Teachers, save “Natural Selection Simulation_Mystery Sci…” to assign it to your class.

To show how selection can happen without people, play the Peppered Moth game and share your thinking about your results. 1. click 2. use the to access the game and read “how to play” aloud. At the start of the game, half the moths are light-colored and half are dark. 3. Click “play game.” Choose to hunt for moths among trees with pale bark or trees with dark bark.

In the upper left corner, you’ll see a timer and a count of how many moths you’ve eaten. Down below, you’ll see graphs that show how you have affected the moth population. 5. When the game ends, take a screenshot of how the moth population changed. 6. Then, play again. This time choose the other type of forest. Once again, at the start, half the moths are light-colored and half are dark. At the end of that game, take another screenshot of the results. 7. When finished, go back to this activity and upload your screenshots and answer the question: How would you explain your moth population results? Use the or tools to record your thinking. 8.
