24 Hours of Science: 13th Edition

24 Hours of Science is a full day of activities related to science and technology for audiences of all ages. The event starts on Friday at noon, continues into the evening, and ends at noon on Saturday. The program includes interactive sessions, lab visits, presentations, science competitions, movies, and other special activities. The activities will explore many different scientific fields, including mathematics, health, astronomy, natural sciences, engineering and the environment. There’s something for everyone!

13th edition of 24 Hours of Science: May 11 and 12, 2018




Since 2010, the event has been recognized and supported by UNESCO. In 2010, 24 Hours of Science also received the Prize for the Promotion of Science from the Natural Sciences and Engineering Research Council (NSERC). In 2011, the Association for the Development of Research and Innovation in Quebec (ADRIQ) gave an Innovation Award to 24 Hours of Science in the category of Changing Techno-Science.


It’s YOUR event!



24 Hours of Science is an opportunity for all organizations associated with science and technology. They are invited to offer activities to the public throughout Quebec, either for the general public or for students. Every year the event offers some 300 activities in the 17 regions of the province; between 30,000 and 40,000 people participate.

Quick Engineering Challenge for schools


Once again, 24 Hours of Science offers all Quebec schools the opportunity to participate in the Quick Engineering Challenge. Students are invited to take up this year’s challenge, An Apple Flotation Device, any time between May 1 and May 9, 2017.

Levels: Elementary 3 and Secondary 1 classes (two different challenges).

Objective: Develop a system that will float an apple above the water, without the apple actually touching the water.

The challenge: To achieve this, students will form teams of 2 or 3 people. All teams will have the same equipment at their disposal. But they’ll have to keep an eye on the clock, because there’s a time limit!

To participate: Complete and submit the registration form. Download the documents below to prepare the challenge.

Prize: A natural science kit for the class (the winning class will be selected in a random draw from among the participating classes).
