Let's Find Out! Physical Science

Everything that takes up space is made out of matter, whether it's a person, air, or a mountain. This volume covers the fundamental concepts students need to understand matter. Fact boxes highlight and further explain vocabulary words, while "Compare and Contrast" and "Think About It" boxes encourage readers to think and explore the ideas further. The lively narrative uses true-to-life examples to explain concepts, while bright color photographs and illustrations reinforce facts and examples. This informative book supports Common Core Science Standards, evaluation of evidence, understanding scientific theories, and connecting and relating knowledge. Readers will understand why matter really matters!

We encounter friction in our lives every day-at home, in school, at work, and at play. Readers are introduced to friction, its characteristics, and how it works in the world around us. Through clear explanations, concrete examples, and attention-grabbing photos, the author shows how this physical force operates and how it can work to both our advantage and disadvantage. Readers will be fascinated to learn the role friction plays in nature, in sports, in transportation, and many other domains.

The basics of measurement are an important part of the science and mathematics curriculum for students and readers. This volume is a simple and straightforward guide to measurements, including a history on how measurements were formed and have been standardized and basics on measuring distance, weight, temperature, volume, time, and more, along with information on the metric and imperial systems. Chapters contain vocabulary words and simple exercises that help to supplement the text and add an interactive, hands-on learning experience for students wanting to learn more.

Answering its own title question, this book takes the mystery out of magnets and magnetism in language that younger readers can readily understand. Common Core Standards in the physical sciences were considered when determining what material should be covered. Polarity, magnetic fields, electromagnetics, the difference between soft and hard magnets, and the ways in which magnets are used in industry, medicine, and everyday life are among the topics covered. Boxed inserts define terminology and challenge readers by posing questions suggested by the narrative. Suggested experiments with magnets cap this delightful volume.

In this engaging text, readers are introduced to basic concepts of energy and where it exists all around them, right down to matter and the atom. Fact boxes bolster vocabulary words, while "Compare and Contras" and "Think About It" boxes stimulate thinking, reading, writing, and discussion. This illuminating volume supports Common Core Science Standards, evaluation of evidence, understanding scientific theories, and connecting and relating knowledge. The lively narrative with real-world examples explains terms and concepts, and full-color photographs and illustrations energize the text.

This stimulating and accessible volume offers readers a fascinating view of a force known as gravity. Readers examine many scientific concepts, including Newton's laws of gravity, mass and gravitational forces, galaxies, satellites, Earth's solar system, centrifugal force, tides, and erosion. Vocabulary boxes provide additional guidance to readers, and the "Compare and Contrast" and "Think About It" sidebars give students opportunities to ponder concepts in fun and creative ways; for example, "Earth has more mass than Mars. If you stepped on a scale on Mars, would you weigh more or less than you do on Earth? Why?"
