Finally, students complete a VIDA chart (variation, inheritance, differential survival, adaptation) to EXPLAIN why elephants in Mozambique lost their tusks. This activity provides an introduction to natural selection and the role of genetic variation by asking students to analyze illustrations of rock pocket. The overall anchoring phenomenon focuses on things that make you sick, each unit will feature a story. Curriculum is NGSS aligned and uses anchoring phenomenon. Page includes links to presentation slides, guided notes, handouts, and experiments. This animation uses equations from population genetics to simulate how quickly a new, advantageous fur color spreads through a rock pocket mouse population. Students answer questions as they watch the film to keep them on task. Rock Pocket Mice 3.5 (4 reviews) Term 1 / 6 Why did dark-colored mice first appear in a populations of light-colored rock pocket mice Click the card to flip Definition 1 / 6 They have a genetic mutation that affects their fur color. This is a semester long course for vocational track students. I also put up a map of the world because many of my students need a geography reminder about where Africa is and how large it is.Īfter the discussion, students watch the HHMI film “Selection for Tuskless Elephants” which is about 7 minutes long. The first page of the lesson is a good time to have a discussion about what efforts humans should make to protect animals. Information on this section of reading was summarized from The Great Elephant Census site. The activity starts with a history lesson on the ivory trade and poaching. The elephants studied at Gorongosa National Park show that females in a certain age group have a high frequency of tusklessness. Divide students into pairs, and provide each pair with a sheet of white paper. Students had been studying evolution, looking at many HHMI resources like the “ Rock Pocket Mouse” and Finches on the Galapagos. How might we investigate rock pocket mice to help answer this question. In picture 1,3, and 4, it is very similar. ANSWER KEY ACTIVITY 1 GENE TABLE 1: WILD-TYPE MC1R GENE (LIGHT COAT-COLOR. Rock Pocket Mouse play as a pray in a desert food web What explains the differences among the four illustrations Is there anything that confirms or contradicts the order in which you arranged the illustrations They are in different locations. This activity was created for an evolution unit in an intro biology class (1 semester class) where I wanted to include a little bit of ecology and conservation science. TO THE MOLECULAR GENETICS OF THE COLOR MUTATIONS IN ROCK POCKET MICE.
