Genetics and Evolution Science Fair Projects (Biology Science Projects Using the Scientific Method)

Why do some humans have curved thumbs while others have straight thumbs? What is DNA? What happens during cell division? Using easy-to-find materials, young scientists will explore genetics, evolution, and classification, and more—all with the help of the scientific method. For students interested in competing in science fairs, the book contains lots of great suggestions and ideas for further experiments.

Gr 5-8–Good starting points for science-fair ideas. Both titles begin with a description of the scientific method and how vital it is to follow it when conducting science research. The books also provide the scientific background necessary to understand the experiments, but Calhoun's information is not as extensive as Gardner's. The process of forming a hypothesis, designing an experiment, recording data, as well as writing and presenting a project are discussed. Calhoun's experiments examine biological diversity, survival needs, and physiological responses and adaptations, Gardner includes entries on classification, evolution, adaptation, and heredity. Experiments include a list of materials required along with the experimental procedure and possible results and conclusions. Highlighted text boxes give further project ideas, and a list of science-supply companies is provided. The uncluttered texts are complemented by illustrations and graphs where necessary. Titles are revised from earlier editions; the introduction is expanded, sources updated, and the layout more appealing. The experiments are not the most exciting and outrageous, but they are doable and cater to a range of abilities. Solid choices.Ragan O'Malley, Saint Ann's School, Brooklyn, NY
