__ [] __ 4. Complete the following chart:
 * || ==== **High Pressure** ==== || ====** Low Pressure **==== ||
 * Air movement (up or down) || up || ​ down ||
 * Temperature of air || ​down || ​up ||
 * Wind movement at ground || ​ low || . high ||
 * Expected weather || . high || . low ||

** 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.

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. A 2. Warm air mass - cool air mass moves in. B 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. 6. When the front passes, the weather turns cooler. 7. Farmer Brown prefers this type of front. B 8. Usually happens and is over with quickly.
