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.

What does up, must come down. Precipitation is the most commonly seen aspect of the hydrologic cycle. Students will learn how the water cycle works using 3-D paper craft activity. The students will see a demonstration of the concept of precipitation.

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...
