All about Oceans

All about Oceans introduces students to the world of these giant bodies of water. Students will discover how waves form and what tides are. They will also discuss depth and how the ocean floor varies greatly.

There are several suggestions in the “Options for Lesson” section that you can use in your class, either as additional or alternative activities. One such option is to assign one part of the ocean to each student and have them research it and create a poster to present to the class or display in the classroom. Another option is to obtain supplies for students to create a model of the ocean floor that can demonstrate waves, tides, and so on. You could also let the students use construction paper for the activity.

What our All about Oceans lesson plan includes

Lesson Objectives and Overview: All about Oceans teaches students some of the traits of the largest bodies of water. Students will be able to identify and explain such traits as tides, waves, depth, and so on.

This lesson contains five content pages. The first page explains how water covers 70% of the earth’s surface, and almost all of it is salt water. Students will discover how oceans help divide the land into continents. They will learn some the characteristics of oceans, such as how they became salty and what the ocean floor comprises.

Students will discover the concept of currents. They will learn that currents keep water moving around the globe in constant flow. The water from tropical areas moves north or south to warm the cold water in the polar regions and vice versa. This keeps the oceans balanced.


The activity worksheet has five empty boxes across two pages. Students will draw a picture that depicts five different ocean parts. The five parts are waves, tides, depth, floor, and salt. They can use information from the content pages to help them remember the properties of these different parts. They will need to use arrows and symbols or labels to help viewers understand what ocean part the picture depicts. Students can work with partners or groups instead of by themselves if you prefer.


For the practice worksheet, students will first read 10 definitions. Using the words in the word bank, they will match the terms to the correct definition. Then, they will answer 12 questions using the facts they learned during the lesson.


The homework assignment requires students to review 15 numbers that relate to the lesson. Students will explain how each number is significant as it applies to oceans. Then they will read five sentences and fill in the blanks with the right ocean part.
