The students will evaluate their personal radiation dose. They will develop an understanding of the term radiation and how it relates to everyday life. The will simulate how radioactive material decays and apply the term half-life....

Wealth, and its public display, was probably used to establish status in early Anglo-Saxon society much as it is today. The purse lid from Sutton Hoo is the richest of its kind yet found. The lid was made to cover a leather pouch...

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.

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

Learners use M&M's and a graphing calculator to collect and graph data. This activity helps them to understand exponential functions and the concept of half-life.

Given illustrations, diagrams, or descriptions, students will identify alpha, beta, or gamma radiation.
