This interesting book shows how hydroelectricity—a “clean” form of energy generated by falling water—is being expanded to help us build a more sustainable future. Discover how other forms of water-based energy, such as energy from ocean waves and tides, are being harnessed to help create electricity.

Read all about plants and then turn to the Figured Out pages to discover more facts and easy-to-read statistics that bring the fascinating world of plants to life.

Let's figure out Earth and its life cycles through fascinating facts and figures Find out what life cycles are, why every organism has a life cycle, and learn about some of the most awe-inspiring creatures on Earth. Read all about life cycles and then turn to the Figured Out pages to discover more facts and easy-to-read statistics that bring the fascinating world of animal and plant life cycles to life.

More people live on the planet than ever in its history—and they all need energy. One of the ways in which we can meet this increasing demand for energy is through nuclear power. Nuclear power stations do not drain our planet of its resources and can supply a seemingly limitless source of energy. Discover more about nuclear energy, how it is created and harnessed, and the controversies and challenges that surround it.

We are so used to Earth and its wonders that sometimes it is hard to remember that it is just one of the millions of planets scattered throughout the universe. In this heavily illustrated volume, students will learn all about our home planet and its moon. Packed with facts about the planet's properties, students will learn how Earth and the moon work together, what we have learned about the moon from years of space exploration, and the moon's influence on weather and ocean tides. One day they might even live in a colony on the moon

Earth has a limited supply of fossil fuels, and in the near future this supply will come to an end. However, more people live on the planet than ever in its history - and they all need energy. One of the ways in which we can meet this increasing demand for energy is through nuclear power. Nuclear power stations do not drain our planet of its resources, and they can supply a seemingly limitless source of energy. Discover more about nuclear energy, how it is created and harnessed, and the controversies and challenges that surround it.

In this visually spectacular tour of the outer reaches of our solar system, readers discover many intriguing facts. For example, the outer planets are separated from the inner planets by the asteroid belt. And, in addition to discovering Jupiter's moons, Galileo, in the early 17th century, observed the phases of Venus and made careful studies of sunspots. Readers also learn why humans could never live on one of the gas planets. The physical and chemical features and movement of the outer planets and their moons are detailed. Sidebars pique readers' interest in space missions, spacecraft, and space-related data and terminology.

Rachel Carson loved nature since childhood. It was only natural for her to become one of the first conservation advocates and environmental scientists in the United States. Through detailed biography, the main content introduces readers to Carson as well as her work, including Silent Spring and its incredible influence on the United States and the pesticide industry. Sidebars complement understandable scientific content by adding interesting and illuminating information about each topic. Full-color photographs of Carson and accounts of work in the field encourage readers to care for the world around them--even if it's not popular to do so.

Questioning established knowledge isn't usually a popular course of action. Galileo learned this throughout his life as he tested scientific theories using mathematical calculations. He challenged the Catholic Church and Aristotle, which got him into trouble, but also added him to the pantheon of great scientists. Readers learn all about Galileo's most important discoveries through the story of his life, complete with historical images. Sidebars add detail and understandable explanations to the main content, including concepts such as the scientific method and the planets orbiting the sun.

This visually stunning guide gives an up-close look at some of the more elusive objects in space. Definitions of better-known objects, such as comets, as well as lesser-known objects, such as centaurs and trojans, give a basic understanding of space objects and the history of how they were discovered. It also covers the scientists who theorized about their existence and the later scientists who actually discovered them. Readers will also get a look at how these objects can impact our future life and the plans scientists have for how we might learn more about them.

Stargazers have observed Mercury, Venus, and Mars--the other small, rocky planets in our solar system besides Earth--for thousands of years. More recently, we have begun to explore our neighbors in outer space via flyby spacecraft, probes, and rovers. Readers will learn how these expeditions have expanded our knowledge of these planets' atmospheres, surfaces, features, and even potential for life. A must-read for anyone interested in discovering more about space exploration's past, present, and future.
