Ocean Pollution & Harm

CONCEPTUAL

Science›Ocean Life|Ages 9—11|ID: mt_J6uccv2Bo4

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

Mastery Evidence

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

Assessment Prompt

“If [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?”
