KEY POINT 1 The Earth’s oceans contain

both living and nonliving resources

Oceans Case Study: Finding Nemo

• “Field Trip-11:47”, “The Abyss 33:00-35:11” • As you watch these clips from the movie,

answer the questions on your guided note sheet.

• This will be GRADED!

THINK, PAIR, SHARE (2 minutes)

1. Is life in the ocean diverse… meaning are there different kinds of life?

2. What kinds of ocean life do you see?

3. Why does Nemo look different from the fish his father ran into with Dory?

Let’s focus on this last question.

You’re right…

• The fish all looked different because they lived in different parts of the ocean

Is the Ocean the SAME throughout?

• NO!

• How does the ocean change from one area to another?

Key Point # 2Ocean life depends on 3 factors…

1. Sunlight

2. Temperature

3. Depth

Ocean life

o Sunlighto Plants require sunlight to liveoAnimals rely on plants for oxygen,

protection, and a food source

Ocean Life

o TemperatureoDecreases with depthoCold salt water is the most dense

oAquatic life is adapted to a particular temperature

Ocean Life

o DepthoThe deeper you go, the less sunlight and

less heat there isoThere is also less food at deep depthsoAnimals at these depths must either eat

each other, hunt for falling plankton from above, or dead carcasses that sink to the bottom

Let’s see what animals in the depth of the ocean look like…

1. What adaptation does the Octopus Dumbo have that allows it to live in the deep ocean?

2. What adaptation does the Vampire Squid have that allows it to live in the deep ocean?

CHALLENGE

How do sunlight, temperature and depth affect the diversity of ocean life?

Animals in the ocean must adapt to various ocean habitats…these habitats are dependent upon how much light they can receive.

HOT Q #1

• I am going on a submarine ride. As I move from the surface of the ocean to the deep zone, how will the marine life change? 1. Draw a picture of an animal I’d see at the

surface of my submarine dive2. Draw a picture of an animal I’d see deep in

the ocean of my submarine dive

Upwelling Demo

• Watch what happens to the substance.

• What happened??

Upwelling

oMovement of nutrient rich cold water from the depth of the ocean to shallow areas near the shore. oBrings nutrients and minerals that are

important to marine life oBecause of this, many animals live

where upwelling occurs

Upwelling

Turn and talk

• Explain to your partner what upwelling is in 30 seconds

HOT Q #2

oWhy would a fisherman fish in an area with upwelling?oCome up with a valid reason

HOLD THE PHONE….Did you know…

o There is ANOTHER ending to Finding Nemo?

oWatch “Back to the Reef”

Alternate Ending

After Nemo and his dad are reunited at the end of the movie, they do not return to the reef

Instead, they move to an Estuary….with Dory of course.

They meet all kinds of new friends, friends that look completely different.

Nemo’s New Friends at the Estuary

Why do these animals look Different from Nemo’s friendsBack at the reef?

Answer

• This is a different habitat than the ocean environment that Nemo and his friends live in.

Estuarieso Places where fresh water from rivers meets salt water

from the ocean o Rich in a wide variety of living thingso They are protected by barrier islands which give a lot

of dissolved oxygen, nutrients, and minerals – all necessary for life to exist in water environment

HOT Q #3

• Why do estuaries support such a wide variety of different life forms?

Key Point #3

• Upwelling and estuaries connect marine and land life

Conclusion

1. What kinds of resources live in the ocean?2. What factors affect ocean life?3. What is upwelling?4. What is an estuary?
