This action research study investigated the effectiveness of active learning strategies in enhancing the conceptual understanding of atoms and molecules among 8th standard students. The study addressed the persistent challenge of teaching these abstract concepts, which are often difficult for students to visualize and comprehend through traditional lecture methods. A one-group pre-test post-test design was employed with a sample of 20 students from Government High School, Hinkal, Mysuru. Active learning strategies--including group activities and role play, 3D molecular model construction, animated simulations, and concept mapping were implemented over a period of four weeks. Pre-test results revealed low conceptual clarity with a mean score of 6.72, indicating significant learning gaps. Post-intervention results demonstrated substantial improvement, with the mean score increasing to 14.4. Students displayed enhanced visualization of atomic structures, active participation, and improved retention of scientific concepts. The study concludes that active learning strategies are effective in addressing misconceptions, improving comprehension of abstract concepts, and fostering student engagement in science learning. These findings underscore the importance of integrating interactive, student-centered teaching methods into science classrooms to improve conceptual understanding and learning outcomes.
