The three original volumes are cherished in the Netherlands by physics teachers and are used as a useful resource for many lectures. We hope that this translated and updated open access book will be just as valuable to a wider range of physics teachers. About this book# This book originated in the collaboration between physics teachers and physics teacher educators, united in the Dutch Association for Science Education(NVON). The three Dutch volumes of ShowdeFysica cover over a 200 demonstrations for secondary school physics, along with additional text on the pedagogy of physics demonstrations. Tip The different chapters on the pedagogy of physics demonstrations provide an excellent start as well!
