With an emphasis on how important light is to our planet, this beautifully-illustrated book explains how light affects photosynthesis, how light travels, and light's different properties. Whether it's ultraviolet light that helps bees pollinate flowers or solar panels that use sunlight to heat our homes, students learn about the various ways that both animals and people depend on light.
"What is light and how does it help us to see? What is reflection? How does light form shadows? Find out the answers to these questions and much more"--
Imagine you are inside a dark closet. Everything around you looks black. You can't even see your own hands in front of your face. Why? Your hands are still there, but something important is missing--light! This in-depth look at light includes understanding light sources, incredible facts about our Sun, how light reflects off objects around us, and how our eyes use light to allow us to see. It also features topics such as shadows, making rainbows, and bioluminescence in the animal kingdom. This book is packed with activities including making shadow artworks, testing your own eyes' capabilities, and even designing a reflective safety jacket for a dog's night-time walk.
This book explains the different characteristics of light and includes simple experiments.
From switching on a lamp to seeing the sun rise in the morning, we experience light every day, but what exactly is light? In this title, students will have the opportunity to conduct experiments to help them understand what light is, how it travels, and how we see it. Kids will also investigate concepts such as what causes shadows to form, and how white light is made up of a mixture of different colors. Using everyday items that kids can easily find around the house, students will transform into scientists as they carry out step-by-step experiments to answer interesting questions. Along the way, children will pick up important scientific skills as they investigate light, record their observations, and draw conclusions. Light includes seven experiments with detailed, age-appropriate instructions, surprising facts and background information, a “Conclusions” section to pull all the concepts in the book together, and a glossary of science words. Colorful, dynamic designs and images truly put the FUN into FUN-damental Experiments.
Using everyday language, spatial concepts, visualizations and his renowned "Feynman diagrams," the author clearly and humorously communicates the substance and spirit of QED (quantum electodynamics).
