Here’s a fun project for a rainy summer day with your budding astronomer. Or a fun end-of-summer project for those kids complaining of boredom. The Discovery Science Center Solar System Mobile-Making Kit ($20) looks fantastic. No glue required and it glows in the dark. Suggested for ages 8 and up. I’d love to do Jenna’s room in a solar system theme and accessorize with this. Also a great project to supplement home-school lessons about planets and the solar system.
