Students can use M&M's to model a decay equation - exponential equations.

Explore geologic time of the Earth and learn how radioactive decay helps to establish a timeline.

In this task on exponential decay, students calculate what the amount of Carbon 14 left in a preserved plant will be as time passes and when one microgram will be all that is left. Aligns with F-LE.A.1.c.

Substitute coins for radiation. A coin experiment using radioactive decay.

Graph exponential functions. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice problems that each illustrate a different use of the Law of Exponential Change. Examples and explanations are provided. Great review for the AP Calculus test!

This interactive unit will take students up close and personal with the nuclei of atoms as they discover some of their more intimate process. These will include radioactive decay, nuclear fission, and nuclear fusion.

This is a chart showing Selected Radioactive Isotopes including: Decay Mode(s), Energy(MeV), y-Ray Energy(MeV), and more.

Learn about milk and adult teeth, the types of teeth we have and their functions, the anatomy of a tooth, dental decay and tooth plaque, how to take care of your teeth, what dental braces do, what causes bad breath or halitosis, and why...

An introduction to exponential equations that describe growth and decay over time. Variables and constants in the equation are explained.

An experiment that will help students in determining the half-life of a radioactive element.

Through informational text, interactive activities, and virtual animations students learn about the atomic nucleus, fission, fusion, and radioactive decay.

[Free Registration/Login may be required to access all resource tools.] In this module, students will explore the radioactive decay process in terms of balanced nuclear equations to discover the concept of half-life.
