M 
Introduction (1) 
Explain course administrative policies, e.g.
development and evaluation activities, homework guidelines, etc. 
Discuss place of ES201 in SEC. 
Discuss engineering vs. science, engineering
science vs. science; engineering analysis vs. engineering design. 
Discuss Systems, Accounting, and Modeling
Process. Demonstrate how it's natural to construct a model: select a
system, count something (accounting principle), and make modeling
assumptions. Illustrate usefulness of symbolic solution.

T 
Basic Concepts (1) 
Answer questions about Chap 2. Tough and
abstract chapter that will be revisited many times. Just introduce key
concepts, e.g. use example to introduce SAM Concepts: fundamental laws & accounting
principles: system, properties, process, accounting concept (storage,
transport, and generation), and conservation. 
Review units and dimensions, esp. use in
calculations and unit conversions. 
Explore difference between mass (kg, lbm, slug) and weight (N,lbf):
W=mg.
