Description

Transform the osmosis and water potential concept into an engaging, hands-on classroom experience with this station-based activity! Students rotate through scenario cards featuring real marine organisms—fish, plankton, crabs, anemones, sargassum, and more—analyzing how changes in salinity affect survival. Using the Claim–Evidence–Reasoning (CER) framework, students explain each scenario while practicing the scientific vocabulary and reasoning skills needed for success on the Cambridge AICE Marine Science A level exam.

Why Teachers Love This Resource:

✔ Student-Centered Learning – Keeps students moving and engaged with station rotations.

✔ Exam-Focused Practice – Directly reinforces osmosis, diffusion, active transport, and water potential.

✔ Flexible Implementation – Use as a full-period lesson, review activity, or test prep station.

✔ Supports CER Writing – Encourages students to explain concepts scientifically, strengthening higher-order thinking.

What’s Included:

• Matching game (hypertonic, hypotonic, isotonic, cell shrink/swell) for a quick warm-up
• 10 scenario station cards with marine organism examples
• Student answer sheet with blank CER sections for each station
• Teacher instructions for both the matching game and stations activity
• Answer key with completed CER examples

Make osmosis and transport processes memorable, interactive, and exam-ready with this stations activity designed specifically for AICE Marine Science classrooms!
