Oceans & Climate Guided Notes + Google Slides | Ocean Currents & Density

Teach ocean currents and their influence on climate with a ready-to-use Google Slides presentation and matching guided notes! This Oceans & Climate resource helps middle school students understand how the world's oceans store, transport, and redistribute thermal energy—and why those processes matter for climate.

Students begin with a real-world climate mystery comparing San Francisco and Sacramento before investigating why land and water heat differently, how oceans moderate coastal climates, and how surface and deep-ocean currents move energy around the planet.

The lesson progresses from concrete ideas such as coastal vs. inland temperatures into density, salinity, thermohaline circulation, upwelling, and global ocean circulation. The included guided notes follow the presentation in order, allowing students to stay actively engaged while reducing the amount of information they need to copy. Students complete fill-in-the-blank notes, make predictions, interpret an ocean-current map, explain cause-and-effect relationships, answer review questions, and return to the essential question at the end of the lesson.
