In this activity, learners explore sublimation by conducting experiments with dry ice.

“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.

In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this weather-related activity, learners make a portable cloud in a bottle.

In this activity, learners discover that sand is the major ingredient in glass.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
