A class considers publishing a map of naturally occurring background detector readings around campus, using teacher-supplied data only. Supplied pilot evidence: Two sites gave 22 and 26 counts during separate 1 min intervals; no repeats or instrument comparison were made. An alarming map label could mislead families if normal variation is presented as a demonstrated health hazard. Evaluate the proposal for students, families, teachers and campus staff. Explain the relevant physics, distinguish evidence from an assumption, discuss a benefit and a cost or ethical issue, and make a conditional recommendation with one further evidence requirement. Treat the supplied figures as a fictional classroom case, not as current product or safety guidance.
Task interpretation
What a complete response should do
Organise the response into a logical argument, linking the physics principle to the evidence and conclusion.
Make assumptions explicit, connect several ideas, and test whether the final result is physically reasonable.
