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...

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...

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...

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 Paul Andersen explains how nuclear energy is released during fission of radioactive uranium. Light water reactors, nuclear waste, and nuclear accidents are also discussed along with the future of nuclear energy.

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 seven museums to visit on a trip to Rome, Italy in this Howcast travel video.

In this video, I summarize All Nuclear Physics in about 10 minutes. Atoms are made of a positively charged nucleus surrounded by negatively charged electrons. The nuclei of atoms are made up of protons and neutrons. These are called...

Volleyball is a fast paced, action packed game for people of all ages. Unlike basketball, the ball is not allowed to be caught or thrown, but “spiked” or punched, instead.

Coach Socrates and Miss Palomine talk about various non locomotor skills. Miss Palomine demonstrates them. They then use their non locomotor skills and their imaginations to play a game of “Movement Charades.”

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...
