Analyzing maps with the current weather conditions is an essential part of the entire forecast process. Basically, if we do not know what is currently occurring, it is near impossible to predict what will happen in the future. In this lesson plan, the students will determine the location of cold and...

Meteorologists often refer to ridges and troughs in the upper atmosphere when explaining the reason for the weather one experiences. Yet all one sees are lines on a weather map. However, these weather systems are high and low places in the atmosphere as this lesson will demonstrate.

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.

We feel the wind everyday. The air is almost always in motion. One day it may be from the north and the next day from the south. There are many sources for wind: mechanical sources such as fans and, in nature, falling rain as it drags air along. But what is the origin of wind on the earth? Using a...

Sometimes a claim is made that Christopher Columbus sailed west to prove the world was round and not flat, but that wasn't the case at all. Even in ancient times sailors knew that the Earth was round and ancient scientists not only suspected it was a sphere, but even estimated its size. Measuring...

The Earth is in constant motion. Each day the earth makes one complete rotation. Each year, the earth makes one orbit of the sun. The first motion is obvious. The second one, however, is muh harder to notice except over a much longer period and can be made visible only by some time and some...

We observe the different angles between the sun, earth, and moon by the phases of the moon we see each month. Students, acting as the earth, will see differences in light and dark sides of their hand-held moon.

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.

The constant pushing of molecules into each other if the reason we feel wind. As one molecule bumps into another, it transfers energy into the next molecule. This constant pushing on the oceans surface also transfers energy to the water. This energy transfer is responsible for the motion of the...

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.

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?...

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...
