** 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.** The WEATHER is the condition of the atmosphere (or changes in the atmosphere) at a particular time and place. ** 2. What four factors affect weather
 * ** the air **
 * ** the sun **
 * ** water **
 * ** the earth's movement **

Weather vs Climate
__ [] __ 3. What is the difference between climate and weather? **Climate ** is what you expect; **Weather** is what you get.
 * Climate** is about long-term records, trends and averages;
 * Weather** is the day to day experience.

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

u ||
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || down || up
 * Temperature of air || cold || warm ||
 * Wind movement at ground || clockwiclockwise || Counterclockwise ||
 * Expected weather || good weather || .bbadad weather ||

** 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 ||

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


 * ** Instrument Name ** || ** What It Measures ** || ** Unit of Measurement ** ||
 * ​ Barometer || ** 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. ** || ** measures atmospheric pressure in Millibars ** ||
 * Thermometer || ** Thermometer: measures the temperature ** || ​ **Celsius or degrees Fahrenheit** ||
 * ** Rain gauge ** || ** Not only does a rain gauge measure rainfall, but also all other forms of precipitation. ** || ​ ** rainfall in mm ** ||
 * ** Campbell Stokes Recorder ** || ​ ** measures sunshine ** || ** number of hours of sunshine in the day. ** ||
 * ** Anemometer: ** || ** measures wind speed ** || ** mph ** ||
 * ** Wind Vane ** || ​ ** measures wind direction ** || ** pointing towards North, East, South or West ** ||
 * ​** Hygrometer: ** || ** measures the temperature and amount of humidity ** || ** Fahrenheit and degrees Celsius. ** ||

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

1. What are clouds? 2. Explain how clouds form. 3. What are the 3 "families" of clouds and what do their Latin names mean? 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: Incomplete 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. 4. Strong winds are formed followed by heavy rain, crashing thunder, and flashing lightning. 5. When the front passes, the temperature warms up and it becomes humid. 6. When the front passes, the weather turns cooler. 7. Farmer Brown prefers this type of front. 8. Usually happens and is over with quickly.
