It’s World Oceans Day today!
Did you know that oceans occupy 71 percent of the world’s surface? There are five main bodies of seawater that are designated as oceans, namely, the Pacific Ocean, Atlantic Ocean, Southern Ocean, Arctic Ocean and our very own Indian Ocean.
Check out the Marine WATERs Lesson Plan: Oceans Divided to learn more about out oceans, seas, gulfs, bays and bights! The characteristics of a body of water determine whether it is a bay, bight or sea.
In Activities 1 and 2 of Oceans Divided students will map the bodies of water, covering that 71 percent of our planet. As an extension to this activity, why not ask students to research how and why the these bodies of water are so named.
Similarly to the land masses around the world, the ocean floor is not one vast, flat expanse. The highest peak on land, Mount Everest, stretches 8,850 metres above sea level. Contrast, the deepest part of the ocean, the Mariana Trench, is 10,912 metres below sea level. You can use the Marine WATERs Lesson Plan: Getting Deeper to learn about the bathymetry of the world’s oceans and add this information to the map created in Activities 1 and 2 of Oceans Divided.
