In this comic, Calvin brings in a single snow flake from outside in for show and tell. What he demonstrates is the uniqueness that the snow flake possesses until it is exposed to the conformity within the modern classroom. He uses the snow flake as a metaphor for a student. The statement that he is trying to make is that school transforms beautiful unique works of art that children are and turns them into just an ordinary drop of water just like every other child.
