Children will love it!.
I recently visited here with toddlers and managed to keep them there for nigh on three hours -- anybody who has toddlers know that's a miracle! The different floors made it exciting and they LOVED "Inside Out" which was the special children's section; they got to pet a snake, lizard, rabbit, and tortoise and couldn't stop talking about the bees! There was an accessible elevator for the stroller, and a lunchroom where you could buy, or bring food to eat. For adults, they have very informative plaques on the animals and explorers.
Taking a closer look at the world around us since 1812.. In Short The Academy of Natural Sciences was founded in the early 19th century; it was decided that the Academy could best serve the public if it split into four parts. There's the Biodiversity Group and the Environmental Research Laboratory concentrates on field research; the Ewell Sale Stewart Library contains a large collection of maps, manuscripts and other natural-science data; and the Museum.
This is the best museum all around. Though not hugh, it has a great collection and a decent gift shop. Exhibits are well structured and you can interact with the staff in the paleo lab. Guides are wonderful with all guests, including groups, couples and kids. They even have an ovenight program where you can sleep with a dinosaur!
