Abstract

This activity introduces two analogical learning models, Rock-Paper-Scissors (RPS) and LEGO brick simulations, to support high school students’ conceptual understanding of chemical kinetics. The RPS game models energy distribution and collision frequency through score-based interaction, while the LEGO activity represents molecular collisions and reaction progress using color-coded brick combinations. Students analyze their results by graphing energy distributions and tracking reactant depletion, reinforcing key kinetic concepts. The activities were implemented with grade 10–11 students. Although pre/post-assessment scores showed no statistically significant improvement, qualitative data from classroom discussions and worksheet responses indicated increased engagement and improved conceptual reasoning. These low-cost, adaptable tools serve as effective conceptual bridges when paired with teacher-guided reflection and inquiry-based discussion.
