Abstract: Research in environmental education points out the need for an improvement in pre-service teacher education training in this area. This proposal follows PBL methodology and focuses on the development of an environmental education project whose final product is the organization of a science fair for elementary school students. The 5-week project addresses the topic of urban biodiversity decline and uses the butterfly garden as an initiative to mitigate it. Four months after the program ended, a survey was administered to the 86 participating pre-service teachers. A mixed-methods approach was used, collecting quantitative data on perceptions of urban biodiversity decline, the One Health concept, and environmental education, along with qualitative keyword responses to open-ended questions about the butterfly garden’s impact and the project’s value for self-learning and professional development. Participants reported positive perceptions regarding butterfly gardens after participating in our environmental program, recognizing them as both a valuable educational resource and an effective initiative to mitigate urban biodiversity decline. Respondents showed a strong pro-environmental attitude, taking seriously their role in transmitting environmental values. Using a butterfly garden for teaching purposes offers insight into environmental literacy, connection with nature, and improvements in well-being and is a powerful platform for deep and meaningful pedagogical learning.
