Thursday: February 23rd

Class Agenda1.) Complete Article Presentation (sharing question

answering information from yesterday.)2.) Watch David Attenborough segment on

“Origins of Life”(approximately 25mins)

While watching movie complete worksheet which corresponds with the movie. (This worksheet I will collect at the end of class for assessment purposes.)

3.) When movie commences you will exchange your paper with your neighbor and mark each others responses in PEN. I will utilize my PowerPoint to have a discussion on the movie and go over the correct answers!

4.) Turn in all papers at the end of class!

Ms. Fisher

Objective for today:Through media you will get a final look on how life began for animals 600 million years ago.

You will look at odd animal fossil remains, and complete a worksheet which corresponds

with the movie. This worksheet will be collected

and assessed.

DAVID ATTENBOROUGH

Would you like some sweets while viewing our short movie?!

Evolution(Primitive Sea Creatures Similar to Sea

Creatures of Today…)

Movie Discussion:1.) Five hundred forty two million

years ago what kind of animals existed on the ocean floor?

Cambrian animals

2.) There were many kinds of odd animal fossil remains found from the Cambrian Period. What kind of animal in particular rummaged the ocean floor, looked like a

worm, and had 5 eyes? Opabinia

Why did these animals need 5 eyes?As the predators became bigger & stronger

(evolved,) the prey needed 5 eyes to help it spot trouble.

(The prey evolved as the predators evolved!)

3.) Who was the first predator on Earth? Hint: The mouth was originally thought to be a fossil jellyfish, the grasping arms were originally thought to be large shrimp, and the soft body was originally thought to be part of a sponge.

Anomalocaris

If you traveled to the Great Barrier Reef, what kind of animal would you most likely see there? One whom is very similar to the

ancient Anomalocaris and many say directly evolved from this species.

Mantis Shrimp

5.)What animals developed protective shells?

Arthropods

Name 4 Different Arthropods from today: Shrimp Lobster Crabs Centipedes TrilobiteName an Ancient Arthropod: Trilobites

Assessment: Objective Through media you will get a final look on how life began

for animals 600 million years ago. You will look at odd animal fossil remains, and complete a worksheet which

corresponds with the movie. This worksheet will be collected and assessed.

What kind of animals existed on the ocean floor 542 million years ago?

Cambrian animals

Why did these animals look so odd? Example, have such features as 5 eyes?

As the predators evolved, the prey too evolved! Predators got stronger, so the prey adapted to survive.

Good-bye my friends! I had a blast! I hope everyone feels like they have a good grasp on the concept of evolution! Until next time we meet! I

will miss you all…
