A page in layers, from sunlit water to the deep (see below).

One ocean, five basins

There is really one global ocean. It covers 71 percent of Earth and is divided into five named basins: the Arctic, Atlantic, Indian, Pacific and Southern (NOAA). Write the five names on the board and let each child choose the ocean their page shows.

The biggest animal that has ever lived

Blue whales are the largest animals ever to live on our planet. In the Antarctic they can reach about 110 feet long and weigh more than 330,000 pounds, and they feed almost entirely on krill, tiny shrimp-like animals (NOAA Fisheries). Measure 110 feet across a playground or a gym, then color the whale page.

Most of the deep ocean is unseen

More than 90 percent of the ocean is deep ocean, below 200 meters (656 feet), and explorers have seen less than 0.001 percent of the deep seafloor. As of April 2026, 28.7 percent of the global seafloor had been mapped with modern high-resolution sonar (NOAA Ocean Exploration).

That leaves room for imagination: ask children to invent a deep-sea animal nobody has seen yet and draw it on the back of their page.
