Essential Question

How does a snowflake form?


Students will be able to: List the three essential components of a snowflake (air, water, particle) and describe the events that form snowflakes.


A snowflake forms when an extremely cold water droplet freezes onto a speck (pollen, dust, bacteria, etc.) in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the crystal, building new crystals – the six arms of the snowflake.
