** 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. The weather is shaped by 4 main factors **

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.


 * Climate** is the sum or synthesis of all the weather recorded over a long period of time. It tells us the average or most common conditions, or extremes, or counts of events, or frequencies. **Weather** is a description of conditions over a short period of time - a "snap shot" of the atmosphere at a particular time.

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

warm || cold || strong || . weak || ​
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || down || up ||
 * Temperature of air || .warm
 * Wind movement at ground || .
 * Expected weather || not expected || expected ||

** 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. **

millibars ||
 * ** Instrument Name ** || ** What It Measures ** || ** Unit of Measurement ** ||
 * .Barometer || air pressure ||
 * .Anemometer || collect wind speed || .mph ||
 * Psychrometer || measure humidity || ||
 * Thermometer || air temp. || F and C ||

** 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 visible mist of billions of water and ice particles floating in the sky. ** 2. Explain how clouds form.** The water droplets then form a cloud. The cooling is usually caused by by rising air, the way that the air rises effects the type of cloud that is produced. ** 3. What are the 3 "families" of clouds and what do their Latin names mean?** The names of the clouds give a clue about shape of the cloud. 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'. ** 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; []
