Gr 3-5 After three examples of how you can get the wrong answer to a question by not using all the available information, depending too much on other people's answers, or wanting a certain result, Kramer presents the scientific method as a way of getting correct answers more often and explains how to set up an experiment using a control group. He bases his book on situations that children are likely to run into in their daily lives. This is a pleasant book with an open format; an amusing half-tone cartoon on almost every page illustrates the child-oriented experiments and supports the light tone of the book. The book explains the scientific method in greater depth than most encyclopedia articles, and suggests more everyday applications than books (generally for older readers) that are specifically intended to help with science fair projects, such as How Fast Do Your Oysters Grow?
