Time to heal the sea

To celebrate British Science Week 2024, we will join the Convex Seascape Survey science team and hear about how marine protected areas (MPAs) are giving the seascape time to ‘heal’.

The team has been working off the Isle of Arran in Scotland and has seen both the devastation caused by human activity and the ability of nature to rebound. We will learn about the different creatures that aid this process and the time it takes for these habitats to recover.

Marine protection is sadly not a magic wand and the lesson will end by looking at some of the wider issues that we can all tackle, including climate change, overfishing, and water quality.

Learning objectives

This live lesson focuses on the themes of:

  • Examine how human activities can have positive and negative impacts on the ocean environment
  • Identify and name some ocean creatures
  • Take responsibility for caring for the ocean

This is a standalone lesson for British Science Week 2024. No specific preparation is needed but teachers may wish to view some of the upper primary (key stage 2) resources from the Convex Seascape Survey.

Supporting student sheets will be available to download from this page after half term.

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

Questions generated by your class can be submitted via the interaction app that will appear on this lesson page once you have booked the lesson.

Lesson steps

1. Introduction (5 minutes)

We welcome classes to the live lesson, meeting Ben and Tara. We will also hear about the amazing work of the Convex Seascape Survey.

2. Impact of human activity (10 minutes)

Ben and Tara take us to the Isle of Arran and we view some of the underwater footage they have gathered of the area. Students will be invited to respond to different views of the seascape, while our scientists explain the timescales involved in wrecking a habitat and its recovery.

3. Seabed habitat heroes (10 mins)

There are some important creatures that are involved in the recovery of the seabed habitat. Ben and Tara will share some of these with classes and their roles, as well as the timescales that each of these work on.

4. Helping habitat heroes (5 mins)

These seabed heroes need our help too. Direct impact on the environment is not the only problem that these creatures face. There are also the wider issues of climate change, pollution, and overfishing.

5. Q&A (15 minutes)

This is a chance for classes to ask Ben and Tara any questions they may have.
