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.

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.

Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

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.

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 will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

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.

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

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

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.
