For parents and non-parent students alike, the Denver Nature and Science Museum is a great idea if you’re looking for hours of engaging and fully interactive fun. My favorite section is the Expedition Health area. In this section of the museum you can run actual experiments, test your physical endurance, and see what you’ll look like when you’re 70 years old. I spent about 2 hours in this one area with my daughter and wife. I’ve visited several science museums in different cities and the one in Denver is by the most educational and entertaining (for kids of all ages).
