In this video, we explore the weather in space, focusing on the sun and its impact on Earth. We learn about solar wind, auroras, solar storms, and their effects on our communication systems and astronauts in space. The video highlights...

Solar winds are super fast, nuclear winds emitted by the sun. Were these winds to reach Earth's surface, they would cause a lot of damage. Find out what makes solar winds so dangerous andwWhat protects Earth from this weather.

Through telescopic video and photos combined with animated graphics, students will learn about the layers of the sun and its effects on earth, the moon and all the objects in our solar system and the universe.

Black holes are regions in space and time with an incredibly strong gravitational pull. Nothing, not even light, can escape a black hole. While we cannot observe them directly, scientists study the particles and radiation being drawn...

Hawking radiation was first discovered by English scientist Stephen Hawking in 1974. Prior to this discovery, our knowledge of black holes was very limited. It was believed that black holes were completely black and that they did not...

Overview of the use of radioactive isotopes in medicine to diagnose certain ailments.

Nuclear power stations produce electricity, which of course is extremely useful. However, they also make radioactive waste. When items have no further use and have radioactivity above certain levels, they are known as radioactive waste....

The 3 simple ingredients of sun, air and water lead to every type of weather on Earth. The atmosphere is constantly trying to balance heat from the sun with water vapor and air to create a dynamic planet. The unique properties of the...

It’s hard for those of us in the modern era to grasp the true horror of the Chernobyl disaster. Even a deep dive into the Chernobyl meltdown timeline can only reveal so much about the very real, visceral consequences of the event....

At the beginning of this series, we talked about the Big Bang, which was the beginning of our universe, and what happened in the early epochs thereafter. But what we didn't talk about was how we know all that stuff! What is the evidence...

Black holes are not as black as we once thought. They are theorized to die a slow death by evaporation, emitting energy known as Hawking radiation. But the mechanism for evaporation is not well understood. Then again, no one has ever...

Air and moisture in different quantities comprise our atmosphere. The sun is the energy source that causes temperature change, wind, clouds, rain, dew, blue skies and rainbows. See how to build an instrument called a "sling psychrometer"...

NASA’s InSight mission marks the first time humans have managed to directly map the internal layering of a planet other than Earth.

This live-action video program is about ectotherms. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated graphics...

This video explores the daily condition of the Earth's atmosphere. The factors that influence the atmosphere and cause weather are discussed. Special emphasis is given to the global processes that generate weather patterns. Other...

Everyday we experience weather. This interesting series of programs helps students understand the factors that contribute to weather formation. Real-life examples enable students to appreciate the different aspects of weather....

Atmosphere Set: 2. This clip explains how the ozone layer is formed in Earth's atmosphere. The role of ozone is described and the destructive effects on the ozone layer of chlorofluorocarbons (CFCS) is explained.

Students will learn about the different layers of the atmosphere. The changes in the atmosphere are explained using examples of contemporary environmental conditions brought about by human behavior. The oxygen cycle and the carbon cycle...
