Beginning

ü   Appropriate collection of models


ü   Correct identification of varying symbolic model parameter

Developing

ü  Appropriate initial observations about how the mathematical models are changing

Accomplished

ü  Correctly record varying data from both models


ü  Correctly identify relationship between varying symbolic model parameters and mathematical model coefficients


ü  Description and presentation of calculations used to identify relationships.

Exemplary

ü  Summation of findings using appropriate science and mathematical terminology

Extensions

ü  General observations and explanations about mathematical model parameters that do not change despite varying symbolic model parameters
