Natural Selection (HS)

Activity Overview

In this lesson, students will model natural selection, providing an opportunity to make predictions about evolution in a population over a short period of time.


  • Students will know how natural selection determines the differential survival of groups of organisms.
  • Students will know why natural selection acts on the phenotype rather than the genotype of an organism.


  • natural selection
  • evolution
  • phenotype
  • genotype
  • population
  • generation

About the Lesson

Adapted from a PhETTM simulation, this lesson allows students to model natural selection, providing an opportunity to investigate the mechanisms that lead to evolutionary changes.

As a results, students will:

  • Understand natural selection as a driver of evolution.
  • Understand how populations change as a result of mutations and selection.
  • Be able to distinguish phenotype and genotype
