[26-May-2022] In part one of this two-part lesson students work in pairs to explore the effects of salinity on ocean stratication using a simple plastic shoebox-sized container in which they create a mini-ocean environment. Students will apply what they learn in the lab setting along with information gained in several online articles to a basic understanding of the Global Conveyor Belt and its effect on global climate.
This hands-on activity is suitable for learners in the middle grades and above, and takes about 1 week to complete in a formal education setting. Authors have provided extensive notes on objectives, lesson preparation, procedures, standards covered, extensions and resources, assessment worksheet and lab discussion questions, and credits.
