Abstract

This study examines the effectiveness of Problem-Based Learning (PBL) through a rainbow rain experiment to improve students' understanding of matter states and changes at SDN 188 Pekanbaru. Using a qualitative approach, 25 fourth-grade students were observed through worksheets, documentation, and pre-test–post-test design. The experiment used water, food coloring, and cooking oil to visualize density and solubility concepts. The learning applied five PBL syntaxes: problem orientation, student organization, guided investigation, developing artifacts, and problem-solving evaluation. Results showed average scores increased from 48 to 75 (56.25%), with all students scoring above 60. Students were actively engaged, showing improved critical thinking and scientific skills. The study concludes that combining PBL with simple, hands-on experiments can be an effective and practical science teaching strategy in elementary education.
