Adler Planetarium!!
I looked online, and found some really great educational activities all over the area! Of course, it's Chicago--I would hope they have a ton!!
We've decided on the Adler Planetarium! We've never been--and it has always sounded wonderful! But the reason we chose this particular destination was for their Shoot For The Moon exhibit. It looks Awesome! I posted the link above so you can take a look at it! If you are in the Chicago area--come and check it out!! There are a ton of things to see and do, as well as getting up close and personal with a space ship!
My boys will go nuts!!
