Process-oriented, age-appropriate science activities make this guide a must-have in all settings where children are learning and developing. Each section helps teachers and parents in finding science activities for a theme-based curriculum, for spur-of-the-moment activities and for letter- of-the-week plans. Supply lists and a sample family letter encouraging collection of easy-to-acquire items help get the science center up and running. And, the theme-specific index and concept-specific indexes make it easy to plan activities to accompany study units.
