Another resource you might explore is a software package titled "GETIT" (Geoscience Education Through Interactive Technology). It is highly interactive and focused exploring how energy flow (thermodynamics) drives Earth's systems. It specifically explores volcanoes, earthquakes, plate tectonics (internal heat flow), and hurricanes (surface heat flow). It is used here in San Antonio by the Northside school district, the largest in San Antonio. The website is www.cambriansystems.com/getit.htm. Also look at the activities list at http://www.cambriansystems.com/actmtrx.pdf. I use GETIT here in my introductory classes to illustrate complex concepts. Works great.

Does anyone know of an age-appropriate text I could use? Hands- on, constructivist approach definitely preferred! (And quick! Texts have to be chosen by next week!)
