In this Xpeditions lesson, students consider the significance of the hammerhead shark's “hammer.” They watch two videos and compare the way hammerhead sharks and white sharks swim. Students click through an interactive shark diagram to learn about sharks' senses and hypothesize about how hammerheads' head shape might enable them to use their senses differently from other types of shark. They conclude by writing paragraphs answering the question: “What good is the ‘hammer’ for a hammerhead shark?” From this page, teachers can access all the materials needed to complete this lesson.
