When you take your child outside to look up at the night sky, what does he see? If you live far away from a city, he may be gazing at thousands of stars twinkling above him. If not, he may have trouble viewing groupings of stars from the surrounding "light pollution." Either way, you can introduce your child to the concept of constellations, or commonly known groups of stars, from the comfort of your very own home. Pick a few constellations to serve as the inspiration for a set of placemats crafted by your child!
