HI td cin lh i Ati. di di da i didi Leanne Philip spent a lot of very cold nights last winter studying the ice on the driveway at her folks home in Port Perry. It was all in the name of science, however, and for this grade nine stu- dent at Port Perry High School, the countless hours and the cold hands were worth the effort as she was awarded the Grand Prize for her project at the Durham Region Science Fair held recently in Oshawa. It is believed Leanne is the first ever PPHS student to win this prestigious award, and she has also earned herself a trip to the Canada Wide Science Fair which starts May 10 at the Erindale Campus of the University of Toronto in Mississauga. As well as winning the Grand Prize against some 200 entrants at the Durham Science Fair, Leanne's project placed first on the In- termediate Physical Sciences Department, and she was awarded one of the special prizes, courtesy of General Motors. - While Leanne told the Star last week she is absolutely thrilled and delighted at winning the awards and . the chance to attend the Canada Science Fair for a week, "it all came as a surprise to me. I really was not expecting to win." Leanne's project is titled "Yee Man Comes. Ice Man Goes," and it involved a very detailed examina- tion of how salt melts ice on the roads in winter. More specifically, ak Leanne wanted to determine exact: ly how much salt is needed to melt road ice under certain kinds of weather conditiions. ~ Her project was several months in the making. She actually started it last year for the Grade 8 Science Fair competitions and she kept 3d- ding to it over the past winter. Using both commeon table salt and calcium cholride (the salt which is spread on the roads in winter) Leanne conducted 24 different ex- periments, and to guarantee the highest possible degree of accuracy, she repeated each experiment three times. . And because she hopes eventual- ly that the experiment will have some practical use in determining how much salt should be put down on the winter roads under all kinds of conditions, Leanne's "laboratory" was the driveway in front of her house. It was cold work putting the salt on the driveway ice, then taking all the necessary readings and measurements, often late into the night. "The neighbours must have thought I was a little crazy," she said with a smile. Not surprisingly, she found that calcium chloride works better as an ice melter than ordinary table salt. Leanne plans to continue working on the experiment next winter. And the Durham Region Roads department has expressed an interest in taking a look at the conclusions once the ex- periment is over.' Leanne is a Grade nine student at .-Port Perry High School. Her best subjects are science (naturally) but she manages to knock off A's in the others as well. She hopes to pursue a career in science after taking degrees at either Queens or the . University of Toronto. She admits the Science Fair pro- ject took up a great deal of her time, but the rewards are obviously worth the effort. As one of four 'students from Durham Region selected for the Canada wide Science Fair, Leanne 'will spend the week (May 10-17) at the Erindale Campus with young science buffs from all over the country. When they are not talking science, the students will be taking in the sights of Toronto and southern On- tario, including a trip to Niagara Falls, tours of the CN Tower, the Metro Zoo and the Stock Exchange, all expenses paid. And there are nice cash awards for the winners in the Canada Science Fair. Leanne says her examinations of how salt melts ice is just really beginning. She hasplans to continue the experiments over the next three lor four years. ~ ALL TYPES -- ALL MAKES -- STEREOS & HI-Fi's MODULAR 4 SERVICING THIS COUPON WORTH $5.00 OFF YOUR NEXT SERVICE CALL! 214BLOORST.E. | 723-5341 PARKSIDE 13:4 e FmUPS RCA IENTH OS HEA HTAGH LOVES Country Conner Ceramics Buy a piece of Greenware from our store during the month of May and get 'FREE FIRING' 81 Lilla St, Port Perry 985-9508 Ice has melted for now, leaving behind cool prize So some cold night next winter if you happen to pass the Philip residence in Port Perry and you see Leanne all bundled up peering in- tently at the driveway, you'll know what she is doing. Several other students from Port Perry competed in the Durham Region Science Fair held recently. Scott McCullough and John Stark of R.H. Cornish placed second in the Grade 8 physical science category for their experiment on Food Col- . ours and Evaporation. In the Grade 7 engineering category, Laura Justynski of R.H. Cornish was awarded a third place for project on Wind Power. Careen Lawson of R.H. Cornish won an award from the Federation of Women-Teachers of Ontario for her project on Flame Retardation, while Scott McCullough and John Stark received an award from the Ontario Teachers Federation. PORT PERRY STAR -- Tuesday, May 5, 1987 -- 9 Leanne Philips, a grade nine student at Port Perry High School has won a trip to the Canada Wide Science Fair starting May 10 in Toronto for her project on the melting of ice. It was judged best project at the Durham Science Fair. Leanne spent countless hours this past winter working on the detailed experiment.

R " ©o © © ! about heating your home Oil furnaces manufactured since 1979 have an'efficiency rang of approximately 85%, while a new conventional gas furnace is only 62% efficient. : OIL HEAT IS MORE ECONOMICAL B The cost of heating oil reduced by 22% from February 1986 to February 1987. In that same period, the cost of gas reduced by only 1.4%. w "g OIL DEALERS ARE COMMITTED TO LOWERING YOUR HEATING BILLS. If you're considering converting, the typical cost of a conventional gas furnace i 1S $1900. You can get greater efficiency by upgrading your present oil system for less than $600. A new high efficiency oil furnace costs less than $1700. IT DOESN'T PAY TO CONVERT TO NATURAL GAS OR ELECTRICITY Our oil fired water heater can provide an entire tank full of hot water in just 20 minutes. Compare this to the 1.3 hours it takes natural gas to heat up a whole tank. OIL IS MORE EFFICIENT Don't be mislead by the gas company's guarantee of lower heating costs. The formula they use is comparing a brand . new gas system to an old oil furnace. You can have a more efficient system for less money (than a gas conversion) by upgrading your current oil furnace. now that's a guarantee!
