It's getting to snow season outside and when you're done playing in it you can come inside and make snowflakes in the warmth of your home.
Barkleyus.com has a very good online snowflake maker. Just click on "Make a Snowflake" and use the scissors to cut the paper. Check as often as you want to see how your flake is coming along.
Once you're done you can save them, print them, email them or just let them go back into the ether. And you don't have to pick up all the itty bitty clippings.
If you have access to Brainpop there's a great video about how snowflakes are formed at http://www.brainpop.com/science/weather/snowflakes/. These two sites together make for an informative and creative exploration of snowflakes. But it's no replacement for getting out there and playing in the real snow!
