Sommario/riassunto |
|
"Readers will learn what stars are made of, how shadows form, and why a mirror reflects an image. Radiant photos of natural and electric light reinforce the lessons of each chapter. Suggested experiments are included for children to try at home to help them observe firsthand how light moves, or how they can use shadows to tell the time. Question-and-answer sections and an in-depth glossary wont leave students in the dark on this essential elementary science topic"-- |
