Abstract:

Low-cost hydrogen technologies provide a powerful opportunity to engage students in future-oriented science education and to address the global transition toward sustainable energy. In this contribution, we present a modular teaching sequence designed to help secondary-school learners understand the limitations of fossil fuels and explore hydrogen as a viable alternative energy carrier. The instructional narrative begins with the combustion of fossil fuels in conventional engines and leads students—step by step—toward the challenges and promises of a hydrogen-based mobility system.

To foster hands-on learning, we developed ultra-low-cost experimental setups that allow learners to investigate hydrogen production and conversion with everyday materials. A key innovation is a fully functional electrolyzer built from a simple Tic-Tac box, which can be transformed into a hydrogen fuel cell within minutes [1]. This approach significantly reduces the financial and logistical barriers that often prevent schools from engaging with electrochemical technologies. It also empowers students to conduct authentic scientific inquiry and critically evaluate the role of hydrogen in the energy transition.

The presentation will showcase selected elements of the teaching unit through live demonstrations. Instead of relying on traditional lecture formats, the session integrates humor, storytelling, and performative elements inspired by science-slam culture. This format not only increases student motivation but also demonstrates how creative communication can enhance the accessibility and impact of STEM education.

By combining low-cost experimental innovation, contemporary energy topics, and engaging science communication, this contribution illustrates how chemistry education can help learners develop informed perspectives on sustainable technologies and their societal relevance.
