Introduction: Prior to beginning the lesson: (1) Cut out and laminate Vocabulary Cards for display in the classroom; (2) Photocopy Ocean Zone Image onto transparency paper for the overhead projector; (3) Photocopy Ocean Zones onto transparency paper for the overhead projector; (4) Photocopy Ocean Zones (1 per student).
Group Size: Whole Class
Students will be able to:
·Identify the four zones of the ocean.
·Name characteristics of each ocean zone.
Materials:Vocabulary Cards (see attachment), Ocean Zones (see attachment)
1.Tell students: Now that we have learned all about the water and the water in the oceans, let’s talk about ocean zones. Display vocabularycard “ocean zones”. Tell students: Ocean Zones are the layers of the ocean.
2.Display Ocean Zone Image on the overhead projector. Ask students: What do you notice about the different ocean zones? Give students time to share observations. Tell students: Today we are going to learn about ocean zones.
3.Ask students: What is the first zone in the ocean? Call a student to read Sunlight Zone. Tell students: Ninety percent of all plants and animals that live in the ocean live in the Sunlight Zone. Why do you think that is? Guide students to answer it has the most sunlight. Continue to tell students: It is the only zone fully lit by the sun.
4.Distribute a copy of OceanZone to each student and display a copy on the overhead projector. Use the Teacher’s Answer Key to help guide students to fill it out.
5.Display Ocean Zone Image again. Ask students: What is the next zone? Call a student to read Twilight Zone. Tell students: The Twilight Zone gets very little sunlight. No plants grow here. Some of the sea creatures that live in the Twilight Zone have special organs that grow in the dark.
6.Display OceanZone again. Use the Teacher’s Answer Key to help guide students to fill it out.
7.Display Ocean Zone Image. Ask students: What is the next zone? Call a student to read Dark Zone. Tell students: The Dark Zone gets no sunlight at all. It is pitch-black. No plants grow here, and there are very few animals. The animals that do live here have to be good hunters because food is so scarce.
