![]() ![]() This activity provides an introduction to natural selection and the role of genetic variation by asking students to analyze illustrations of rock pocket mouse populations (dark/light fur) on different color substrates in the Sonoran Desert (light/dark) over time. A slide presentation as well as a student worksheet with instructions and questions are provided. Students gain practice and perspective on making evidence-based decisions. Student pairs confer with other teams, conduct Internet research on specific storms and conclude by presenting their recommendations to the class. Then they put their knowledge to work by using the GIS software to explore historical severe storm (tornado, hurricane) data in depth. A link to Rosemary and Peter Grants research on finch populations in the Galapagos is identified for those teachers who want to connect the simulation to a real life example.Īs if they are environmental engineers, student pairs are challenged to use Google Earth Pro (free) GIS software to view and examine past data on hurricanes and tornados in order to (hypothetically) advise their state government on how to proceed with its next-year budget-to answer the question: should we reduce funding for natural disaster relief? To do this, students learn about maps, geographic information systems (GIS) and the global positioning system (GPS), and how they are used to deepen the way maps are used to examine and analyze data. Four years pass during the simulation and students are asked to describe what happened to the Clipbird populations and what they think caused the changes. The big billed birds need to eat more than the medium and small billed birds to survive and each bird needs to eat more than the minimum amount of food for survival to be able to reproduce. Food is spread out for the birds to eat and then after 15 seconds it is counted to see whether birds have gathered enough food to survive. Popcorn, lima beans and marbles are the three types of food available in the two areas. The birds with binder clip beaks live in Clipland where the large population becomes divided into two smaller populations by a mountain range. This variation on the classic bird beak activity demonstrates variation of beak size within a population and shows how the proportion of big-, medium-, and small-beaked birds changes in response to the available types of food.
