1 Ocean Habitats Theresa Barba

2 Oceans Today’s Objective:
I can identify the Ocean as a habitat and will be able to describe it’s characteristics. Around 70% of the Earth is covered by oceans. The five oceans are the Pacific, Atlantic, Indian, Southern, and Arctic.

3 Have You Ever Been to the Ocean?
Stand Up, Hand Up, Pair Up to find a partner. In one minute, take turns sharing your experiences. If you have never been to the ocean, share what you think it would be like. After one minute, some of you will share some ideas your partner shared with you.

4 Oceans We will begin our lesson by watching an interactive video about Ocean habitats. As you watch, jot down one fact, idea, thought, or question. We will discuss these after we watch.

5 What Are the Three Ocean Zones?
If you have been to the beach, in which zone of the ocean have you probably been?

6 Sunlit (Euphotic) Ocean Zone
Sunlight hits this zone the most, so there are specific plants and animals that can survive here. Plants: Seaweed, phytoplankton, flowering plants Animals: Sharks, rays, jellyfish, most ocean fish, seals, coral, sea turtles

7 Twilight (Disphotic) Ocean Zone
The middle layer of the world's oceans receives only faint, filtered sunlight during the daytime. This is because the seawater absorbs some of the sunlight.  Plants: There is not enough light for photosynthesis to take place, so no plants live at this level. Animals: Many of the animals in this zone have large eyes (to help them see in the dark waters) and are small, dark and thin (to help camouflage them). They also have large teeth and jaws. Many animals in this zone are bioluminescent – they can make their own light! Some examples of Twilight Zone animals are algae, crabs and other crustaceans, dragonfish, fangtooth, hatchet fish, lantern fish, some octopuses, mid-water jellyfish (Cnidarians), plankton, sea dragons, some shrimp, some squid, viperfish and many worms. lanternfish Cnidarians dragonfish

8 Midnight (Aphotic) Ocean Zone
The deepest layer of the world's oceans gets no sunlight at all. The temperature is almost freezing and gets colder the deeper it goes. Plants: There is no light from the sun, so photosynthesis does not take place. Therefore, there are no plants. Animals: Some examples are algae, anglerfish, cookie-cutter shark, crabs, vampire squid, pelican eel, and viperfish. Like the twilight zone, many are bioluminescent! Take a look at some of the strange, beautiful creatures in this zone.

9 Ocean Habitats Exploring the Coral Reef
To end our Ocean Habitats lesson, we will take a virtual trip into the Coral Reefs! Exploring the Coral Reef What is your favorite fact about the Ocean? Why?
