  This is a good site for air quality index information.

  03/02/2021 - Comments: The air quality index (AQI) is measuring certain gas and particles in the air that affect people negatively the higher the concentration in the air. Each person can be affected differently depending on their respiratory system (how well their lungs function). So, if one person has asthma and another person does not, their body may react differently to the same AQI amount. AQ can be measured inside and outside depending on the meter that is used. The one you have looks like it measures particulate matter (PM) less than 2.5 micrometers and 10 micrometers.   This site has a good example of explaining the size with a picture.  https://www.epa.gov/pm-pollution/particulate-matter-pm-basics The AQI is measured in micrograms (one-millionth of a gram) per cubic meter air or µg/m3, which is what your meter is measuring at.  This site has a good table to use pasted below.     https://en.wikipedia.org/wiki/Air_quality_index IndexOzone, Running 8 hourly mean (μg/m3)Nitrogen Dioxide, Hourly mean (μg/m3)Sulphur Dioxide, 15 minute mean (μg/m3)PM2.5 Particles, 24 hour mean (μg/m3)PM10 Particles, 24 hour mean (μg/m3)10–330–670–880–110–16234–6668–13489–17712–2317–33367–100135–200178–26624–3534–504101–120201–267267–35436–4151–585121–140268–334355–44342–4759–666141–160335–400444–53248–5367–757161–187401–467533–71054–5876–838188-213468–534711–88759–6484–919214–240535–600888–106465–7092–10010≥ 241≥ 601≥ 1065≥ 71≥ 101  This is a European chart, but should be similar to ours. But our chart is on this site and has other good information for breaking this down for your students.   https://www.airnow.gov/aqi/aqi-basics Overall the AQI is measured for society's health. We breathe in a lot of things we cannot see with our eyes that can have a negative effect on our ability to breath and can cause harm to us. Radon might be a good example if that is an issue in the area you live.   Let me know if you need anything else.   Information provided by Nikki Becker :)
