Discussion Questions Suggested by Carleton College : []


 * It is impossible to actually validate models. Why is that so?
 * Does this mean we can't use models for prediction?
 * Be explicit about how each model you use relates to the real world
 * What does it incorporate?
 * What does it leave out?
 * Why doesn't it include everything?
 * What are the differences between the output from your model and real data?
 * Why do those differences occur? Are they due to:
 * Errors in the model?
 * Errors or uncertainty in the real-world data?
 * Assumptions in the model?
 * Is this model too simple? If so, what other processes or reservoirs should it include?
 * Would this system be better modeled using a different technique?
