Tell Me How It Works

Most kids have seen a thermometer, but few may be familiar with how one works. Readers of this innovative volume get an up-close look at these useful scientific instruments and learn how analog and digital thermometers work. Age-appropriate text introduces this key STEM-related topic in an accessible way. Colorful photographs engage developing readers and help them understand concepts important to the elementary science curriculum. Eye-catching fact boxes deliver further information in concise, manageable portions.

The Soviet Union made history when it launched Sputnik I, the world's first artificial satellite. Now, more than half a century later, there are about 5,000 satellites in orbit around Earth. These marvels of modern technology perform many important tasks, from reconnaissance and navigation to communications and predicting the weather. Scientists have also sent satellites to orbit moons and other planets of our solar system. This volume examines the technology behind satellites, including how they are launched from Earth and remain in orbit. Key STEM concepts are highlighted through full-color photographs and age-appropriate text. Diagrams and fact boxes provide supporting information.

In recent years, it's become more common to see vast, open areas of countryside and costal areas filled with wind turbines. From the outside, these devices may look fairly simple, but inside, there are many complex parts that help turn the wind's energy into electricity. Readers of this engaging guide will get a look at the inner workings of these powerful machines and learn how wind turbines are capable of producing clean, renewable energy. Accessible text is paired with eye-catching photographs that will keep readers engrossed in this compelling learning experience.

Drones have been in the news a lot over the last few years. From the flying unmanned aircraft used by the military to the quadcopters sold at toy stores and hobby shops, it's difficult to deny that drones are everywhere. This volume examines the science behind modern drone technology and helps young readers understand these complex machines. Full-color photographs and diagrams provide context to STEM concepts. Fact boxes provide additional support to the engaging, age-appropriate narrative.

Since the early 1600s, telescopes have helped us examine the stars. Early telescopes used two glass lenses to focus light. Today, we use mirrors in the same way as glass, but mirrors are lighter and easier to make than lenses. To see dim objects that are far away, these mirrors must be very large. They're much larger than the average hobbyist telescope. With this volume, readers will learn about the components of a telescope and the role each component plays. They will read about different types of telescopes and the objects that each can help them see in great detail.

We can experience electricity in nature in a few ways, including electricity as lightning and as static electricity. Electricity is a type of energy that can build up in one place or move from one place to another. We need electricity to power our homes, businesses, and electronic devices. Without electricity, we'd depend on candles for light and fire for heat. Young readers are introduced to the components of electricity and how we rely on electricity to go about our daily lives. They'll learn about circuits and how electricity moves.
