In this paper we will present the results of the use of an analemmatic sundial as an important pedagogical method, a tool to aid the teaching-learning process of basic concepts of Physics and Astronomy. The sundials were built in public schools in the North and Northwest region of Rio de Janeiro State, where many activities were conducted with the classes involved in the research. The analemmatic sundial or sundial with human involvement is a ludic didactic way to disseminate basic concepts of Physics since the early grades of elementary school. This sundial is composed of a marking in the form of an ellipse, along which the hours are located, and another marking which indicates the position of the gnomon, and whose shadow is used as the pointer of the sundial. In this case the gnomon is a student who actively participates in the teaching-learning process. The sundial is designed in the schoolyard. The activities are divided between the classroom and the schoolyard. In the schoolyard are performed most activities. The student has the opportunity to observe around changes in the apparent position of the Sun. What complicates the use of this teaching resource is the complex process of construction. To assist in its construction we developed a template, i.e., a model of the analemmatic sundial. The project is achieving satisfactory results, which demonstrates how the analemmatic sundial can help to stimulate the investigative nature of the student.
