A crack of lightning. The blue glow of a phone screen. A blinking firefly. The blazing sun. A cameraโs rapid flash. No matter the source, light travels in waves, and it does so at a speed faster than anything else in the universe. But what is light, anyway, and how do we study it? In this book, readers in grades 4-9 will learn about light waves and lightโs properties and how peopleโand animalsโmanipulate light for their own purposes. This series features a variety of science topics aligned to NGSS standards. From mixing matter to the study of sound waves, each informative book includes a glossary, comprehension questions, and an activity for home or the classroom.
