This volume conatins science fair projects in astronomy, biology, chemistry, earth science, and physics for young adults ages 12 and up, collected from the "A+ Projects" series, and including some all-new experiments.

Standout science fair projects in five different subject areas With an easy-to-follow introduction to the science-fair process, sample projects in astronomy, biology, chemistry, earth science, and physics, and helpful tips on how to develop original ideas into unique projects, this is the ideal guide for any middle or high school student who wants to create a successful science-fair entry. The book includes all-new projects as well as successful starter projects from previous Janice VanCleave books, offering students choices from all facets of science sunspots, meteors, and plant food to enzymes, the greenhouse effect, and fluid pressure. Creating from A+ Science Fair Projects opens the door to science-fair project success.
