Abstract: This research investigates the impact of a classroomintegrated Science Investigatory Project (SIP) focused on bioplastic production from banana peel starch on the research skills and environmental awareness of Grade 12 STEM students. Conducted over 10 weeks with 45 participants at a public senior high school in Taganito, Philippines, the study employed a mixedmethods approach, utilising pre- and post-assessments, attitude surveys, and reflection journals. Students engaged in structured SIP phases, including proposal writing, experimentation, and presentation, with an emphasis on scientific inquiry and sustainable innovation. Quantitative findings revealed a significant improvement in research skills, with average scores rising from 61.7% in the pre-test to 86.4% in the post-test. Notable gains were observed in experimental design (+42.8%) and conclusion writing (+45.3%). Environmental awareness also increased markedly, with survey responses improving from an average of 3.5 to 4.6 on a 5-point Likert scale. Students showed greater confidence in contributing to environmental solutions and a stronger preference for using sustainable materials. Qualitative data from reflection journals reinforced these findings, with 91% of students expressing enthusiasm for hands-on learning and 87% reporting increased awareness of plastic waste issues. Despite challenges such as limited materials and time constraints, students demonstrated growth in scientific confidence, collaboration, and environmental responsibility. The study concludes that SIPs grounded in real-world ecological issues are effective in enhancing students’ research competencies and 21st-century skills, while also fostering environmental awareness and actionoriented mindsets. The integration of sustainability-focused Service-Learning Initiatives (SIPs) into science curricula is strongly recommended.
