This work aims to present an educational product for the teaching of Fluid Mechanics,
at the high school level, based on the significant learning theory of David Paul Ausubel,
developed in the 1960s, considering that students can use their existing knowledge , called
subunits, to help in the teaching-learning process and, thus, enable the understanding of
the laws and applications of Physics that occur around you, in your daily life. The edu-
cational product was developed considering the teaching methodology by investigation,
where a didactic sequence (SD) is proposed as an educational product to be used in a
Teaching Sequence by Research (SEI). Following a qualitative approach, the methodology
was applied in two state schools, assisted by the Modular Teaching Organization System
(SOME). SEI was divided into four phases: Experiments such as investigative demon-
strations, Reading texts to stimulate research, Deepening knowledge and Evaluating the
knowledge acquired and involved all the mechanics of fluids, divided into Hydrostatics
(density, pressure in solids, pressure of liquids , Pascal’s principle and Archimedes’ prin-
ciple) and Hydrodynamics (volumetric flow, continuity equation and Bernoulli equation).
To collect application data, questionnaires, photographs, researcher’s logbooks, activities
developed and reports presented by the students were used. The data were analyzed in
search of significant learning indicators. For analysis and tabulation, the Excel program
was used. The results obtained provide evidence that the proposal facilitates the teaching-
learning process, helping students to understand the topics of fluid mechanics. In addition,
we hope to contribute to a greater didactic-pedagogical instrumentalization of basic ed-
ucation physics teachers, with a view to adding and implementing new practices in the
classroom.
