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...
A data collection and analysis lesson that examines selection for coat color in pocket mouse populations on different color substrates over time.
A lesson that uses real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle.
A lesson that 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 the film.
An advanced lesson that requires students to analyze partial DNA sequences of the Mc1r gene and identify the effects of mutations on the MC1R protein pathway.
An activity in which students analyze amino acid data and draw conclusions about the evolution of coat color phenotypes in different rock pocket mouse populations.
A simple activity that investigates the importance of antifreeze proteins to icefish survival.
An advanced lesson that describes the role of mutations in the birth and death of genes. It includes background information, examples, video clips, and animations.
A simple demonstration that uses readily-available materials to simulate how blood pumps through the circulatory system of icefish and other fish.
A dramatic demonstration that simulates how tiny ice crystals would form and grow in the blood of most fish if they ventured into the icy waters of the Antarctic.
A worksheet designed to show students how scientists make their discoveries. It provides students with background information about how Dr. Allison's work built upon the contributions made by other scientists.
A worksheet designed to actively engage students as they watch the film. Students are asked to answer questions pertaining to the information provided in the film.
A hands-on activity in which students construct models of sickle-cell hemoglobin fibers inside red blood cells to illustrate how changes in the structure of a protein can affect cell shape. Students are then asked to relate these changes to disease symptoms.
A hands-on activity that uses simulations with beads to teach students about population genetics, the Hardy-Weinberg principle, and how natural selection alters the frequency distribution of heritable traits.
A lesson that requires students to read detailed scientific passages and explain how an understanding of specific icefish adaptations might lead to a treatment or cure for human disorders, such as osteoporosis and anemia.
A hands-on activity in which students interpret molecular diagrams and build physical models of eukaryotic gene regulation.
Students interpret the results of two different tests for lactase persistence.
Students simulate a lactose tolerance test.
Students explore the effects of different diets on the evolution of an enzyme that breaks down starch.
Students explore the genetic changes associated with lactose tolerance/intolerance and how the trait is inherited in families.
Students evaluate and discuss several statements about lactose intolerance and evolution before and after watching the film.
Students are challenged to identify “fact patterns,” or patterns that emerge from a collection of different facts and observations, and draw conclusions about what they suggest.
