I am a big believer in making a model of systems.  I beleive that making models helps a student see the system and how it works much better than if you try and learn it from a book.  In my inquiry experience I had students create a model of a continental margin our of clay or by drawing it.  The margin that they created could have been one of two types (either active or passive) based on the location in the world that I gave them.  This type of activity stimulates the students thinking and makes them apply knowledge of the system while making their model, demonstrating higher forms of thinking.  I think my model project went fairly well and I think the assessment data suggests that for the most part my students learned the objectives.  I have attached a few pictures of the stduents' work for your review.
