Selection in action - Peppered moths
This online resource is a lesson plan for a practical activity or demonstration that also provides detailed teaching notes and a student worksheet.
The purpose of the lesson is:
- to review information about the peppered moth (Biston betularia), its two main colour forms and the places in which they are found; and
- to analyse and evaluate evidence for natural selection.
This activity has been produced by the Nuffield foundation in partnership with the Society of Biology (UK) and is found on the Nuffield foundation website.
Some of the terminology and questions may be challenging for students. The worksheet is a Word document which enables the activity to be adapted to ability of the class.
A slide show of peppered moth images that can be used by teachers in their lessons can be found at www.arkive.org/peppered-moth/biston-betularia/. A Google search can find others.
