As many Americans cleared grocery store shelves, purchased shovels and stocked up on batteries for flashlights, municipalities made similar preparations the best way they knew how, spreading salt on roads.

Integrate math and science with The Pop Ecology Files

The lesson, The Pop Ecology Files, provides a fun way to integrate math and science concepts into middle school classrooms. In Part 1, students examine exponential and arithmetic growth rates, and every-day situations where growth occurs in each. Students calculate the difference between saving money so it will grow arithmetically versus exponentially.

Evidence of the Anthropocene: Four Ways Humans Have Changed the Earth
