5. Using Echolocation to Map the Atlantic Ocean Floor 15 Points
If the Atlantic Ocean did not have any water, what would the surface look like? There would be mountains, canyons, and plains. It would be as varied as the land now is. How can you find out what it looks like? Before the 1920's the only way to measure the depth of the ocean was to use a weighted line with mesasurement marks. They knew where deep water and shallow water was. In the late 1920's, scientist developed an instrument called the Echo Sounder. It records the time for a sound wave signal to travel from a ship to the ocean floor and back. Sound travels through sea water at a speed of 1500 meters per second. By using echolocation it was then easy to compute the depth of the ocean. The ocean depth is equal to the echo time x speed of sound (1500 meters per second). By taking soundings at different points, calculating the ocean depth and then plotting the depths on a graph a cross-section of the Atlantic Ocean floor is created.
A. Draw a cross-section of underwater topography.

9. How does the ocean get its salt? 2 Points
10. Grape Races 10
One of the major concerns about climate change is the melting of the polar ice caps and the added freshwater that would be added to oceans. Many scientists say the global ocean currents will change which will alter the climate. The density of the water affects the current. The amount of salt will affect the density. Let's see how.
250ml graduated cylinder
1. Fill the 250ml graduated cylinder with water.
2. Drop a grape and time how long it takes to hit the bottom.
3. Fill the graduated cylinder again and add 2.5 grams (10 ppt.) of salt.
4. Stir the salt until it is dissolved.
5. Drop the grape and record the time.
6. Continue adding 2.5 grams of salt and record the time it takes the grape to hit the bottom.
7. Graph you results looking for a pattern.
How might changing the salinity affect the living organisms there?
There are few diadromous fish ( fish that can tolerate both freshwater and saltwater. Name one.
11. Coral Reefs 5 Points
Tons of coral make up the coral reefs. After the coral dies, it leaves its skeletons, made of calcium carbonate, behind.
Describe the three different kinds of reefs:

21. Ocean Diorama 10
Create your own ocean scene in a box. Find pictures of ocean animals like sharks, crabs, snails,and reef fish. Add seaweed and coral. Paste, color, cut, hang them in a decorated box, and enjoy the ocean.
Pictures of ocean animals and plants
Pipe cleaners for sea weed and coral
1. Decorate the inside of the box to look like it's underwater. Draw the water, the ocean floor, rocks, coral, seaweed, fish, an octopus, bubbles, scuba divers, a submarine, etc. Glitter makes a wonderful addition - just sprinkle some on a little glue.
2. Print out pictures of ocean animals to use.
3. Using crayons or markers, decorate the animals and plants. Also, draw and decorate your own seaweed, corals, and favorite fish. Green construction paper cut in squiggly strips makes nice seaweed.
4. Cut out the animals and plants.
5. Hang the fish and whales in the box using tape and thread. Tape your seaweed and coral to the bottom of the box. Green and brown pipe cleaners also make nice plants.
