Recently we visited the Fernbank Science Center, which is not the same as the Fernbank Natural History Museum. It is much (and I mean MUCH) smaller and (as my kids pointed out) has no children's play area. Still, they have a planetarium and this was a GCA field trip with our online school, so we went.
The kids loved the planetarium. We saw a movie about planets, the sun, stars, the constellations, and asteroids. Very cool. Catherine literally recognized (audibly) every planet before the narrator said the name. About ten minutes into the movie, Sabrina turned to me and, at typical "Sabrina volume," announced "This is so cool, Mommy! They put the movie on the ceiling! Can you believe it?"
Here are the girls in front of the splash-down capsule:
