A brand new edition of TIME for Kids Big Book of How offers curious kids even more answers to the questions they can't stop asking. Colourful graphics, spectacular photos and engaging diagrams will help answer questions such as: how does a chameleon change colours? How do you build a tepee? How do diamonds form? How does Wi-Fi work? How do astronauts train for a space mission? How do we get cavities? Big Book ofHow goes beyond answering the questions and engages kids with hands-on activities at the end of each chapter. These projects for fun or school bring to life topics and ideas covered in the text and pictures.
