Not one snowflake is alike. Snow can be as small as a pinhead. Snow can melt in your hand. Snow is very cold if it is a winter storm. Snow can also be very dangerous, like if we are on the road it's probably very slippery and that is why people have to plow the snow and put salt on the roads.
Snow comes from the sky and it's in clouds.
Snow comes down when moist air is swept up into the sky by an a cold air mass that changes the moisture in the air to crystals. There are many ways you can play in snow. One way is that you can make a snowman or snow fort. A snowman is three heaps of snow put one on top of the other. Then you dress it up with an old hat, mittens, etc.
