Crust Density Lesson

This is an activity where three different types of rocks (symbolic of different parts of earth’s crust) are examined and their density determined and observed.

As I delve into the study of earth science, I have found that a key component of my own understanding is truly understanding the concept of density and how it affects the earth’s makeup.   I liked this lab specifically because it uses rocks and not liquids, like many other similar labs available.   I hope that this concept at the very beginning of their earth science class would help them understand more difficult and complex notions later.
