To fight climate change, countries need to support research, recruit science experts, and help companies develop clean technology through partnerships and government programs. Citizens also play an important role by staying involved in...

Making things like cement, steel, and chemicals uses a lot of energy and is one of the hardest parts of the economy to clean up. A big problem is that about half the energy is wasted as heat, but better factory design and using things...

Burning coal and natural gas to make electricity causes the most pollution globally, but policies like feed-in tariffs and renewable energy standards help encourage the switch to wind and solar. Texas has been successful in growing clean...

One of the best ways to cut pollution from transportation is to make cities easier to walk or bike in and to improve public transit, like Bus Rapid Transit (BRT), which is cheaper than building subways and still very effective. Cities...

California’s cap-and-trade program is seen as the most successful way to put a price on carbon in the world. It uses a market system where companies buy and sell permits to pollute, but there's a minimum price to keep costs from dropping...

Loudoun County, Virginia has become the center of the internet, with a huge number of data centers storing and powering everything from websites to AI tools. These facilities bring in massive tax revenue but also raise concerns about...

Warming ocean water is weakening a major current system called the Atlantic Meridional Overturning Circulation (AMOC), which helps regulate global weather. Melting ice in Greenland and freshwater from rivers are making the ocean less...

As the planet warms, there's more water vapor in the air, which makes storms stronger and causes heavier rain and snow. This extra heat and humidity can also make it dangerous to live in some places, especially at night when bodies can’t...

The Arctic is warming quickly, and this is changing the jet stream—a strong wind high in the sky that affects weather. The jet stream is becoming slower and more wavy, which causes extreme weather to last longer, like very cold winters...

The oceans are very important in climate change because they take in almost 90% of the heat trapped by greenhouse gases and a lot of carbon dioxide. This makes the oceans warmer and more acidic, which has led to record-low sea ice,...

Meet Benjamin Franklin, one of the most creative and important figures in American history! Franklin was a writer, inventor, scientist, and leader who helped shape the United States. We’ll explore his many inventions, like the lightning...

Discover the incredible history and engineering behind the Hoover Dam in this short and informative video. Learn how this massive concrete structure was built during the Great Depression and why it remains one of the most famous dams in...

“Benjamin Franklin” gives a brief overview of Benjamin Franklin’s greatest accomplishments in science, politics, and civilian life.

“Forms of Energy” explains how potential energy, kinetic energy, and heat energy change into other forms of energy.

“Interconnected Ecosystems” explores interdependent relationships between living things in various biomes.

CAR DOCTOR! Watch Dr. McWheelie try to repair a black sports car—she gets confused!

Dr. McWheelie will explain how solar-powered cars and solar energy work.

The excavator accidentally damaged a power cable, leaving Helper Cars without electricity to repair the bulldozer. The tow truck uses its terminal to fix the cable.

From barbed wire to the automobile, key inventions between 1870 and 1900 revolutionized American farming, communication, entertainment, and transportation.

Between the 1870s and 1900s, the United States experienced a period of rapid economic growth. But beneath the shiny veneer of the Gilded Age lurked profound inequality and widespread want.

This video explores the phenomenon of animals sensing earthquakes before they happen and the causes of earthquakes. It also highlights the importance of understanding and engineering our buildings and cities to withstand earthquakes. The...

What is a superconductor? LK-99 claims to be the first room-temperature superconductor, and if true, it could revolutionize the direction of technology for humanity.

“What Is Energy?” describes what kinds of actions are work, who and what can perform work, and how these things get the energy to do the work.

“Inventions” explains the reasons why things are invented.
