Winter~Snowflake Watching : Student - For Fun
You can actually identify types of snowflakes on a snowy day. A magnifying glass will help, but children, with the ability to focus up close, can even see snowflakes shapes with the naked eye.
Let snowflakes fall on black construction paper or even your sleeve.
Print (PDF) the ONLINE GUIDE to Snow Crystals and take it outside.
"If the crystals look interesting, have some contests to see who can find the different crystal types, who can find the largest stellar crystals, etc. Remember, however -- many snowfalls bring nothing but small, grainy snowflakes that look essentially like white sand. On such days, there isn't much worth looking at. If it's snowing, take a quick glance at the crystals on your sleeve. If they look nice, then grab the kids and go outside to give everyone a look!"1
