Redox Equations and the Half-Reaction Method

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

What is half-life and how can decay be used to date items? Viewers find out in this video that details half-life and radioactive decay, as well as the difference between alpha and beta decay.

Ready to tame LEO the lion before he says GER? Get chemistry scholars acquainted with the half reaction method for handling redox equations using a video from the JFR Science playlist. Step-by-step instructions and great tips provide...

Participate in a little chemistry Q and A! Part of a larger series on reactions, an informative lesson takes questions from viewers and crafts responses. The video explains how we arrive at an accurate half-life of a radioactive...

Does a radioactive cat have 18 half-lives? An understanding of half-life is important in both chemistry and biology, so start your young scientists off the right way — with the good foundation provided by a video that begins with a graph...

Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson of seven integrating chemistry and algebra. Combining...

A video lecture discussing radioactive decay and half lives. Understand how half life and the mass of the compound remaining is calculated by following the examples given in the lecture. [12:31]

Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.
