Reading and listening to Michael:

Snowflakes are a form of precipitation like rain or sleet. They are associated with the winter season because it has to be zero degrees celsius for snowflakes to form. What makes snowflakes so beautiful, is that no two are the same. They may look similar, but none are exactly the same. However, all snowflakes have six sides. Snowflakes are always symmetrical. We know a lot about snowflakes because of one man, Wilson A. Bentley. Wilson combined a microscope and a camera to take microphotographs of snowflakes. Most of the photos that we have today were taken by Wilson.
