This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.

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.

In this quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

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.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.
