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 include a thermometer, a rain gauge, an anemometer,a sling psychometer. We selected these instruments because we feel they are the most important intruments that we would need to learn about weather. All of the intruments we need are already put together. The thermometer measures temperature. The anemometer measures wind speed and a thermometer measures air temperature. Our rain guage measures the amount of precipation. The sling psychometer measures humidity. In order our ensure that our readings are accurate we will take more than one reading and then compare to the dopplar radar and other readings taken 2 miles from our school by the National Weather Service. We feel that it is nessecary to measure wind speed once an hour. We would measure precipitation one time everyday. We fee!l that the humidity should be measured once a day and we would measure wind direction one time every hour. We will these measurements standing by our flag pole. The flag is on the west side of the school with an open field on the other. In the rare occation of southeastern winds we would move farther into the field. A barometer will be used to measure air pressure. We will compare our readings to readings from the National Weather Service. Ours is a Pascal 3-Scale barometer to show mercury, centimeters and millimeters of pressure. A We will use a cloud chart from our text book to check cloud type. We will also judge the amount of cloud cover. We will use our flag to find out wind direction, as a wind vane. All of our readings will be taken at least twice at every reading for checking accuracy. Data will be recorded in a log and displayed.]

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)?

[All of our equipment would cost $96.30 if bought from Frey Scientific catalog.D Outdoor thermometer: $5.95 Anemomter $27.50 Sling Psychrometer $5.95 Rain Gauge $11.95 Barometer $44.95 Our rain gauge is made of plastic and looks like a funnel. It collects the amount of precipitation in the air over a period of time. It is about 8 inches tall. The anemometer is about a foot tall and would have to be placed on a fence to keep it up off the ground. 0AOur sling pyschometer measures the humidity by taking dry and wet temperature readings at the same time. It is about 6 inches long. The thermometer is mounted in a frame and can be left outside, attached to the fence.]

Optional: If you have sketches or drawings and they are in digital form (GIF or JPEG format is best) and your e-mail allows attachments, please send them to ptkww@edc.org - please be sure to include your e-mail address and school name so we can match them with the information you entered on this form. Alternatively, you can fax them to PTK Weather Worlds Designing for Data at (212)-633-8804. Please include all the 11 items in your fax so we can match it with your e-mail or form submission. However, please note that anything sent in via fax will not be able to be sent out to other classes for review - only electronic submissions via e-mail or web form will be shared in the next step of this project.
