Found the neatest website for learning about space yesterday.
This is the parent page. If you’ll scan down the list, you’ll see boxes that read things like “Help for Cub Scouts!” and “Help for Junior Girl Scouts”. Clicking into one of those, NASA offers a page of resources for not just meeting an Astronomy badge, but all sorts of other badges and achievements, using space-related activities. Need to play a game? Why not a game about space. Need to learn about endangered animals? Learn about how they are tracked from space by satellites.
(I think we need to get someone to collect material for an AHG page!)
By the way, be sure to show your kids the other tabs on the website, too. Plenty of games and activities to keep them engrossed for a long, long time.
