Investigando a riqueza de plantas e as relações ecológicas em canteiros de uma horta escolar

Abstract

This study aimed to develop and apply an investigative didactic sequence (IDS) that would make Botany and Ecology classes more attractive and enjoyable, sparking students' interest. The IDS was developed in the garden of the from a state public school, located in Belo Horizonte/Minas Gerais, with students from the 1st and 2nd year of High School. The garden has seven beds, but only three were in use, while the others were abandoned. The IDS was developed through the following stages: 1- Visit to the garden; 2- Identification of existing plants in the beds; selection of vegetables to be planted in the other beds and their needs (type of soil; amount of water and nutrients needed for optimal plant growth; time of exposure to light, etc.); 3- Awareness of healthy eating; and 4- Identification of ecological relationships occurring in the garden. The abandoned flowerbeds were revitalized with the planting of vegetables that could be cultivated locally and were later used in the school snack. In addition to the IDS, a digital booklet was produced with images of the planted vegetables, highlighting the nutritional importance of each one. The results indicated a significant increase in students' interest and engagement, demonstrated by active participation in classes and practical activities. The didactic sequence sparked students' curiosity, making the learning of Botany and Ecology more engaging and relevant. Furthermore, students broadened their understanding of the topics involved, began to value healthy eating, and considered the importance of school horticulture for the community. The digital booklet was effective as a complementary resource, highlighting the nutritional benefits of the vegetables. The revitalization of the abandoned flowerbeds also contributed to the sustainable use of school space, promoting interdisciplinary learning and strengthening students' bond with the school.
