Objective
Given a description of a dangerous animal, the student will be able to create an adaptation that would protect a human from that animal.
Background
An adaptation is a modification of an organism that makes it more suited to live in its environment. Adaptations can be a body part or behavior that help an animal survive. These adaptations include protective spines, sharp teeth, poisonous flesh, and stinging cells. Some adaptations may be dangerous to humans.
Action
1 . Divide the class equally into small groups. Choose one student from each group to be the "moderator." Give each moderator a card that names one dangerous sea animal. Through role-playing, each moderator describes the animal to their group, giving all the information she or he can about the animal's dangerous characteristics.
2. The others in the group represent humans faced with the challenge of surviving in the sea. In turn, each group member names an adaptation that would help them survive if they encountered this animal.
3. Within each group, students discuss the survival adaptations each of them named. Ask the group moderator to point out how or if she or he could overcome each adaptation. Each group chooses one adaptation that would help them the most.
4. Each moderator describes the chosen adaptation to the rest of the class.
5. Compile a complete "Oceanator" from all the groups' ideas. Choose a student to illustrate the "Oceanator" on the blackboard. Discuss how well this "Oceanator" would survive all dangers of the sea.
Deeper Depths
Discuss human interactions with ocean ecosystems (transportation, recreation, harvesting food, etc.). Human activities can accelerate environmental changes. By changing the environment, we can completely destroy a habitat for which an animal is adapted. If the animal lacks the adaptations necessary to live there, it could become extinct. Are any dangerous animals threatened or endangered species? If so, why? In the same groups, or as a class, create adaptations that may help protect these animals from extinction.ters or popular myth and movie sea monsters. Materials
cards or slips of paper with the names of dangerous sea animals written on them. Find suggestions at Dangerous Denizens.
