This Laboratory Guide contains a set of scripts of experiments used in the
disciplines FIS122 and FIS126 of IFUFBa. Aspects of oscillations, waves are addressed
mechanical and sound, fluids and heat. In addition, the first script provides an introduction to
method of least squares and (one more) presentation to the use of mono-log and log-.log.
The scripts contain a brief introduction to the theme of the experiment where the ideas and concepts basics are presented and discussed. In some cases we write the mathematical relations
among the quantities involved. Next comes the list of the material used and the description of the
experimental procedure that should be adopted by students. Possible modifications will be
announced by the teacher. Finally, the treatment of experimental data that it should be included in the report.
