This Science NetLinks lesson is the first in a three-lesson series about isotopes, radioactive decay, and the nucleus. This lesson helps students build their understanding of the properties of matter. Specifically, it will help them understand that average atomic mass is not a simple average, but is weighted according to percent abundance.
Before working on this lesson, students should be familiar with the periodic table and should have had some basic instruction in the following concepts: isotopes, mass number, and atomic number.
