This Ocean Explorer interactive, hands-on lesson plan (PDF) leads students on an exploration of deepwater adaptations by addressing the focus question: What types of adaptations enable deep-sea fishes to survive and collect food in the darkness of the deep ocean? In the activity, students search for Skittles in a dark room while wearing goggles covered in blue cellophane to simulate deepwater feeding. This lesson plan includes a reproducible student handout and links to reference resources.
