1 For evolution by natural selection to happen, there must be: Jan. 21st DO NOW: 1. Variation 2. Heritable Traits 3. Natural Selection Copy the notes below into your notebook on the next available page:

2 Notes cont’d: Copy the definition below into your glossary Natural Selection: organisms that are better adapted to their environment are more likely to survive and reproduce; the environment “chooses” who lives and who dies.

3 ESSENTIAL QUESTION: Q. How do natural biological processes result in the development of new species? OBJECTIVES: -Watch a video about Charles Darwin. -Take two-column notes on the Finches of the Galapagos Islands.

4 Video NOVA: What Darwin Never Knew

5 2 Column Notes -You will read GALAPAGOS FINCHES: Famous Beaks -In your notebook on page, you will complete 2-column notes as outlined in the reading. -CLASS SET ALERT!!! DO NOT WRITE on the Article

6 DO NOW Date: JAN 22 ND & 23 RD Q. How do natural biological processes result in the development of new species? Describe an organism that is closely related to snakes? Explain why you believe they are related.

7 ESSENTIAL QUESTION: Q. How do natural biological processes result in the development of new species? OBJECTIVES: -Adaptations Practice. -Watch Planet Earth Videos and determine how Environmental changes will affect species.

8 Adaptive Advantages Complete the handout on your own first. Once completed, compare and discuss your answers with a partner.

9 Planet Earth We will watch 4 clips As you watch the clips fill in the information on your sheet including: -Species -Environment -Adaptations After the clip, compare your information with your group.

10 Planet Earth Once the clip is over, you will be given an environmental change. Determine which species is most likely to survive, and what adaptations must occur in that species to ensure its survival. Fill in your explanation on your sheet, and prepare to present, as a group, your predictions.

11 The Arctic Polar bears 1 Polar Bears 2

12 The Arctic Environmental change: – Global warming has cause all of the arctic ice to melt leaving open ocean where there was once hard ice to walk and hunt on.

13 African Desert Elephant vs. Lion

14 African Desert Environmental Change: – Weather patterns begin to change resulting in large amounts of rain year round.

15 Deciduous Forest Wasps

16 Deciduous Forest Environmental Change Drought causes the trees to produce far less acorns, and the ones that are produced are half the size.

17 Antarctic Fur Seals and Penguins

18 Antarctic Environmental Change: There is no change. Discuss what adaptations could occur if the environment stays the same.

19 Presentation Expectations Presenters: – Speak clearly and loudly Audience -Listen Quietly -Decide whether you agree or disagree -When presentation is over, you may be called upon to share your thoughts

20 DO-NOW On your Do Now Sheet, match the vocabulary word to the correct example.. 1. Adaptation 2. Population3. Variation Picture B Picture C Picture A JAN 24THJAN 24TH

21 ESSENTIAL QUESTION: Q. How do natural biological processes result in the development of new species? OBJECTIVES: -Adaptations Practice. - Understanding how natural selection allows for the survival of members of a species with specific traits

22 Engage When the Galápagos were first formed, there were no plants or animals on the islands. In your comp book, write about some ways that plants and animals from South America could have found their way to these rocky islands. Be prepared to share!

23 Galapagos Islands

24 Natural Selection Card Activity Each group will need 1 standard deck of cards Calculator Procedure Each group member will rotate through the steps of the activity
