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
 * ** 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.

** 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.

** 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 visible mist of billions of water and ice particles floating in the sky. ** 2. Explain how clouds form.** Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets. The water droplets then form a cloud. ** 3. What are the 3 "families" of clouds and what do their Latin names mean?** altocumulus means middle height and heap & Cumulonimbus ** 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; []

**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.a 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.b 7. Farmer Brown prefers this type of front.a 8. Usually happens and is over with quickly.b
