1. Conceptual survey: “Evolve” Please get out a piece of paper

2. In this task... • You will be shown a series of statements. Read them carefully, then sort them into one of two categories: • A = An example of evolution • B = Not an example of evolution • Then explain your choice in writing.

3. Statement 1 of 7 • An infant grows into a child and then into an adult. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

4. Statement 2 of 7 • Antibiotic-resistant strains of tuberculosis bacteria appear several decades after tuberculosis was first treated with antibiotics. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

5. Statement 3 of 7 • Raccoons that normally eat wild food discover cat food left outdoors on someone’s porch. They learn to find cat food at other houses. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

6. Statement 4 of 7 • A new pesticide is developed to kill aphids, but ten years later the aphid population increases again and the pesticide is no longer effective. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

7. Statement 5 of 7 • An athlete works out five days a week and develops larger muscles. She continues working out for many years to maintain her muscle size. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

8. Statement 6 of 7 • A mutation appears in a population of plants with red flowers. Plants with this mutation have white flowers, which do not attract pollinators well. This lowers their reproductive rate.The white mutation disappears from the population after twenty generations. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

9. Statement 7 of 7 • A caterpillar makes a chrysalis and metamorphoses into a butterfly which hatches out of the chrysalis. • A = An example of evolution • B = Not an example of evolution • Please explain your choice.

10. With a group… • Read each of these scenarios and decide if this IS or is NOT an example of what scientists mean when they say “evolution.” • An infant grows into a child and then into an adult. • Antibiotic-resistant strains of tuberculosis bacteria appeared several decades after tuberculosis was first treated with antibiotics. • Raccoons that normally eat wild food discover cat food left outdoors on someone’s porch. They learn to find cat food at other houses.
