IS9707 Effect of Salinity on Seawater
The world’s ocean system contain a dynamic thermohaline current system that is responsible for many aspects of our environment. The experiments in this kit have been designed to help visualize the impact solutions of different density have on each other when mixed. Students will measure the salinity of three different water samples representing three major salt water bodies, as well as perform an experiment in which they will observe the flow patterns when different density solutions are mixed. This kit has enough materials for 15 groups. Teacher’s Guide and Student Study Guide Copymasters included.
