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. (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. Explain how the environment plays a role in changing the frequency of a mutant allele in a.
appearance of dark colored volcanic rock caused the mutation for black fur to appear in. LESSON The Making of the Fittest: Natural Selection and Adaptation COLOR VARIATION OVER TIME IN ROCK POCKET MOUSE POPULATIONS INTRODUCTION A typical rock pocket mouse is about 170 millimeters long from its nose to the end of its tail, shorter than an average pencil. Students look at cards showing light and dark mice on different substrates. Is the following statement true or false Justify your answer in one or two sentences: The. It has been simplified from the original activity so that it is suitable for beginner biology students. Discuss how understanding the structure of DNA is essential to understand the molecular mechanism of what is going on with the coloration of the rock pocket mice. Suppose COOane studying _ recently discovered populzion of rock pocket mice Kth volcanic rock You take a DNA dark-colored sample from member cithks " that lives on qeneKown play new population and determine the DNA fur color.This worksheet was modified from the HHMI Activity on color variation in the rock pocket mouse. Biology questions and answers there is a 10 minute short video to watch: Natural Selection and the Rocket Pocket Mouse on YouTube. Your summary should include a description of how the.
I don’t make answer keys easily available because my students wil take shortcuts.

Write yes" There bt more Ihan Yes , "selection" (or "selective and "evolution" (or "evolve 2). Write a scientific summary that describes changes in the rock pocket mouse populations at location B. The answer key is available at HHMI for free, though I did modify the lesson. Rock Pocket Mouse Activity Essential Question: How does a physical characteristic of a population change over time Examine the population of rock pocket mice populations over time. Suppose COOane studying recently discovered populzion of rock pocket mice Kth volcanic rock You take a DNA dark-colored sample from member cithks " that lives on qeneKown play new population and determine the DNA fur color. Color Variation Over Time in Rock Pocket Mouse Populations. Sean Carroll states that "whlle mutation owntords random natural selection explain how this not" In your possible: SOLVED: Asyou saw inthe film rock pocket mice evolved to have dark-colored fur in certain habitats In three to five sentences, explain how this trait increased frequency in the population Include the following key terms: "fitness" (or "fit ) 'survival" (or "survive ], "selection" (or "selective and "evolution" (or "evolve 2).
