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 have chosen 2 thermometers, a barometer, sling psychrometer, rain gauge, flag, anemometer, a cloud chart, and a disposable camera as our instruments. For the temperature we will take it outside in the baseball field and when the sun is out. For a thermometer we will use two science lab therometers because it is better than a regular thermometer and the science lab thermometer is more accurate and more professional. We will compare our temperature with the temperature for Hazlet on the Internet on a weather web-site for a more accurate reading. We will measure air pressure with a barometer. The barometer is something that is easy to use. It can tell you the air pressure. The barometer does not change every day and it can tell you if it is going to rain or if you will have fair weather. To find out our accuracy of the air pressure we would use the Weather Forecast on the Internet. Also we could watch the morning forecast. We think that our barometer is the most accurate we could get without going over our limit. We will use a sling psychrometer to measure humidity. A slip psychrometer has a bar that connect two thermometers. One of the thermometers is used for a dry-bulb reading the other is for a wet-bulb reading. You then use a chart to find the humidity. We will use the Internet to prove accuracy. We will measure the humidity outside. We will use a rain gauge to measure the amount of rainfall. We will measure rainfall in centimeters. We will use the Internet to check our accuracy and place several rain gauges in different places. We will use the flag to get the wind direction. We will use a compass to find magnetic north and then find out which way the wind is going by the blowing of the flag. The anemometer is to determine wind speed by setting it in the open field away from the school. We chose the flag to save money. We used the anemometer to find wind speed and directions because we didn't have many choices to choose from to use for wind direction. We are going to use the camera to take pictures of the clouds to compare each day. The cloud chart so we can tell what kind of clouds they are. Then we will record them. We know this is accurate because we will take our time to do this correctly.

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 the actual prices (some of our instruments were purchased in the last year) to get our prices. 2 thermometers - $14.00, a barometer - $10.00, sling psychrometer - $15.00, rain gauge $1.00 on sale at Franks, anemometer - $30.00, a cloud chart $8.00, and a disposable camera $9.00
