<li>Carbon dioxide (CO<sub>2</sub>) is a harmless gas that we exhale. It is useful to measure CO<sub>2</sub> because it tells us about how many people have been breathing in a room and how good the ventilation is. This indicates the risk for transmission of airborne viruses like COVID-19 and the common cold. Read more in the <ahref="http://go.osu.edu/co2">CO2 information Google Slide Deck</a></li>

<li>PM2.5 is a type of particle pollution. PM2.5 means “particulate matter” with diameters less than 2.5 micrometers. Because these particles are so tiny, they can be easily inhaled and may even enter the bloodstream, which can have an impact on health over time. In classrooms, it may come from outdoor pollution like car exhaust as well as from heating systems, chalk, and drywall and cement wear. You can read more about PM2.5 from the <ahref="https://www.epa.gov/pm-pollution/particulate-matter-pm-basics">Environmental Protection Agency</a></li>

<li>Noise can be considered a form of pollution. In the classroom, noise may originate from student chatter, nearby traffic, or loud HVAC systems. Over time, high noise pollution can contribute to “stress related illnesses, high blood pressure … hearing loss, and lost productivity”. High noise levels can interfere with learning as students have trouble hearing the teacher, concentrating, and remembering as discussed in <ahref="https://www.nationalacademies.org/read/11574/chapter/7#45">this report</a>. If an area has high noise levels, it may be possible to reduce the noise levels with acoustic tiles on the walls or ceiling or by adding carpet.</li>

<p>In a spreadsheet make a list of rooms in your building. We are interested in the CO2 levels in each room, the particulate levels measured by PM2.5 (or the Air Quality Index which is derived from the PM2.5), and the sound levels. Maybe we are trying to select a room for a special meeting, or we are just curious about which classrooms are quieter and have better ventilation.</p>
