This hands-on laboratory activity introduces students to ocean stratification by exploring how salinity and temperature directly influence water density. Using common classroom materials, students create vivid, color-coded layers in a graduated cylinder to visually model real-world marine environments. The comprehensive resource includes clear background reading, step-by-step procedures, observation diagrams, and critical thinking analysis questions to solidify student understanding of global oc

This engaging, print-and-go graphing activity challenges students to analyze and plot temperature and salinity depth profiles using real-world contextual data from Camano Island, WA. By constructing a dual-line graph and answering targeted comprehension questions, students will visually explore how these variables determine water density and drive ocean stratification. It’s a low-prep, highly effective resource for earth science or oceanography teachers looking to reinforce data-literacy and g
