Several radioactive concepts are explained with the help of animated atoms, complete with their own facial expressions. As physical science pupils watch, they learn about gaining or losing atomic particles, alpha and beta particles, and...

Mr. Andersen introduces viewers to the use of a Geiger Counter. He explains the fundamental forces behind nuclear radiation and differentiates alpha, beta, and gamma radiation. Finally, he teaches how to write nuclear equations. This...

A Geiger counter is used to detect emission of alpha particles, beta particles, and gamma rays. The teacher experiments to find out which materials block each of these forms of radiation. The camera is focused on the measuring instrument...

In this video, Paul Andersen describes some of the properties of electromagnetic radiation. The electromagnetic spectrum varies by wavelength from radio waves to gamma rays. We only see a portion of the spectrum known as visible light. A...

Mr. Andersen explains why radiation occurs and describes the major types of radiation. He also shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom. Nuclear equations are also discussed.
