Giving primary teachers the background knowledge they need to plan effective programs of work and answer children's questions with confidence, the Third Edition of this popular text now also includes a CD containing 200 science investigations, allowing teachers to explore the topics covered in the book with their pupils. The book relates explanations of scientific theories and concepts with children's everyday experiences, helping teachers and trainees to think about how to present the topics, and includes lots of practical activities. It is also closely linked to the National Curriculum, with new Quick Guides on the CD clearly showing which sections of the book cover each part of each attainment target at Key Stages 1 and 2.
