Evolution – VIDA chart
This chart is used as a graphic organizer to help students understand the process of evolution by natural selection. I use this chart multiple times throughout the unit, basically for each model organism we study. VIDA means: Variation, Inheritance, Differential Survival and Reproduction, Adaptation. These principles apply not matter what organism you are studying. For…

Case Study: How Did the Guppy Get His Color?
This case study examines evolution in guppies as evidenced by color variation in populations. It is based on an iconic study performed by John Endler where he collected data on guppies by scoring the size, number, and brightness of spots. Students progress though the slides (lecture and discussion), and examine details of Endler’s study, such as where…
