How are sounds produced? Does light travel in a specific path? Are all shadows black? Using easy-to-find materials and the scientific method, you can learn the answers to these questions and more. If you are interested in competing in science fairs, the book contains lots of great suggestions and ideas for further experiments.

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.

Have you ever wondered why dogs can hear things that humans cannot? Why a flame gives off light? Why certain mirrors make you look shorter or taller? Everyday sounds and sights that you may take for granted travel in waves. You can find out more about these waves when you do the fun, simple experiments in this book. Interested in competing in a science fair? You'll get tons of great ideas that will help you create a unique, award-winning science fair entry. Book jacket.

For use in schools and libraries only. Describes how to complete and present a science fair project and offers suggestions for experiments in astronomy, biology, chemistry, math, and engineering.

Offers experiments and activities to explain the properties of light and sound.

"Learn about sound waves, sound and music, the properties of sound and more"--

Sound and light aren’t just sensations picked up by our senses—they’re examples of science at work in the wonderful world around us! Budding scientists will delight in the text’s age-appropriate experiments, which are made easy through step-by-step instructions and photos. Each experiment is accompanied by a question-and-answer feature that answers common questions encountered while experimenting, and a concluding quiz tests reader’s knowledge of these important science concepts.
