2 200 Meters Down Have you people heard about the plankton? Just tiny algae and it s floating, right What about the nekton like jellyfish? They swim around and survive Moving through the water column While the benthos crawl by Dive in you re heading for the open ocean Try as you may - you cannot see the sunlight oh oh 200 meters down Searching for some warmth from a hydro hydrothermal situation Where bubbles come from cracks in ocean floors oh See the crabs and the worms Your bioluminescence Gives ya light in deeper zones On the rocky shores Are pounding waves Where salinity and the temperatures change Mix in river water to get estuaries Those mangrove trees Protect us please Better than marshes of salt From the bay of the Chesapeake Zones go through the surface zone Yea zones through the transition zone Now you re almost home La la la la We started intertidal and went neritic Here is shallow shallow water - lots of plants in it Most ocean life comes here to eat On the coral reef In the sunlight and warmth Or the - Kelp forest Cold water by the rocky floors

4 Name: Ocean Zones Have you people heard about the plankton? Just tiny algae and it s floating, right What are plankton? 200 Meters Down How do plankton move? Plant plankton are called. Animal plankton are called. What about the nekton like jellyfish? Are Jellyfish plankton or nekton? Explain. What are nekton? They swim around and survive How do nekton move? Moving through the water column Where do nekton live? List 3 examples of nekton organisms. While the benthos crawl by What are benthos organisms? How do benthos organisms move? List 3 examples of benthos organisms. Dive in you re heading for the open ocean The 3 zones of the ocean are

5 Try as you may - you cannot see the sunlight oh oh 200 meters down How far below the water s surface does sunlight penetrate? The area where sunlight penetrates is called the zone. Searching for some warmth from a hydro hydrothermal situation The prefix hydro- means. The root word thermal means. Where bubbles come from cracks in ocean floors oh What is a hydrothermal vent? Where do hydrothermal vents form? Is there any sunlight at hydrothermal vents? See the crabs and the worms What kind of organisms can survive at hydrothermal vents? 4. How do vent organisms survive without sunlight? Your bioluminescence What is bioluminescence? How do organisms produce light? Most bioluminescent light is. Gives ya light in deeper zones List 2 examples of bioluminescent organisms.

6 On the rocky shores One type of habitat found in the intertidal zone is the Are pounding waves Where salinity and the temperatures change Organisms in the intertidal zone must tolerate 4 extreme conditions. 4. The water remaining after the tide goes out is called the pool. What extreme conditions must tide pool organisms be able to withstand? Mix in river water to get estuaries What is an estuary? The term used to describe water that is partly salty and partly fresh is Those mangrove trees An example of an estuary is a. Define a mangrove forest. Mangrove forests are located mainly off the western coast of. Protect us please How do mangrove forests offer protection to the coastline? Better than marshes of salt Another example of an estuary is a. Define a salt marsh. From the bay at the Chesapeake A large protected salt marsh on the East coast is the Bay. Zones go through the surface zone Yea zones through the transition zone

7 Now you re almost home List 3 zones of the open ocean. The only zone capable of supporting photosynthesis is the. We started intertidal and went neritic Here is shallow shallow water - lots of plants in it Where is the neritic zone? Most ocean life comes here to eat Why does most ocean life come here to eat? On the coral reef True / False - A coral reef is made of dead organisms. List the process of developing a coral reef 4. In sunlight and warmth Why do so many organisms live in coral reefs? Where is the world s largest coral reef system? Or the - Kelp forest What is a kelp forest? Cold water by the rocky floors Kelp forests prefer a water temperature. Why are kelp forests a good place for organisms to live? What do coral reefs and kelp forests have in common?

