This is a wonderful museum. The dioramas, the IMAX, the Planetarium (recently rebuilt) are all wonderful and entertaining. Check online or call in advance to see what the special exhibit is and to see if there are live animal exhibits on display. The butterfly vivarium is GREAT, you can walk through a room of free-flying butterflies and watch them drink from flowers/pieces of fruit while the docents explain their behavior and life cycle. You can spend an entire afternoon (many, actually) here and not get bored. They also have great events and guest lectures from the top minds in science on weekends/evenings. Check out their site for upcoming events.
Pros: IMAX, Live Exhibits
Cons: Can get crowded
