Are your students up for a challenge? Let's Talk Science Challenge

Welcome to the Let’s Talk Science Challenge Registration Website!

The Let’s Talk Science Challenge is a team-based, competitive enrichment event for Grades 6-8 students that takes place each spring at over 20 Let’s Talk Science Outreach locations across Canada. Registration opens in the fall but an account can be created any time. Once you are logged in, choose the Let’s Talk Science Challenge you wish to attend and the school your students will be representing.

Creating an account does not guarantee a spot for your teams in the LTS Challenge. You will need to log in and register your teams in order to reserve their spots.

Let’s Talk Science has been making changes and improvements to our web platforms. As we move forward, here are a few tips and tricks to simplify the registration process for some of the programs you know and love.

  •  Did you register for a Let’s Talk Science program prior to October 2019 (Let’s Talk Science Challenge, Outreach, Tomatosphere)? If you answered yes please continue to use your existing username and password. 
  • If you have forgotten your username or password click “Forgot your password” below. You will be asked for your email and a password reset link will be sent to you.
  • First time registering for the Challenge? Please click “Register for an account here”.
    NOTE: In all cases if you have recently created an account on the new Let’s Talk Science homepage, that login information will not work here.

If you are experiencing difficulties, please email Emmanuelle Carty at
