Janice VanCleave's Energy for Every Kid

How do plants make their own food? Why do the different strings on a guitar have different sounds? What does the color of a star tell you about how hot the star is? What's the difference between gamma rays, X-rays, and microwaves? Now you can discover the answers to these and many other fascinating questions about energy for yourself with this fun-filled science resource. Packed with illustrations, "Janice VanCleave's Energy for Every Kid" presents entertaining, challenging experiments and activities to help you understand the different types of energy - including heat, sound, electricity, and light - and how they bring about change in the world around you. You'll develop your problem-solving skills as you create a 'leaping frog' that turns potential energy into kinetic energy, model sound waves with a Slinky, use a balloon to demonstrate static electricity, make 'sun' tea with solar energy, and much more! Each of the activities is broken down into its purpose, a list of materials, step-by-step instructions, expected results, and an easy-to-understand explanation. Plus, all projects have been pretested so you can perform them safely and inexpensively in the classroom, at a science fair, or at home! Also available in the "Science for Every Kid" series: "Astronomy"; "Biology"; "Chemistry"; "Constellations"; "Dinosaurs"; "Earth Science"; "Ecology"; "Geography"; "Geometry"; "The Human Body"; "Math"; "Oceans"; and, "Physics".
