The members of the Plainview 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. Plainview County 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
county. The members then made a graph to compare the acidity of the lakes
to that of the 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 county bulletin. They decided they would repeat the measurements every
year to see if water acidity changed over time.
