Books with title Sound and Light

Sound and light are two fundamental aspects of experiencing life. For example, sound waves can be reflected off a surface, like an echo, and light can also be reflected, such as when people see themselves in a mirror. Although sound and light waves travel in slightly different ways, vibration is always the source of the motion. Sound and Light explores both types of waves--from how they are generated to how they interact with the world around them. Understanding the way sound and light interact can answer frequently asked questions, such as why the ocean is blue and why the siren on an ambulance seems to change pitch as it speeds past.

This title contains 40 tried and tested experiments, some classic with up-to-the-minute variations, and some entirely new. Scientific principles are shown in action as well as in photographs of their everyday applications. The experiments are all safe to do, use household materials, are manageable but absorbing, and offer rewarding results. Readers are told how long each experiment lasts, what materials are needed, and what the results mean. Eye-catching illustrations and engaging text make this a perfect book for the budding scientist!

Our world is largely defined by what we see and hear, but our uses for light and sound go far beyond simply seeing a photo or hearing a song. Lasers, concentrated beams of light, are powerful tools used in industry, research, and medicine, as well as in everyday electronics like DVD and CD players. Ultrasound, sound emitted at a high frequency, helps create images of a developing baby, cleans teeth, and much more. Light and Sound teaches how light and sound work, how they are used in our day-to-day lives, and how they can be used to learn about the universe at large.

In Waves of Light and Sound, students will learn about electromagnetic and mechanical waves, the properties of waves and sounds, pitch, amplitude, and much more. Readers will love discovering new information in this chapter book while also reinforcing learned skills with comprehension and extension activities. The Let’s Explore Science series allows readers to dive into the world of fascinating science-related topics while strengthening reading comprehension skills. Each 48-page title features full-color photographs, real-world applications, content vocabulary, and more to effectively engage young learners

Tera knows a secret… Someone is going to die on election day. But that’s not what worries her. She learned it from a dying spark, one of the fairy-like companions people in her world use to communicate, and she found the spark in her father’s office. A radical leader is on the rise, and the old factions are determined to stop him at any cost. If anyone finds out her father’s involved, it might be the end of him. If anyone finds out what she knows, it might be the end of her. The only way to keep her city, her family, and her life from ripping apart is to follow the spark deeper into this deadly game of politics that no one can know she’s playing. Her only advantage is her obscurity. She has no following. No one listens to her or even knows her name. But that’s about to change.
