Use this set of interactive labs from the Annenberg Media course "The Habitable Planet" to explore the intersection of math and science. Labs tie together common concepts around the themes of:

• Carbon
• Demographics
• Disease
• Ecology
• Energy

Each lab consists of a simulator with a series of questions to think about as you explore scenarios, as well as a data table to help students track their data as they progress.
