I. Introduction

Plastic materials have become irreplaceable and are used as adhesives, textiles, packaging, foams, elastomers, biomedical devices, optic elements, and composites. Such potential applications of plastics are so limitless that there is an exciting future in the plastics industry. Plastics technology is a multidisciplinary subject dealing with materials and properties, testing and characterization, production and process control, parts and mold design, assembly and finishing, process automation and simulation, prototyping, and quality control.

Since the versatility of materials with respect to shaping allows such a wide range of science and techniques to be employed. This results in complex problems for technologists, particularly concerning plastics processing interactions. The complex problems reflect a unique field on a new relationship of the structure-property-process in plastics. In this context, the new experience of technology must be accumulated for students to adopt a “practice-in-theory” in materials engineering courses in engineering technology programs.

“Mechanical Engineering Technology Laboratory II” is a materials laboratory course to provide basic principles in plastics testing for junior students in the Mechanical Engineering Program at Rochester Institute of Technology. The primary goal of this course is to introduce not only theories in plastic materials, but also to provide hands-on-experience in ASTM (the American Society for Testing and Materials) standard plastics testing. There is a general agreement that student’s experience is essential in teaching, since experience-based learning can accelerate students’ abilities to perform creativity, problem solving skills, and team cooperation in the field
