Big Beans, Little Beans
Grade Level(s):
- 6-8
Source:
- UC Museum of Paleontology
Resource type:
- Classroom activity
Time: Variable
Overview
Students measure and note the variation in the lengths of lima beans. Students then compare the growth rate of different sized beans.
Born to Run: Artificial Selection Lab
Grade Level(s):
- 6-8
Source:
- Garland, Theodore
Resource type:
- Classroom activity
Time: Four 45-minute periods
Overview
Students are introduced to the field of experimental evolution by evaluating skeletal changes in mice that have been artificially selected over many generations for the behavioral trait of voluntary exercise wheel running.
Clipbirds

- UC Museum of Paleontology
Resource type:
- Classroom activity
Time: One class period
Overview
Students learn about variation, reproductive isolation, natural selection, and adaptation through this version of the bird beak activity.

Time: 10 minutes
Overview
This 10-minute film describes the research of Dr. Michael Nachman and colleagues, whose work in the field and in the lab has documented and quantified physical and genetic evolutionary changes in rock pocket mouse populations.
The Making of the Fittest: The Birth and Death of Genes
Grade Level(s):

- 13-16
- Student
Source:
- Howard Hughes Medical Institute
Resource type:
- Video
Time: 15-20 minutes
Overview
This 13-minute film describes how scientists have pieced together the evolutionary history of the Antarctic icefish by studying its genome – an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.
