Redox Equations and the Half-Reaction Method

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.

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.

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...

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...

High schoolers generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several...

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...
