Day 56: Radioactive Decay Pre-Lab November 7, 2006

Posted by Admin in Chemistry, Homework.

Today we began a new lab, this one on radioactivity.  To lay the foundation for this lab, we spent the bulk of the hour today discussing and taking notes on radioactivity terminology with the Radioactive Decay Guide.  This information includes definitions of terms such as ‘radioactive decay’, ‘half-life’ and the three types of radioactive decay (alpha, beta, and gamma).  We finished the notes by discussing the formula that allows you to calculate how much of a substance remains radioactive after a given (n) number of half-lives:  (1/2)^n

After completing the notes, students worked individually on the Half-life Pre-Lab.  The pre-lab is due at the start of class tomorrow.  No late passes will be accepted with this assignment!
