Knowledge about the microscopic universe permeates the reality of all social classes and professions, as it involves basic citizenship issues such as hygiene, environment, food production, disease prevention and cure, and biotechnology. Thus, it is necessary to develop strategies and methodologies that help the teacher succeed in building knowledge about the microscopic universe in general with his students. The use of compound optical microscopes in high school classes encounters obstacles such as equipment value and maintenance, the need for glass slides and complex staining processes. The present work evaluated the use of handcrafted microscopes as a didactic tool for teaching contents related to the microscopic universe, as an alternative to traditional equipment. From this evaluation, two products were generated: a new artisanal microscope model, and a didactic manual that details the construction of four artisanal microscope models and proposes new possibilities for the use of these tools. The manual also includes a selection of samples and coloring methods that can be used in the classroom, as well as suggestions for application within the High School content, based on the Rio de Janeiro State Basic Curriculum and the new National Base. Common Curriculum recently approved. The validation of the products was made from a workshop aimed at undergraduate and graduate students in biology, as well as teachers from public and private schools. From the use of the manual, the participants were able to make and test the models with the suggested samples and the proposed staining methods, having subsequently positively evaluated both the new microscope model and the didactic manual by means of a questionnaire. Therefore, we believe that this work can contribute to the popularization of science, the development of meaningful learning through practical classes and an investigative approach.
