Try this experiment with your class. Condensation in relation to temperature and water vapor in the air is shown through a simple experiment using cold glasses. Show this clip to your class or repeat this experiment and hold a scientific...

Matter can change from one phase to another through heating or freezing. This video fully and clearly describes the changes that occur when water freezes or boils. Solid narration, clear description, and good examples make this a good...

Somewhere inside of every raindrop there is a tiny impurity. Learn here about without these microscopic pieces of dirt there would be no rain because water vapor cannot condense into droplets on its own. [2:37]

Did you know clouds are just big clumps of water droplets? This video explores how clouds are made and the types of clouds. [3:36]

A young student poses the question "How does water vapor make a cloud" to a meteorologist. Watch his explanation in this video. [1:51]

Learn to make a very impressive cloud form in a plastic bottle! By pumping air into an empty plastic bottle and quickly releasing the pressure, we can cool off the air and force the water to condense into a thick cloud. It's a very...

A video poem describing the path water takes as it travels through water cycle as it evaporates, condenses and turns into precipitation. [1:50]

A video showing an experiment to find out the reason why water collects on the outside of a cold glass. The experiment concludes that the water must come from the water vapor in the air. [1:44]
