Just like fingerprints, no two snowflakes are alike...but do you know why? Join Tim and Moby in this BrainPOP movie as they explore the science behind these miniature ice sculptures. First, you’ll see the conditions needed inside a cloud for snowflakes to form. You’ll also learn how the microscopic order of ice molecules translates into snowflakes’ unique patterns! Discover why the flakes in one snowfall may have simple shapes, while those in another have more dramatic structures. Plus, find out why the difference in flake structure is linked to humidity and temperature. Follow a snowflake on its unique journey from a cloud to the ground — just make sure you dress warm!
