Calgary Youth Science Fair Society

Every April (since 1962!), we bring together the vivid imaginations of nearly 1,000 students in Grades 5-12 to showcase their ingenuity by participating in the science fair and wondering how things work.

Asking why, thinking – what if it was better?

And then applying the scientific method to dig for answers. In collaboration with Calgary and area schools, we provide a fun science fair experience where students:

  • Interact with their peers
  • Explore their interests
  • Grow their knowledge
  • Acquire real life skills such as critical thinking and creative problem solving
  • Are acknowledged for thinking, differently
  • Gain greater insights into the world of Science, Technology, Engineering and Math that’s all around them

Through the discovery process, students deepen their realization that they have the ability to make real contributions to improve our world in areas such as:

  • Detoxifying our environment using an innovative sand filter
  • Gaining insights into how human cells function to help improve our health
  • Reducing micro plastics in our waterways
  • Exploring safer travel with a wheel that adapts to changing terrain

The knowledge, friends, mentors and discoveries made along the way become lifelong experiences they’ll always remember and carry with them throughout their careers.

2016 Annual Report Highlights:

  • We hosted over 900 students representing over 700 projects with 550 volunteer judges. With 54 years of history, we host one of the largest science fairs in Canada.
  • With Calgary’s economic uncertainty, we worked above and beyond to meet our benchmark of an exceptional science experience for our students. The Fair remained a high quality, enriching, and overall excellent experience for students, volunteers, and donors.
  • Canada Wide Science Fair 2016 was held in Montreal this year, and twelve finalists from our Fair participated. Team Calgary brought home 4 gold medals, 4 silver medals, 3 bronze medals, 24 scholarships and 6 awards (incl. Best Junior Project), $45,000 award value.

 Amazingly, the Calgary Youth Science Fair is 100% volunteer-run. It’s where curiosity meets the imagination that inspires discovery and drives innovation.

The magical science fair formula is a passion for Science, Technology, Engineering and Math (STEM) combined with:

4 Days in April  +  Nearly 1,000 Grade 5-12 Students  +  Over 700 Science Fair Projects

+  100 Awards  +  Over 500 Medals +  550 Dedicated Judges +  80 Passionate Volunteers

+  Generous Sponsors & Donors  +  $200,000 Annual Fundraising Budget

+  Imagination  +  Ingenuity  +  Innovation

CYSF  +  Amazing Discoveries & Innovations Solving Real World Issues.Since she was 10, Hayley Todesco has been passionate about environmental issues. At the age of 16, Hayley wondered if she could find a way to accelerate the detoxification of the tailings ponds in Alberta. So she spent two years designing and testing the effectiveness of sand filters on the biodegradation of toxic naphthenic acids such as those found in the oilsands.

  • “Application of these inexpensive and sustainable bioreactors could significantly accelerate the detoxification of Canada’s oilsands,” explained Hayley Todesco. Conventional bioreactors would take over 200 years to cleanse the tailings from the naphthenic acids. With her new system using sand filters and a biofilm, it could biodegrade them significantly faster taking only 19 years rather than centuries. Hayley is currently refining her designs and pursuing pilot project opportunities in the oil industry.

Hayley also reached international recognition with her 2014 CYSF science fair project by winning the senior age category and a $25,000 scholarship at the 2014 Google Science Fair beating out her competitors from around the world.

As of September 2016, Hayley is now in her third year studying microbiology at the University of Alberta. Hayley Todesco – CYSF Alum 2007-2014
