Free - Caring for the ocean

For this final lesson of Submarine Live 2022, we look at different areas of the ocean around the Maldives to see how human activity is affecting their health.

We will take time to compare and contrast these two areas and ask classes to share how they feel. Our Maldivian expert will talk classes through some of the ways in which you can see whether the ocean is healthy or not.

The final section of the lesson will focus on the factors that affect ocean health and what we can all do to help.


This lesson looks at the impact of human activity on the environment and how local and global changes are needed to conserve the ocean for the future.

There are two student sheets that can be downloaded for this lesson. You may want to print these out for students.

If you have never joined a live lesson before, visit the support centre, where you can find a range of technical and educational information.

Once booked, questions generated by your class can be submitted in advance via the Live Lessons tab in your profile.

Lesson steps

1. Introduction (5 minutes)

We welcome classes to the expedition and location, meeting our guest speaker. This is also a chance to go over the learning for the lesson and cover digital housekeeping.

2. Exploring the ocean (10 minutes)

We will visit two areas of the ocean in the Maldives to see the difference between healthy and unhealthy areas. Students will be asked to record and share their impressions and feelings, before being guided on how to spot some of the signs of health in the sea.

3. What affects ocean health? (5 minutes)

Students will learn about what affects the health of the ocean with a focus on those factors that are common to many areas of our blue world, including carbon emissions, water quality, pollution, and overfishing.

4. Taking action for the ocean (10 minutes)

Working in small groups, students will consider what actions they would like to take to conserve the ocean. Our Maldivian expert will also share some of the work that they are doing. Classes are encouraged to share their ocean pledges so that we can showcase the positive work being done.

5. Q&A (15 minutes)

This is a chance for children to ask any questions they have about the changes happening in the ocean, and what we can all do. Are plastics found in the Maldives? What change would we want governments to make?
