- Student Printable 3: Dolphin Map (PDF)
- Explain to students that there are many animals of all shapes and sizes roaming the world’s vast oceans. There are fish, sea turtles, snails, urchins, coral, sponge and thousands more. But one of the most fascinating of all are the marine mammals, which include whales, dolphins and porpoises. Cetaceans are mammals best adapted to aquatic life. There are many species of Cetaceans—also known as whales (which includes porpoises and dolphins).
- Pass out student printable 1 (PDF) and ask students to read additional background information on mammals, cetaceans, whales, and dolphins. Grade K-2 teachers: use the student printable as a way to share this information with your students.
- Once students have finished reading the article, ask students to answer a series of True/False questions about cetaceans and dolphins. Grade K-2 teachers: gather students in a circle and read the true/false questions out loud. Encourage class discussion.
- Explain to students that dolphins are part of a much larger marine world. A healthy marine environment supports a large food web, which includes many plants and animals. Pass out student printable 2 (PDF) and ask students to identify and order the different plants and animals of the marine food chain. Grade K-2 teachers: Explain that a food chain describes the eating relationships between species within an ecosystem or a particular living place. Write the names of the animals and plants on the board. Ask students to guess the proper order of the food chain.
