An activity that recreates zones of microbial activity in a glass column. To accompany the lecture series Changing Planet: Past, Present, Future.
A short article by Dr. Sean B. Carroll detailing the discoveries covered in the film The Day The Mesozoic Died.
A lesson in which students analyze the chemical data that led researchers to conclude that the K-T boundary layer contained an extraordinary concentration of iridium.
A lesson in which students read a passage and answer questions about the information presented, testing their non-fiction reading comprehension.
A worksheet in which students calculate how much iridium was released, and eventually deposited all over the Earth, by the impact of the asteroid that caused the K-T extinction.
A hands-on activity in which students see first-hand the difference in foraminifera fossils below and above the K-T boundary.
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 worksheet in which students write down the evidence that led to the discovery that an asteroid struck Earth about 66 million years ago, causing a mass extinction.
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 work through a series of questions pertaining to the genetics of sickle cell disease and its relationship to malaria. These questions will probe students' understanding of Mendelian genetics, probability, pedigree analysis, and chi-square statistics.
