SCIENTIFIC MODEL / WORKED EXAMPLE
A prediction can be checked
The model is made explicit before the outcome is measured.

MODEL FIGURE / Constant velocity is assumed. The prediction is conditional, not a universal law of moving carts.

OBSERVATION TO BE CONSIDERED
A distance of 6 m is predicted after 3 s. These points are calculated from the rule; no measurements are shown.

QUESTION TO BE CARRIED FORWARD
A test would compare timed positions with the prediction, accounting for measurement uncertainty. Curvature could indicate changing velocity.
