Understanding static electricity can be challenging for elementary students due to its abstract nature. As the ability to explain scientific phenomena is a key indicator of scientific literacy, contextual and interactive learning experiences are essential. This study aimed to explore the level of understanding of the concept based on a case study in a Malaysian primary school. This study investigated the implementation of a guided inquiry-based static electricity experiment and analyzed the scientific literacy outcomes of Grade 3 students in a Malaysian elementary school. Using purposive sampling, 28 students participated in a simple practicum that involved using a ruler and paper pieces, supported by a worksheet and a nine-item Likert-scale questionnaire to assess their scientific literacy. Data analysis confirmed normal distribution, with literacy scores indicating strong performance: 81% in understanding and explaining phenomena, 85% in designing and evaluating scientific inquiry, and 88% in applying scientific information for decision-making. Skewness values of 0.035, -0.836, and -0.917, respectively, suggest consistent data patterns. Despite overall positive results, the lowest score highlights the need to strengthen concept understanding. Findings demonstrate that simple, experiment-based learning can foster cognitive development and scientific literacy, emphasizing the role of teacher guidance in linking everyday experiences to scientific concepts.

Physics is one of the subjects that students find difficult to understand. Physics is not only a science that requires memorization, but also requires a deep understanding of its concepts. Physics studies natural phenomena physically and is written in mathematical form, thus emphasizing the aspect of conceptual understanding. In addition to conceptual understanding, another important aspect is student involvement in the learning process. One important topic that needs to be studied is mirrors. The topic of mirrors will be easier to understand if it is practiced so that students can understand it better. Therefore, Phet simulation media is needed. The purpose of this study is to explain the differences in understanding the concept of mirrors between students who use PBL plus PhET and students who use regular PBL, as well as to analyze the differences in student engagement in learning about mirrors between students who use PBL plus PhET and students who use regular PBL. The population in this study consisted of 64 students from MA Mathalibul Huda and 64 students from MA Darul Hikmah Menganti. Data collection methods included tests, observations, and documentation. The collected data were analyzed using N-Gain and t-tests. Based on the research results, there is a difference in concept comprehension between the PBL Plus and regular PBL learning models, with the PBL Plus class achieving a higher average post-test score of 81.03, while the regular PBL class achieved an average post-test score of 62.31. The N-Gain value - Gain of the regular PBL class was 0.22, while the N-Gain value of the PBL Plus class was 0.58, which is categorized as moderate. The T-test resulted in a sig value (2-tailed) of 0.00 < 0.05. Thus, it can be concluded that the PBL Plus learning model is effective in improving students’ conceptual understanding of mirror material. In addition, there is also a difference in student learning engagement between the PBL Plus class and the regular PBL class, where PBL Plus shows that the category of active students is higher than that of the regular PBL class based on 4 indicators of student learning engagement.
