Criteria Feedback
- The student gives the exploration a clear overall structure with a recognizable progression from context to modelling, comparison, and conclusion.
- The student's sections generally help the reader follow the investigation, and the main purpose stays visible throughout.
- Most of the content stays connected to the topic and supports the modelling task.
- Some key time-frame details do not stay consistent across the exploration.
- The flow is not always seamless because of repeated labels, formatting issues, and sections that feel appended rather than integrated.
- The work contains more repetition and extra material than is needed for a concise investigation.

Moderate
Criteria Feedback
- The student uses appropriate mathematical vocabulary such as regression, derivatives, and fit statistics.
- The student includes several useful representations, including tables, graphs, and calculator output.
- The student's communication is often understandable, especially when they explain the general purpose of the models and compare their behavior.
- Several equations and reported values are written inconsistently, which makes it hard to tell which results are being used.
- Some graphs and outputs are not fully labelled or clearly integrated into the discussion.
- The communication would be stronger if the notation stayed consistent from one section to the next.
