A Virtual Voyage of the Beagle

Author: Jenny McGuire

Overview: This lesson allows students to virtually follow along the route that Darwin took on the HMS Beagle and make similar observations. This guided activity will allow them to reach similar conclusions as those made by Darwin himself.

Lesson Concepts:

  • Selective breeding can recombine existing variation.
  • Some animals have lived in the past that do not live today.
  • Different animals are adapted to eat different foods.
  • Animals that eat similar foods may look alike even though they are not closely related to one another.

Grade Span: 8–12

Procedure:

  1. Using the overheads, review who Darwin is and where he took his famous voyage (15 min).
