Science Fair Entry Moss Filters

290


How do filters affect air quality?

Can we measure reductions of Particulate Matter (PM) using natural materials as filters?


The Hypothesis: “I believe that the moss will absorb the most PM when compared to a wool, silk and industrial filter. To do this experiment I used particulate sensors and directed air over them and through a filter. This meant building filters and designing and building a testing unit.
In order to bring up the levels of PM as the air entered the tube, I lit incense. Data shows what we expect to see: the greatest average difference (or reduction) between the top and bottom sensors was with the moss filter.”

This Grade 8 Candidate has been invited to attend the National 2023 Science Fair competition.

Thank-you to the North West Regional Science Fair Team of Organizers, Donors, Participants, Parents and Visitors. Those kids got a lot of attention, mentorship, inspiration and reward for their work and interest.
