Rationale

• Important to All Science Disciplines• Difficult for Students to Understand

and Appreciate• Lends Itself to Modeling and

Simulations• Incorporates and Reinforces Math at

a Variety of Levels• Flexible – Can Spiral Through Levels

Intended Topics

• Energy and Momentum in Classical Mechanics

• Matter and Energy in Food Webs• Matter and Energy in Atmospheric Chemistry

Examples from this Week

Next two slides show similar output for projectile motion using Excel & Stella.

Key teaching questions include

whether either model is student or teacher created and which one is conceptually easier to build, understand, and use.
