Ann Brokaw presents three BioInteractive resources she uses to support the short film "Natural Selection and Adaptation. Activity for Natural Selection and Adaptation. As students work through the questions, teachers should monitor and use questioning as needed to make sure that students use reasoning to synthesize the evidence from the illustrations and short film to construct an explanation about how natural selection provides a mechanism for the rock pocket mouse populations to adapt to the change in their environment due to dark lava flow. Developing an Explanation for Mouse Fur Color. Students will form a hypothesis to explain how a change in amino acid sequence affects the functionality of the MC1R protein, and how that change might directly affect the coat color of the rock pocket mouse populations. This resource is explicitly designed to build towards this disciplinary core idea. This resource is explicitly designed to build towards this performance expectation. Throughout the activity, students should work with a partner or in small groups and be encouraged to share their thinking as they make decisions about re-ordering their illustrations, graphing the data, and answering the questions.

    This film uses the rock pocket mouse as a living example of Describe what a mutation is and how it may affect an individual's survival and. This film describes natural selection and adaptation in populations of rock pocket mice living.

    This animation shows how quickly an advantageous mutation can spread through a mouse population over multiple generations. Mutations with even a small.
    Activity for Natural Selection and Adaptation. This can naturally lead from students constructing written arguments to presenting oral arguments which in turn can lead to counter-arguments.

    Color Variation Over Time in Rock Pocket Mouse Populations

    Comments about Including the Disciplinary Core Idea Teachers should remind students to use evidence from the rock pocket mouse population illustrations and the short film and animation as they work through four open-ended questions about the change of rock pocket mouse populations over time. Watching the short film, students learn about the changes of rock pocket mouse populations, and that the environment contributes towards determining whether or not randomly arising mutations in fur color are advantageous, neutral, or deleterious.

    Activity 1 is a basic version of the activity appropriate for first-year high school biology students. It covers the same content as Activity 1, but also includes concepts of protein structure, protein domains, and how the mutation location can affect phenotypic expression. Analyze and organize data.

    This resource is explicitly designed to build towards this science and engineering practice. Crosscutting Concepts.

    Interactive Questions for Natural Selection and Adaptation

    Before starting the activity, it is helpful if the teacher familiarizes students with the rock pocket mouse and its habitat. Traits that support successful survival and reproduction in the new environment become more common; those that do not become less common. View Article. Mismatch Repair.

    Activity for Natural Selection and Adaptation

    Developing an Explanation for Mouse Fur Color.

    This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest. Mice living on light-colored sand tend to. This ten minute film shows adaptive changes in rock pocket mouse populations.

    mutation (in this instance dark fur) through the population of rock pocket mice.

    Justify your answer in one or two sentences: "The same mutation could be As you saw in the film, rock pocket mice evolved to have dark-colored fur in certain.
    The teacher can use probing questions about the data students collected and analyzed from the illustrations and the information from the short film, to make sure that students construct their argument based on evidence from their data table and graph, and the information from the short film.

    Science and Engineering Practices. Sickle Cell Disease. The animation and the short film also show the competitive advantage of a coat color allowing an individual mouse to blend into the background to avoid predators.

    How does that connect to what you learned from the short film? Students are being asked to identify the change in the number of light and dark rock pocket mice as the color of the substrate changes from light to dark due to dark lava flow at location B.

    In these activities, students transcribe and translate portions of the rock pocket mouse Mc1r gene to further explore the genetic variations responsible for different coat colors as described in the short film Making of the Fittest: Natural Selection and Adaptation. Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions.

    The teacher can use probing questions about the data students collected and analyzed from the illustrations and the information from the short film, to make sure that students construct their argument based on evidence from their data table and graph, and the information from the short film.

    Mutation in Rock Pocket Mice.

    Background. A mutation is a permanent change in an organism's DNA. Most mutations originate as copying.

    Molecular Genetics of Color Mutations in Rock Pocket Mice

    In addition, the dark mouse population contains the mutant Mc1r gene, which results in a In the film, Dr. Sean Carroll says that mutations occur randomly. Use the example of rock pocket mice to explain why this statement is not true.

    In your.
    How does that connect to what you learned from the short film? Before starting the activity, it is helpful if the teacher familiarizes students with the rock pocket mouse and its habitat. Students are being asked to identify the change in the number of light and dark rock pocket mice as the color of the substrate changes from light to dark due to dark lava flow at location B.

    Comments about Including the Science and Engineering Practice Part of the activity asks students to write a scientific summary that describes changes in the rock pocket mouse populations at the location that changed from light to dark substrate due to a dark lava flow location B. Through skillful questioning teachers can make sure that students realize that mutations are random, that variations of traits fur color in this case occur normally in populations, and that a change in environmental conditions the color of the ground provides a selective advantage to those individuals already possessing these traits.

    Based on what they learned from the short film, students order the four illustrations from oldest to most recent. It covers the same content as Activity 1, but also includes concepts of protein structure, protein domains, and how the mutation location can affect phenotypic expression.

    Traits that support successful survival and reproduction in the new environment become more common; those that do not become less common.

    The short film explains that mutations can cause a change in coat color, and that these genetic changes are being passed on to offspring. Coding Sequences in DNA. Before starting the activity, it is helpful if the teacher familiarizes students with the rock pocket mouse and its habitat.

    Based on this evidence, and what they learn about variation and natural selection in the accompanying short film, students use this evidence to explain the change in the rock pocket mouse populations on the lava flow dark substrate over time.
