How do we heat our homes, light our rooms, and power our cars? With energy! In 2014, the United States relied on fossil fuels for about 67 percent of its power. But as the fossil fuel supply dwindles and climate change becomes an increasingly urgent issue, individuals, businesses, and governments are expanding their sources of renewable energy, including solar, wind, biofuel, hydro, and geothermal. In Renewable Energy: Discover the Fuel of the Future, readers ages 9 to 12 learn about these renewable energy sources and discover how sunshine can be used to power light bulbs and how the earth's natural heat can be used to warm our houses. Young readers weigh the pros and cons of different energy sources and make their own informed opinions about which resources are the best choices for different uses. Renewable energy industries provide a booming field for future scientists and engineers. This book shows kids these future jobs and gets them excited about contributing to a world run on clean energy. Hands-on projects, essential questions, links to online primary sources, and science-minded prompts to think more about energy, the environment, and the repercussions of our choices make this book a key addition to classrooms and libraries.

Once, robots were only found in science fiction books and movies. Today, robots are everywhere! They assemble massive cars and tiny computer chips. They help doctors do delicate surgery. They vacuum our houses and mow our lawns. Robot toys play with us, follow our commands, and respond to our moods. We even send robots to explore the depths of the ocean and the expanse of space. In Robotics, children ages 9 and up learn how robots affect both the future and the present. Hands-on activities make learning both fun and lasting.

Ecclesiastes is a persuasive speech with a rhetoric so unique that it can be easily misunderstood. It speaks powerfully to believers as well as nonbelievers because it addresses the question of the meaning of life in the most satisfying way. The heart of this book is an expositional commentary that interprets Ecclesiastes as authoritative Scripture. It seeks to recover the rhetoric of the speech in terms of its comprehensive message on the meaning of life as well as its compelling force to get the message across. Preceding the expositional commentary is an introduction to Ecclesiastes that presents a new approach to outlining and reading Ecclesiastes as a coherent speech. It also presents an overview of the “forest”—the overall rhetorical flow of the speech from beginning to end. This is to prevent one from getting lost when immersed in the “trees” of the expositional commentary. Following the expositional commentary are two topical studies to give Ecclesiastes the breadth and depth of coverage it deserves. The first is an interdisciplinary exposition on the meaning of life. The second is an interpretive essay to defend exegetically the interpretation of Ecclesiastes as a coherent speech.
