physical sciences

Introduces students in grades five through eight to key concepts in physics, focusing on simple machines, using visuals and experiments to discuss work, forces, levers, the wheel and axle, pulleys, the inclined plane, and compound machines. Includes review segments.

Bill explains fluids as stuff that can bend, squish, flow, move, dodge or mosey out of the way without breaking or separating. He offers the examples of ocean currents and weather patterns.Comedy, interviews with scientists and hands-on experiments.

Investigates the manmade materials that make up our modern world and the rarest materials in the natural world, from a planet five-times as large as Earth made purely of diamond to manmade graphene, the toughest, thinnest, most-flexible material known to man.

Text and photographs look at various topics related to physical sciences.

This book describes the properties of sound and the part it plays in communication, entertainment, navigation, health care, and industry covering such terms as decibels, sonar, ultrasound, amplitude, and more.

Charging a cell phone and going for a run both use energy. Plants create energy using sunlight. People eat food and break it down for energy. In short, energy is everywhere! Readers will learn the basic components of energy, including matter and atoms, as well as the many different kinds of energy that exist in the universe.

Presents information and question and answer sections on the physical sciences, discussing things like the states of matter, what the hardest natural substance is, how magnetism and electricity work, and how sound carries.

After reading about the types of jobs chemists have, students begin experimenting with hands-on activities from award-winning author Robert Gardner.

Antoine Lavoisier is considered to be the father of modern chemistry. Using experiments and careful measurements, he created a system to help chemists understand how matter behaves. He discovered and named oxygen and hydrogen, and helped set up a system to classify these and other elements. Perhaps his most famous discovery is the role oxygen plays in combustion.
