Smithsonian National Museum of Natural History
Featured Collections
Our educators have curated these collections to let students see how comparing collection specimens can lead to new discoveries. 
Researchers who work at the museum and around the world use the museum's huge collection, which has almost 150 million items, to understand something new about how the Earth formed and how organisms live, interact in their environment, and evolve. They also study how people evolved and the diversity of ways that they have interacted — and continue to interact — with each other and their environment over time.
