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.

drought year?
A) Small B) Large C) Both did well
Investigation: Finch Beaks

Questions:
6) How did a change in the environment affect which beak
size collected more food?
a) The drought left mostly large seeds, which could only be
picked up by the small beak
b) The change in the environment did not affect which beak
could pick up more seeds
c) The drought left mostly small seeds, which could only be
picked up by the small beak
d) The drought left mostly large seeds, which could only be
picked up by the large beak

Questions:
7) Based on the theory of natural selection, how should the
population of medium ground finches change during a
drought year?
a) The population will decrease and those that survive will
have small beak
b) The population will increase and beak variation will also
increase
c) The population will decrease and those that survive will
have large beaks
d) The population will most likely go extinct

12) What is the relationship between the finch
population and seed abundance?
a)When more seeds are abundant, there are more
finches
b)When more seeds are abundant, there are less
finches
c) When less seeds are abundant, there are more
small beaked finches
d)When less seeds are abundant, there are more
finches
Investigation: Finch Beaks
Part 3: Survival on Daphne Major Island
Questions:
13) When they measured the drought survivors, they
found that most were finches with big beaks. Why
do you think bigger-beaked birds survived better
than the smaller-beaked birds?
a)Small-beaked finches moved to a different part of
the island
b)Bigger-beaked finches could eat the tougher seeds,
while the small-beaked finches starved
c) Small-beaked finches could find water as easily as
large-beaked finches.

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
• Elephant vs. Lion
African Desert
• Environmental Change:
– Weather patterns begin to change resulting in
large amounts of rain year round.
Deciduous Forest
• Wasps
Deciduous Forest
• Environmental Change
Drought 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
