The Berkshire Backyard showcases examples of the mammals, birds, amphibians, reptiles, fish and insects of the Berkshires. Learn to identify mammals by their tracks and birds by their calls. Match insects to photographs taken under an electron microscope, and test feathers to see which ones are flightworthy.

The Gallery of Rocks and Minerals displays a wide variety of rocks and minerals from near and far. Compare and contrast igneous, metamorphic, and sedimentary rocks in their natural state, view a beautiful collection of polished stones, and see a real meteorite. Watch minerals fluoresce and use a Geiger Counter to learn about natural radioactivity.

Visiting the World in Miniature is like going on safari. From the Northern Tundra to the Amazon Jungle, this gallery provides a glimpse of the flora and fauna of diverse habitats from around the world, with animals shown in 1/10 scale. This gallery houses one of the largest collections of miniature dioramas created by Louis Paul Jonas Studios in Hudson, NY, which also created the famous series of life-size model dinosaurs for the 1964-65 World's Fair, and produced models for many major museums around the world. Some of the diorama backgrounds were painted by Matthew Kalmenoff, the artist known for his work on dioramas in the American Museum of Natural History in New York City.
