  1. HAPPY Monday 3/19/18 SCI SPOT: Explain in your words how mutation affects diversity in species, what is mutation? (you can use your phone to look it up) Mutation-TWIG BE PREPARED: Pick up Textbook/ISN Have PEN/Pencil Be on Task at Bell

  2. Mutation Change in DNA sequence-producing new CHARACTERISTICS OR TRAITS THAT CAN BE INHERITED.

  3. WEEK 29: 3/19-3/23 2018 HOMEWORK- Revisit all Chapter 11 Pages 374-400

  4. MUTATION SONG+ HANDOUT There 7 questions –listen carefully to the words and complete your handout. Mutation song Mr. Parr

  5. 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;

  6. Poster Project or PPT presentation Due this Wednesday. 3/21/18 (Was Assigned 3/5/18) 20 Points 20 Points 20 Points 20 Points 20 Points

  7. HAPPY Tuesday 3/20/18 SCI SPOT: Explain WHY environmental change can affect an organism’s ability to survive? P.392 BE PREPARED: Pick up Textbook/ISN Have PEN/Pencil Be on Task at Bell

  8. Sci Spot Tuesday 3/20/18 Video Notes Topic: Origin-of-Species Change in environment can affect an organism’s ability to survive and therefore lead to natural selection. Genetic vatiation (favorable mutations will allow adaptations to changes in an environment- example: Monkey Flowers.

  9. Read Page 393 then answer in your ISN. Environmental Change When copper contaminated the soil surrounding the monkey flowers, the environment changed. What do you think the area will look like in ten years? TURN TO PAGE 393

  10. Video Notes Tuesday 3/20/18 Video Notes Topic: Origin-of-Species How can environmental change affect an ability of an organism to survive?

  11. Quiz Tuesday 3/20/18 Video Notes Topic: Origin-of-Species Absolute Silence (you will get 0 if you talk) Movement: not allowed /no tapping and no noise making

  12. ALL WRITE CONSENSUS USING HANDOUT “Adaptation” What to do: 1. We will read the probe as a class together. 2. Think Time: 2 min to share your ideas with your group 3. You will have total of 8 min (2 min for each student) to write justifications for their answers using different color markers. Students will agree or disagree with 3 possible answers and explain and defend their ideas-using this strategy-"All Writes Consensus"

  13. HAPPY Wednesday 3/21/18 SCI SPOT: What evidence supports evolution? (recall videos we watched + look at pages 380/381) Today: Posters are due! BE PREPARED: Pick up Textbook/ISN Have PEN/Pencil Be on Task at Bell http://misskraemerscience.weebly.com/

  14. Answers FIRST READ PAGE 382 Example: Both bird’s wing and dolphin’s flipper have same bones in somewhat different shapes, look at page 382-which bones are the same? • 1. Evidence: 1. Fossils, 2. similar DNA, 3. Similar body structures =homologous structures. • Note that when: Similar bones are pointing to a common ancestor scientists must confirm DNA too to prove that they are related. (Also Darwin did not know about DNA-wasn’t discovered yet!

  15. Video Notes:Topic: Evidence EvolutionDate: 3/21/18 Evolution-Evidence Provide at least 3 types of Evidence of Evolution.

  16. Evidence of Evolution IN HOMOLOGOUS STRUCTURES (TURN TO PAGE 382) TO DO: Complete “Homologous Structures Handout” and COLOR the bones that are same in Bat and Bird see examples below. Homologous Structures The bones in a bird’s wing, a dolphin’s flipper, and a dog’s leg have similar structures. Which bones in the dog's leg match those in the flipper and which match those in the wing? 1. First come to the board to color in the wing and the flipper.

  17. 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

  18. OLWEUS CLASS 2 1. RAISE HAND WHEN YOU WANT TO SPEAK 2. EVERYONE HAS RIGHT TO BE HEARD. 3. WE LET OTHERS SPEAK=NO INTERRUPTING. 4. EVERYONE HAS A RIGHT TO PASS. 5. WE CAN DISAGREE WITHOUT SAYING MEAN THINGS. 6. WHEN TALKING ABOUT BULLYING WE DON’T MENTION NAMES!!! BUT DO REPORT!

  19. HAPPY Thursday 3/22/18 SCI SPOT: What are homologous structures?” p382 Give definition plus fill out the “ Homologous Structures handout” BE PREPARED: Pick up Textbook/ISN Have PEN/Pencil Be on Task at Bell Today is Reading Check Quiz http://misskraemerscience.weebly.com/

  20. 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)

  21. READING CHECK QUIZ ABSOLUTE SILENCE NO MOVEMENT STAY AT SEAT NO NOISE OR TAPPING NO TURNING AROUND WHEN DONE TURN TEST OVER AND WAIT SILENTLY

  22. READING CHECK QUIZWEEK 29: 374-400 1. TRUE OR FALSE? Scientific theory is well supported and widely accepted explanation from nature that is subject to change as new evidence is discovered. 2. TRUE OR FALSE? New species can form when a group of individuals remains reproducing in the same habitat not isolated from other group members.

  23. Pm: READING CHECK QUIZWEEK 29: 374-400 1. TRUE OR FALSE? New species can form when a group of individuals remains reproducing in the same habitat not isolated from other group members. 1. TRUE OR FALSE? Scientific theory is well supported and widely accepted explanation from nature that is subject to change as new evidence is discovered.

  35. 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

  45. 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.
