Our snow is dried out and crusty so we can't make snow angels or a snowman. That won't stop us from having fun outside though!
colored ice cubes activity on Parents.com-- 20 Games to Play in the Snow. My kids ask often to have a colored ice cube scavenger hunt. I keep the colored ice in a bag in the freezer. Salad tongs add more fun and help prevent gloves becoming soaked. If you don't have ice cube trays use small plastic containers. A scavenger hunt for colored ice would be fun in any season!! In the summer it would be a race to find them before they melt!
A home preschool activity in January '08- color the snow. My daughter had a lot of fun! All it takes is food coloring and water in a good spray bottle.
