Natural Selection: How Living Things Change Over Time Grades 6–8 · partly supports this outcome

A peppered moth hunting game over four generations, the Grants' real Galápagos finch data from the 1977 drought, whale fossils in rock-layer order with a forelimb bone comparison, and five case stations on selective breeding and antibiotic resistance. Every lesson runs on printed sheets alone: no materials to buy.

• How fast can people change a species? 50–60 min

  Teams rotate through five printed case stations: one wild plant that became cabbage, kale, broccoli, cauliflower, kohlrabi and Brussels sprouts; dog breeds; the tame foxes of Siberia; bacteria that make human insulin; and bacteria that beat antibiotics. They graph real fox data and decide, case by case, who did the choosing: people or nature.
