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 light microscope and glass slides; and (2) a package of pH (acid/base) test strips
and a digital thermometer. But you find no scientists. Match each testing equipment station to the field
of science to which it belongs, and hypothesize what is being tested in each station.
