About 6 minutes · 2 reading + 4 practice and checks
Time includes reading, practice, and questions. Extra videos or further study are optional.
See this course’s project requirements

An air-quality interpretation card with pollutant/time metadata, AQI categories, official guidance and revised activity choices for fictional users.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Separate weather, appearance and pollutant information.
  • Compare place, pollutant, time and report type.
  • Classify all supplied category boundaries.
  • Match the particle guide to fictional group/activity facts.
  • Compare indoor alternatives with scope and heat/source limits.
  • Document a changed report and revised decision without personal health data.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Method: applies the course-specific rules to the supplied cases with visible intermediate work.
  • Accuracy: results agree with the stated facts, units, boundaries and independent checks.
  • Reasoning: explains why the result follows and identifies a limitation or unresolved question.
  • Transfer: completes changed cases and revises the final project when a relevant assumption changes.

The idea in everyday life

Fictional alternatives: Room A—facility reports an appropriate cooled activity space and no stated active smoke source; Room B—very hot room with active indoor smoke; no indoor measurements for either. Outdoor particle AQI is 170. The suitability reports are supplied facts, not a learner inspection.

The idea

Outdoor AQI does not certify the air in every indoor room. Outdoor particles can enter buildings, while indoor sources and ventilation also affect conditions. Moving indoors is not automatically a suitable answer if the setting has another problem, such as extreme heat or an active pollution source. Use responsible facility guidance rather than designing repairs or handling hazardous materials.

Distinguish outdoor reports from indoor conditions — worked practice

Outdoor AQI does not certify the air in every indoor room. Outdoor particles can enter buildings, while indoor sources and ventilation also affect conditions. Moving indoors is not automatically a suitable answer if the setting has another problem, such as extreme heat or an active pollution source. Use responsible facility guidance rather than designing repairs or handling hazardous materials.

Fictional alternatives: Room A—facility reports an appropriate cooled activity space and no stated active smoke source; Room B—very hot room with active indoor smoke; no indoor measurements for either. Outdoor particle AQI is 170. The suitability reports are supplied facts, not a learner inspection.

  1. 1. 1. Separate

    List outdoor index and indoor facts separately.

    You should see: Outdoor 170; A cooled suitable-space report; B extreme heat and smoke.

  2. 2. 2. Compare

    Identify the clearly unsuitable stated alternative.

    You should see: B adds known adverse conditions; “indoors”alone does not make it suitable.

  3. 3. 3. Qualify

    Explain A’s information limit.

    You should see: The supplied facility report supports considering A but does not supply a complete indoor pollutant measurement.

  4. 4. 4. Route

    State the real-world information needed.

    You should see: Check responsible facility/local guidance and individual needs; do not inspect combustion equipment or unknown materials.

Now change one thing

A statement says outdoor AQI 40 proves every indoor room safe. Enter supported or unsupported.

Your work

What to finish

An indoor/outdoor scope card with an unsuitable alternative and remaining information needs.

Common mistake

Watch for this

The exercise supplies a suitability report but no complete indoor measurement. Preserve that distinction and rely on responsible guidance for actual use.

How can I tell I understand it?

Reject a changed universal indoor-safety claim from a good outdoor index.
