This study aimed to explore junior high school students' understanding of biology concepts through everyday-life phenomena found at home and school. A descriptive qualitative design with an exploratory orientation was employed at SMP Katolik Adisucipto in 2026. The primary participants were two Grade VIIb students and one science/biology teacher selected purposively based on their direct involvement in science learning, willingness to participate, and relevance to the research focus. Data were collected through semi-structured interviews, school-environment observation, documentation, field notes, and student experience-exploration sheets. The data were analyzed through data reduction, thematic coding, data display, triangulation, and conclusion drawing. The findings show that students recognized biology as closely related to eating and drinking habits, handwashing, plant care, small animals, waste, clean water, and the school ecosystem. Students were able to explain several observable phenomena, but still experienced difficulty connecting internal biological processes, especially the digestive system, with daily experiences. The study shows that everyday phenomena can serve as a diagnostic entry point for identifying the depth of students' conceptual understanding and suggests that biology learning should move from concrete experience toward scientific explanation through direct observation, visual representation, simple practices, and guided reflection.
