This simulation shows the spread of a favorable mutation through a population of pocket mice. Even a small selective advantage can lead to a rapid evolution of the population.
This virtual lab teaches skills of data collection and analysis to study evolutionary processes using stickleback fish and fossil specimens.
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 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 lesson that uses real rock pocket mouse data collected by Dr. Michael Nachman and his colleagues to illustrate the Hardy-Weinberg principle.
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.
To accompany the lecture series Evolution: Constant Change and Common Threads.
A lesson in which students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the K-T mass extinction.
A graduate student in the Schrag lab, Mr. Laakso uses computer modeling of Earth's atmosphere to help predict changes to come.
This hands-on activity requires students to “visit” different K-T boundary sites.
Summaries and links to the data files used to create the charts in EarthViewer, including the APK file to manually install the app.
These two activities support the film The Origin of Species: The Beak of the Finch. They provide students with the opportunity to analyze data collected by Princeton University evolutionary biologists Peter and Rosemary Grant.
Topics include measures of average (mean, median, and mode), variability (range and standard deviation), uncertainty (standard error and 95% confidence interval), Chi-square analysis, student t-test, Hardy-Weinberg equation, frequency calculations, and more.
