SpeedMeasure Up with Science explains how and why we measure. The series looks at measuring from ancient times to the present day, with ideas on how to make your own measuring instruments. Packed with dozens of hands-on projects, each book will help children experience firsthand the important ways in which measuring enriches our understanding of the world around us. Learn how your heart speeds up when you exercise and what makes other things speed up and slow down. How speed is measured on land, sea, and air gives way to an interesting presentation of the speed of sound and moving pictures. Children will find the simple "flipper" cartoon they can easily make particularly interesting. |
