The analysis of water in a lake or stream depends upon more than one field of science or body of knowledge. Suppose you stumble across a portable water-testing
lab on a riverbank, and you find two testing stations: (1) a package of pH (acid/base)
test strips and a digital thermometer, and (2) a light microscope and glass slides. But
you find no scientists. Match each teşting equipment station to the field of science to
which it belongs, and hypothesize what is being tested in each station.
