Activity Introduction

lizard-heroQuick summary: In this lesson, students explore the idea of speciation and the factors influencing speciation. They begin by participating in a class discussion around key concepts relating to speciation, and then work in pairs to complete an activity deciding what types of habitats two species of monkey would be suited to based on their physical characteristics. Finally, students are asked to create a clay-mation video showing the steps by which two different species of lizard could develop from one species after the formation of the desert of the Nullarbor Plain.

Learning goals:

  • Students recognise the steps of speciation.
  • Students understand the factors affecting speciation.
  • Students understand the relationship between speciation and natural selection.
  • Students understand how to make a clay-mation animation.
