• Tips & Modifications

    Tip

    Laminate the individual sheets of the MapMaker Kit map so you can re-use it for several years.

    Modification

    You can adapt the activity for different MapMaker Kit sizes as needed for different settings.

    1. Establish student background on the ocean.

    Show students a physical world map, and have volunteers point to an ocean. Ask: Has anyone been to an ocean? Can you point to it on the map? As a group, find the Atlantic, Pacific, Indian, and Arctic Oceans.


    2. Students explore ocean boundaries on the World Physical MapMaker Kit.

    Distribute the tabletop version of the World Physical MapMaker Kit to students in small groups, or use the MegaMap with the whole class. Ask students to draw the boundaries of each ocean on the map with markers. Have students work in groups to try to draw these lines. They may struggle, because there are no true lines separating oceans. In effect, there is really only one ocean. Discuss this finding with students. Ask: How can we say there are "four oceans" and also there is "one ocean"? Isn't that a contradiction? Why do you think maps typically name four oceans?"


    3. Discuss issues of ocean stewardship.

    Discuss implications of Earth’s one ocean and how this creates challenges for ocean stewardship. Water, animals, plants, pollution, and people travel throughout the world on this constantly moving body of water. Ask: What do you think this means for marine life, and for the use and care of the ocean? Talk about environmental and human implications, such as overfishing and water pollution, and potential impacts on ecosystems and people's food sources. Brainstorm ways the ocean's resources can be protected and conserved.

    Extending the Learning

    • Have students look at five to ten other bodies of water such as the Gulf of Mexico, the Caribbean Sea, the Mediterranean Sea, the Arabian Sea, and the Phillippine Sea. Have students try to draw boundaries for them. Ask: What challenges do you think countries that need to share these bodies of water face? What challenges might there be in protecting all of these interconnected bodies of water?

    Skills Summary

    This activity targets the following skills:


    National Standards, Principles, and Practices

    National Geography Standards

    • Standard 3:  How to analyze the spatial organization of people, places, and environments on Earth's surface
    • Standard 4:  The physical and human characteristics of places

    Ocean Literacy Essential Principles and Fundamental Concepts

    • Principle 1a:  The ocean is the dominant physical feature on our planet Earth—covering approximately 70% of the planet’s surface. There is one ocean with many ocean basins, such as the North Pacific, South Pacific, North Atlantic, South Atlantic, Indian and Arctic.
    • Principle 1h:  Although the ocean is large, it is finite and resources are limited.

  • Background Information

    All of the oceans and seas on Earth are interconnected making one world ocean. Many boundaries that seemingly separate these bodies into separate entities are manmade for navigational or political reasons.
