Overview
This hands-on activity, used in conjunction with a short film, teaches students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits. It
Natural selection and evolution of rock pocket mouse populations
Grade Level(s):
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: 50 minutes
Overview
This lesson serves as an extension to the Howard Hughes Medical Institute short film The Making of the Fittest: Natural Selection and Adaptation. It provides an opportunity for students to analyze amino acid data and draw conclusions about the evolution of coat-color phenotypes in the rock pocket mouse.
Molecular genetics of color mutations in rock pocket mice
Grade Level(s):
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: 50 minutes
Overview
This lesson requires students to transcribe and translate portions of the wild-type and mutant rock pocket mouse Mc1r genes and compare sequences to identify the locations and types of mutations responsible for the coat color variation described in a short film.
The Making of the Fittest: The Birth and Death of Genes
Grade Level(s):
- 6-8
- 9-12
- 13-16
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.
The Making of the Fittest: Natural Selection in Humans
Grade Level(s):
- 9-12
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Video
Time: 15-30 minutes
Overview
This 14-minute film describes the connection between the infectious parasitic disease malaria and the genetic disease sickle cell anemia - one of the best-understood examples of natural selection in humans.
The Making of the Fittest: Natural Selection and Adaption
Grade Level(s):
- 6-8
- 9-12
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Video
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.
Testing a hypothesis
Grade Level(s):
- 9-12
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: 50 minutes
Overview
Students watch a short film about natural selection in humans and answer questions on a worksheet that reinforce the evolutionary story behind malaria and sickle cell anemia prevalence.
Gene switches
Grade Level(s):
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: Two 45-minute blocks
Overview
This lesson explains how genetic switches function and their role in the process of evolution through the use of clips from the HHMI DVD, Evolution: Constant Change and Common Threads, and the construction of a model. This activity can be done as a demonstration, a student inquiry activity, or a combination of the two.
Variations in the clam species Clamys sweetus
Grade Level(s):
- 9-12
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: 3 x 45-minute sessions
Overview
This series of hands-on activities complements the HHMI DVD Evolution: Constant Change and Common Threads and has been designed to engage students in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investigation, data collection, and pattern recognition.
Color variation over time in rock pocket mouse populations
Grade Level(s):
- 9-12
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: 50 minutes
Overview
Students watch a short film and complete a worksheet and graphing exercise that reinforces the concepts of variation and natural selection.
Allele and phenotype frequencies in rock pocket mouse populations
Grade Level(s):
- 9-12
- 13-16
Source:
- Howard Hughes Medical Institute
Resource type:
- Classroom activity
Time: One or two class 50-minute periods
Overview
This video and worksheet use real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle.
