Natural Selection Experiment

Avg. Ratings: 2.0 (1 Review)
91-A 91
Students duplicate the famous peppered moth evolution study in the lab with this Natural Selection Experiment.

  • Students Simulate Predator-Prey Relationship
  • Reusable
  • Time Required: One 50 Minute Class Period
  • Teacher's Instructions Included
  • Two Lab Activities Included
In the 1950s, Oxford University scientist Dr. Bernard Kettlewell studied the changes in England's peppered moth population. Over a hundred-year period, the population of peppered moths shifted from being primarily light-colored to dark-colored. Dr. Kettlewell reasoned that predatory birds fed on more light-colored moths because they were more easy to spot against the pollution-darkened tree bark. This meant that the dark-colored moths survived in greater numbers, and the genes for their dark coloring were passed down to future generations.

Using Dr. Kettlewell's study as the basis for experimentation, students conduct two simple quantitative lab activities that demonstrate the effects of environmental pollution on nature.

Ordering information: This experiment includes a teacher’s guide, student data charts, environmental trays (black), environmental trays (brown), re-sealable bags, moths (simulated), and squares.

Group size is too big - I have not tried this activity yet but it seems good. The problem I see is that when they say it is good for a class of 30 they assume 5 students per group. After reviewing the activity I only see two jobs per group, therefore it would be appropriate for partners, not groups of 5. I feel this was misleading and now have to struggle with making this work in my large classes.
