Description
Students assess local air quality based on lichen presence/absence growing on trees on their local campus. They write their own hypotheses based on preliminary information then collect data in the field. They use a citizen science app (iNaturalist) to connect with the broader community by uploading images of the lichens that they find. They collect tree dbh and relate this to air quality using class data. Students then construct a scatterplot and use it to test the relationship between tree dbh and air quality. Finally they calcuate a mean and standard deviation to be used to assess overall air quality on their campus.
Notes
adapted Module 2 only, Lichens in YOUR Local Landscape
minor change in lichen sampling grid, printed on a transparency instead of using a ziplock
datasheet adapated for data class was taking
pH was not measured
canopy cover was not measured since this lab was conducted outside prior to leaf flush
only 3 trees were sampled for each student for already identified to species level trees
