  2. Natural SelectionSurvival of the Fittest • Standard 7.d: Students know variation within a species increases the likelihood that at least some members of a species will survive under changed environmental conditions. Students should be able to: • Predict how differing genetic traits will increase probability of survival in a given environment. • Develop a hypothesis explaining how alterations to the environment gave dark forms of peppered moths advantages over pale forms during the Industrial Revolution. Learning Goal Learning Outcomes

  3. Who’s Hungry?Engagement Activity • Break into teams of two • Each team should have: 2 predatory spoons, 1 black tree, 1 white tree, white moths, black moths • Put all moths on the white background. • You and your partner have 30 seconds to eat (use spoon) as many moths as you can (you may only eat one moth at a time). • NOTE – you want to eat as many moths as possible in order to survive.

  4. Discussion Questions • What did you guys notice during this activity? • What happened on the white background? • What happened on the black background? • Which color moth survived better in each environment? • These moths were each the same species, what caused the color difference? • Genetic variation • Mutation • Which genes were passed with greater frequency when the trees were white? When the trees were black?
