What is Weather?
[]

1. Define weather. The condition of the atmosphere at a certain time or place. 2. What four factors affect weather? Air, wind, the Earth's movement and water all affect the weather.

Weather vs Climate
__ [] __

3. What is the difference between climate and weather? Climate is what you predict but, weather is the exact outcome.

Air Pressure
__ [] __ 4. Complete the following chart:
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || Down || Up ||
 * Temperature of air || Up || Down ||
 * Wind movement at ground || Clockwise || Counter- Clockwise ||
 * Expected weather || . Good || . Bad ||

** Measuring the 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. **

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

<span style="font-family: 'Times New Roman',Times,serif;">1. What are clouds? Clouds are a visible mist of water and ice particles in the sky. 2. Explain how clouds form. Clouds form when the air cool past saturation point and causes vapors in the air to condence and turn into water droplets. 3. What are the 3 "families" of clouds and what do their Latin names mean? Cirrus:Strand of hair, Cumulus:Heap and Stratus:Layer 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".

**Warm and Cold Fronts **
|| **Understanding Basic Concepts** - explain the difference between warm and cold fronts and the factors that influence both of these systems - identify types of weather associated with each front || []

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. B 2. Warm air mass - cool air mass moves in. 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 becomes humid. B 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
