In this article, the authors discuss the possibilities and benefits of inquiry-based learning at National Park Service (NPS) parks, historic sites, and their companion websites. They also stress that you can extend the guidance and resources that may be provided by any historic monument or park close to your school, whether it is a part of the NPS system or not. The authors provide steps to help you locate a monument or site that you want to study in your classroom, as well as a selection of NPS parks and monuments that they feel provide excellent, inquiry-based K-6 social studies curricula, including virtual tours and virtual ranger visits to classrooms. The article includes ideas for scaffolding to generate excitement and anticipation ahead of the lesson.
