Introduce young students to the physics concept of force in this simply written, colorful book. Young readers learn that force is described as any action that changes the location or shape of an object or how fast or slowly it moves, which is called speed. Examples of force are given. Includes a pronunciation guide for scientific terms. 24 full color pages with many engaging illustrations. Reading Level 1-3, Interest Level 2-5.

By becoming familiar with Latin and Greek word roots, students gain a deeper understanding of scientific terms. Physics Connects to Language helps students identify and define Latin and Greek word roots for scientific terms and other words with the same word root. Each chapter contains several activities that aid learning and retention, including "Mix and Match" and "Test Yourself" sections. This workbook can be used with the Focus On Middle School Biology Student Textbook 3rd Edition, the Exploring Science Books 5-8, or as a stand-alone vocabulary building resource.

A magnet is surrounded by a magnetic field, which is the area around a magnet that has magnetic forces. In physics, force is defined as any action that changes the location, shape, or speed of an object. A magnet has two opposite poles created by magnetic forces going in opposite directions. These are called the north pole and the south pole. Earth is a big magnet and is surrounded by a magnetic field with the North Pole at the top of Earth and the South Pole at the bottom. Scientists think the molten metal in Earth's outer core swirls and creates a magnetic field that extends out into space. The magnetosphere is formed when light energy from the Sun hits Earth's magnetic field. The magnetosphere helps keep Earth from getting too much light energy from the Sun.Pronunciation guide. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.

Earth itself is sphere-shaped. Earth's spheres are layers surrounding Earth. The geosphere is the part of Earth we live on. The geosphere includes the rocky crust and the mantle and core below the crust. The hydrosphere is made up of all the water on Earth and includes lakes, streams, oceans, ice, rain, and snow. The biosphere is made up of all the living things on Earth. The atmosphere is made up of all the air that surrounds Earth and contains the air we breathe. Weather occurs in the atmosphere. The magnetosphere is the magnetic field surrounding Earth in space. It protects Earth from getting too much energy from the Sun. Each sphere is important in making it possible for life to exist on Earth. The spheres can be studied separately or together to learn how Earth works.Pronunciation guide. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.
