Topic(s):Elementary (K-4), Hydrosphere, Oceans
Scenario:None alike and none the same. Some are warm and some cold. Can you find one on a globe? Now take your finger and go around. Follow the ocean between the ground. Keep on going just for fun. Are there many oceans or just one? Stretching far from shore to shore. In bays and gulfs and seas and more. To tell you would take too much time. But would you at least read this rhyme About Earth's ocean water? On a boat or sailing ship. Which oceans would you choose. To be a part of your ocean cruise? Some are cold and some are warm. Some are calm and some have storms. Ocean water blue and green. How many oceans have you seen? Ocean water moves around. Out in the sea and even on dry ground. Water cycle and ocean air. Does your rain water come from there? Near the shore things move about. As tides come in and tides go out. Pulled by a force that you can't see. What do you know about gravity? Up and down ocean waves go. Close to the beach they seem to grow. Like roller coasters they behave. Do you know what causes ocean waves? Ocean water moves in currents, too. Peru, Alaska and Gulf Stream are a few. Some flow down deep and some near the surface. Like water conveyor belts, do they have a purpose? So many ways of moving, oceans' got 'em North and South and top to bottom. Big changes out in the Pacific sea. An El Nino? Now what could that be? Earth's oceans are really grand. But ocean water's not like that on land. Not fresh, it's salty, for fish, just fine. Could you pickle sea cucumbers in ocean brine? Ocean water, there's so much of it. And ocean critters, they just love it. So much water that you can't drink. Are ocean fish thirsty, do you think? So many things live in the sea. And sure, the ocean's a fun place to be. But why should you make such a bother. To learn about Earth's ocean water? Some say there is a change out there. That could change Earth's ocean air. How could that change Earth's ocean water And could we stop it if we were smarter? As you learn about Earth's ocean water, part of Earth's hydrosphere, think about these Essential Questions:
