The investigations are designed to be used by teachers, family child care providers and others who work with and care for young children. There are two series of investigation sample books: * One series is designed for preschool and kindergarten age children and, with minor adjustments, can be appropriate for children in the primary grades. * The second series is designed for infants and toddlers. Each investigation contains a series of engaging, open-ended experiences that inspire curiosity and inquiry as young children investigate important science topics.
