Microbiology is the science responsible for the study of microorganisms, including eukaryotic, prokaryotic and unicellular beings. In the teaching-learning process, the teacher has an important role, seeking attractive methodologies to expose certain content in a way that draws students' attention, relating the students' routine with the exposed content, fixing learning through practical investigative experiment. Thus, this work aimed to present microbiology practices as a teaching-learning strategy at elementary level II. The research was carried out through theoretical and practical classes with the application of a questionnaire before and after the experiments, with students from a municipal school located in the rural-river area of Amazonas. The collection of biological material was performed with the aid of a swab. Biological material was collected from the mouth, feet, hands of students and from the surface of school chairs. At the end of the collection, the material was inoculated in different petri dishes. At the end, the plates were sealed and incubated at 28 ºC, being observed after eight days. After the growth time, it was possible to observe the growth of fungi and bacteria in all plates. With the accomplishment of this research, the students were able to verify that there are microscopic beings in different environments that live in a harmonious way with us every day. In addition, it was possible to complement the contents transmitted in the classroom through practical classes. Based on the evaluation of the questionnaires after the practical class, the students concluded that, in most cases, microorganisms are beneficial to humans.
