Children's ✦ Penny’s Take
The Complete Idiot's Guide to Science Fair Projects
Nancy K. O'Leary · 2003
70/100
👍 Worth It
More than 50 project ideas across five science disciplines with graduated difficulty levels — this is a reliable, well-structured companion for students and parents tackling science fairs. O'Leary's chemistry and biology credentials give the content authority, and the Complete Idiot's Guide format keeps things accessible. It is 20-plus years old and some materials or references will feel dated, but the scientific method is timeless and the breadth here is genuinely useful.
