Kemtec Science: Physical & Chemical Resources of the Living Ocean
Kemtec Science
SKU: KEM-9-124
This kit is designed to examine salt, not only as the most obvious property of seawater, but also as one of its most valuable chemical resources. Students learn about the varying salt concentrations of seawater and its amazingly uniform composition. They also learn how salt can be removed from seawater. Experiments include: determining salinity by evaporation, determining salinity using a hydrometer, desalination by freezing, and desalination using a solar still. Allow five class periods.
