Come and see what's so big about the super small! NanoDays in Ithaca will be held at the Sciencenter on Saturday, March 31, noon-4 pm, and at Duffield Hall at Cornell on Sunday, April 1, noon-4 pm. The Sciencenter plays an important role in making NanoDays happen because it has a lead role in the NSF-sponsored NISENet that brings NanoDays to communities across the US every March. Right here in Ithaca, we develop the educational activities used by hundreds of museums every year. Each spring, visitors to NanoDays in Ithaca get to preview and try out activities that will become part of the national NanoDays events the following year.
