This study investigates the effect of added sugar on the stability of soap bubbles through a hands-on science activity titled “Magic Bubbles” conducted with third-grade students at SDN 1 Karangrejo. The activity was implemented collaboratively, where students observed, experimented, and drew conclusions together under teacher guidance, without the use of individual worksheets. Using a participatory observation method, the research described students’ engagement, reactions, and learning behavior during the process. Findings revealed that soap bubbles containing added sugar demonstrated greater stability and a longer lifespan compared to those without sugar. Students showed high levels of enthusiasm, curiosity, and active participation throughout the experiment. The activity not only fostered engagement but also enhanced students’ gross motor coordination, observation skills, and early scientific reasoning. Furthermore, it encouraged cooperative learning and communication among peers. The results highlight the effectiveness of simple laboratory-based learning as a medium to introduce scientific inquiry at the elementary level. The “Magic Bubbles” activity aligns with the inquiry-based learning approach in science education, emphasizing direct experience, experimentation, and concept discovery through observation and guided reflection. This study demonstrates that contextual, play-based science activities can meaningfully improve motivation and conceptual understanding among young learners.

Through literature analysis, this study aims to evaluate the effectiveness of the guided inquiry learning paradigm in teaching science at the primary school level. The methodology used in this research is qualitative, characterized by a literature review that analyzes various publications related to the implementation of the guided inquiry model. The results of the analysis show that the inquiry learning approach is effective for increasing student learning achievement, improving science processes, and increasing student learning motivation in science subjects. This model facilitates students to be actively involved in the learning process while still receiving direction from the teacher. The results of this study indicate that a directed inquiry learning model can serve as an effective alternative for science learning in primary schools.
