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)

Our instruments are a barometer, 2 thermometers, a wind sock, compass, sling psychrometer, cloud chart, and rain gauge. Our data will be collected in the middle of the field outside our classroom. We will place two thermometers to measure temperature - one at ground level and the other at eye level. The wind sock and a compass will determine wind direction. We will see which way the wind is blowing by holding up the wind sock and determining the direction using the compass. To save on cost we are going to use the Beaufort Scale to measure wind speed. The Beaufort Scale uses the movement of the leaves and branches on the trees to determine wind speed. A cloud chart will be used to decide the cloud type. We will estimate the percentage of the sky! covered in clouds that is above the baseball field to come up with a percentage of cloud cover. The barometer will measure air pressure and the sling psychrometer will be used to measure humidity. The sling psychrometer uses two thermometers. One is covered with gauze and the other is left dry. Using a chart you find the relative humidity. A rain gauge will be used to measure rainfall. We will use several rain gauges to make Asure our measurement is accurate. We will compare our measurements to the measurements posted on the Internet and on the Weather Channel to insure accuracy. We did not have the time to make our instruments, so we decided to use the instruments we already had.

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. Barometer (\$10), 2 thermometers (\$14), a wind sock \$10), compass (\$10), sling psychrometer (\$15), cloud chart (\$10), and rain gauge (\$1 on sale at Franks)
