A young girl and her cat watch a firefly glow, make shadows in the sun and learn all about how light works in this accessible, kid-friendly introduction to the science of light. Where does light come from? How does it work? What is it made of? Join a young girl and her cat on a journey of scientific discovery to find the answers to these questions and more. Over the course of a summer vacation, the pair investigate the many fascinating aspects of light, including natural and artificial light; the many uses of light; how light can be absorbed, reflected and refracted; the meaning of opaque, translucent and transparent; how the eye sees light; and why some animals need less light to see than humans. From forest fires to traffic lights, this book also provides loads of examples of sources of light. Beginning near the shore of a lake looking up at the stars on a summer night, and ending at the same shore enjoying a fireworks display, our guides offer readers an intriguing and lyrical introduction to light and all its mysteries. The second book in the delightfully informative Science of How series, award-winning author Susan Hughes's engaging narrative gives young children an age-appropriate overview of the science of light. Ellen Rooney's friendly and inviting illustrations with their many shades of blue beckon readers to be a part of the characters' fun summertime exploration.
