This is a great activity for introducing or reviewing the process of Natural Selection along with some examples (Peppered Moths, Vampire Bats, CoHo Salmon, Shore Crabs, Birds of Paradise, and Greyhound dogs).
Pairs of students work through two rounds of “The Pit Game”. During the first round they are given an envelope with mixed-up strips of paper, each with a step of natural selection. They have to figure out which strips they need and which they can trade in the “pit”. Their goal is to have a complete set of steps of Natural Selection.
In the second round, each pair is given an envelope representing an example of Natural Selection in action. Their strips of paper are mixed with other examples. Working together, they have to figure out which strips they need and which they can get rid of. They negotiate in the “pit” until hey have a complete set for their example.
The strips include the basic steps of natural selection and those steps in the context of each example. Each example also has a graph showing the type of selection (directional, stabilizing, and disruptive). There are seven specific examples and clear instructions for setting up this game.
I use this game for my IB HL Biology students, so many of the examples are from the IB syllabus. It would be appropriate for any level of biology, including AP Biology.
