How does a scale work? Why do tightrope walkers carry a pole in their hands? What is a center of gravity? In this lively and informative book, young readers can learn the principles of balance at the same time as they make a letter scale, balancing dolls, a floating sculpture, and a mobile.
The step-by-step instructions are easy to follow, and the materials used are those found around the house or in the nearest hardware store. There are a number of balancing exercises for readers to try. Throughout, the concepts of weight, symmetry, and gravity, are explained by means of simple, straightforward text and clear photographs. With so many toys to make and exercises to try, Balance It! will give hours of pleasure to any young reader.
