Students study how humans impact dolphins and sea turtles with the Ocean Life student activity.
- Identify animals, more specifically mammals, and their characteristics
- Identify what sounds the animals make
- Spell different animals names
- Research animals and put that information to use
- Use songs, books, pictures, and the Internet to accomplish most of these objectives

Comparing Marine Mammals
Objective: Students will be able to identify a marine mammal and compare and contrast it to all mammals.
Introduction: Does anyone know what a marine mammal is?
Read: Sea Otter Rescue by Roland Smith, the sections relevant to marine mammal description and encyclopedia definition.
Step 1: Review the characteristics of mammals: they have hair or fur; they have two or four legs; their babies are born live (discuss difference between "egg laying" and "live bearing.") Review the characteristics of marine mammals (percentage of life lived in water, warming adaptations, water adaptations).
Step 2: Students will be able to identify which animal is a marine mammal when shown two animal pictures. "Why is or is it not a marine mammal?"
Read a characteristic or fact from a marine mammal (otter, whale). Haves students take turns identifying which marine mammal the fact describes.
Step 3: When a student guesses correctly, ask him or her to add another fact about that animal.
Conclusion: All students should be able to explain why an animal is a marine mammal.
Sea Otter Predators
Objective: Students will be able to understand the predators sea otters face in the wild.
Introduction: Read Lootas Little Wave Eater: An Orphaned Sea Otter's Story by Clare Hodgson Meeker.
Step 1: Play a game called Whale and Otter. Go outside to the playground area. Mark out a rectangular playing area. On one end, place paper sea urchins (sea otter food) that you or your students have made. In the center area, place about four hula hoops, which represent the kelp forest.
Step 2: Break your students into groups: orca whales and sea otters. Try to have one whale per four otters. Have the orca whales start at one end, swimming around the "ocean" (field). The object is for the sea otters to cross the ocean three times and get a sea urchin each time without being "eaten" (tagged) by an orca whale. Otters can "hide" in the kept forests and are safe from the whale, but can only stay there for one minute.
Step 3: The mother sea otters must get five sea urchins. Have one handicapped sea otter who has survived an attack by a killer whale. He has to hop on one foot. Play several rounds varying the ratio of whales to otters.
Conclusion: Discuss and graph the results of each round.
Sea Otter Habitat
Objective: Students will be able to make a model of a kelp forest.
Introduction: Sea otters live in kelp forests. Have the students make a model of a kelp forest.
Step 1: Using a piece of brown paper about 20 feet long, cut a "kelp stripe" about four inches wide.
Step 2: Next, have students make the kelp leaves out of green bulletin board paper. The length of the leaves should be about one foot. Make sure they make a "bladder" at the base of each leaf. Staple the leaves along the sides of the stripe. Hang the stripe from the ceiling of the classroom. To make a canopy, staple some of the stripe across the ceiling.
Step 3: Make a kelp holdfast out of baggies filled with salt or sand. Make rocks out of foam blocks, spray painted gray. Place the holdfasts on top of the rocks.
Step 4: Students can make large fish and sea mammals to suspend from the ceiling. They can make starfish and sea urchins out of clay and put them on the ground.
Conclusion: Students will love reading in their kelp forest now that they can describe a Californian sea otter habitat.
After engaging in the activities, students should be able to answer the following questions:
- What makes sea otters special?
- Where do sea otters live?
- What is a marine mammal, and which animals do we classify as marine mammals?
- What do sea otters eat?
- How do we obtain information using the computer to inform others on our sea otter?
Use the Ocean Life Writing Rubric as a way to assess your students' writing skills. This rubric can also serve as a model for a modified version that might include your state's writing standards.
This project aids students in meeting national standards in several curriculum areas.
Reading Language Arts
