At the end of the first couple of rounds,
Each of the school’s five eighth graders had correctly answered most of the initial 40 questions that had been posed to them during the annual “You Be The Chemist Challenge” recently at Moraine Valley Community College.
After the third round, the contingent from Conrady was still going strong among the 23 competitors from six schools.
Conrady’s team consisted of Faisal Al-Qawasmi, Max Bauer, Rick Korolewicz, Arnas Liesis and Matt Stoch. Science teachers Becky Glaubke and Matt Offord worked with the students after school for the last few months.
While the five performed well in the competition, Matt Stoch did well enough to place third, which ensured him a seat at the State competition on April 27 at North Central College in Naperville.
The five from Conrady were selected from among a group of more than 20 of their classmates who participated in an after-school study group preparing for the chemistry challenge.
Matt, Faisal, Max, Rick and Arnas were selected based on the results of a test the group took that was provided by the Chicago Drug & Chemical Association, which sponsored the event.
Students were asked questions such as: “Which of the following are phase changes between gases and liquids,” with the answer being condensation and evaporation.
A follow-up question was: “A substance may undergo a phase change as a result of changing which of the following?” The answer was pressure.
Another question was: “Why is salt thrown on sidewalks in cold weather?” The answer was is that salt lowers the freezing point of water.
One last question that was posed to the students included: “Which is not a physical property?” The answer was electronegativity.
