Evaluation of the Use of Low Cost Material in Experimentation in Science Education: A Powerful Pedagogical Resource

The experimentation in the teaching of Chemistry, becomes an essential tool for success in the process of teaching learning, since they stimulate the interest of the students in the classroom, thus raising in the student the critical, curious spirit, the non-acceptance transferred. Faced with the difficulties of performing practical activities due to lack of space or appropriate material, it is necessary for the teacher to seek new methods to promote a teaching with real meaning and good results. The use of practices with alternative materials becomes an excellent tool. The methodology was applied in four moments, applying a questionnaire in the first moment, assembly of a simple distillation apparatus with low cost materials in the second moment, application of another questionnaire in the third moment and test of the in vitro distillate, using a solution Of Silver Nitrate in the fourth moment. In this context, the objective of the research was to investigate whether the use of alternative materials, in practical classes, favors the learning teaching process in the construction of knowledge in the teaching of Chemistry and Sciences. Before the experiment, it was noticed that the students already had a limited knowledge on the subject, after realizing the practice; it was observed improvements in knowledge, thus showing the advantage that is to unite theory and practice. We can conclude that experimentation together with theory is a viable, interactive and efficient way of developing knowledge, since one consolidates the other in its actual realization, and proves the possibility and efficiency of using an experiment with low cost materials.
