From the archives of Scientific American magazine, more than 72 years of experiments and projects from every The Amateur Scientist column ever published. (That's over 850 articles, and roughly 1400 projects.) Each article is complete with all of the original photos, diagrams, and sketches. These are actual construction articles rated by difficulty, cost, target age, and safety. Articles from such well known authors as Albert G. Ingalls, C.L. Stong, Jearl Walker, Shawn Carlson, and others. Widely considered the "science deal of the century" and the "ultimate resource for hands-on science," this is the most complete compendium ever assembled for citizen scientists, home schoolers, STEM educators, science fair students, researchers, schools, colleges, clubs, organizations etc. Covers Astronomy, Archeology, Biology, Botany, Chemistry, Earth Science, Mathematics, Microbiology, Physics, and General Lab Techniques. It includes over 2000 pages of Technical Notes and tons of helpful science secrets that never appeared in Scientific American, covering topics from choosing binoculars for astronomy to monitoring earthquakes at home, as well as Dr Shawn's "A Guide to Science Fair Projects". This is a "must have" for anyone interested in hands-on science.
