![]() The “Card Images” ZIP file contains individual image files for the cards used in this activity that can be used in the classroom, particularly in online courses. This activity serves as an extension to the short film The Making of the Fittest: Natural Selection and Adaptation and as a means of reinforcing the concepts of variation and natural selection. The activity involves collecting and graphing data and making evidence-based claims. ![]() They then order those images based on the data and their knowledge of evolution by natural selection. Students analyze data from images of rock pocket mouse populations in different settings and over time. The film is also available as an interactive video with embedded questions, which test students’ understanding as they watch the film.This activity allows students to collect and analyze data on the evolution of coat color in rock pocket mouse populations living on differently colored substrates. If your class covers Hardy-Weinberg equilibrium, The short film explains that mutations can cause a change in coat color, and that these genetic changes are being passed on to offspring. You can find populations of rock pocket mice all over the … Genetics revealed what surprising fact about mice in different locations? Animals develop many types of defenses to avoid being eaten. As they are completing the data table and creating a graph, students use the mathematical representations they created to identity patterns of light/dark fur color in the rock pocket mouse populations on the light and dark background over time, which they cite as empirical evidence to support their explanation, making the crosscutting concept of patterns an integral part of the learning experience. Light-colored mice had a selective advantage because Why would coat color influence the chance of a rock pocket mouse to survive and reproduce on a dark or light substrate?” Different ways to help students monitor their own learning include encouraging students to explain their thinking to each other when working in small groups, defending their answers to the large group, writing and sharing their answers on white boards, large post-it notes, or using an Elmo. Your summary shouldOriginally, location B had a sandy-colored soil. ![]() Use colored pencils to make a BAR GRAPH showing the numbers and colors of mice at each location1. (Cards can be printed and laminated for multiple uses.) Be sure to provide an appropriate title for the graph, and titles and labels for the x- The activity is a paper and pencil activity, and students can create the graphs using colored pencils. An incorrect response results in an explanation of why the answer is not correct and the invitation to try again. The coat colour is very important as it is an important mean of camouflage for the mouse and having the same colour of fur as it's environment increases its chance of livingWhy were there dark mouse in lighter environment? The rock pocket mouse is an excellent model organism to study geographic variation in phenotype within a single species. The short film, with many vivid visuals, reinforces the disciplinary core idea and adds the lens of the nature of science. You can find populations of rock pocket mice all over the … Such probing questions could include: “What is your data table and graph telling you about the number of light colored and dark colored rock pocket mice over time at location B? There are no suggestions on how to connect instruction to students’ home, neighborhood, community, and/or culture. 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. Introduction: A typical rock pocket mouse is about 170 millimeters long from nose to rump, shorter than an average pencil. And at just 15 grams, this tiny mouse weighs about as much as a handful of paper clips. Teachers could find examples of similar phenomena in local ecosystems on their own. over-time-rock-pocket-mouse-populations). Suggest a reason why light skin may be an advantage for people living in other regions.3. Based on what they learned from the short film, students order the four illustrations from oldest to most recent. After having completed the graphs, students use the mathematical representations they created to identify patterns of light/dark fur color in the rock pocket mouse populations on the light and dark background over time. This is an important tip, as it provides an opportunity to reveal students’ prior knowledge. COLOR VARIATION OVER TIME IN ROCK POCKET MOUSE POPULATIONS INTRODUCTION The tiny rock pocket mouse weighs just 15 grams, about as much as a handful of paperclips.
