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.
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.
Help students explore the wonders of science with the mind-stretching activities in this series. Each book includes a number of special features, with fun, easy-to-prepare activities that cover topics from the three main branches of science: physical science, earth science, and life science. Clear, step-by-step instructions foster independent learning; guided questions help develop observation and critical thinking skills; fascinating facts and extension activities enrich learning. In addition, background information and teaching tips are provided in the Activity Guide at the back of the book to help you maximize students' understanding of scientific concepts.

What is light? Where are optics and photonics present in our lives and in nature? What lies behind different optical phenomena? What is an optical instrument? How does the eye resemble an optical instrument? How can we explain human vision? This book, written by a group of young scientists, answers these questions and many more.
Iconoclastic physics professor and artist Andrzej Dragan presents a unique feast of knowledge on special relativity in a straightforward, progressive manner that even a savvy high school student could follow. Encompassing the derivation of Lorentz transformations to Wigner rotations and Thomas precession; from non-inertial accelerated reference frames to event horizons, curved spacetime, and static black holes; and from the Doppler effect to relativistic structure of electromagnetism, Dragan peels back the enigmatic layers of modern physics to enable a deeper understanding of Einstein's groundbreaking theory.Comprehensive and elegantly written, full of insightful apparent paradoxes and riddles, but without any complicated math, Dragan's unique overview takes the reader well beyond the orthodox verses of standard Special Relativity to the bleeding edge of 'new-fangled' superluminal apocrypha and their relation to Quantum Theory. The book is based on a course on Special Relativity and acclaimed by students taught by Dragan who is a leader of a research group on Relativistic Quantum Information theory at the University of Warsaw and the National University of Singapore.Scan the QR code to access the author's collection of Youtube videos that explain the fundamental concepts of physics described in Unusually Special Relativity.
The return of NASA's first manned mission to Mars was supposed to be a momentous day. But when the crew loses touch with ground control before entry, things look bleak. Safe after a treacherous landing, the crew emerges to discover the unthinkable--every man, woman, child, and animal has vanished without a trace. Alone now on their home planet, the crew sets out to discover where everyone has gone--and how to get them back--only to discover they may not be as alone as they thought.
This book is a rather nontechnical, lighthearted summary of creation.
