6 THE NEW TANNER THURSDAY, APRIL 14, 2005 St. Joseph students win big... Continued from page I Brown said they decided on the experiment after reading several articles with opposing opinions on whether violent video games cause increased aggression in kids. "Grade seven students Jen- nifer MacDonald and Amy Brierley tempted their fellow students with several tasty burgers -- and found the health- ier ones were the hits. Their project " What Lies Beneath... Your Burger" earned MacDonald and Brier- ley Bronze Merit Award and a Dofasco Commercial Depart- ment Award. "We made four burgers with healthy nutrients in them and kids in our class tested them," said MacDonald, adding the burgers included one with apples and carrots, one with asparagus and broccoli, one with bran flakes and molasses and one with ground meat. "The kids liked the one with the apples and carrots best," Brierley said, adding although there are veggie burgers at some fast food menus, there isn't a burger that provides the nutrients of their burger and still tastes good. Grade eight students Mike Brown and Shane Carr.earned a Bronze Merit Award with their experiment "Battle of the Battery Brands." "We tested five brands of AA mortgage 0 ot application.

"We found Energy e2 lasted longest, and Duracell actually had a slightly better cost efficiency, by a small margin, but the Energizer e2 was the best battery to buy because it lasted the longest and per minute of usage it was cheapest," Brown said. The parents of Steven Slow- ka acted as guinea pigs for the experiment that he and his partner, Sarah Nicholson, car- ried out on sodium intake. The grade seven students convinced the Slowkas to double their intake of salt for a week so they could be tested for its impact on their blood pressure. The experiment "Are You Eating Too Much?" earned the students a Silver Merit Award anda first place in the Acquired Brain Injury competition. "We wanted to design a study to look at one of the ma- jor causes Of heart attacks and that's high blood pressure," Slowka said on Monday. "We doubled their intake of sodium and then took their blood pressure every night," Nicholson said, adding the impact of sodium intake is very different for everybody. It can be altered by many things, including physical activ- ity and whether you watched a sad movie that made you cry. When the Halton Catholic District School Board released results of the Science Fair last week, St. Joseph Principal Gail Rutherford said she was "over the moon" proud with the accomplishments of the students. "T said to my superintendent 'I'm just splitting -- I have to tell somebody'" Rutherford said on Friday. ~ Rutherford said much of the praise for the students' Strong showing goes to Sci- ence teacher Mrs. Elizabeth Romanowicz who resur- rected the school's science fair last year. "We hadn't had science fairs for a few years because they are a lot of hard work, but Mrs. Romanowicz thinks they are extremely important in helping the kids really ap- ply what they have learned and made it happen," Ruth- erford said on Friday. On Monday, Romanowicz said she has a passion for science, but it is the students and their parents who deserve the praise. "The more | learned about science, the more I was in awe -- you know how won- derful God's world really is -- that's what gets me going," Romanowicz said. "The role of a teacher is to instill in kids a lifelong love of learning, if I just at least sow the seeds of that, then I've done my job." %) Acton af Introduction to Yoga/Pilates Proud member of the Canadian Jiu Jitsu Associations Jiu-Jitsu Martial Arts and Self Defence for Adults & Children Sunday, April 24° 9am-tpm " $49 per person Everyone Welcome!

METALLURGICAL MIGHT: An experiment welding dis- similar metals together earned Acton's Joseph Querques top honours at the recent Bay Area Science and Engineer- ing Fair. Querques, a Grade 10 student at Christ the King Secondary School in Georgetown, is one of 20 Canadian students to advance to the Canada Wide Science Fair in Vancouver in May. - Frances Niblock photo Acton student earns top award at Bay Area Science Fair As far as Acton's Joseph Querques is concerned, when it comes to metals and their alloys, the combina- tions are endless and finding them may lead to what promises to be a brilliant career as a metallurgist or materials engineer. Querques, 15, is a Grade 10 honours student at Christ the King Catholic Second- ary School in Georgetown whose project " Metals and their Weldability" earned him a trip to the Canada Wide Science Fair (CWSC) in Vancouver from May 15 10.23: Querques' project was en- tered in last weekend's 45th annual Bay Area Science and Engineering Fair, spon- sored by the Ontario Trillium Foundation. Almost 400 students vied for $175,000 in prizes -- cash, gifts and trips --and 40 students advance to the Nationals -- including Querques and his younger brother, Nicholas, a student at St. Joseph Catholic School who, with partner John Spehar, entered a winning project on batteries. Querques said in industry today there's a great need to weld dissimilar metals to- gether, such as in the aircraft industry where more alumi- num is being used because of its lightweight properties, but carbon steel is still being used because of its strength, but, they can't weld them together because they are dissimilar metals. "So, what I tried to do was weld dissimilar medals together using appropriate filler to test if the weldment -- the area where the medals are actually being weld- ed together -- is stable and shares the same base medal properties as the medals it was originally welded to," Querques said on Sunday, taking a timeout from his homework. Querques said with the help of a mentor at Cones- toga College he chose four metals in common use in industry today -- carbon steel, 5,000 series aluminum, 304 series stainless steel and electronic tough pitch cop- per -- and attempted to weld them together. "| was looking at the alloy- ing properties of metals and how the crystalline structure can be used to actually weld dissimilar metals together," Querques said, adding he discovered that high thermal conductivity rates of alumi- Continued on page 8 GAP ei sunshinekidswear@ OF KOSH TOMMY HILFIGER Nike ..ADIDAS. ..-PLUS MANY MORE DESIGNER NAMES GENTLY USED CLOTHING INFANT TO YOUTH SIZES é _ a SPRING & SUMMER SALE ONE DAY ONLY SATURDAY, APRIL 23", 2005 0 12-3:00 pm ACTON ARENA ma a 415 QUEEN ST.
