Description:

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle. Learners will also investigate how a liquid's density affects objects that are put into it. This experiment connects with estuary environments (habitats where fresh water and ocean water mix) and also contains a brief discussion of one of the saltiest seas on earth, the Dead Sea in the Middle East.
