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.

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.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.

Don't scream for ice cream -- make it with milk, sugar, flavoring and some 'salt-water' ice. Discover the chemistry of ice cream by creating your own.

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.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

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.

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.

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

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

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.
