Session 5- Variation, Adaptation, and Natural Selection

Supplements to CTS: Section I- Scientists explain the role of DNA and genes as a source of variation and mutation is introduced as one cause of new variations in populations. Dr. Paul Williams describes his experience observing variation and how he developed Fast Plants through artificial selection. The historical contributions and focus of Darwin on the meaning of adaptation through natural selection are highlighted. Section II- A 6th grade class is shown investigating variation in plant height.

Concept Cartoons- Variation

Several of the concept cartoon assessments on this site can be used with Section IV to elicit student ideas related to variation and compare the ideas your students have with common ideas that emerge from the CTS study. Commentary that accompanies each cartoon describes common misconceptions noted in the research literature.
