Students describe how radioactivity relates to alpha and beta particles. Using their properties, they write a descriptive paper about the gamma rays and alpha and beta particles. They calculate q-values and the half-life of a given...

[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.

[Free Registration/Login may be required to access all resource tools.] The half-life of a radioisotope, rates of radioactive decay and variation in half-lives in different radioisotopes.

[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.

[Free Registration/Login may be required to access all resource tools.] Explains radioactive dating, how it works, and how carbon-14 is used to date the remains of living things.

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...

This lesson focuses on radioactive emissions including radioactive decay, half-life, using half-life, how to calculate net decline, a table showing how the count rate of an isotope might change over time, and a link to a test.

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...

[Free Registration/Login may be required to access all resource tools.] An overview of radioactive decay.

A very readable account of the discovery of radioactivity and its properties.

A complete learning module with interactive activities as well as informational text to help students distinguish the characteristics and components of radioactivity.

Explore various types of radiometric dating.

Use interactive graphs and other diagrams to answer questions about carbon dating.

In this amazing interactive tutorial you will learn about what methods are used by geologists to learn about the history of the Earth. Investigate a geologic time scale and learn about how scientists have developed and organized a record...

The team at Periodicvideos has created a TED-Ed Lesson for every element of the periodic table. Because of its radioactivity and short half-life, astatine is an element few chemists come into contact with. [0:34]

Investigate new discussions on the presence of humans in North America, and emulate the work of archeologists in dating artifacts at a dig site. Use clay to model how the radioactive isotope of carbon (C14) is used in dating organic...