9 Name: KEY Have you people heard about the plankton? Just tiny algae and it s floating, right 200 meters down What are plankton? Organisms that float in the water, and are moved around by currents How do plankton move? The drift with the currents Plant plankton are called phytoplankton. Animal plankton are called Zooplankton. What about the nekton like jellyfish? Are Jellyfish plankton or nekton? Explain Jellyfish are actually considered to be plankton do you think they should be considered nekton? Why or why not? What are nekton? Fish that are able to swim up and down in the water column. They swim around and survive How do nekton move? They swim! Moving through the water column Where do nekton live? Throughout the water column List 3 examples of nekton organisms. Whale Shark Jellyfish While the benthos crawl by What are benthos organisms? Organisms that live on the ocean floor How do benthos organisms move? They Crawl! List 3 examples of benthos organisms. Crab Starfish Lobster Dive in you re heading for the open ocean The 3 zones of the ocean are Surface

10 Transition Deep Try as you may - you cannot see the sunlight oh oh 200 meters down How far below the water s surface does sunlight penetrate? 200 Meters The area where sunlight penetrates is called the Surface zone. Searching for some warmth from a hydro hydrothermal situation The prefix hydro- means Water. The root word thermal means Heat/Warm. Where bubbles come from cracks in ocean floors oh What is a hydrothermal vent? Cracks in the ocean floor Crack in the ocean floor heated by magma. Look like bubbling Where do hydrothermal vents form? Near cracks in the ocean floor Is there any sunlight at hydrothermal vents? No! Too deep. See the crabs and the worms What kind of organisms can survive at hydrothermal vents? shrimp tube worms clams and mussels 4. crabs How do vent organisms survive without sunlight? vent. Other organisms eat those bacteria to get their energy. Bacteria living at the vent that eat sulfides emitted form the cause your bioluminescence What is bioluminescence? A cold light produced by living organisms. How do organisms produce light? Light is produced by a chemical reaction that occurs in special cells called photocytes. Most bioluminescent light is. Gives ya light in deeper zones List 2 examples of bioluminescent organisms. angler fish plankton

11 On the rocky shores One type of habitat found in the intertidal zone is the Rocky Shore Are pounding waves Where salinity and the temperatures change Organisms in the intertidal zone must tolerate 4 extreme conditions. Extreme temperature changes Water, then no water Waves pounding 4. Salinity changes The water remaining after the tide goes out is called the Tide pool. What extreme conditions must tide pool organisms be able to withstand? Changes in salinity because water evaporates making salinity increase, changes in temperature, force of waves when the tide comes in again Mix in river water to get estuaries What is an estuary? A location where saltwater is mixed with freshwater The term used to describe water that is partly salty and partly fresh is Brackish Those mangrove trees An example of an estuary is a Mangrove Forest. Define a mangrove forest. Brackish water with short, gnarled trees and swamp dwelling organisms. Mangrove forests are located mainly off the western coast of Florida. Protect us please How do mangrove forests offer protection to the coastline? Protects the coastline against erosion Better than the marshes of salt Another example of an estuary is a Salt Marsh. Define a salt marsh. Smelly, muddy brackish waters with lots of sediments, tall grasses and nutrient rich waters. From the bay at the Chesapeake A large protected salt marsh on the East coast is the Chesapeake Bay. Zones go through the surface zone Yea zones through the transition zone

12 List 3 zones of the open ocean. surface transition deep The only zone capable of supporting photosynthesis is the Surface Zone. Now you re almost home La la la la We started intertidal and went neritic Here is shallow shallow water - lots of plants in it Where is the neritic zone? Shallow waters over the continental shelf Most ocean life comes here to eat Why does most ocean life come here to eat? Lots of sunlight, stable conditions, and lots of food On the coral reef True / False A coral reef is made of dead organisms. List the process of developing a coral reef Tiny coral animals (called polyps) produce a hard structure surrounding their soft body. When the coral dies, the empty structure remains New coral animals attach and grow on top 4. After many years, a reef is built! In sunlight and warmth Why do so many organisms live in coral reefs? Lots of food. Protection from predators. Where is the world s largest coral reef system? Australia, Great Barrier Reef Or the - Kelp forest What is a kelp forest? Area of large, heavy seaweed that grow as dense forests on rocks Cold water by the rocky floors Kelp forests prefer a Cool water temperature. Why are kelp forests a good place for organisms to live? Good place to hide, lots of oxygen in the water due to photosynthesis, good place to raise young What do coral reefs and kelp forests have in common? Both provide protection for diversity of life

13 Music Video Extension Activity Hand out or project the lyrics and read them out loud and discuss their meaning Play the song for the students, multiple times, encouraging them to sing along Use the student lyric guide in place of, or to supplement class notes 4. Allow students class time, in small groups, to act out a portion of the song 5. Film the student groups singing/acting out the song
