Understanding Physics by Isaac AsimovWhile many of us understand complex theories of criticism or finance, we cannot explain why the lights go on when we flick a switch or how a radio works. In this reader-friendly, unabridged edition of three of his best-selling books, renowned science writer Isaac Asimov demystifies physics, teaching the fundamentals in a manner easily understood by lay people. Including the complete text of Motion, Sound and Heat, Light, Magnetism and Electricity, and The Electron, Proton and Neutron, this volume will guide you through the evolution of physics from its early Greek beginnings up to the modern theories of the creation of time, space and matter. Each volume relates the tale of the human quest through the ages for answers to the fundamental questions of how the universe works. Told in its historical context, this quest for knowledge is a story of high drama and uncommon valor, when men put their very lives on the line for the sake of scientific truth.
3 Volumes in One: Motion, Sound & Heat; Light, Magnetism & Electricity; The Electron, Proton & Neutron.
1993 Barnes & Noble reprint of three Isaac Asimov classics. Originally published in 1966.

Light It Up! (Light, Heat, Electricity, & Magnetism)
Good or Bad! Light can be reflected by a mirror, refracted by a lens, or absorbed by an object. Heat can move from one object to another by conduction. Electrical circuits require a complete loop through which an electrical circuit can pass. NSES, In the rectangle above, you will find the fundamental concepts and principles that underlie this standard.
Electricity in circuits can produce light, heat, sound, and magnetic effects. Electrical Magnets attract and repel each other and certain kinds of materials. ( NSES.

BBC Science B. Physical Science For Grades: K-4 Properties of Objects and Materials Objects have many observable properties, including size, weight, shape, color, temperature, and the ability to react with other substances. Those properties can be measured using tools, such as rulers, balances, and thermometers. Objects are made of one or more materials, such as paper, wood, and metal. Objects can be described by the properties of the materials from which they are made, and those properties can be used to separate or sort a group of objects or materials. Materials can exist in different states—solid, liquid, and gas. Some common materials, such as water, can be changed from one state to another by heating or cooling.
