This chapter is a part of a book that recounts the year's work at the Early Childhood Development Center (ECDC) at Texas A & M University-Corpus Christi. Rather than an "elitist" laboratory school for the children of university faculty, the dual-language ECDC is a collaboration between the Corpus Christi Independent School District and the university, with an enrollment representative of Corpus Christi's population. The chapter describes a curriculum model tested during a summer "discovery camp" for 3- and 4-year-olds at the ECDC. The chapter aims to illustrate key components of a developmentally appropriate and need- satisfying early childhood science curriculum model. The chapter discusses the curriculum's objectives, content, scope and sequence, and assessment. The chapter also describes evaluation of the curriculum, which revealed that the children benefitted from the opportunity to explore the natural world, and that teachers developed a greater awareness of the benefits of an inquiry-based science program.
