Carbon Connections

Carbon Connections is an inquiry-based, three-unit, online curriculum designed to improve students' understanding of the carbon cycle and the science of Earth's climate. The units bring to life abstract concepts relating the carbon cycle to climate science, and guide students as they investigate and manipulate global data sets from NASA and other scientists in an interactive, web-based environment. The three units follow carbon in past, present, and future contexts, designed to enhance students’ understanding of the carbon cycle and the science of global climate change.

The web materials plus hands-on investigations are targeted to supplement high school courses (grades 9-12) in biology (general, IB, or AP biology), Earth sciences, or environmental sciences courses.
