A good chemistry show can open the minds of young people to the wonders of science. A fiery explosion or two helps.
The University of VictoriaB次元官网网址檚 Chemistry StudentsB次元官网网址 Society is hosting a show on Thursday that promises energetic and colourful chemical reactions, while raising money for the United Way of Greater Victoria.
UVic chemistry professor Alexandre Brolo is leading the demonstrations, and is following in the long tradition of retired professor Reginald Mitchell (a.k.a. Dr. Zonk), who held science shows for kids since the mid-1970s.
B次元官网网址淲e donB次元官网网址檛 dress up (like Dr. Zonk), but we try to make a lot of chemical reactions that are visually appealing, especially ones that will get the kids exciting and curious about science,B次元官网网址 Brolo said.
The experiments progress from basic reactions like those that produce colour changes in a liquid, to spicy concoctions that generate masses of growing foam, to experiments that rapidly shrink Styrofoam cups.
The perennial favourites are things that go boom, which is where the ethanol cannons and hydrogen balloons come in.
B次元官网网址淗ydrogen balloons explode very loud. But if you mix hydrogen with oxygen, they explode much louder,B次元官网网址 Brolo said laughing. B次元官网网址淚 like the explosions. They get the most response from the audience. Everyone likes a good explosion.B次元官网网址
Brolo has taken the helm of the chemistry show for about four years, but heB次元官网网址檚 an old hand at wowing audiences. He did similar shows in his native Brazil in the 1980s.
B次元官网网址淭he main thing is to make science interesting and enjoyable. With kids who are young, we want to wake their curiosity, to ask questions and understand the phenomena theyB次元官网网址檙e looking at can be explained.B次元官网网址
The chemistry show is on Nov. 22, 7 p.m. at the Bob Wright Centre at UVic. Entry is $9.50 with proceeds going to the United Way.
