2012 Canada-Wide Science Fair:


Electrolytes

Student: Aaron Prosper

District/Region: Mi'kmaq First Nations

Event: 2012 Canada-Wide Science Fair

Grade 10 - Eskasoni High School

My project is about electrolytes and how they affect the body. By taking urine samples I measured the different electrolyte levels in people. These samples helped me to determine what the usual or normal electrolyte levels were for a person. How much they would lose during cardiovascular fitness. And how well things like Gatorade could sustain or at times increase a person's electrolyte level.

Cold Play: What will keep the puck cold for the entire play?

Student: Terra Lanteigne

District/Region: Halifax Region

Event: 2012 Canada-Wide Science Fair

Grade 8 - Bedford Academy

Warm ice hockey pucks bounce randomly while frozen pucks are more predictable. I experimented with different puck designs to keep the puck cold, and therefore reduce bounce, for a longer period of time. Rebound property of each puck was measured with a homemade apparatus. Most of the experimental pucks had an increase rebound after 15 minutes, yet all performed better than the NHL Regulation puck.

Creative Capacity: Discovering the Education Path to Divergent Thinking

Student: Briony Merritt & Ellen Withers

District/Region: Halifax Region

Event: 2012 Canada-Wide Science Fair

Grade 12 - Citadel High School

This investigation examines the retention of divergent thinking within the Canadian education system. Studies suggest that children contain the ability to think 'divergently', but flaws in schooling methods cause them to progressively lose this skill. This experiment aims to determine whether the International Baccalaureate program, private schools marketed as 'creative', or a standard Nova Scotia diploma program harnesses better divergent thinking in their students.

Fruit Flavour: The Double Benefit of Aroma Volatile Treatments

Student: Ellen Song

District/Region: Annapolis Valley Region

Event: 2012 Canada-Wide Science Fair

Grade 12 - Horton High School

The benefits of aroma precursor treatments were investigated in blueberries and apples. It was found that although the different fruit produce different aroma volatiles, the aroma is still greatly improved and enhanced. By inoculating apples with fungi and treating them, it was also discovered that precursors have an anti-microbial effect. This has great commercial application as fruit aroma is enhanced and decay is inhibited.

Improving Ear Protection

Student: Alexander Sapp

District/Region: Halifax Region

Event: 2012 Canada-Wide Science Fair

Grade 10 - Fountain Academy of the Sacred Heart

A computer run test was used to prove that there is not a direct relationship between the amount of ear protection used, and sound localization capabilities (it matters where the protection is positioned). Response times for front/back sound localization were shown to be greater than response times for left/right sound localization. Subjects were shown to have low front/back sound localization capabilities with standard ear protection.

The Problem with Pickerels

Student: Juliana Ali

District/Region: Chignecto Region

Event: 2012 Canada-Wide Science Fair

Grade 10 - Northumberland Regional High School

The invasive species, chain pickerel (Esox niger), can survive in waters with the salinity of up to 15ppt (Scott, W. B. and Crossman, E. J., 1973). Due to the high salinity tolerance of chain pickerel there is a concern that they could withstand the salinities of an estuary long enough to travel from one river to another using the estuary as a pathway.

Wind Turbine Efficiency

Student: Nicole Moulaison

District/Region: Tri-County District

Event: 2012 Canada-Wide Science Fair

Grade 9 - Digby Regional High School

As time goes by more wind turbines are being built as an Earth friendly and sustainable way of producing electricity instead of burning coal. Which is very wonderful, but in my opinion, the design that companies most commonly use is not as efficient as they could be. So I tested six different designs, including my own, to see which was the most efficient.
