By the end of today's class, you should be able to do the following:

w Review: Describe the three different types of geotectonic boundaries, including type of movement, type of plates usually involved, and geologic features that can usually be found at each type of boundary.

w Explain the relationship between minerals and rocks.

w Describe some of the characteristics of minerals that allow us to classify them and discern their properties.  (The ones we discussed in class were color, hardness, density/specific gravity, mineral cleavage, and luster.)
 

Rock Your State!  In-class work

w   Working with 2-3 others, make a list of all the kinds of rocks and sediments found in the states you researched. 

w   Create a master list (using sticky notes) of all the rocks/sediments represented for all the states in your group. 

w   For each item on the list, categorize it as a sediment, igneous rock, sedimentary rock, or metamorphic rock. 

w   Next time:  For each type of rock (ig, sed, meta), subdivide the group into smaller classifications.
