12 weeks of winter: Take a closer look at snowflakes

UNIVERSITY OF MINNESOTA EXTENSION - www.extension.umn.edu

We've all heard that every snowflake is unique, but did you know that they can be categorized into several broad categories? As you can see from this Field Guide to Snowflakes, there are eight shapes that snowflakes can come in, but the two that we think of as having that classic snowflake shape are called dendrites and plates. 

Ready? Let's go searching for snowflakes! Get dressed warmly and head outside during or after a snowfall. See if you can isolate one individual snowflake and identify its crystal type. A dark surface, such as a black mitten or glove will help you to see the individual flakes. Sometimes it helps to pick up a handful of snow and sprinkle it onto a surface to isolate the flakes and get a better view.

Taking photos

If you have a camera with a macro lens, try taking close-up photos of snowflakes. If you don't have a macro lens, we found a few helpful videos that show how you can make one for your smartphone using parts from a laser pointer or a disposable camera.
