Discover the Let's Talk Science Challenge - a free, fully virtual event that encourages creativity and engagement in STEM learning inside and outside the classroom.

The Let’s Talk Science Challenge supports the development of positive attitudes towards science, technology, engineering and mathematics (STEM) for Grade 6-8 students leading to sustained interest in these areas later in their schooling.

At a time when students are on the cusp of making important decisions about their high school course choices, participation in the Let’s Talk Science Challenge gives them a unique, positive experience with STEM. Participation is completely free, so everyone can join!

Don't miss out! Discover the fun of STEM today! 

What is the Let's Talk Science Challenge?

The Let's Talk Science Challenge provides a unique, stimulating and fun way to experience STEM for all participants. 

This competition that takes place in the spring of each year for students in Grade 6-8 across Canada includes a Question and Answer competition and a hands-on engineering challenge. This variety of activities allows students to experience STEM in theory and beyond!

Preparation for the competition is important. Working in teams or individually, students will learn STEM concepts provided in a Study Handbook prior to the competition. There will also be practice quizzes and design and build challenges available weekly so that participants can prepare for the final competition!
