The purpose of this assessment probe is to elicit students’ ideas about the nature of science. It is designed to find out if students distinguish scientific theories from the common use of the word theory and if they understand how theories differ from laws. For elementary students, getting into the spirit of science and enjoying science are important and will provide a foundation for the development of ideas related to the history and nature of science. Middle school students begin to deal with the changing nature of scientific knowledge and should be introduced to the scientific meaning of the word theory and become familiar with scientific theories that are appropriately connected to the content they are learning. High school students should be able to distinguish between facts, hypotheses, theories, and laws. Teacher notes, standards, assessment, and references are provided. This book selection also includes the Table of Contents, Dedication, Preface, Introduction, and Index.
