Near-Earth Objects, or NEO's, cross our planet's orbit on a regular basis, but only a handful are large enough to pose a threat. One of these objects is asteroid 1999 RQ36, a "leftover" from the formation of our solar system...

Can AI help catch oceanic outlaws? From drug smugglers to modern-day pirates, maritime crime fighter Dyhia Belhabib introduces Heva: an AI-powered tool that aggregates international criminal records to detect and stop crime that might...

In this video Paul Andersen explains how a radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nuclei can not be determined but probability is useful in predicting the...

This video explains the differences between copper and helium, highlighting their properties as elements. It introduces the concept of elements as chemically pure substances that cannot be further simplified. The video also mentions...

How to deStress with progressive muscle relaxation. In this video I teach you how to do progressive muscle relaxation. Progressive muscle relaxation is a meditation technique used to reduce muscle tension. As you constantly hunch over a...

When a radioactive atom goes through alpha or beta decay, the atom itself changes into a different element. For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. It’s impossible to predict when an individual atom...

In this video, students learn about radioactive decay and how to solve half-life models. The teacher explains the concepts using examples and equations, demonstrating how to calculate the time it takes for a substance to decay to half...

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....

This video is a quiz over the topics covered in the Earth's Nearest Neighbors series. In this series, we explore the fascinating characteristics of our solar system, focusing on the planets closest to the sun - Mercury, Venus, Earth, and...

NASA's NPP mission will continue collecting critical climate data to help scientist unravel the mysteries of climate change. This fun interactive mission overview video featuring TV meteorologists Topper Shutt (WUSA9), Veronica Johnson...

After the Chernobyl Disaster, researchers have been studying the movement of radioactive contamination all over central Europe. Fortunately, that radioactive contamination is decreasing in just about every living thing, except for one...

In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

Mr. Andersen explains how carbon-14 dating can be used to date ancient material. The half-life of radioactive carbon into nitrogen is also discussed.

In this video Paul Andersen describes the characteristics of the rate constant in chemical reactions. The rate constant is highly variable in reactions and must be determined experimentally. The rate constant is dependent on both...

This nugget explains the concept of radioactivity, its types and mathematical expressions and examples.

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...

Howcast - Learn about the top eight places to eat and drink in San Francisco, California in this Howcast travel video.

Pupil outcome: I can describe ways in which India is changing and explain why the country is called a global superpower. Key learning points: - India has the fifth largest economy in the world. - India's economy was worth $3.6 trillion...

Cosmic Inflation occurred when the entire universe shortly after its beginning, expanded exponentially...

In this episode, Hank welcomes you to the new age, to the new age, welcome to the new age. Here he'll talk about transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission....

In this video, the concept of exponential decay and the half-life of radioactive elements, specifically cesium-137, are explained. The video demonstrates how to use an exponential decay function to predict the amount of cesium-137...
