Film Guides: Evolving Switches, Evolving Bodies

Summary

These classroom-ready resources complement the short film Evolving Switches, Evolving Bodies, which tells the story of the dramatic transformation of stickleback fish as they adapted to living in freshwater habitats drastically different from the ocean.

Note: The guides and quiz were revised October 1, 2014 to incorporate field-testers' comments. The In-Depth-Guide was also revised to include film pause points and discussion questions.

These guides and quiz support the short film Evolving Switches, Evolving Bodies. The “At a Glance Film Guide” provides a short summary of the film, along with key concepts and ties to selected curricula and textbooks. The “In-Depth Film Guide for Teachers” includes a more detailed summary and background information, discussion points, lists of related resources and references, and answers to the accompanying student “Quiz.” The "Quiz" is designed as a summative assessment that probes student understanding of the key concepts addressed in the film. These documents are updated as new information and resources become available.

Short Film
After the end of the last ice age 10,000 years ago, populations of marine stickleback fish became stranded in freshwater lakes dotted throughout the Northern Hemisphere in places of natural beauty like Alaska and British Columbia. These remarkable little fish have adapted and thrive, living permanently in a freshwater environment drastically different than the ocean.
Classroom Resource
A hands-on activity in which students analyze the results of genetic crosses between stickleback fish with different traits.
Classroom Resource
A hands-on activity in which students interpret molecular diagrams and build physical models of eukaryotic gene regulation.
Classroom Resource
A worksheet that guides students through The Stickleback Evolution Virtual Lab. The virtual lab lets students learn firsthand the methods for analyzing body structure in stickleback collected from lakes and fossils recovered from a quarry. Students measure, record, and graph their results to discover evolutionary patterns.
Virtual Lab
This virtual lab teaches skills of data collection and analysis to study evolutionary processes using stickleback fish and fossil specimens.
