The unifying theme of our new Permanent Science Galleries is Natural Cycles Shape Our Land. Natural Cycles operate on scales grand and small, from tectonic plates being created and destroyed to tides rising and falling, to animals changing their activity patterns from day to night. Visitors will journey through seven galleries, first encountering vast cycles that unfold over millions of years at global scales and ending their tour with small cycles that unfold at minuscule scales in their own back yards. Galleries focus on our region鈥檚 Geology, Paleontology, Ice Age, Marine Ecosystems, Terrestrial Ecosystems, and finally the Big Back Yard. At the midpoint of their journey, visitors can stop in our Natural Science Lab, a space for visitors to explore hands-on activities, presenters to share experiences, and families to rest, read, and play.
