Testing Ottawa's downtown core’s snow acidity vs. Ottawa's greenbelt’s snow acidity

We wanted to test to see if the acidity of snow can be increased by car emissions. We decided to collect snow from high traffic areas of Ottawa and low traffic areas of Ottawa and compare them to see if car emissions really do affects the acidity of the snow. Morgan and I collected thirty samples of snow from the high traffic area of Bank Street. Yuchan and Sara collected thirty samples from the low traffic suburban area along the greenbelt. We then tested these samples for acidity and graphed the data to compare it.
