Light and sound both travel in waves, but sound waves travel significantly slower than light. Theories like this are difficult to grasp in words, but there are easy ways to see them in action. With this book's simple experiments, young scientists will test out how light can bend and how even invisible sounds can make things move, helping them understand how even the most complex theories work. Through step-by-step instructions, young readers will learn the right way to set up their experiments and expand on concepts they already know.
