Did you know that if you toss boiling water into -22°C air you can make “snow”? MOSAiC students played around with this on board. Boiling water readily emits water vapour, whereas cold, dense -22°C air has a very limited capacity to hold water vapour. Therefore, when you throw the boiling water up, there’s more water vapour than what the air can hold and the vapour condenses out by clinging to tiny particles in the air, like sodium or calcium, and forms crystals. This is similar to how snowflakes are formed.

Students tested out several experiments to develop classroom resources based on Arctic science and the MOSAiC expedition. To access some of these classroom activities click here: https://mosaic.colorado.edu/activities
