberSquad tries to figure out a table arrangement for 20 workers in this video from Cyberchase.
In this video segment from Cyberchase, Matt tries for a second time to arrange tables and chairs to accommodate 20 workers.
