7L.2.1.1.2: Analyze and interpret data for patterns in the fossil record that…

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 do fossils show life has changed? 50–60 min

  Teams build a rock column from printed fossil cards of early whales, from a four-legged land animal to a sea creature with tiny hind legs, and track the changes. Then they compare the bones in a human arm, a cat's leg, a whale's flipper, a bat's wing and a bird's wing, and explain what the shared pattern says about relationships.
