Curated OER
Estuarine Currents
Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.
Curated OER
Hot, Cold, Fresh and Salty
Students observe the effects of layering water and what is more or less saline than normal. In this geoscience lesson students create saline solutions, layer them and observe how the water becomes different temperatures in different layers.
Curated OER
Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.
