Hazard Is Not the Whole Risk
Distinguish a hazard indicator from exposure and vulnerability in a fictional scenario.

- 60 minutes
- Worksheet + teacher guidance
What you will learn
A natural hazard is a potentially damaging process. Risk also depends on what is exposed and how vulnerable it is. A screening clue does not provide a real-site safety determination or exact event prediction.
Words to use
- hazard: potentially damaging process
- exposure: people or assets in its reach
- vulnerability: susceptibility to harm
Evidence for this lesson
Fictional cards: A—steep slope with past rockfall evidence near an empty storage area. B—the same stated slope indicator near a frequently occupied classroom. No timing, structural vulnerability, current slope stability or protection details are supplied.
Use the supplied record as written; do not invent missing results.Work through the activity
- 10 min · Separate conceptsRead both scenario cards. Mark the shared hazard indicator, then distinguish people exposed from information about their vulnerability.
- 20 min · Compare evidenceList what differs between A and B. Avoid multiplying arbitrary counts into a fake precise probability or predicting an event date.
- 20 min · Identify missing informationAsk about official current assessments, drainage, ground conditions, structures and warning access. Explain why the simple records cannot determine actual risk.
- 10 min · CommunicateWrite a short screening summary that clearly states what is observed, what is unknown and what expertise would be required for a real assessment.

Grade 8 · Hazard Is Not the Whole Risk
Learning goal: Distinguish a hazard indicator from exposure and vulnerability in a fictional scenario.
Expected responses
- Both are described as near a steep slope with past rockfall evidence.
- A describes an empty storage area; B describes a frequently occupied classroom.
- No exact ranking or probability is justified; vulnerability and current conditions are unknown, though exposure differs.
- Current professional/site-specific hazard assessment, ground and structure information, and applicable official guidance.
Understanding check: False; exposure, vulnerability and event details are missing. An indicator does not establish an event or its consequences.
Watch for this misconception
Past evidence indicates a question to investigate, not the date or certainty of a future event.
Assess the evidence
Look for the observations, calculation or explanation named in the learning goal. Accept accurate drawings and dictated responses. Use the expected responses to discuss reasoning; a correct guess without explanation is a starting point for another conversation.
Adapt and extend
Read prompts aloud, enlarge print or let a partner record the learner’s explanation. Rewrite a sensational headline into an evidence-limited screening statement.
