Books in Spotlight on Earth Science series

Water covers about 70 percent of Earths surface. Most water is located in Earths oceans, but Earths freshwater is found in the lakes, rivers, and streams located around the globe. This title encourages readers to dive deep into Earths freshwater bodies. Readers learn about important science concepts such as the water cycle and how bodies of water form. Age-appropriate text makes complex earth science concepts accessible for young readers. Readers will be delighted by the photographs that accompany this well-researched text.

One of the most beautiful natural phenomena we can see here on Earth is that of solar and lunar eclipses. Through perfect orbital timing, these events can cause the Sun to disappear and darken the sky in the middle of the day or even to create an eerie red glow seemingly by magic. This book strips the magic away to provide the space science behind these incredible events.

The Suns tiny neighbor, Mercury, is the smallest planet in our solar system, has the fastest orbit, and has the largest temperature variation. In this book, readers will learn about Mercurys speedy orbit and rotation, its nearly non-existent atmosphere, how it formed, and what may happen to the planet in the future due to its close proximity to the Sun.

This physical science volume addresses mixtures and solutions and the technology involved with creating and studying them. Readers will learn about the methods that chemistry pioneers used to arrive at an understanding of the nature of mixtures. Readers will learn how to distinguish mixtures from solutions. Historical examples and contemporary examples from the fields of pharmacology and microelectronics will promote interest and understanding. Diagrams and colorful photographs of scientists at work will help make complex scientific concepts easier for elementary readers to understand.

Sound is more than just the things we hear. It's made up of sound waves or vibrations that travel through air, water, and even solid objects. Readers will learn how sounds are created and about the kinds of sound waves, the properties of sound, and the scientific laws of sound. They'll also discover how we produce music and speech and how we hear. Primary sources and full-color photographs aid readers in understanding this complex physics topic.

Everything we can see and touch is matter, even things we can't see and touch is matter. We can tell the difference between the different kinds of matter through each one's properties, such as density, magnetism, and conductivity. Knowing about these properties and matching the right materials with the right jobs is essential for today's scientists, engineers, and inventors. Informative photographs and stimulating sidebars enhance the accessible narrative, allowing readers to connect significant science concepts to their practical applications. From constructing kitchen equipment that won't burn our hands to engineering spacecraft that will protect astronauts, future scientific thinkers will be inspired by this volume.

What happens when you enter a room and flip the light switch? Why does a cell phone battery run down? This book focuses on electricity, electric currents, and electrical technology. Readers will learn where electric currents come from. They'll discover some of the early pioneers in the field of electricity, including AndrÈ-Marie AmpËre and Alessandro Volta. Students will learn how inventors such as Thomas Edison and Nikola Tesla helped bring electricity into homes. Fascinating modern developments in computing and medicine will help readers see that electricity is essential. Colorful photographs and diagrams help make these complex scientific concepts more manageable for elementary readers.
