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....

These eleven problems will challenge your class to balance the redox reactions using the "half-reaction method."  This sheet would provide good practice for group or team work as the "half" equations can be checked against each other.

The breakdown of your breakfast and plants photosynthesizing all relate to the simple movement of electrons. Learn about the complex manner of redox reactions, where electrons move from one compound to another, changing and propelling...

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.

Explore the science of radioactivity! A very thorough video lesson begins with an explanation of the chemical structure of radiation. It includes descriptions of benefits of radioactivity and half-life calculations.

Like anything that is made up of living matter, atoms are subject to decay. In the world of chemistry, there are different types of decay, which is what this video explores. There are mathematical equations which go along with each type...

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...

There are no tricks here! Young scholars learn about the concept of centripetal acceleration by studying the design of the snowboarding half pipe. A video lesson describes how the half pipe design affects the motion of the boarders.

A lesson plan prompts scholars to use candy to figure half-life. Combining class data allows them to find the graph of best fit and to determine if it should be linear or exponential. 

Balancing chemical equations is difficult even for top learners, and oxidation-reduction reactions can be the most difficult to understand. Using the half-reaction method, the instructor demonstrates four examples. Learners can watch the...
