1. The members of Cebu City Environmental Club read an article
about the acidity of
water in lakes and
streams. The authors of the article found that streams are often less
acidic than lakes, Cebu City had several streams and lakes, and the club members were
curious if the acidity of their streams differed from the acidity of their lakes. So, the
members measured the acidity of water samples collected from all the streams and
lakes in the city. The members then made a graph to compare the acidity of the lakes to
that of streams, and they found that the streams were less acidic on average. The
members published a description of their study and the graph in the city's bulletin. They
decide they would repeat the measurements every year to see if water acidity changed
over time.
