In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight. To simulate this process, learners work in pairs (one blindfolded and one using a water gun), shoot at targets, listen to the sound of the water hitting the target, and attempt to guess the target's shape and material. Learners also analyze how distance affects echolocation and how tuna nets impact dolphins' ability to echolocate.
