This is essential reading for all primary science trainee and beginning teachers who want to strengthen their science subject knowledge. Each chapter tackles a major theme of the new national curriculum and breaks it down into key concepts. For each concept there is a detailed audit to help readers identify their current levels of knowledge and understanding along with areas for development. This is followed by concise definitions, key terminology, detailed examples and ?in practice\' ideas to clearly relate theory to classroom practice. Finally, readers are invited to re-check their understanding and assess their level of competence at the end of each section. The text enables teachers to feel secure in their subject knowledge and confident about effectively conveying that information to their pupils through appropriate subject-specific pedagogy.
