draws attention, perhaps considered one of the biggest challenges, is the migration of people
from the countryside to the city.
The specialists highlighted situations from the past, such as the non-existence of
electricity; the materials used in the construction of the houses; the buses that passed closer to
the houses; the existence of passenger trains, and more unity among neighbors. Also mentioned
were situations related to the change in the number of animals, especially the production of
cattle that was replaced by crops.
In the last question of the interview, about how the water comes to their homes, they
mentioned the existence of a waterhole or artesian well; and pumps for water withdrawal. They
also mentioned the presence of objects used in the current hydraulic installations in their
homes, such as pipes, sleeves, water tanks, and faucets, presenting a simplistic view of how
water reaches their homes.
Although important lines were extracted from the interviews, this stage of the IIR
presented a greater degree of difficulty, considering that the students were not literate. Thus,
they required more help from parents to read the questions (for them to ask the experts) and to
transcribe them on paper. Also, those who chose to record the interviews on audio or video
required parents to film or send audio to the teacher.
Sasseron and Carvalho (2008, p. 138) reiterate that "science teaching should occur
through open and investigative activities in which students play the role of researchers". At this
stage, however, it is not possible to identify the level of student involvement or to propose
further discussions among them. In Kindergarten, the conversation circles are an opportunity
for students to build relationships between scientific knowledge, the technologies associated
with this knowledge, and the consequences for society and the environment. The teacher is
fundamental in this mediation, in the use of appropriate language, and in the identification of
the elements raised by the child. Therefore, we highlight the teacher's essential role in
mediating learning, especially in Early Childhood Education.
Stage 5 sought to promote dialogue between parents and children about the different
animal habitats, and to build a birdhouse with recyclable materials. When planning this step, it
was thought to explore the learning objectives (Brazil, 2017): "Expand interpersonal
relationships, developing attitudes of participation and cooperation" (EI03EO03), and express
themselves freely through drawing, painting, collage, folding, and sculpture, creating two- and
three-dimensional productions (EI03TS02). This case strengthened the relationships among the
