Elementary school students often prefer sugary drinks over water, which increases the risk of dehydration and various health problems. This highlights the need for engaging and interactive educational media to improve students’ knowledge and shape positive attitudes toward the importance of drinking water from an early age. This study employed a pre-experimental design with a one-group pretest-posttest approach. The sample consisted of 38 fifth-grade students at SDN 79 Bengkulu City, selected using the total sampling technique. Data were collected using knowledge and attitude questionnaires, while the intervention was carried out through the Game Change of Habits educational game. The data were analyzed using the Wilcoxon test. The results showed an increase in students’ average knowledge scores from 57.72 to 97.02 and attitude scores from 36.53 to 54.63 after the intervention. Statistical analysis revealed a p-value = 0.000 (p < 0.05), indicating a significant effect. These findings demonstrate that educational games are effective in enhancing understanding and fostering positive attitudes toward regular water consumption. It is recommended that educational games be used as an alternative strategy for health promotion in elementary schools. Teachers and health workers are encouraged to integrate such media into learning activities to instill healthy drinking habits from an early age in a sustainable manner.
