Introduction: If you compared the color of a glass of tap water with a glass of water scooped from the middle of the Pacific Ocean, you probably could not tell the difference. But if you go to the beach, the ocean may look blue, gray, or dark green. The ocean water doesn't actually change color. The ocean reflects the color of the sky. 99-1/2 percent of the ocean is made of 9 chemicals. These 9 chemicals form many compounds .
Activities and Procedures:
1.) Using the periodic table, the students will match the chemicals to its symbol.
sodium chloride S

2.) Students will write a short paragraph explaining why the ocean might look blue on one day and gray or dark green the next day.
3.) Using the encyclopedia, students will find out how the Red, Yellow, and Black Seas got their names, and write a report on each in their own words.
4.) Using a blank world map, students will color and label the Red, Yellow, and Black Seas.
