|| **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 is low pressure meaning lousy weather(cold) or its high pressure meaning happy highs(nice day). 2. What four factors affect weather:The air,the sun ,water,the earths movement are the four factors of weather.

Weather vs Climate

3. What is the difference between climate and weather? Climate is along period in time. The weather is just day to day weather!!

Air Pressure
__ [] __ 4. Complete the following chart: warm weather ||. cold ​ weather || clouds and precipitation ||
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || up. || .down ||
 * Temperature of air || high.
 * Wind movement at ground || .air flowing in counter clockwise || flowing out clockwise at the ground. ||
 * Expected weather || air slowly descends || . it rises and sinks often forming

** 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. **

Use the information to complete the chart. The source of this information is American so you may have to determine the equivalent metric unit to record in the chart.

measures in nm || hygrometer measures the amount of humidity measures in F and C
 * ** Instrument Name ** || ** What It Measures ** || ** Unit of Measurement ** ||
 * .Barometer || measures air pressure || ** measures atmospheric pressure in Millibars ** ||
 * Anometer. || measures wind speed ||.
 * measures wind speed in mph ** ||
 * rain guage || measures the amount of rain fall ||

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


 * Use this web site to answer the following questions. **
 * [] **

1. What are clouds? clouds are a major part in weather,clouds make snow,rain.sleet.hail....fall from the sky 2. Explain how clouds form.clouds form when air cools below its saturation point and causes water vaper to condense into tiny water droplets. 3. What are the 3 "families" of clouds and what do their Latin names mean?cirrus means,curl of hair and cumulus means,heap and stratus means,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". [] After completing the chart, you could try a Cloud Quiz at; []

**Forecasting**
|| **Understanding Basic Concepts** -recognize large-scale and local weather systems - predict local weather patterns using data from their own observations of weather and from weather reports - identify patterns in air movement ||

The following questions and organizers will help you keep track of the crucial information you’ll need.
 * Read the details at [] and follow the links.**

Cloud Forecasting

 * **Cloud Type** || **Description** || **Possible Weather** ||
 * cirrus || High level, wispy, hair-like, white tufts, or filaments. Higher than mountains. || no storm ||
 * altocumulus || Middle level layered cloud, rippled elements, generally white, sky showing through || no storm ||
 * nimbostratus || Thicker and darker than stratus, dark grey along base, foggy || possible a storm could happen ||
 * cumulus || Low level, individual cells, puffy, like lumps of cotton, flat bases. || no storm ||
 * cumulonimbus || Low level, very large cauliflower-shaped or anvil-shaped tops. Thunderstorms, lightning, rain and tornadoes. || stormhave a good chance ||

**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. 2. Warm air mass - cool air mass moves in. 3. Brings gentle rains that may last for hours or days.B 4. Strong winds are formed followed by heavy rain, crashing thunder, and flashing lightning.A 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 quicklyA
