The Tuna/Dolphin Controversy – Part 2 Students examine case histories of human use and management of dolphin populations. Unit 2- Dolphin Adaptations 1. Hear Sighted Students analyze data as they role-play dolphin features and echolocation. 2. Dolphin Adaptations: Echolocation Slinky wave puzzles are used to determine the distance between a student and an object. Unit 3- Dolphin Food Chains & Webs 1. Food Web Students make a physical model of food webs, food chains and pyramids to show the interrelationships of organisms, nutrients and energy in a marine ecosystem. 2. String for Your Supper Student teams create a mobile representing an ocean food web. Below, you’ll find helpful resources for use with the above activities.
