10. Your plan - describe in as much detail as possible each instrument you have included in your plan. Be sure to include information on why you selected this instrument, how each one will be built, and how you would test its accuracy if you actually were to build it (maximum words: 500)

[We need 1 compass, an anemometer, cloud chart, barometer, sling psychrometer, rain gauge, and 2 thermometers. We will throw grass up into the air and use a compass to determine the wind direction. We have used this method in sports and have found it to be accurate. You can determine A the wind direction before it falls to the ground. Professional golfers use this method. The anemometer (cups around a center pole on a stand9 will be used to determine wind speed. A cloud chart will be used to determine the cloud type. We will decide what percentage of the sky is covered in clouds by looking as far as we can see in all directions, divide the sky into sections and make an estimate about how much is cloud covered. One thermometer is going !to be placed at ground level the other will be at eye level to measure 0Atemperature. A barometer (measures air pressure), sling psychrometer (Two thermometers are on a rod - one thermometer is a wet-bulb reading because gauze is wrapped around the thermometer and dipped in distilled water, the other is a dry-bulb reading. You then use a chart to determine the humidity), and a rain gauge (measure precipitation) will be used. We will place one thermometer in the shade and one in the sun. The wind speed and most of our measurements will be taken in the middle of the baseball field. To insure accuracy we are going to compare our readings with the readings of the previous classes and also use online sources and the Weather Channel.]

11. How do you know that the cost of the materials to build all of your instruments will be under \$100.00 (maximum words: 200)?

[We used the Sargent Welch catalog and actual purchase price (recent purchases) to get our costs. D Barometer (\$10), 2 !thermometers (\$14), , compass (\$10), sling psychrometer (\$15), cloud chart (\$10), and rain gauge (\$1 on sale at Franks), and an anemometer (\$30)]
