Rube Goldberg machines are comical machines with many parts. This problem focuses on engineering energy transformations to make a functioning Rube Goldberg machine. The function of the machine, the materials used, and the number or type of energy transformations required can be altered to fit your resources and class. All the changes in motion and form in a Rube Goldberg machine require energy transformations or transfers. In this problem, students design a Rube Goldberg machine that performs a simple task in a complex way and includes at least 10 energy transformations. An important part of designing a Rube Goldberg machine is planning the energy transformations. A materials list, teacher background information, safety practices, assessment, and outcomes are provided. This book selection includes the Table of Contents, Preface, Catalog of Problems, Acknowledgments, About the Authors, Image Credits, and Index.
