Covering some 70 percent of Earth's surface, clouds play a key role in our planet's well-being. But how do they form, why are there so many types, and what clues can they give us about the weather and climate to come? Try your hand at classifying clouds and investigating the role they play in severe...

We're heading out of this world to compare atmospheric compositions of the other planets in the solar system, as well as our own. Practically every other planet in our solar system can be considered to have an atmosphere, apart from perhaps the extremely thin, transient atmosphere of Mercury, with...

Learn how to identify cloud types by using this flow chart from the International Cloud Atlas. Clouds are divided into 10 fundamental types known as genera, depending on their general form. The genera are then further subdivided based on a cloud's particular shape, structure and transparency; the...

Clouds are divided into four basic forms (Cirro-form, Strato-form, Cumulo-form and Nimbo-form) at three basic levels (low, middle, and high) in the atmosphere. Many locations may experience all of these different types of clouds daily. The students will become better observers of the sky by...

In a clean-air chamber (all solid particles are filtered out) a cloud will not form even with a relative humidity greater than 200%. While clouds are made up of droplets that are essentially distilled water, each droplet is not 100% pure. At the cloud droplet's core is a tiny water attracting...

Collision and coalescence is the process by which cloud droplets grow large enough to fall as rain in clouds. You will suspend two ping pong balls in the stream of air supplied by a hair dryer. The balls will bump into each other, creating a clicking sound signifying the collision.

Onjects float if they weigh less than the weight o the water they displace. Conversely, onjects will sink if they weigh more than the weight of the water they displace. Students will observe how the added sigar in a can of soda affecs its ability to float in water by the change of density.

There are three states of matter: gas, liquid, and solid. Water in our atmosphere exists in these three states constantly. As the temperature of water vapor (a gas) decreases, it will reach the point at which it turns into a liquid (called the dew point or the point at which dew forms). This change...

There are two methods water moves from the ground to the atmosphere as part of the hydrologic cycle. Transpiration is basically evaporation of water from plant leaves. Studies have revealed that transpiration accounts for about 10% of the moisture in the atmosphere, with oceans, seas, and other...
