National Museum of Nature and Science
This museum houses everything from fossils to moon rocks. The 30-meter (98-foot) model of a blue whale perched at the entrance is a huge hit with children, but, like any self-respecting science museum, this one also has a few kid-pleasing dinosaurs. Although the museum occasionally outdoes itself with special exhibits, it's pretty conventional, with few hands-on learning experiences, so, if time is short, there's no need to linger here for long. To enter, you'll need to make advance reservations online.
