Title: How Does Radioactive Decay Work?
Url: http://serc.carleton.edu/quantskills/methods/quantlit/RadDecay.html
Creator: Wenner, Jennifer M.
Publisher: Science Education Resource Center
Description: This teacher's guide with exercises is intended to help teach the topics of radioactive decay and its use to determine age. It identifies four main concepts that students are likely to struggle with: spontaneity (randomness) of radioactive decay; the importance of isotopes; the concept of half-life; and how to choose which system of isotopes to use to determine age. The guide presents suggestions on how to make these ideas more understandable, and provides three exercises that can be used to demonstrate radioactive decay. Links to additional materials and information are embedded in the resource.
