精彩书评

Kirkus What makes a bubble? Why does it pop? What makes it round? These and a dozen other questions are clearly explained in a brief, readable text in this "Let's-Read-And-Find-Out" Stage 1 science title. Bradley (Weaver's Daughter, 2000, etc.), a chemist and a mother of two enthusiastic bubble blowers, is right on target with questions and answers. Explaining that the air inside the soapy skin of a bubble doesn't push out more in one place or another, she effectively offers a mini-physics lesson. Moving on to demonstrate other liquids, she explains why some bubbles pop easier than others. Clear color photographs help to demonstrate each idea, using a racially mixed group of boys and girls blowing, popping, and examining big and little bubbles in various liquids. The author concludes with a recipe for making bubble solution and additional experiments with bubbles. Young readers (and their parents) will have a good time learning new science thanks to this playful offering. (Nonfiction. 5-8) Children's Literature What are bubbles made of? Why are they round? Why do they always pop? Investigate the basic science of bubbles with an author who has a degree in chemistry. Vivid photographs and clear, simple text introduce young children to science and help answer questions about one of childhood's greatest joys. Bubbles are simply air trapped inside liquid. They are round because the air inside pushes out evenly against the liquid skin. Bubbles eventually pop because their liquid skin dries out and shrinks, making them unable to hold all the air inside. After learning about bubbles and seeing so many pictures of colorfully captured bubbles, it may be the perfect time to make your own. To do so, follow the bubble solution recipe at the back of the book. You probably have the ingredients in your cupboard. Then you can try some of the experiments that follow. For example, if you make a square shaped wand, will you get square shaped bubbles? All young scientists should give it a try. Part of the "Let's Read-and-Find-out About Science" series. 2001, HarperCollins, $15.95, $15.89, and $4.95. Ages 3 to 6. Reviewer:Barbara Kennedy Fewer Reviews School Library Journal PreS-Gr 1-Bubbles here, bubbles there, bubbles, bubbles, bubbles everywhere-big ones, small ones, single ones, or in a stream. Some float gently, while some pop immediately. No matter what they are made of or how or where they are produced, they are always round, never square. A simple, accurate text that is also fun to read explains these facts. Delightful color photographs of charming children making bubbles and of bubbles floating freely reinforce and extend the text. Children will want to participate themselves to test the data. The book includes a page of experiments and a recipe for making a solution (which may need some adult help to prepare). This is science learning at its best.-Pamela K. Bomboy, Chesterfield County Public Schools, VA Copyright 2001 Cahners Business Information. Kirkus Reviews What makes a bubble? Why does it pop?
