🌊 Ocean Currents Lesson Surface Currents • Deep Currents • Gyres • Coriolis • Upwelling

Bring ocean circulation to life with this engaging, NGSS-aligned lesson on ocean currents! Students explore how wind, density, Earth’s rotation, and basin shape work together to drive surface and deep ocean circulation — and how currents impact climate, marine ecosystems, and even plastic pollution.

This lesson blends interactive visuals, guided notes, real-world examples, and critical thinking into a structured, ready-to-use classroom resource.

📘 What’s Included:

✔ PowerPoint / Google Slides presentation
✔ Guided fill-in-the-blank notes
✔ Student worksheet
✔ Complete answer key
✔ Google Quiz (auto-graded option)
