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...

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...

The tremendous growth happening in Africa presents humanity with a once-in-a-species opportunity: to make (nearly) an entire continent skip development of dirty fossil fuels, and be powered by renewable energy instead.

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...

Simka and Nolik's plans to go to the circus with Tom Thomas are cut short when his family gets stuck in the elevator. Helping Papus and Masiya with the repair, the Fixie kids become performers in their own circus!

Electromagnetic waves are fundamental to understanding the nature of light and are oscillations of electric and magnetic fields that travel through space, carrying energy from one place to another. The spectrum of light is a...

In 1897, J.J. Thomson conducted an experiment that led to the discovery of the electron and revolutionized atomic theory by demonstrating that atoms are composed of smaller subatomic particles. Before this, atoms were considered...

This video explores how electrical energy travels from a power plant to your home. It explains the role of electric and magnetic fields in energy transfer and debunks common misconceptions about electron movement. Through the concept of...

In this video, we explore the future of electric cars. While electric vehicles (EVs) date back to 1832, they became overshadowed by gasoline-powered cars due to range and cost issues. However, recent advancements in battery technology,...

Do vehicles really combust into fireballs when they collide? Are doors and hoods sent flying from the blast? Or is it all just movie myth?

Join us as we learn the process behind an explosion, what makes engines work and how fires...
