This article describes the Collectors' Corner Neighborhood Trading Places (CCNTP) program. CCNTP is a collaboration between the Science Museum of Minnesota, the R.H. Stanford Library branch of the Washington County Library, and the Highland Park Library branch of the Saint Paul Public Library. The CCNTP program invites children and visitors of all ages to bring natural objects to the location and share their knowledge about them, earning points which allow them to trade for other items.
