Congratulations to our Canada Wide Science Fair (CWSF) Students of 2025!

Our 2025 CWSF Students will be heading to Fredericton, New Brunswick to compete at a national level with their amazing contributions to student science!

Many people with allergies and skin irritations cannot use factory-made lotions due to their stabilizers and additives. We are on a journey to find and make a pH balanced, hydrating lotion that prevents moisture evaporation, while being non-allergenic.

Cars driving over snow on winter roads cause the buildup of ice. To ensure safe driving conditions, gravel is often spread to increase traction. However, this treatment is ineffective, leads to damaged windshields, clogs storm sewers, and contributes to severe air pollution. As an alternative, salts can be used to melt ice through the process of freezing point depression.
In my project, I studied salts and three commercial products, and how their concentration and temperature affect their ice-melting effectiveness. I conducted: 1) small-scale experiments on homemade ice to measure the amount of melted water; 2) large-scale experiments on streets to visually rank their effectiveness; 3) freezing experiments to evaluate their ability to delay or prevent freezing; and 4) pH tests to measure the acidity or alkalinity of the melt.
Most chemicals and all commercial products were able to melt ice, with higher temperatures and higher concentrations increasing their effectiveness. Magnesium and Calcium Chloride, which have the highest reactivity, and the commercial products containing these salts were the most effective, even at very cold temperatures. To expand this experiment, I would like to study the environmental impact of salts and methods of recovery from culverts in spring.

Due to increasing summer temperatures, artificial birdhouses may increase juvenile bird mortality. We tested ways to reduce temperature fluctuations in artificial bird houses. Specifically, we did an experiment to test how aspect, colour and wood type affect the temperature in artificial bird houses.
