How Do Dolphins Sense Their Environment? (Level: Middle School)

Includes two activities that demonstrate how dolphins gather information about their environment. In the first activity, students communicate information to one another using vocalizations and their bodies, but not words. In the second activity, students attempt to locate a dropped object using only their hearing. Students fill in data tables and answer discussion questions as they complete each of the two activities. Extensions are included for the elementary and high school levels.
