Abstract:

This research initiative introduces an educational framework that merges the teaching, learning of physics and engineering principles via a comprehensive water-rocket science project. Central to this approach is a train-the-trainer model where university professors initially conduct didactic sessions for bachelor's degree-level educators, focusing on the physics underlying water-rockets, including simplified aspects of fluid mechanics, propulsion, electronics and aerodynamics. This initial phase aims to equip educators with the necessary depth of knowledge and pedagogical strategies to effectively adress complex concepts to their students. Additional didactic sessions are held on rocket sensor integration, programming for data collection, and exploring innovative design options for water-rockets. These sessions are designed to provide a global understanding of the engineering process, from conceptualization to implementation. Students then apply this knowledge in practical workshops, engaging in the hands-on construction of water-rockets and launch mechanisms, creating an environment of learning through doing.

The final stage of the project is an inter-school competition that not only assesses the water-rockets on the basis of maximum altitude achieved but also rewards innovative design proposals, promoting a blend of technical excellence and creativity. This multi-layered educational strategy, from educator preparation to student implementation and competition, underscores the significant pedagogical value of incorporating real-world engineering challenges into physics education.

This framework not only aims to deepen students' understanding of physics and engineering concepts but also seeks to enhance their skills in critical thinking, problem-solving, and teamwork. By adopting a comprehensive train-the-trainer model coupled with a hands-on project-based learning approach, the initiative demonstrated a increase in student engagement and interest in STEM fields, offering valuable insights into effective strategies for integrating science and engineering education.
