Internal Energy Alternative Assessment

1. Asks a particular Big Question about a natural phenomenon
   1. This phenomenon has at least two objects/substances interacting OR requires an additional aspect of modeling ( calorie conversion in the "Eating a 0 Calorie Shave Ice" example below.
2. Uses the representations (graphical and algebraic) from the particular unit to create a model of the natural phenomenon
3. Includesreasoningannotations throughout, justifying choices/decisions
4. Uses the model to come up with an answer to the Big Question
5. Uses the CER framework to present the answer to the Big Question
