Book excerpt: The foundation for science, technology, engineering, and mathematics (STEM) education begins in the early years. This book provides more than ninety activities and learning center ideas that seamlessly integrate STEM throughout early childhood classrooms. These hands-on STEM experiences enhance cooking, art, and music activities, block play and sensory table exploration, and field trips and outdoor time. Information on assessment and early learning standards is also provided. Sally Moomaw, EdD, has spent much of her career researching and teaching STEM education. She is an assistant professor at the University of Cincinnati and the author of several early education books.
