Grade 4 Up-The experiments presented here range from very basic to fairly complex. Standard projects, such as a lava-flow volcano, a bottled tornado, and a potato polarity indicator are included. Directions for much more complex demonstrations, such as creating and using a cyanometer (to keep track of changes in sky color) or testing hydrodynamic hull designs, illustrate the upper range of material. Experiments also cover a wide range of topics including food science, chemistry, astronomy, and botany. Each one has a list of supplies (generally common household products), detailed directions, expected results, an explanation, and display tips. Safety precautions are mentioned but not highlighted. Precise measurements of the results are not emphasized. Well indexed and accurately illustrated with black-and-white pen-and-ink drawings, this book is a good starting place for finding successful science-fair projects.Kathryn Kosiorek, Cuyahoga County Public Library, Brooklyn, OH
