The publication contains descriptive outlines or graphic designs representing how different aspects of science could be taught. All representative "models" follow the same format: general purpose, behavioral objectives, background information, materials, the lesson plan, evaluation, suggested activities, references and resources. The six "models" are: A Self-Motivating Evaluative Technique in Science for the Primary Grades; An Introductory Unit on Living Things for the Primary Grades; A Discovery Approach in Teaching Aerodynamics to the Intermediate Grades; The Game as a Technique for Introducing Science Systems to the Intermediate Grades; An Open-ended Approach for Teaching the Meaning of Science to the Intermediate Grades; and An Integrated Science Lesson for the Intermediate Grades.
