Learners explore the invention process by learning about inventions throughout history and how inventions fill needs or wants, by improving existing inventions, and by keeping a toy invention journal. They further their understandings of the risks and benefits of inventions by testing toys and comparing the fun rating and the safety rating of each toy. This free selection includes the Table of Contents, Foreword, Preface, sections About the Authors and About the Picture-Perfect Program, and reproducible instructional materials. As a special bonus, Chapter 1 is also included, which discusses the reasons why picture books should be read in science class.
