Thursday, July 31, 2025 – Sunday, August 3, 2025 

We’re ready to rock Canada’s largest gem and mineral show with family-friendly science activities. Try your hand at the techniques practiced by geologists to explore the physical properties of minerals. Can you identify the specimen? We’re looking at amazing things found above the ground, too—way, way above the ground! We’ll explore what it means for us now that the Sun is in solar maximum, take a closer look at our closest star and engage in a fun aurora-themed art activity. 

This event is free with event admission.
