What makes the heart beat faster or slower? How do tightrope walkers keep their balance? Why does spinning fast cause dizziness? Explore the mysteries and the workings of the human body through this fascinating collection of ideas, projects, and activities. Have fun while you learn about everything from the body's basic building blocks to how the brain receives messages from other parts of the body. Make a model of a human cell that you can eat for dessert. Make a working model of a human lung from a soda bottle, a balloon, and a garbage bag. Through these and other activities, you'll find out how your lungs supply air to your blood and your heart pumps blood throughout your body; how your body sees, hears, feels, smells, and tastes the world around it; how you lose and regain up to five pounds of skin every year; and much more. Most of the materials you need are already part of you; the rest you will easily find around the house or classroom. Every activity has been "child tested" and can be performed safely and cheaply in the classroom, at a science fair, or at home.

How do plants make their own food? Why do the different strings on a guitar have differentsounds? What does the color of a star tell you about how hot the staris? What's the difference between gamma rays, X-rays, andmicrowaves? Now you can discover the answers to these and many otherfascinating questions about energy for yourself with thisfun-filled science resource. Packed with illustrations, JaniceVanCleave's Energy for Every Kid presents entertaining, challengingexperiments and activities to help you understand the differenttypes of energy--including heat, sound, electricity, and light--andhow they bring about change in the world around you. You'll developyour problem-solving skills as you create a "leaping frog" thatturns potential energy into kinetic energy, model sound waves witha 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 ofmaterials, step-by-step instructions, expected results, and aneasy-to-understand explanation. Plus, all projects have beenpretested so you can perform them safely and inexpensively in theclassroom, at a science fair, or at home!
