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.

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

Learners carefully look at four known household crystals.

In this activity on page 6 of the PDF, learners dissolve Epsom salt in water and discover that the resulting solution can be used to create a work of art.
