Your DNA can help us make a healthier world

Contribute to an important study by SickKids researchers. Become one of our 30,000 Junior Scientists participating in this fun and interactive research project on genetics. 

Your genes and the environment around you help to shape your mental and physical health. SickKids researchers want to learn more—and you can help them!

Junior Scientists and their parents answer questions about behaviour (the way you act), physical health and well-being. Kids and teens also play a computer game to give researchers information about cognition (the way you think).

Then, SickKids researchers collect a saliva sample in a small tube from the kids and teens to take a look at their DNA. It’s quick and easy! 

SickKids staff will follow the health and safety requirements outlined by the Hospital for Sick Children. 

Participation Criteria: Participants must be between the ages of 6 and 17. Parent participation is also required. Children and parents must have proficiency in English sufficient to answer questions about behaviour, health and well-being.

Do you have kids 10 and under who also want to contribute to an important study? Check out Research Live!
