33. DO NOW Date: Jan. 24 th 2014 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.

34. 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.

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

36. 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.

37. 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.

38. The Arctic Polar bears 1 Polar Bears 2

39. 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.

40. African Desert Elephant vs. Lion

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

42. Deciduous Forest Wasps

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

44. Antarctic Fur Seals and Penguins

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

46. 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
