Slime: Classroom Demonstration of Property Change Due to Crosslinking

This five-page guide from Edmonds Community College provides instructors with a laboratory activity that demonstrates plastic flow vs. elastic flow behaviors, hydrogen bonding, and viscosity to students using slime in one class period. This "simple polymer demo applies to metals, ceramics, and composites." This activity demonstrates the effect of crosslinking on material properties and the differences between material compositions. The guide includes the following sections: MatEd Core Competencies Covered, Module Objectives and Student Learning Objectives, Module Data, Equipment and Supplies Needed, Curriculum Overview, Module Procedures, and an Evaluation Packet.
