"Each activity begins with a concise explanation of the concept upon which it focuses and includes a materials list, the procedure, follow-up questions, and extensions. These high-interest investigations use materials that are inexpensive, easily accessible, and familiar to students" (National Science Teacher's Association.org, October 2010)
