Show Thursday, October THE GREEN SHEET 5 24, 1985 Projects Produce Magic At Valley CUP Is Essential To Future Water GRANGER. Classes in satellite When black and white line drawings showing these physical features of the area are placed on an overhead projector, students can make their own color copies, mark lines of latitude and longitude and learn to interpret their maps. They use road maps in conjunction with their aerial views and become very familiar with map reading techniques, he noted. The fascinating thing to many is that putting three black and white maps together produces colored pictures, said the teacher. It boggles their minds that all colors mixed together produce white, he said. When you mix some of every color, you get a sort of muddy black, he noted. But, when you mix light of various colors, you get white. If you see a red - or blue or green shirt, it is because it is absorbing all the other colors and showing the red, he explained. That is why the carpet you buy looks a different color in your home than it did in the store. The fluorescent lighting in the store uses blue and green, sunlight has all the colors hence the difference in appearance in the store and in your home. Students also find it fascinating that all healthy vegetation shows red, he remarked. Fields and forests look red. Valley junior high and many homes are surrounded by red, he noted. Mr. Willie is in his third year of teaching satellite imagery in the Granite district program. He has trained 100 teachers in the use of the skill during the past three years. He has also presented programs at Utah State University, in elementary schools and at the Utah Science and Energy Conference. He designed a New World climate map for use in ninth grade geography classe, wrote the text book for his Granite Utah classes, and a workbook, Through Maps, which includes a new physical map of the state, using satellite imagery as a basis, which is geared to seventh grade Utah studies. The Valley classes are being offered to students in the GTX (exceptionally gifted) program, with 33 students involved. These are sharp kids and they find the subject fascinating, said the teacher. The enthsiasm he shows in discussing the subject is contagious and students catch that spark, finding the combination of regular maps and satellite imagery offers a new dimension in studies, shewing hidden features of geology, of light and of the world around them. It is truly magic in the classroom - a new world of color and light. imagery may not sound like the average junior high curriculum of- fering, but they are becoming increasingly popular with students at Valley junior high who, according to instructor Reynold D. Willie, find the subject not only Interesting, but at times And some of the projects used in the class seem close to magic. Students use pictures obtained from NASA and are finding it possible to take three black and white images into a compositor and end up with a colored picture. We use different bands to obtain different colors, explained Mr. mind-bogglin- g. Willie. For instance, when light passes through band 4, it goes through a blue filter, band 5, a green filter, band 7, a red filter, then the three meld together in the optics and come out as a color composite. The satellite senses reflected explained Willie. Band 4 light, looks at green, band 5 at red and band 7 sees infra-rewhich is beyond visibilty, he explained. Each band shows up different areas on a map, he added. Band 5 shows much contrast and looks into water showing indefinite boundaries, shows mountains. Band 4, with green light reflection, sees different levels in water, penetrates so you can actually see the shorelines underwater. The bands pick out natural colors, but healthy green vegetation shows as red, the teacher said. The eyes are the receptors and see what the light reflects, he pointed out. A large map shows the Salt Lake Valley area, with the different levels of the lake clearly visible in shades k from as depth changes through the years. Students can see the different elevels of the lake clearly, levels at various times from 1965, 4,195 feet, to the present 4,212. Water absorbs all light, making boundaries visible, the teacher observed. Students can locate familiar landmarks on the map and many can find their homes. Some can see that when the map was made, their home was not yet built. They can locate Valley junior high, a dark blue dot surrounded by the grass and shrubbery. red Valley Fair Mall, the Kennecott open mine, Granger high and other landmarks familiar to students can be located. Students can even trace their route from home to school. Students learn to recognize mountains, fallow fields, dry farms, desert areas, irrigated land, salt evaporating ponds, reservoirs and buildings. d -- d, blue-blac- - Maloney noted, steps were taken to TAYLORSVILLE. A business-orienteaudience was told here Thursday that voter approval of a repayment proposal is essential next month to help assure future water supplies for the Wasatch Front. That was the message delivered to members of the West Valley Area Chamber of Commerce by representatives of the Central Utah Project and the Salt Lake County Water Conservancy District. Making the presentation were Jerry Maloney, West Valley City mayor and member of the CUP board, and Matthew Marshall of the SLCWCD staff. The two provided background information relating to a special election in which voters of 12 counties in Utah will decide on a proposal to repay $335 million in order to continue with construction of the CUPS Bonneville Unit. That election is set for Nov. 19. Responding to his own question, Maloney said voter approval of the proposal will not increase the rate at which taxes are currently being paid on the CUP, but, instead, will extend the period of payment over a span. The current levy, he explained, is 1.97 mills, with the maximum set at 2.0 mills. but to There is no alternative at the the special proposal approve election, Maloney advised, stressing how totally dependent the west side of the valley is on CUP water. The west side has no stream rights, only ground water - and the best wells are on the east side of the valley, he pointed out. Maloney called attention to one of the key elements in completion of the Central Utah Project is construction of the Jordanelle Dam in the Heber Valley. Water that will fill the Jordanelle is now runnirg down the Provo River, the Jordan River and into the Great Salt Lake, he pointed out. Nearly a half century ago, PINPOINTING . . , Tamora Miller, Jeff Jordan and Benjamin Erven-in- g find Valley junior high on a satellite-generatephoto of northern Utah in Valley junior high GTX program. d assure adequate water supplies for future generations when a dam was built across the Provo River at a cost of $40 million, creating Deer Creek Reservoir. Then in 1965, voters favored by about a 13-- 1 margin to proceed with the Bonneville Unit of the CUP at a cost of about $130 million. Additional information on the matter was provided by Marshall, who said that summertime demands for water have been steadily increasing with the valleys growing population. Marshall also cited figures pointing to the degree of dependency on CUP water among local entities within the Salt Lake County Water Conservancy District. The district, which is the wholesale arm of the CUP, serves 19 cities and improvement districts in the valley. Of those, Granger-Hunte- r Improvement District depends on CUP for 65 percent of its water; Taylorsville-Bennio- n Improvement District, 40 percent; Kearns Improvement District, 10 percent; West Jordan, 60 percent.

Presented at Camp Williams in the form of the Eisenhower Cup, the award is granted by the National Guard Bureau in Washington, D. C.
