  1. HAPPY Monday 3/26/18 SCI SPOT: How do you think polluted environment –such as darker tree trunks affect moths living on the trees? + The-peppered-moths.STUDY

  2. 5th period Reteaching Class Rules After lunch, students need to exit the cafeteria and go directly to 6th period.  Students are expected to go to class using the shortest route.  Students are allowed to use the restroom at lunch (30 minutes), so there should not be any students late to class with the excuse given that they were in the restroom.  If students are late from lunch, please be sure that you are recording the tardies and making contact with parents, assigning detentions, and if needed, writing referrals. Also, please stand at your doors for supervision as students enter your classroom.  Once a student enters the classroom from lunch, please do not allow them to leave to the bathroom or the water fountain.  If students are not complying, please let me know and I will speak to them individually.  Dr. Sherry D. Pough 8th Grade & ESE Assistant Principal Galaxy Middle School 386-575-4144 Ext. 44412

  3. Video Topic: Rapid Adaptation Peppered Moth 1. Question: Define how natural selection acted on Peppered Moths in England. 2. Summarize in your own word process of natural selection (includes Adaptation)

  4. Class Discussion • Why did whiter peppered moth change into black one? • Why do you think black peppered moth could change back into white? After completed we will watch video about Peppered Moths.

  7. WEEK 31: 3/26-3/30 2018 HOMEWORK- Chapter 11

  8. HAPPY Tuesday 3/27/18 SCI SPOT: How can change in an environment affect species? P 392 Pocket Mice Habitat Change BE PREPARED: Pick up Textbook/ISN Have PEN/Pencil Be on Task at Bell Today: Beak Lab Day 1

  9. Video Topic: Pocket Mice Habitat Change Question: Why majority of all mice had dark colored fur instead of light colored fur. (Please explain what happened in the video in your own words.)

  10. HAPPY Wednesday 3/28/18 SCI SPOT: Imagine there are two types of hamsters living on an island winged and wingless, what type of event would make one species better adapted to the change than the other? +Handout Have PEN/Pencil Be on Task at Bell http://misskraemerscience.weebly.com/

  11. Video Notes Topic: Natural Selection 3/28 • What is “Fitness” of • organism. • 2. What is Adaptation? • 3. What are homologous • Structures?

  12. Checking Understanding Adaptation

  13. Grading Handouts-Natural Selection Sign both names on handout (work with your shoulder partner quietly) Complete all questions and graph on page 1+2 read text questions carefully please! ___________________________________________ Voice Level-1 low whisper talk to partner ONLY Movement NONE-Leaving Class NO, work on your graded handouts. Help-RYH

  14. 1. Overproduction=cacti grow more leaves and store more water than they can use, this is to ensure that if parts of the plants get eaten there is still enough for the plant to survive or to have enough water when the roots can’t get it-in drought.

  15. 2. Genetic Variation=cacti plants are displaying variations=one has thorns one doesn’t.

  16. 3. Selection (Struggle to Survive)=cacti plants with the thorns are more protected from deer as they deter deer from eating them. (deer is more likely to eat the cactus that doesn’t have thorns)

  17. 4. Competition (Survival of the Fittest)= since the cacti without the thorns gets eaten more and more, there is not enough of the plants to survive and reproduce.

  18. 5. How Natural Selction acted on the cacti= see the last photo (4) here we see that all the surviving cacti have thorns this is because this plant was better adopted to survive and not be eaten by deer.

  29. New Learning Goal: Understand, than simulate (model-lab), the effects of natural selection on genetic variation with specific environmental factors such as: Food sources, climate change, predators, geography;

  30. QUIZ QUIZ TRADEEvolution Vocab Handout • 1.FIND DEFINITIONS IN YOUR BOOK/ISN (Start on 374) • 2. WRITE DEFINITIONS ON THE BACK OF AN INDEX CARD-MAKE 4 CARDS-ONE FOR EACH:1.Adaptation, 2. Biodiversity, 3. Endangered Species, 4. Evolution • 3. STAND UP, HAND UP, PAIR UP: QUESTION-QUIZ AT LEAST 2 STUDENTS ON EACH TERMINOLOGY ABOVE. TAKE TURNS.

