Students will use this online Radioactive Decay Calculator to compute radioactive decay, timed decay, and timed solid disposal for a databank containing 116 isotopes. This calculator also features University of British Columbia disposal...

A laboratory activity that teaches the difficult concept of radioactive decay by means of a fluid (shampoo) flowing through holes from an upper to a lower beaker. Using the exponential decay equation, students then 'date' the shampoo....

[Free Registration/Login may be required to access all resource tools.] How scientists can use radioactive decay to find the age of certain materials.

Students will learn how to estimate time of death by using a lab that models carbon dating and radioactive decay. Activity pages complete with calculator keystroke instructions and screenprints are included in this lesson plan based on...

Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that...

In this activity, students gain a better understanding of radioactive dating and half-lives by using M&Ms to demonstrate the idea of radioactive decay. They will be able to see how scientists can determine the age of rocks by looking...

Article describing efforts in the 19th and 20th centuries to determine the Earth's age, particularly using naturally occurring radioactivity. It notes that scientific disciplines frequently overlap in the work they do. Questions are...

[Free Registration/Login Required] Study the basics of radioactive decay and the properties of atomic nuclei in Marie Curie's laboratory and classroom. A PDF worksheet and a video tutorial are also available. [3:32]

[Free Registration/Login may be required to access all resource tools.] Explains radioactive half-life and radioactive dating, and demonstrates how to solve problems with each.

This set of activities from the Milton J. Rubenstein Museum of Science & Technology has students investigating how relative dating and absolute dating methods are used to determine the age of rocks and fossils.

A virtual lab allows you to do radiometric dating on dinosaur bones. You'll be using a mass spectrometer and utilizing several steps of the scientific method.

This educational resource provides information to help students understand the concept of half life.
