In this video segment from Cyberchase, the CyberSquad replaces a piece of track to get the Madre Bonita Express to the Mother's Day harvest.

This video adapted from the Valdez Museum & Historical Archive, explores what happened during the Great Alaska Earthquake of 1964 through original footage, first-person accounts, and animations illustrating plate tectonics.

In this video adapted from ATETV, learn how Bristol Community College promotes internships and co-ops to prepare students for work in technology-related careers.

Children learn how seasonal weather changes affect everything, from the behavior of animals to the way we dress and play.

This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe in more depth.

This lesson will help the students understand that science theories change in the face of new evidence, but those changes can be slow in coming.

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.

For years, our oceans have been hard at work absorbing the carbon dioxide that humans create through burning fossil fuels. Find out what effect that extra CO2 is having on our seas.

In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.

In this video segment adapted from ZOOM, two cast members demonstrate what happens when vinegar is added to baking soda inside a container. The resulting chemical reaction produces enough carbon dioxide to launch their paper rocket skyward.
Recommended for: Grades K-5

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.

Students examine some of the behaviors and physical characteristics that enable organisms to live successfully in their environment.

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.

Students practice carefully lining up decimal places while calculating sums of decimals that total more than one.

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

In this video from Nature, geological detectives use ancient diamonds to learn more about Earth's inner layers.

This video segment adapted from Big River: A King Corn Companion shows how agricultural chemicals from the Midwest that travel downstream in water runoff create a vast marine dead zone in the Gulf of Mexico.

Learn how agricultural technology is changing farming, and one student's life, in this video adapted from Pathways to Technology.
