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

Plate Tectonics

*  Review: Describe the direction of movement at each of the three types of plate boundaries.

*  Review: List and describe the geologic features you would find at each of the types of plate boundaries.  Use sketches to illustrate each type, and give real-world examples of each.

* Continue constructing your map of plate boundaries by adding the convergent zones.  Be sure to distinguish among boundaries with continental-continental, continental-oceanic, and oceanic-oceanic plates.  The base map we are using can be found at this link.  To figure out where boundaries are, see the map in your textbook p. 224-5 or online information about plate tectonics.

* Examine plate movements throughout earth history by looking at animations online.  To find animations, google "plate tectonics" and "animations".  The first hit there, in particular (from the Univ of California at Berkeley), has a nice Quicktime movie of plate movements through the last 750 million years of Earth history.  Take a look at other sites you find, as well, to see different ways of portraying how Earth has looked through time.


* Explain the difference between rocks and minerals.

* Demonstrate how to use mineral testing tools to explore the properties of hand samples of minerals.

* List and describe at least five mineral properties, and select a few hand samples that exemplify each property.

* Use a mineral key to associate names of five minerals with their diagnostic properties.
