LEARNING TARGET #4
I can explain what adaptations are, give examples, and
explain how it relates to diversity of life.
Adaptations
The enormous diversity of species in
the five kingdoms is in part a result of
the wide range of adaptations to the
many types of environments on
earth. Within all the variations of the
species, which were a result of
mutations in their DNA, the best
adapted survive. Through this
evolution, a new separate species
would develop that kept becoming
more different from the old one. In
the end, that is why all life started as
bacteria and now we have millions of
different organisms on earth.
 The wide range of adaptations to the many types of
environments is the reason we have an enormous
diversity (differences) of species on earth.
Which kingdoms have adaptations?
 *** ALL living things have adaptations – animals,
plants, fungi, protista, and monera
ADAPTATION – something that helps an
organism survive in its environment.
2 types:
1. STRUCTURAL (physical) – a trait; something you can
see on the organism
* caused by mutation in DNA
2. BEHAVIORAL – way the organism acts; something it
does
ALL organisms need to be adapted to their environment in
order to survive.
REMEMBER
Organisms CANNOT CHOOSE an adaptation, it must
happen through a mutation or learned behavior.
VIDEO 1: List all the changes and
adaptations of elephants over time
EX of structural adapt.
1. camouflage
2. thick fur / shedding
3. spines/ tusks
4. spray smells
5. body part size/shape
6. mimicry
tons more!
 Mimicry allows one
animal to look, sound, or
act like another animal to
fool predators into
thinking it is poisonous or
dangerous.
Teeth in rows pop up
SNAKE
CHAMELEON
All birds have similar
characteristics.
But many water birds
have features that
are different from
those birds live on
land.
Webbed
feet for
swimming
Long legs are good for wading
These wings act as flippers
Adaptation to
temperatures
Polar bears are kept warm by
their body fat.
Deer have a
warm layer
of fur.
Layers of fat keep the
seals body warm, and small
ears stop heat loss.
OTHER COOL ADAPTATIONS
Polar bears have hollow hair, so they can trap more heat.
WARM UP #5
11/18
DOUBLE CREDIT DAY – have 7 minutes to do
1. What is the definition of an adaptation?
2. What were the two types we were talking about?
3. Do all living things have adaptations? (ex, bacteria and
fungi?)
4. REVIEW: What kingdom is eukaryote and unicellular?
5. REVIEW: Which of the 7 levels is most diverse?

WHAT WERE
SOME
STRUCTURAL/
PHYSICAL
ADAPTATIONS
WE TALKED
ABOUT?
camouflage
Some crickets and toads can freeze solid, and come back to life after they thaw
out.
For many reptiles, the sex of their offspring is determined by temperature, and
not sex chromosomes.
Albatross bird can sleep flying
Birds bones are hollow so they are lighter – they also do not have a bladder.
Birds do not have a bladder
A human adaptation – skin
color
EX of behavioral adapt.
1. Moving in herds
2. Migration
3. hibernation
4. Playing dead
5. Sitting on rocks
to keep warm
6. Digging holes for protection
ANNOUNCEMENT
about TUES.
I am going to be in school
here conducting a
learning walk.
You will have an
assignment for you.
1. It is a 20 point grade to be
on the “good behavior list”.
2. The assignment 3.14 is DUE
IN CLASS ONLY – no late
or makeup
3. The assignment is DOUBLE
CREDIT - TWO GRADES
4. Expect a good class report +5 or -5 on competition
REST OF THE HOUR – 3.13
 You are going to look at
PLANT ADAPTATIONS
by reading an article,
highlighting the
adaptations, then
writing them into
“leaves”.
TURN THIS IN WHEN
DONE
 YOU WILL BE
GETTING YOUR
GRADES WHILE YOU
WORK
 IF YOU FIND
ANYTHING THAT YOU
HAVE TO TURN IN ,
GET IT IN!!!!
EXIT TICKET
I can describe what adaptations are, give 3 examples of
the 2 types, and explain how it relates to diversity of
life.
1. Write the answer to the above target to show me that
you understand.
Human adaptations
 Sweating to cool off
 Opposable thumb
 Language to communicate
 Skin colors
 Body shapes and size
 Layers of fat
 Clothes / shelter
 Agriculture
 Use of oxygen by our cells
 Malaria/ sickle cell
PLANTS HAVE ADAPTATIONS TOO
Can you think of any?
VIDEO – ditto to fill in
PLANT ADAPTATIONS
EX:
 Spines
 Waxy leaves
 Deep roots
 Wide leaves
 Covered seeds
 Thick bark
 Drop leaves
Tons more!
Even plants have
adapted to their
habitats.
The cactus has fleshy stems
that store water.
Dandelions seeds are
easily dispersed.
The water provides support for this lily
as it has less developed roots to hold it
in place.
How did plants first begin? Where did they live? How
did they evolve?
READING ON CELL TO SEED

What is the definition of adaptation?
What are the two main types?
Give 3 examples of each type.
Do you think plants have adaptations? If so, can you
name any?

 For example, imagine a bird species. One day a bird is born
with a beak that is longer than the beak of other birds in
the species. The longer beak helps the bird catch more
food. Because the bird can catch more food, it is healthier
than the other birds, lives longer and breeds more. The
bird passes the gene for a longer beak on to its offspring.
They also live longer and have more offspring and the gene
continues to be inherited generation after generation.
 Eventually the longer beak can be found in all of the
species. This doesn't happen overnight. It takes thousands
of years for a mutation to be found in an entire species.
