20 -- PORT PERRY STAR -- Tuesday, April 11, 1969 Years from now, we may be calling 16 year old Leanne Philip "Professor" or maybe "Doctor." One thing's for sure, Leanne has cornered the market on winning at the Durham Regional Science Fair. For the third year In a row, she has claimed first prize. See story for details.

Leanne Philip. The 16 year old Port Perry High School student has once again won first prize at the Dur- ham Regional Science Fair and has earned the right to repre- sent Durham at the Canada Wide Science Fair competition. It will be the third year in a row this intelligent, deter- mined and well-spoken teenag- er will go to the nationals. Last year she travelled to Winnipeg and came home with a coveted bronze medal for the best physics project in all of Canada, as well as $450 in cash. At the Durham fair this year, she won the gold medal in Sen- ior Physical Science; the GM of Canada award as the best Sen- ior Project at the fair; the Grand Prize as the Fair's Best Project; and an all expense paid trip to the Canada Wide Science Fair in St. John's Newfoundland from May 13 to 21st. All this, and she was u against competition from 1956 other projects. Of course, the competition will be even tougher at the na- tional level. Last year, for exam- ple, Leanne's project was com- pared to 300 other entries from all over the country. And de- spite it all, she won the bronze. This year, in Newfoundland, she'll be in the senior level of competition rather than inter- mediate, but chances are she'll still come home with a medal. It could very well be gold. She giggles and blushes a bit at this thought, but admits she is hoping. Leanne says this may be the last time she enters Sci- ence Fair competiton (next year her school workload, in Grade 12 with several O.A.C. courses) will be a lot heavier), and she'd VY VV VYYVIVIVyIVYyVYVYVYVIVYVYSY VY YY VY VV Y VYY YY VEYVYVYVYYYSYYVYIVYVYY vvvvevvevevvveyevel vv Grand Opening Weekend [5 So Friday April 14 to Sunday April 16 ane sev] Free Cofee Free Gift with Punchase [Lovins Vg Yo wn v gs X50 Enter own draw for a band-crafted wneatk rR 0 (Approx. retail value $55.00) fey vr] Meet the Mayor Saturday at noon at reve Yl own nibbon cutting ceremony po eve 10% a KR '0 off our handcrafted, SN Cal re decorative wreaths & hats py Nd Pamper yourself with our extensive [oie wre) selection of imported bath items Foe] XP Come in & browse through our pre] os large selection of country gifts vrs VY VY VP PPV YN OPV V IY "e v v . pF v vv vv v v hd bk vv v vv / v v ¢ IA\OoUnN reailvions |.-:- Pi . v pv v vv ¢ v v 16 : Fr v vv v .

"I'd love to do more next year. Realistically, I.don't think I can," she said, and then smiled. "But that's what I said last year." Once again, winning Science Fair project studies the impact of substanc- es used to melt road ice and snow. It has been her theme for the last four years. It all started when Leanne was in Grade 8 and the teacher said, "You have to do a Science Fair project." She didn't know what do do, so she asked her father, R.H. Cornish math teacher Reg Phil- ip. "Dad said, you have to doit on your own," she recalled. "So one day I was walking home from school, charging through the snowbanks and getting really mad because of all the sand in the snow and what a mess it was." And that's when the idea struck her.. Her first project dealt with the effect of sand on snow and ice removal. The next year, she stayed within the same theme, but crossed over to another winter de-icer, road salt. She compared the differences between two types of salt, sodium chloride and calcium chloride (she dis- covered the sodium version was more efficient). Last year, she compared the efficiency of various grain sizes of sodium chloride (and decided smaller grains worked best). After last year's Science Fair she continued her research, working for the Ministry of Transportation and Communi- cation (how many 15 year olds can get jobs in the Ministry's re. search department?). While she was working there, Leanne was introduced to an ex- perimental chemical manufac- tured in Seattle called CMA (Calcium Magnesium Acetate), which could, in the future, be used the same way road saltis. Leanne was intrigued, and decided to make CMA the focus of her Science Fair project his year. CMA, she says, isn't available commercially yet, but it has 'many benefits road salt doesn't. It is made from garbage and her award-, limestone, of which "there is plenty in Ontario." Calcium oxide and magne- sium oxide are combined with the acetic acid drained from garbage. The end result is in pellet form that Leanne says smells like vinegar. She says the biggest benefit of CMA is its lasting power. Salt can dissolve ice within 12 minutes but it washes away within a day. CMA, on the other hand, takes longer to dissolve the ice (between 28 and 50 min- utes) but it stays on the roads up to three days. "It breaks down the ice and actually sticks to the road," she explained. "It won't be swept off into the ditch." Studies to date have labelled CMA as inert, which means it won't corrode metal the way salt can. And Leanne claims that CMA won't contaminate the environment. "There hasn't been any long term studies yet, but so far it looks like CMA doesn't contami- nate water, it doesn't stunt veg- etation, and it virtually causes no problems with the environ- ment," she explained. The only problem with CMA is its price. Leanne said salt sells for $356 per metric tonne, while CMA costs $1,200 for the same amount. ~ She says the high price is "pure shipping costs", and if a plant was to be built in Canada, the price would come down to $400 per tonne. Still more ex- pensive, but because it won't corrode cars or bridges, and be- cause it won't harm the environ- ment, she says it is the cheap- est form of de-icer in the long run. She says the chemical will eventually be used, "Not in the near future, but in the future. I don't think they'll use it right . away because they've used salt for about 40 years." She adds," I wouldn't want them to use it right away, like next year, either. There are still tests tobe done." Although the Ministry is studying CMA, Leanne says her own research, the physics end of it, is different. Obviously, the Ministry is keeping a keen eye on herwork.
