Ok, I know this picture turned out super blurry for some reason, but here is my daughter displaying the craft that she made that shows day and night and the rotation of the earth.
My husband and daughter controlling land rovers on "Mars".
My favorite thing about this place is that it wasn't crowded, unlike the other Chicago attractions we visited, which really surprised me. (We went on a Saturday morning and we weren't there first thing either.) My kids had a chance to play and learn and there were plenty of staff that were excited to teach and assist them. There were rockets for them to launch, small learning crafts, remote control land rovers, short educational videos, interactive models, and scale planetary models that they enjoyed. There were also many science artifacts that my husband and I found interesting. I highly recommend this place.
