Temperature Profiles in Permafrost
In this STELLA modeling exercise, students create a model of heat flow in the outer kilometer of Earth's crust. Then they perform experiments to change the air temperature variable in an attempt to replicate the findings of Lachenbruch and Marshall (1986) who used inflections in the geothermal gradient of Alaskan permafrost to search for evidence of recent climatic change. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

Inside Caitlin's Head
In the 1830s, George Catlin (1796–1872) packed his paintbrushes and trekked through remote Indian country in the Great Plains. Committed to documenting traditional Native culture, he visited more than 140 tribes and painted more than 325 portraits and 200 scenes of American Indian life. Catlin's prolific works, both his art and his writings, illustrate Indian cultures on the precipice of radical change—change that would come with U.S. expansion into tribal territories.

The Changing Workplace
The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the count
