2/9 Element Practice 11-20

2/13 - With what you know about North pole, South Pole, the equator, and the relationship of air pressure and temperature, make an hypothesis about how the winds should move across the surface of the Earth.

2/14 - Using the cyclone simulator:

Hold and carry the simulator by the connecting piece in the middle.

(1) Turn the Cyclone Simulator upside down.

• • Make at least three observations.

  • Make a hypothesis - Why is the water flowing so slowly?

(2) Do it again. This time experiment with ways to make it flow faster by shaking, sloshing and twirling.

• • What did you do to make it flow better?

  • Make at least 3 observations now that it is flowing quickly.

2/15 - Compare the surface weather map and weather data visuals in the following two links to answer the questions below:

• Current US Surface Weather Map - weather.com

• Current Surface Wind and Temperature - earth.nullschool.net

1. What direction are high-pressure systems rotating (clockwise or counterclockwise)?

2. What direction are low-pressure systems rotating (clockwise or counterclockwise)?

3. Pick a high-pressure and low-pressure that wind streamlines are going between. Describe how the wind changes direction and speed as it moves between them.

4. The coldest temperatures are dark blue going to the warmest as red. Describe how temperature changes between your high and low pressure systems.

5. On the Surface Weather map, look for a line coming out of a low-pressure system that represents a cold front. Compare to the data. How does the wind direction and speed change along a cold front?

6. How does temperature change across the cold front line?

Objectives

Atmosphere

• Identify the four lowest layers of the atmosphere and what defines those layers.

• Describe the effects of the ozone layer and greenhouse effect on the atmosphere and global warming.

• Summarize the three methods of heat transfer.

  • Explain how energy provided by the sun causes atmospheric movement called wind.

• Explain the key factors that cause global winds

• Describe how convection causes sea breezes, land breezes, mountain breezes, and valley breezes.

  • Create Isotherm and Isobar map weather maps from data.