  31. Chapter 11: Scavenger Hunt: 7MIN • Scavenger Word Hunt: Look through Lesson 11 and find answers to 1-4, and write them in your ISN. 1. How many species scientists have identified existing on Earth? 2. What were main differences between iguanas on the Galapagos Islands and on the mainland? 3. How do Endangered species differ from Threatened Species?Endangered-vs-threatened-species Study

  32. Darwin Hypothesized that species change over many generations and become better adapted to new conditions. Darwin proposed that over a long time natural selection can lead to change. Helpful variations may accumulate in species and unfavorable disappear. Charles DarwinCLASS NOTES

  33. WHAT DOES THIS DIAGRAM SHOW?

  34. Homologous Structures • Homologous Structures-SIMILAR structures that related species have inherited from common ancestor and also have different mature forms in different organisms, but develop from the same embryonic tissue. (Turn to page 383 and look at figure 4)

  35. Other Evidence for Evolution • Vestigial organs-organs that serve no useful function in an organism • i.e.) appendix, miniature legs, arms Bird Brain Evolution

  36. THINK/PAIR/SHARE RULES: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND, THEN COME TO MY DESK ONE AT A TIME PHONES: NO TIMER: 8 MIN • 1. What is main difference between a “Hypothesis” and Scientific Theory? (Pages 385/388) • 2. Sexual reproduction causes variation in species. How does this affect survival of species? • 3. What role “adaptation” plays in “natural selection”? (page 390)

  37. ANSWERS VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND, THEN COME TO MY DESK ONE AT A TIME PHONES: NO TIMER: 8 MIN • 1. Both hypothesis and scientific theory are based on observation but scientific theory is based on tested and verified hypothesis. (Pages 385/388) • 2. Species that has no variation might eventually become extinct. • 3. Adaptation to environment is a factor that affects survival likelihood of species. (page 390)

  38. Graded Partner Work Lab: Adaptation & Natural Selection Procedures: During Partner Work: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND PHONES: NO • Sign both of your names on the handout; • Read handout together with your shoulder mate, then take turns giving examples -3 example each student –total 6 animal examples. • Highlight the definition of Adaptation and copy it in your ISN.

  39. TURN TO SHOULDER PARNER TAKE TURNS: 1. In your own words, describe what YOU think NATURAL SELECTION means…

  40. Class Notes: Natural Selection • Over time, natural selection results in changes in inherited characteristics of a population. These changes increase a species fitness in its environment.

  41. Three Video Facts: Exit Ticket Safari Montage Natural Selection2. Watch the video and write 3 new things you have now learned. NOTE: You will be required to show your 3 facts completed in ISN to teacher when the ISN is collected at the end of the class;

  46. Answers Review 1. Scientific Theory/Scientific Law: A scientific theory is a well-supported testable explanation of phenomena that have occurred in the natural world. (why it happens) Scientific Law predicts that phenomena will occur. (what will happen each time) 2. Three Resources for survival: food, water/shelter (safety) 3. Florida Panthers: Q1: leading cause of death: hit by cars; what would be # of panthers killed by other panthers if total population is 1120? (21%); Q2: Reduce # of death: better adopted-new traits crossbreeding: Lower Diseases 3/28 MON 1.A new species from parts of it becomming isolated from the rest for a very long time resulting them to evolve different traits. 2. Crickets-Discuss 3. Review Answers Darwin Handout

  47. Evidence of Evolution • The Fossil Record • Geographic Distribution of Living Things-similar environments have similar types of organisms • Homologous Body Structures • Similarities in Early Development

  48. Food for Thought Earth has millions of other kinds of organisms of every imaginable shape, size, and habitat. This variety of living things is called biological diversity. How did all these different organisms arise? • Review what is genetic Variation? TURN TO YOUR SHOULDER PARTNER AND DISCUSS FOR TWO MINUTES QUESTION BELOW:

  49. Darwin’s Theory of Evolution • Evolution, or change over time, is the process by which modern organisms have descended from ancient organisms. • Blue Book Page: 637 1. Natural selection of Insecticide Resistance: Read figure 2 and in your own words explain to your shoulder mate your understanding. 2. In ISN write in your own words what Insecticide Resistance is.

  50. Turn To Shoulder partner and discuss, take turns: How do you think Darwin came up with his theory?
