"I took black and white samples and put them outside on pieces of insulation," explained the 11-year-old Grade 6 student from Redcliff Middle School. "I checked the surface temperature and the temperature under the sample each day and the black was warmer. I could even feel the difference. The snow also melted off the black faster."
She said through her research she found buildings in warm places often had light-coloured roofs. She is now interested in learning about the efficiency of different types of insulation.
Jason O'Brien Fisher's imagination was captured by a YouTube video of a "perpetual motion machine," made of household materials, its makers claimed could generate electricity.
"I decided to recreate what they had done because I like the idea of clean energy for the world," said Jason, 13, of Central Colchester Junior High. "I couldn't generate electricity, though, because the wheels didn't turn."
He suspects the video might be a fake, with a battery connected somewhere to make the wheels turn.
"There were a lot of comments from people who tried to make one and couldn't get it to work," he said. "Something like this might work if you had a monopole magnet, but they don't exist."
The Chignecto-West Regional Science Fair was held at the Dal AC campus and included 124 students from 13 schools.
