Solar Distillation as a Sustainable STEM Tool: Bridging Theory and Practice

Abstract

This study addresses a gap in STEM education by integrating solar distillation as a sustainable, hands-on learning tool to enhance students’ comprehension of heat transfer concepts and increase their awareness of environmental challenges. Guided by Bruner’s constructivist theory, this project-inspired approach aims to bridge theoretical knowledge with real-world applications, particularly sustainability. Students participated actively in the solar still’s design, construction, and analysis phases, allowing them to apply scientific principles in practical contexts. The findings demonstrated that students understood heat and mass transfer concepts more profoundly and developed an appreciation for renewable energy technologies and sustainable practices. Additionally, the project highlighted the impact of external climatic conditions on system performance, promoting an awareness of environmental factors affecting sustainable solutions. This research illustrates the potential of combining constructivist learning with sustainable technology education, preparing students to address pressing global issues such as water scarcity and energy conservation.
