Grant Mansiere香蕉视频直播檚 science fair project, examining trembling aspens, was one of 30 projects on display in Ottawa last week.
Mansiere, a Grade 12 student at Summerland Secondary School, was one of just two British Columbia students at the exhibit in Ottawa.
He began his study on the trembling aspens last year, when he saw a grove of trees with their leaves fluttering.
香蕉视频直播淏ut there was no wind, so how could the leaves be trembling,香蕉视频直播 he wondered.
As he researched the trees, he discovered trembling aspens are a monoculture. Each tree is genetically identical to the others.
香蕉视频直播淚f an insect infestation or a fungal infestation occurs, all of these trees are very susceptible,香蕉视频直播 he said.
However, the trembling aspens have two defences against infestations.
The leaves flutter in low or no wind, and can generate enough force to fling an insect off the leaves.
Trembling aspens also have hydrophobic leaves, which repel water.
When water comes in contact with the leaves, it instantly beads and falls off. The drops of water also pick up particles of dirt or mould.
Mansiere said there is a grove of trees in Trout Creek in Summerland, where this behaviour can be observed. Anyone can pour water onto the leaves and watch as it quickly falls off.
Mansiere has had a variety of science fair entries over the years, and has attended the Canada-Wide Science Fair.

He added that he likes to take complicated scientific material and find ways to present it to various audiences, from those with no scientific background to those who are knowledgeable about the subject.
