I stumbled upon these free simulations from ASU while looking for another activity I had used in the past. I am so glad!
The simulation demonstrates how natural selection leads to the evolution of peppered moths. Students can choose to have a light-colored or dark-colored tree. They take on the role of birds hunting for the moths. The simulation has a timer and graphs the outcomes of the moths the students find.
It is simple and easy to use and requires no prep work. I would use it alongside a worksheet, or have students generate questions to kickoff a unit on evolution.
