Surrounded by snow and ice — with sleet starting to fall — Ellen Lamont had all the teaching tools she could ever want to explain the states of matter to her elementary students this week.
"What happens to our masks when we breathe outside?" Lamont asked her Grade 4/5 immersion students, each one seated in a homemade snow seat in their outdoor classroom, during a natural sciences lesson taught in French.
She told them what they first exhale is a gas that condenses on their face coverings, and if they are outside long enough in the cold, that liquid may freeze and turn into a solid.
