This book of experiments aims to show children that science is present in many activities experienced in daily life, without us being aware of it most of the time. The suggested experiments aim to help the reader to understand and share an interest in science and its effect on the world around us. The experiments are original, fun and surprising and are carried out using everyday materials, objects, situations and environments in order to awaken the reader’s scientific curiosity and imagination. The reader becomes the protagonist of this book and has a privileged position: that of being able to learn and surprise themselves, while at the same time leaving those around them astonished by the results of their experiments. By making sense of what they are learning, this knowledge becomes both more useful and harder to forget.
