Each image shows the color variation attwo. Pocket Mouse : Series Pocket Mouse : Item model number PM-1000 : Hardware Platform Laptop, Tablet : Operating System Windows 8.
Throughout the activity, students learn concepts such as fitness, natural selection, mutation, and phenotype. Watch this video before you begin: PROCEDUREThe pictures represent snapshots of rock pocket mouse populations. Students then watch the HHMI Video on pocket mice and answer discussion questions. Students also graph the color differences at each location to show how the dark variation increased over time in response to an environmental change. The silky pocket mouse is a small, delicate mammal that can be distinguished from other rodents by: 1) light yellowish to reddish-buff pelage intermixed with black hairs, 2) conspicuous pale yellowish patch of hair behind each ear that is at least twice the length of the ear, 3) soft, long, silky hair, 4) purer white underparts, 5) tail. (Cards can be printed and laminated for multiple uses.) Students collect data on the number of mice phenotypes in each location and develop a hypothesis about the order of the cards. Despite its slightly awkward looks, the sub-300 Diamondback DB9 is just 4-inches high and weighs 13.4-ounces, which puts it and the Kel-Tec PF-9 in the same club of being about the only pocketable 9mm pistols on the concealed carry market. Sonoran Desert species: little pocket mouse (Perognathus.
Students look at cards showing light and dark mice on different substrates. In this way many species of heteromyid mice and rats can share the same environment. It is found in Arizona, California, Nevada and Utah in the United States and Baja California in Mexico. It has been simplified from the original activity so that it is suitable for beginner biology students. The long-tailed pocket mouse ( Chaetodipus formosus) is a species of rodent in the family Heteromyidae. This worksheet was modified from the HHMI Activity on color variation in the rock pocket mouse.
