Fall. 2022
MSE 2010/2160: Introduction to Materials Science and Engineering/Elements of Materials Science and Engineering
- Both classes share the same lectures, MWF at WEB L104 (attendance: ~150)
- For MSE 2010, 10 lab sessions are included, each requires 3 hours of attendance and a formal lab report
- Textbook: Callister, Fundamentals of Materials Science and Engineering: An Integrated Approach
Chen embraces several educational tools to foster active learning. These tools include a classroom engagement system, reading assignments, in-class clicker questions, online communication forum (e.g., Discord), think-pair-share exercises, and in-class DEMOS!
Demos are fun, engaging, and exciting! Here is the list of demos that Chen did in Fall 2022
- Tin vs copper bars
- Tennis ball stacking (HCP vs. FCC)
- Iron wire (volume expansion from austenite to ferrite )
- Molecular models for polymer isomerism
- Play cards to show chain growth polymerization and how to calculate Mn, Mw, and PDI
- Holding hands to show the step-growth polymerization mechanism.
- Rubber bands in liquid nitrogen (demonstrate Tg)
- Atomic trampoline (amorphous vs. crystalline atomic material)
- Skittles in (hot) water to show the dependency of diffusion on temperatures
- Silly putty (viscoelasticity)
- Frozen banana (fracture mechanics)
- Paper clip to show cold working
