“…Agenda 21, in its chapter 36, highlights environmental education as a process that seeks to develop a population that is aware and concerned with the environment and its related problems. A population that has knowledge, attitudes, skills, commitments, and motivations to work individually and collectively, seeking solutions to existing problems and preserving those that still resist and deserve more attention [3].…”

The objective of this work was to investigate the treatment of the theme Environmental education in a transversal way with the students of the 1st periods of the courses of Buildings and Integrated Sanitation of the IFPE (Federal Institute of Education, Science and Technology of Pernambuco) -Campus Recife, under the perspective of awareness of these students, with mathematics as an important aid tool. The survey took place in July and August 2020, where questionnaires were applied through Google Forms to 80 students. In a second step, another form was sent to the teaching segment, in a total of 50 questionnaires. The questions addressed in the questionnaires to students led to points such as the perception of the existence of environmental problems, also seeking to analyze the degree of understanding of students in relation to mathematics as a support to environmental education. Subsequently, tabulation, statistical treatment and analysis of the data obtained through descriptive statistics were performed. The results revealed that a significant portion of the students came to understand that the environmental issue is not only a matter of nature, but also of society. Although, it should be noted that some of them can better understand what an environmental problem is than fully understand what the environment is. As for the professors, they demonstrated to relate to the current reality of the planet, however, a portion of this segment suggests that the structure of work to approach the theme is not so adequate.

Resumo: A utilização de modelos matemáticos que descrevem a evolução temporal de populações (crescimento ou decréscimo) pode ser extremamente útil para a escolha de medidas preventivas e/ou de controle. São muitas as ferramentas matemáticas disponíveis, e uma escolha adequada depende tanto do tipo de informações disponíveis quanto dos objetivos almejados. Buscando explorar conteú-dos matemáticos do Ensino Médio, neste trabalho são apresentados alguns modelos matemáticos que descrevem o crescimento da população do Estado de São Paulo, a partir da utilização de diferentes funções. Diferentes taxas de crescimento são exploradas, e as características e hipóteses básicas de cada modelo proposto são apresentadas. Uma comparação quantitativa e qualitativa é feita para validar os modelos obtidos. Palavras-chave: Modelos matemáticos. Dinâmica populacional. Taxas de crescimento.Abstract: The use of mathematical models which describe the evolution of populations through the time (increase or decrease) can be very useful for making choices in preventing or controlling growth. There are so many mathematical tools available and an appropriate choice depends not only on the information but also on the expected goals as well. Aiming to explore mathematical ideas in high school, in this work some models are presented to describe the increase of São Paulo State's population, using different functions. Different growth rates are explored and the basic features and hypotheses of each proposed model are presented. A quantitative and qualitative comparison is made to validate the obtained models.
