Jessie Fournier (left) and Johanna Clerjuste – both Grade 8 students at Lester B. Pearson Catholic High School and Blackburn Hamlet residents – studied the effects of different types of music on plants’ growth – using rock, pop and classical music as well as a silent control group. They found that radishes, beans and marigolds preferred the classical melodies, while the cosmos grew better with rock tunes. - Jessica Cunha/Metroland

Fourteen-year-old Bhavya Mohan swept up a number of awards at the Ottawa Regional Science Fair, held March 31 and April 1.
The Grade 8 Earl of March Secondary School student created a DNA measurement tool that can be used to detect cancer cells. The tool is “a portable, efficient and cost effective diagnostic mechanism” that could be used in developing countries, he said.
“I've designed a DNA measurement tool which can facilitate the same diagnostic as a Nanodrop,” said Bhavya.
A Nanodrop is a medical machine that allows the analysis of minute samples and costs upwards of $10,000.
“Nanodrops cost tens of thousands of dollars while my device only cost me $1 to fabricate. (With) $1 I was able to measure the amount of DNA and also be able to tell if a cancer was present or not,” said Bhavya.
Current diagnostic tools often require specialized lab equipment, are expensive and time intensive, he said.
“In the real world, this device could be used in Third World countries to help more people be able to diagnose diseases,” said Bhavya. “This device could be used to promote more early diagnosis.”
His project, titled “Development of a Novel Lab on a Chip based PCR Sensor for Disease Diagnostics,” took home a number of distinctions at the regional science fair including:
• First place Interdisciplinary Award in the junior category;

Bhavya is one of 11 students who will travel to Regina, Sask. this May for the Canada Wide Science Fair.
More than 180 students, in grades 7 through 12 and from schools across the city, displayed their science projects at the 56th annual Ottawa Regional Science Fair held at Carleton University.
Portable Solar Still
Barrhaven residents Mingde Yin and Aditya Prashar — both Grade 10 students at Colonel By Secondary School — created a portable solar still to turn contaminated water into safe drinking water.
Their model “makes clean drinking water 100 per cent of the time,” said Mingde.
And the still, unlike water filters that have to be replaced, can be used an infinite number of times, added Aditya.
Their portable, compact solar still cost less than $7 to make and could be used for humanitarian aid and commercial uses, they said.
Mingde and Aditya took home two awards and an honourable mention:
• an American Society of Heating, Refrigeration and Air Conditioning Engineers intermediate award (includes $200 cash prize);
• an Ottawa Regional Science Fair Committee — Consumer Products award (includes $75 cash prize);
• and an Interdisciplinary Award honourable mention in the intermediate category.
Hockey Helmets
Mimi Braiter, a Grade 7 student at Ottawa Jewish Community School in Nepean, said she wanted to research ways to lessen concussions in hockey — a sport her brother plays.
She conducted studies to prove hockey helmets should have a soft protective layer on the outside of the hard shell to help lessen concussions in players.
Mimi used gel packs, sponges and bubble wrap to test her theory, and all three lessened the impact more than a regular helmet, with gel packs absorbing the most impact, she said.
Mimi won an Independent Health Science Research award with a $100 cash prize and an Interdisciplinary Award honourable mention in the junior category.
Salt and sprouts
Grade 7 Ashbury College student Xander Fallis studied the effects of salt run-off on farmers’ crops by using magnesium chloride and alfalfa sprouts, winning a third place Interdisciplinary Award in the junior category.
Too much of the chemical killed the plant while a small amount “is healthy for the plant and boosts the plants growth rate,” he said.
Xander plans to expand his project over the summer to study if the solution could make crops grow faster, have more than one harvest and taste the same, he said.
