Rain and hail will be suspended by the updraft inside a thunderstorm until the weight of the hail and water can no longer by supported. Usually, the stronger the updraft in a thunderstorm, the more intense the storm and the larger size of hail that can be produced. Suspending a ping pong ball in th...

The updrafts in thunderstorms can be extremely strong. The stronger the updraft, the more weight of rain and hair that can be supported. This experiment will show thta cotton balls, like clouds, hold a tremendous amount of water. In nature, once the weight of water is more than can be supported by...

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...

Ocean water is salty and, in general, cold. Differences in the water density associated with temperature and salinity are vital in shaping the Great Ocean Conveyor. This lesson plan demonstrates how salinity and temperature affect density of water.

Just as air can have different densities, water can have different densities as well. As the salinity of water increases, the density increases as well. Fresh eggs will float in saltwater, but will sink in freshwater. This will show that as the salinity increases the density also increases.

We all know the oceans are salty but so are other sources of water. The oceans have a salinity (salt content) of 35%. The Dead Sea has an average salinity of 290%, almost nine times saltier than the oceans. But what actually does that mean? Just how salty tasting are these various bodies of water?...

Water moves from the ground to the atmosphere and then returns to the ground, however, the actual path water takes in its cycle is more complicated. There are many stops on water's journey. Students will learn how the water cycle works using 3-D paper craft activity.

At its basic, water moves from the earth's surface to the atmosphere and then returns to the surface. However, the actual path water may take in its cycle is far more complicated. The students will discover more of these cycles by acting as water molecules and travel through parts of the overall...

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...

Water is the most abundant and important substance on Earth. It is essential to life and is a major component of all living things. There are approximately 336,000,000,000,000,000,000 gallons of water on Earth, existing in three states: solid, liquid, and gas. The sources for this water storage are...
