They're most numerous in the Arctic, the Antarctic, and areas of cold-water upwelling. Killer whales are found in both the open ocean and coastal waters. Ask students to bring a large, round piece of fruit such as a honeydew melon, grapefruit, orange, or apple from home.
Students draw and label the world's oceans on their piece of fruit.
If there is room, students label seas, major straits, and bays. Have students pair up. Write the questions at right on the board, and have each pair work together to write down the travel directions. When everyone has finished, ask students to share their answers with the class. At the end of the activity, invite students to eat their fruit globe.
