Have you ever wondered how animals are able to survive in the
wild?
Animals have certain adaptations that help
them to survive.

Who is more fit to their environment?
• Polar bears are not naturally found where there are brick walls and dirt.
The brown bear blends in with the flora found in the Canadian wilderness.
That’s better!

Think about the way you dress in the winter.
You don’t wear your shorts and bathing suit when it’s snowing outside!
You wear warm clothes, and maybe even a hat and mittens to protect
yourself from the weather.

And what if you are having a snowball fight?
You probably run away from the person throwing at you,
and maybe even try to sneak up on that person and
throw some snowballs!

The way you dress in the winter, as well as the way that you run and hide from
someone throwing snow at you are kinds of …
Adaptations

We can separate adaptations into two categories:
Physical and Behavioral

Physical adaptations
are body structures that allow an animal to find and consume food, defend itself,
and to reproduce its species.Physical
adaptations help an animal survive in its environment.

stick. I look just like a
stick you’d find on the
ground.

Physical adaptation
Camouflage (use of color in a surrounding)
The chameleon can change its color to match its surroundings. Can you do that?

Mimicry (looking or sounding like another living
organism)
The Viceroy butterfly uses mimicry to look like the Monarch butterfly. Can you tell them apart?

Not poisonous
Physical adaptation
I’m the Monarch!
I’m the Viceroy!

Body coverings & parts (claws, beaks, feet, armor plates, skulls, teeth)
Physical adaptations
The elephant’s trunk is a physical adaptation that helps it to clean itself, eat, drink, and to pick
things up.

Now let’s learn about
Behavioral Adaptations…
Behavioral Adaptations allow organisms to respond
to life needs.
![Page 14: 5 th Grade Life Science toad Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive.](https://reader035.fdocuments.net/reader035/viewer/2022062516/56649e695503460f94b6560d/html5/thumbnails/14.jpg)
Each organism has unique methods of adapting to its environment by means of
different actions or behaviors.
Behavioral Adaptations are organisms’ actions.
Remember that physical adaptations are body
structures.
![Page 15: 5 th Grade Life Science toad Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive.](https://reader035.fdocuments.net/reader035/viewer/2022062516/56649e695503460f94b6560d/html5/thumbnails/15.jpg)
We can divide Behavioral Adaptations into two groups:
Instinctive Learned
These behaviors happen naturally & don’t have to
be learned.
These behaviors must be taught.

Instinctive behaviors happen
naturally & don’t need to
be learned
=
Finding shelter
Methods of gathering & storing food
Defending oneself
Raising young
Hibernating
Migrating

Learned behaviors
Obtained by interacting with the environment and cannot be
passed on to the next generation
except by teaching.

Review . . .In this lesson, we have learned about
animal adaptations.
There are 2 ways to describe adaptations:
Physical and Behavioral
![Page 19: 5 th Grade Life Science toad Have you ever wondered how animals are able to survive in the wild? Animals have certain adaptations that help them to survive.](https://reader035.fdocuments.net/reader035/viewer/2022062516/56649e695503460f94b6560d/html5/thumbnails/19.jpg)
Physical adaptations are body structures.
Some examples of physical adaptations are:
Camouflage
Mimicry
Body coverings & parts
Chemical defenses

Behavioral Adaptations are animals’ actions.
Behavioral Adaptations can beInstinctive or Learned.

How do adaptations help animals survive in their environment?
• Remember, an adaptation is a body part or behavior that helps an animal survive in a particular environment.
• Adaptation can help an animal breathe, catch food, protect itself, get water, or reproduce.
• All organisms are adapted to live in certain habitats.• Organisms that cannot adapt will become ill or perish.• Organisms that are adapted to their environment will
reproduce and make offspring with the same adaptations.

Adaptation Questions on TAKS
• TAKS likes adaptation questions.
• For these, think about the environment the organism is in and what its MOST important needs are!
• Examples• Desert species need water, cooling system• Tundra species need to keep warm• Saltwater species need to remove extra salt, breath
underwater
