  The study of viscosity, in the area of fluid physics at a university level,
is of great importance because of the various applications that are presented
in the different fields of engineering. In this work an experimental method of
implementation and validation is exposed, to be able to calculate the viscosity
of some newtonian and non-newtonian fluids, in which the method of a sphere
that descends through a fluid has been used, making Using a viscometer of our
own construction, with the help of the CassyLab sensor and software of Leybold
Didactics, we show the results obtained by our measuring instrument, which is
intended to highlight the versatility and precision of the measuring instrument
prepared by us, in addition In this work the authors want to motivate the
physics laboratory teachers; to explore the use of these tools that allow you
to check the topics seen in the theoretical classes. Finally, we present the
hardworking results of the measurement of viscosity for different fluids, both
newtonian and non-newtonian, for the latter we show the viscosity behavior as a
function of temperature.
