Ocean Pollution & Harm
Identify ways humans harm the ocean — plastic pollution, overfishing, oil spills, and ocean acidification from carbon dioxide — and understand that most ocean pollution comes from land-based activities, not just ships

Teaching Table
Set out your lesson
Practise the bounded task in Ocean Pollution & Harm; see exact limits before inferring broader coverage.
Can connect a cause to harm; no beach cleanup, litter handling or personal seafood advice.
Exact directed source edges retained; earlier authorship is not learner attainment.
These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate
Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.
Use the supplied screen cards; copying the exact task to paper is optional, not required.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
Qualitative mechanisms; no percentage attribution, local-source identification or measured environmental effects.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Check understanding
- Name at least three ways humans harm the ocean
- Explain that most ocean pollution originates on land, not from ships
- Describe how plastic pollution or overfishing specifically harms marine animals
“If your child saw plastic washed up on a beach, could they explain where it came from, how it harms sea life, and name other ways humans damage the ocean like overfishing and pollution from factories?”
