Radioactive Decay: a sweet simulation of a half-life

Radioactive Decay: a sweet simulation of a half-life
Type of Resource: Weblink

This weblink is to a lesson that uses M&Ms or Skittles as a model to examine the rate of decay of unstable nuclei.

The lesson allows students to grasp the concept that the exact time a certain nuclei will decay cannot be predicted. A printable worksheet is linked to from the web page.

Students will need to be reminded not to eat in a school science lab. Alternatively, a classroom or café could be used for this activity.
