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.
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.
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
DO NOWDate:JAN 22ND & 23RD
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.
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.
Adaptive Advantages
• Complete the handout on your own first.
• Once completed, compare and discuss your answers with a partner.
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.
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.
The Arctic
• Polar bears 1• Polar Bears 2
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.
African Desert
• Environmental Change:– Weather patterns begin to change resulting in
large amounts of rain year round.
Deciduous Forest
• Environmental ChangeDrought causes the trees to produce far less acorns, and the ones that are produced are half the size.
Antarctic
• Fur Seals and Penguins
Antarctic
• Environmental Change:There is no change. Discuss what adaptations could occur if the environment stays the same.
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

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
EngageWhen 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!

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