This descriptive survey, employing a quantitative research approach, explores strategies for integrating biology and sustainable development into classroom practices in Senior secondary schools within Ilorin Metropolis, Kwara State. The study specifically targeted 200 biology teachers from various senior secondary schools. The integration of biology with sustainable development is critical for imparting knowledge of environmental conservation, sustainable resource management, and social responsibility—key aspects of the global Sustainable Development Goals (SDGs). Structured questionnaires were used to collect data on current teaching practices, methodologies, and the extent to which sustainable development concepts are incorporated into biology instruction. The survey covered areas such as teacher preparedness, curriculum content, availability of instructional resources, and student involvement in sustainability projects. The data were analyzed using descriptive statistics, providing a quantitative understanding of the existing practices and the challenges biology teachers face in implementing sustainability concepts in their teaching. The results indicated that while a majority of biology teachers understand the importance of integrating sustainable development into their lessons, many lacks the training and instructional materials necessary for full implementation. Additionally, effective strategies such as project-based learning, real-world case studies, and community-based sustainability initiatives were identified as beneficial in enhancing students’ understanding of sustainability. However, challenges such as inadequate infrastructure, insufficient professional development, and limited funding emerged as major barriers. The study concludes that addressing these challenges through improved teacher training, curriculum development, and increased resource allocation is crucial for the successful integration of biology and sustainable development in public secondary schools. The recommendations emphasize investing in teacher capacity building and fostering partnerships with environmental organizations to support sustainability education.
