Cause, Effect, or Coincidence?

Students read a short lab microtext, list every pair of events, apply the counterfactual check (if A had not happened, would B still have happened?) and the mechanism check (does the text state or clearly imply how A leads to B?), and sort each pair into supported cause, possible cause, sequence, or coincidence.

Grammar target

Given two events from a short case text, label the relationship as supported cause, possible cause, sequence, or coincidence — and justify the label with a one-line reason that cites the evidence.

Essential question

Which events in the case are supported causes of each other — and which are only near each other in time?

Objective

Students can classify pairs of events from a short case text as supported cause, possible cause, sequence, or coincidence, and can give a one-line evidence-based reason for each classification.
