Wehave developed a simple demonstration of thermoplastic polymeric behavior using low-densitypolyethylene bags. The demonstration illustrates strengthening, rate effects

A portion of this activitywas described originally in a 2005 ASEE Conference paper. The activity has been used forseveral years in the laboratory portion of the course and it has been very successful. However,one question that comes to mind is May we compare cast mechanical properties with those ofwrought properties for similar alloys. During lecture, comparisons of wrought and cast propertiesare frequently made, and it is shown that ratio of wrought to cast properties is frequently greaterthan one. To date, the direct comparison has not been done in this course. Using the studentdesigned solid models, it is possible to

teaching approaches for introductory MSE classes.IntroductionIntroductory Materials Science and Engineering (MSE) is a required course for engineeringstudents from fields which include materials, mechanical engineering, electrical engineering,aerospace engineering, and chemical engineering. For students to be successful in the course andas engineers, they must develop an understanding of the basis for a material's macroscaleproperties. This requires an intuitive awareness of a material's structural, nanoscale, andmicroscale features and their influence on macroscopic properties. However, achieving this goalis a significant conceptual challenge that confronts all levels of learners in developing usefulmental models1 that link the concrete

For example, the shape of the liquidus curve on the iron-carbon phasediagram helps explain why cast steels are more expensive to manufacture than cast irons.In this course, students develop graphical skills from lectures, handouts, and assignments. Forexample, students plot their own hardness readings together with an empirically-derived ASTMcurve, then they evaluate how well their data matches the curve. They create phase diagramsfrom alloy data. They create stress-strain diagrams from their own laboratory readings, andcalculate mechanical properties from the results. They learn how to deal with outliers on ahomework assignment. They learn that Excel’s built-in curve-fitting

This ability to abstract and define an idealized problemfrom complex objects in the world or textual descriptions ratchets the engineer's ability to solvethe problem. Sadly, however, students routinely leave this course having learned to "plug andchug" or jump to a mathematical equation without first defining the problem in a diagrammaticform that articulates the underlying principles. This can lead to serious problems in futurecourses as the fundamental approach to engineering problem solving has not been understood orembraced.
