2022 4-H Canada Science Fair

At the 4-H Canada Science Fair, finalists showcase their projects, have the chance to meet with their peers, exchange ideas, and take part in activities and workshops that foster their knowledge and interest in STEM.

This year, four 4-H members came together virtually from across Canada for their chance to earn the top honour within 4-H Canada Science & Technology Pillar programming. For months prior, our finalists had been exercising their curiosity and demonstrating determination as they worked hard to complete their science fair projects. Each of them exemplifies the problem-solving and leadership skills 4-H’ers are mastering across the country within areas of science, technology, engineering, math, and agriculture.

The 2022 4-H Canada Science Fair took place from March 3 to 7, 2022.


Winners of the 4-H Canada Science Fair will move on to the virtual Canada-Wide Science Fair in May 2022, where they competed against the best and the brightest from across Canada!

Do Cattle Impact the Canadian Grasslands

If you ask anyone what the most endangered place in the world is, they will probably say the oceans or the Amazon rain forest, but the most endangered place in the world is the Canadian grasslands. The cattle have a very large impact on helping the grasslands survive, being negative or positive effects. Some of the effects that they have on the lands are giving nutrients to the soil and keeping the Soil Organic Carbon (SOC) stable in the ground.

A Simple, Scalable Method for Reducing Stress in Chicks During the First Seven Days Post Hatch

Newly hatched chicks will, among other responses, trample each other in their enclosures due to sound-induced stress, such as low flying planes or doors closing loudly. The objective of this project is to test if white noise or classical music can reduce stress in chicks, specifically in the first 30 days from hatch, due to masking noise stressors or by acclimating the chicks to sounds around them.

A Comparison of Natural Corrosion Inhibitors on Metals

Traditionally, corrosion inhibitors have been non-botanical, usually toxic, with some containing heavy metals and not environmentally friendly. This project compares three natural corrosion inhibitors (dandelion leaves, sweet potato skin, ginger root) on mild steel and galvanized steel utilizing two corrosive substances (acetic acid, saltwater).

Hydroponic Planting on Mars

Sanofi Biogenius Canada Award Recipient

This project looks at whether hydroponic planting could be the solution to fresh plants and food on Mars. The project started with the question "can plants be grown using soil on Mars? Is there a better way of growing things there than that dirt?" To answer this, josh made a mixture of Mars soil and used a hydroponic planter to test which grew various plants faster and healthier depending on the variables.
