Revive the Ocean

Teacher Tips

Hook

• Read the SOS prompt aloud and let it land before asking for answers: the ocean produces at least half the oxygen we breathe, most of it made by phytoplankton, tiny drifting plant-like organisms most learners have never heard of. It also regulates the climate and supports millions of species, all while under real pressure. Give the discussion a full minute before taking feedback.
• If you want a more visual version, you could have learners write their one-sentence SOS message on a post-it and stick it to the board as they finish discussing. It’s optional, but it builds a shared, visible starting point before you move into the science.
• There’s no single correct SOS message, so it helps to take a range of answers before revealing the Big Question. The aim is to spark curiosity and a bit of emotional connection, not to land on one right response.

ITZA Pathways

• The two pathways split visible from invisible harm. Pathway 1 (Revive the Ocean) covers what you can see: plastic, overfishing, fertiliser runoff and dead zones, coral bleaching. Pathway 2 (A Sea Change) covers what you can’t: carbon emissions changing the ocean’s temperature and chemistry. Both matter equally to the Big Question, so it helps to keep an eye on the clock and make sure the class reaches Pathway 2.
• Circulate with “What are some of the challenges facing ocean ecosystems today?” It’s a good check that learners are absorbing specifics, not just watching content pass by.
• If a learner already knows a real example, such as a local beach clean, the 5p plastic bag charge or a David Attenborough documentary they’ve seen, you could let them bring it in. Personal connections help a lot in this session.

Classroom Activity

• Frame it as a UN mission: groups are tasked with identifying which factors harm the ocean and which help it, then deciding where limited funding should go.
• Part 1 (4 mins): groups sort the factors on the slide into just two groups, helps the ocean and harms the ocean. There’s deliberately no “unsure” option. It pushes groups to discuss and commit rather than parking anything they’re not sure about. Take feedback before revealing the correct categorisation.
• Part 2 (4 mins): groups choose only three solutions to invest in and must explain what problem each one solves and why it matters more than the options they didn’t pick. With only three slots, groups can’t hedge with near-identical choices. That tension is the point, so you could push back gently if a group’s three picks all address the same problem.
• For groups who finish early, you could push them further with a follow-up question rather than moving straight to feedback: “Which of your three tackles the cause rather than just the symptom?” It separates root-cause thinking from surface fixes.

Plenary

• Part 2’s reflective question is the Big Question itself: “Why is the ocean in so much trouble, and what would it take to bring it back?” By now learners should be able to answer it using evidence from both pathways, not just repeating a fact from earlier.
• The lock-in is from Sir David Attenborough. It’s worth reading it slowly and letting it land before moving into the journal.
• Close by holding both truths at once, not picking one: the damage is real, and recovery is genuinely possible. You may see learners tipping into either complete hopelessness or uncritical “it’ll heal itself” optimism. Both miss the point the session is making, which is that the outcome depends on what we do next.
