ABSTRACT
This module, one of 13 NYSCATE modules, features the integration of
mathematics, science, and technology (MST) through an emphasis on design in
the context of solutions and dilutions. Groups of students design, construct, and
test a kit for measuring iron concentration that is to be used in Third World
countries. The kit includes directions (standard operating procedure [SOP]),
small-volume measuring devices, limited distilled water, and other materials. The
procedure establishes a maximum percent error for the iron determinations.
