** The Elements of Weather **
|| **Understanding Basic Concepts** - explain the difference between weather and climate and the factors that influence both of these systems - identify patterns in air movement - identify the effects of air pressure ||

What is Weather?
[]

1. Define weather. ** Weather occurs in the part of the earth's atmosphere called the troposphere. This is the layer which is closest to the earth's surface, or the actual sky that we can see. ** 2. What four factors affect weather __ [] __ 3. What is the difference between climate and weather? There is a variety of ways to explain the difference. Here are a few that may shed some light
 * the air
 * the sun
 * water
 * the earths movment
 * Weather vs Climate

Air Pressure
__ [] __ 4. Complete the following chart:

down || .down up || warm ||. cold || slow || .fsdff fast || nice || lousy ||
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) ||.
 * Temperature of air ||.
 * Wind movement at ground ||.
 * Expected weather ||.

|| **Developing Skills of Inquiry, Design and Communication** - design, construct, and test a variety of weather instruments - use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations ||

 * The following web site describes some of the instruments meteorologists use to collect data about the weather. **

Compas || measures wind speed || measures sunshine || measures wind speed || measures the tempature and amount of humidity ||
 * measures the temperature in degrees Celsius or degrees Fahrenheit **
 * ** Instrument Name ** || ** What It Measures ** ||  ||
 * Barometer ** ||
 * measures atmospheric pressure in Millibars. A barometer can also be used by pilots as an altimeter, because as a pilot flies upward, the pointer gives the altitude above sea level. ** ||

 * Rain gauge ** || ** .Rain gauge: measures the amount of rainfall in mm. Not only does a rain gauge measure rainfall, but also all other forms of precipitation. ** || measures th eamount of rainfall in mm ||
 * Campbell Stokes Recorder: ** ||
 * Campbell Stokes Recorder: measures sunshine. This type of recorder is made up of a glass ball which concentrates sunshine on to a thick piece of card. The sunshine then burns a mark on the card which shows the number of hours of sunshine in the day.: measures sunshine.

 * Anemometer: measures wind speed in mph. The most common type looks like a toy windmill. Three cups are fixed to a central shaft and the stronger the wind blows the faster they spin around. The wind speed is shown on a dial, just like a car's speedometer. ** ||

 * Hygrometer: ** ||
 * Hygrometer: measures the temperature and amount of humidity in degrees Fahrenheit and degrees Celsius. A hygrometer actually uses human hair to tell how much humidity is in the air. It contains a sheaf of blond human hairs treated to remove the oils. As the relative humidity increases, the hairs increase in length and operate the recording mechanism. ** ||

** Clouds **
|| **Understanding Basic Concepts** - explain the formation of clouds and the effects of different cloud formations on weather and climate ||

1. What are clouds?** Clouds are a major part of our weather. ** 2. Explain how clouds form.** Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets. ** 3. What are the 3 "families" of clouds and what do their Latin names mean?** There are three families of clouds: cirrus, cumulus, and stratus. These are the latin names given to clouds in 1804. Cirrus means 'curl of hair', cumulus means 'heap', and stratus means 'layer'. Clouds can also be classified by their altitude, whether they are located low, middle or high in the sky. ** 4. Follow the links to learn about each type of cloud and then complete the table on the next page. To help you identify clouds, download, print and construct the following "Cloud Key".

Cloud Forecasting

 * **Cloud Type** || **Description** || **Possible Weather** ||
 * cirrus || ** low altitude clouds ** || ** Cirrus" in latin means curl and these clouds are named because they resemble wisps of curly hair ** ||
 * altocumulus || ** If these clouds thicken, then precipitation is likely ** || ** Rain and snow often accompany the development ** ||
 * nimbostratus || ** These clouds are low altitude clouds that are not more than 5,000 feet above the Earth ** || ** Nimbostratus clouds color the sky a solid gray ** ||
 * cumulus ||
 * Cumulus clouds can cause rain, although rain does not always follow cumulus clouds. ** || there like cotton balls ||

Write the capital letter A or B at the end each sentence. A = Cold Front B = Warm Front 1 . Cool air mass - warm air mass moves in. 2. =A 3. Brings gentle rains that may last for hours or days=B 4. Strong winds are formed followed by heavy rain, crashing = A thunder, and flashing lightning. 5. When the front passes, the temperature warms up and it = A becomes humid. 6. When the front passes, the weather turns cooler. =A 7. Farmer Brown prefers this type of front. =B 8. Usually happens and is over with quickly. =A
