  • Science // Ocean Life

    Tides, Waves & Currents

    Know that the ocean has tides (water level rises and falls twice a day, caused mainly by the Moon's gravity), waves (caused by wind), and currents (rivers of…

    The Ocean Floor

    Know that the ocean floor is not flat — it has mountains, valleys, and the deepest trenches on Earth — and that the deepest point is the Mariana Trench, deeper…

    Ages 7 to 9Concept
  • Science // Ocean Life

    Coral Reefs

    Know that coral reefs are built by tiny living animals called coral polyps, that reefs are home to more species than almost any other ocean habitat, and that…

    Ages 7 to 9Concept
  • Science // Ocean Life

    Oceans & Climate

    Understand the connection between the ocean and climate: the ocean absorbs heat and carbon dioxide, drives weather patterns through evaporation, and ocean…
