Through a research project of exploring the physics concept in Techno Park, this study was manifested. The authors specified the discussion into “Gravitram". It is a complex system in which an electric motor lifts metal balls to the top of the system, so each ball experience the law of conservation of energy. Rationally, the authors adopted the qualitative thematic paradigm in the research methodology. Documentation study including 92 pre-service physics teachers in Surabaya as participatory action research through photo-elicitation, video analysis, and content analysis of electronic resources were used in the data collection. For a clear explanation, the findings and discussion are started from the history of the gravitram system, gravitram in the world, and the physics analysis of the system itself. The discussion is also exploring further the role of this system as a part of physics leisure, outdoor learning, or both of them. Copyright © 2020 EAI
