Salty Science and Buoyancy
Company: NRF/South African Environmental Observation Network (SAEON)
Grade suitability: Grades 10-11
Ocean currents arise in many different ways. For example, wind pushes the water along the surface to form wind-driven currents. Deep ocean currents are caused by differences in water temperature and salinity. In this experiment, the students will hypothesise the cause of ocean currents and then develop a model to explain the role of salinity and density in deep ocean currents. Then we will explore how these ocean currents can regulate climate.
