LEQ: How is geologic evolution related to
biologic evolution?
1. What is extinction?
2. A rock is dated between 300 and 500 years old. Is
this an example of relative or absolute dating?
3. Explain your answer from #2.
4. What is an index fossil?
5. What is the difference between weathering and
erosion?

2. CONTEXT CLUES:
1. My ancestors were American Indians. Even
though I do not speak the native language, I
am so proud of my ancestry!
2. My dog’s offspring all look exactly like my
dog! Even though they are still puppies, they
have the same spots!
3. Over time, my opinion has evolved. At first, I
thought the Mavericks were going to win, but
not I think the Lakers are going to win.

19. Think-Pair-Share
What adaptations does
this animal have that
helps it survive in its
environment?

20. Think-Pair-Share
What adaptations do these animals have that help
them survive in their environment?

21. Think-Pair-Share
What adaptations do these animals have that help
them survive in their environment?

22. Geologic Evolution: the ways that
the earth changes over time
Biologic Evolution: the ways that
species change over time
Adaptation: a Natural Selection:
physical trait
inherited from a
common ancestor

24. COMMON
ANCESTOR

25. FIND THE COMMON ANCESTOR!!!

the earth changes over time
Biologic Evolution: the ways that

27. HOT QUESTION #2
• Fossils have shown that ancient frogs had gills
similar to modern day fish. This fact can be
best explained by which of the following:
a. radiometric dating
b. extinction
c. evolution
d. climate change

28. You should be:
Natural Selection • Thinking silently.
Example
• Which rabbit has a better chance of
surviving in the North Pole? Why?

29. All the brown rabbits die
Only one white rabbit dies

30. White rabbits have babies

31. Now we have ALL white rabbits!

32. PEPPERED MOTHS
pre-industrialization
Which moth would be more likely to
survive? WHY???

33. PEPPERED MOTHS
post-industrialization
Which moth would be more
likely to survive? WHY???

34. Geologic Evolution: the ways that
the earth changes over time
Biologic Evolution: the ways that
species change over time
Adaptation: a Natural Selection:
physical trait
inherited from a
common ancestor

35. Natural Selection: certain traits that
help a species survive become more
common over time (also called “Survival
of the Fittest”)

36. What adaptations would increase
survival in this environment?

37. What adaptations would increase
survival in this environment?

38. What adaptations would increase
survival in this environment?

39. Pick a card, any card!
• 1: Your environment temperature increases & green
fur is too dark. Your species becomes extinct.
• 2: A new predator has invaded your environment.
This predator eats yellow species. If you have a
yellow card without an X on it, sit down. If you have
an X, you adapted strong leg muscles and outran the
predator.
• 3: There was a flood that wiped out green Xs’ food
sources. You couldn’t adapt fast enough! You go
extinct!
• Everybody that’s left survived. You adapted to the
changing environment!

40. THINK-PAIR-SHARE
1. What were the different adaptations?
2. How did your environment change?
3. In the end, which adaptations were
“naturally selected”? (Which species
was the fittest for the changing
environment?)
4. Do you think that all of the species had a
common ancestor? Why or why not?

41. Brain Pop—Evolution

42. SUMMARIZER ACTIVITY!
Forkasaurus
Spoonbill Platypus
Knife Monster

43. SUMMARIZER
1. What adaptation allowed one animal to eat more
than the other?
2. Which animal would be favored (chosen) by the
process of natural selection?
3. How would you predict these animals to evolve
over time? (Would some become extinct?)
4. What change in the environment would make an
animal with a different adaptation to survive?
(Ex: what would have to happen in the environment
in order for the knife monster to survive?)
5. Do you think these animals had a common
ancestor? Why or why not?
