What defines a community? What are the roles people have in a community? These are just some of the questions Chapin School Princeton second graders explored in their study of three types of communities: rural, suburban, and urban. Working in collaborative groups to plan what should be in a community, students planned, designed, and built their community models using recyclable materials. This hands-on-learning truly helps them understand how STEM is used across multiple aspects of daily life. When the models were built, students wrote a script for a day in the life of their community and, in the ultimate step, program a DASH robot to navigate the model replica of their community. As students at the best private school in the Princeton area, Chapin students use hands-on learning, STEM, and collaborative work to better understand the larger global community. They are ready to charge ahead into an ever-changing future.
