For upper elementary and middle school students, this book is an introduction to cells and microbes.   A dozen different science experiments are detailed in a step-by-step fashion starting with a basic question and then moving from hypothesis through procedure to the result and conclusion.  The introduction addresses topics such as: How Scientists Search for Answers, Using the Scientific Method, designing the experiment, recording data, writing the science fair report and tips for success at the science fair.  Illustrations, charts, graphs and macro-photography aid in understanding.   Table of contents, index, further reading list, internet sites list, and three appendices: microbe identification guide, microscopy and image processing, and science supply companies round out the book.

This will be a heavy read for 5th and 6th grade, but the experiments are easy to accomplish and to understand, making it a good choice for students who want more of a challenge.
