In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
