In Spacecraft, readers will be introduced to the evolution of spacecraft technology over time, and peek into the possibilities for the spacecraft of tomorrow. This fact- and photo-filled book explains how engineers deal with the challenges of reaching and working in space. The Engineering Wonders series for grades 4–8 explores the ways engineers identify the needs to be met and/or problems to be solved and crated solutions through innovative design. Featuring 48 pages, this series takes a look at a variety of structural, technical, and transportation engineering and their applications

"Hydrogen is the most widespread element and one of the building blocks of life. First appearing when the Big Bang created the universe, hydrogen is now part of human technologies that could change the future. People have used liquid hydrogen to send astronauts into space and hydrogen gas to drive families to the store. In this informative text, we'll explore the first element in the periodic table, looking at its properties and finding its hiding places. From our bodies to the Sun, hydrogen is everywhere!"--

You wouldn’t look for a cow in a tree, or a shark in a forest! Animals live in specific habitats that have the things they need to survive. Different animals eat different kinds of food. They like different weather and fear different predators. In Super Science: Cows Don't Live in Trees!, readers in grades 1-3 will discover some of the many reasons why animals live where they do!This series presents standards-supporting concepts in relatable, often-humorous ways to engage young readers and provide teachers with fun informational texts to support science curriculums. Maximum information is delivered with minimal text to engage and support early readers.

What will the weather do today? In this book, readers in grades 4-9 will learn about ways people have developed to predict the weather, from looking at the sky to running models on a computer. Temperature, pressure, and wind speed are among the factors that determine whether to look out for sunshine or a tornado. Weather prediction not only helps you plan your day, it can even save lives!This series features a variety of science topics aligned to NGSS standards. From mixing matter to the study of sound waves, each informative book includes a glossary, comprehension questions, and an activity for home or the classroom.

Science and human creativity come together in amazing feats of engineering. Today people are landing enormous rockets gently on the ground, helping animals safely cross busy roads and creating cars that drive themselves. How Do They Do That? examines the work done to make incredible machines and structures. Young readers learn how engineers identify problems and use technology to develop solutions.

Energy flows all around you. It warms the air and powers our machines. In this book, readers in grades 4-9 will discover how power from the sun journeys to Earth’s surface and back out to space. The sun’s energy can be reflected, absorbed, used by plants and animals, given off, or trapped to warm the atmosphere. Learn how heat in the atmosphere is rising and what people can do about it. Earth’s energy flow affects every living creature on the planet—including you!This series features a variety of science topics aligned to NGSS standards.
