In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

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.

Making liquids of different densities to perfectly lay on top of each other can be a frustrating exercise. The Exploratorium created this activity as a fool proof way of making a density column.

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

In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

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 chemistry activity (page 1 of the PDF), learners will observe a physical change.

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

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.

In this activity, learners compare different types of salt crystals under a magnifying glass.
