"This ... title introduces readers to the concept of a wave and the patterns and properties common to both light and sound waves. Clear text and detailed diagrams combine to demonstrate the cause-and-effect relationships involved in the properties of amplitude, wavelength, and frequency. A link to interactive activities online plus an activity in the book allow readers to explore key concepts close up by creating their own wave models."--.

Examines the science of force and movement and how it applies to everyday life.

An introduction to waves and wave motion, explaining electromagnetic waves and mechanical waves, the behaviors of waves, and real-world uses of waves.

A comprehensive guide to physics that covers algebra-based mechanics and practical physics; and discusses units and measurements, scientific notation, vectors, equations of motion, trajectories, forces, torque, circular motion, gravitation, oscillations, and other related topics.

"When disaster strikes and chef Bryce Weatherford is given guardianship of her three young nieces, her life goes from cooking with fire . . . to controlling a dumpster fire. . . . With all this chaos, Bryce jettisons hope for a life outside of managing her family and her new job. It's been years since Ryker Matthews had his below the knee amputation, yet the phantom pain for his lost limb and Marine career haunts him. . . . He knows he's lucky to be alive. Yet, 'lucky' feels more like 'cursed' to his lonely heart. When Ryker literally sweeps Bryce off her feet in the grocery store's baby aisle, they both feel sparks. But falling in love would be one more curveball neither is ready to deal with . . . or is it exactly the change of plans they need?"--Provided by publisher.

A guide to what it takes to be aircraft mechanics.

Forces--those that push and pull on objects--are a critical concept in the elementary science classroom. For learners to truly understand this physics topic, they need to see forces in action. This well-designed book takes an up-close look at forces, exploring essential themes such as gravity, magnetism, and friction, through at-level and engaging text that leads into a related high-interest activity, such as making balloon rockets and hovercrafts as well as testing whether objects sink or float. Colorful images accompany both the main information and the step-by-step instructions.

"Thanks to the Sage's medicine, Mia has recovered, but now she also knows she's in danger of burning out her magic if she doesn't learn how to control it.

But what could a wizard be doing here? They hear of a fortune-teller and realize there's no better vocation for someone with magical powers. Yet even after they spend hours in line, this seer refuses to see them! What does he know that he's not sharing?"--Back cover.

"Deep in the forest, Theo has finally found the mysterious Doctor, whose medicine might save Mia's life. In exchange, Theo must find what the Doctor desires most and bring it back to him. Theo agrees without thinking, but how will he even figure out this riddle, not to mention find what the Doctor's looking for in this vast, forbidding wood full of fairies and monsters? The clock is ticking as Mia lies in her sickbed, and the unknown enemies who attacked her plot their next move"--Back cover.
