The Rock Discovery Center is a large outdoor area where our young visitors learn about the various rock types that are quarried in the northeastern United States. Recommended especially for children in grades 2-6, the RDC experience is a great introduction to earth science. Each visitor collects six specimens to take home. For each rock type we provide instruction in how to recognize it, where it is obtained, and how it is used in society today. Participants are given a partitioned cardboard box in which to place their samples. In this way, school students and others acquire an "instant rock collection" while having an enjoyable, participatory, and educational experience. The rocks are already broken to sizes that fit in the boxes provided, so no tools are necessary. Participation in the Rock Discovery Center also fulfills many of the requirements for scout badges in geology.
