A natural-history collection can make a good visit out of a simple comparison. At the Wagner Free Institute of Science, differences between a mineral, a fossil and a skeleton can lead to questions about how people observe, classify and learn from the natural world.

The museum is at 1700 West Montgomery Avenue. Its visitor page lists Tuesday–Friday hours of 9:30 a.m.–4:30 p.m. and selected first-Saturday openings from noon–4 p.m. Check the current calendar for holiday, program and weather closures. Advance registration is preferred to speed entry, but walk-ins are welcome.

The exhibit hall is self-guided, with scavenger hunts available for visitors who want some direction and staff available for questions. The museum occupies the second floor of a National Historic Landmark building and requires climbing a flight of stairs. Contact the institute about accessibility before planning a visit around the hall.

Choose a small group of objects and look for both similarities and differences before reading every label. What detail would help you distinguish two specimens, and what would you need an expert to explain? A museum visit can be valuable without memorizing names: noticing the question that an object raises is a useful beginning.
