Ecosystems and Biomes: Who Depends on Whom Grades 6–8

Real wolf and moose counts from Isle Royale, a sixteen-card sort of competitors, predators, parasites and partners, six real climate graphs to match to their biomes, and a sea wall against a salt marsh. Four print-and-go lessons on populations, interactions, biomes and the services ecosystems give us.

• What happens to a population when food runs out? 50–60 min

  Teams graph twelve years of real wolf and moose counts from Isle Royale, an island in Lake Superior, then rotate through evidence stations to explain why the moose boomed to about 2,400 and crashed to about 500. They finish by predicting what happens to any population when its food runs short.
