This engaging book describes the properties of sound waves, how they move, and the way our ears catch them. Readers will learn how sound waves travel through different mediums and be amazed by the different ways sound waves are used in real life, such as for communication with animals and deep-sea exploration. A link to interactive activities online plus an activity in the book allow readers to experiment with sound waves to achieve different sounds.
This engaging book describes the properties of light waves, how they move, and the way our eyes receive them. Readers will learn that we see an object when light reflects from its surface and into the eye. A link to interactive activities online plus an activity in the book allow readers to create models that explore how to redirect and block the path a light wave travels.
In this fascinating title, readers explore how light and sound waves transfer information. From telescopes that extend our sense of sight to satellites that help us communicate across large distances, patterns of waves transfer information in many ways. A link to interactive activities online plus an activity in the book allow readers to use what they have learned about waves to engineer wave patterns that communicate across distances.
This exciting title introduces readers to the concept of a wave and the patterns and properties common to both light and sound waves. Clear text and detailed diagrams combine to demonstrate the cause-and-effect relationships involved in the properties of amplitude, wavelength, and frequency. A link to interactive activities online plus an activity in the book allow readers to explore key concepts close up by creating their own wave models.
Sounds help us understand the world around us. This engaging title provides a close-up look at the science behind different sounds. Readers discover how sound waves travel through different matter and learn about concepts such as echoes, volume, and pitch. Accessible language and relatable examples support reader comprehension.
This engaging title introduces readers to the science of light waves. Relatable examples, accessible text, and a creative design challenge help readers discover the properties of light waves and their essential role in seeing our world.
What happens when light is blocked? How can we redirect light? Readers will discover the answers to these questions and more in this fact-filled title. Readers will explore the properties of transparent, translucent, opaque, and reflective materials, and learn how to redirect light beams and create shadows.
