Expanding on our popular Lets Explore Science series, this book focuses on light and sound. Every day, waves bring light and sound. A wave is a disturbance that travels through matter or space. Students will learn about electromagnetic and mechanical waves, the properties of waves and sound, pitch, amplitude, and the electromagnetic spectrum, as well as how all these things affect the products we use and even us as humans! This book will allow students to apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
