How the activity is situated in the course
This activity is divided among two class periods. The groups develop their model during the first period and then all groups present their models during the second class period.

Description of the activity/assignment
In this activity students will examine magmatic differentiation processes using various items that I have provided. In groups they will use these random objects to design a model that can be used to demonstrate one of the magmatic differentiation processes. Each group will present their model, along with an explaination of the process, to the class. Students have one class period to prepare their models and explanations of the differentiation process assigned to them. They present these during the next class period.
Determining whether students have met the goals
Each group is evaluated on their model design and on their oral presentation of the material.
