After weeks of construction\, soldering\, drilling\, wiring\, and engineering problem-solving\, the student teams will finally bring their submarines to life through the long-awaited water testing ses sion.\n\nThe workshop will begin with a brief recap of the key physical pr inciples explored throughout the project: buoyancy\, density\, pressure\, stability\, propulsion\, and electrical-to-mechanical energy conversion. M entors will highlight how each component of the submarine — from the PVC structure to the motor insulation — embodies these concepts in a tangib le engineering system.\n\nStudents will then proceed to the testing area\, where each team will place its submarine in the water for the first time. This phase will allow them to observe whether:\n\n-\nTheir submarines ach ieve proper buoyancy and balance\n\n-\nThe DC motors generate sufficient t hrust\n\n-\nThe remote control circuits respond correctly\n\n-\nThe waterp roofing techniques (wax\, tape\, plastic enclosures) hold under real condi tions\n\nThe objective is not only to test functionality\, but also to enc ourage students to identify the physical phenomena at play\, analyze unexp ected behaviors\, and propose design improvements — exactly as real engi neers do during prototyping.\n\nFollowing the tests\, students will comple te a post-workshop questionnaire\, similar to the initial diagnostic form they completed on the first day. This will allow mentors to measure how mu ch the participants’ conceptual understanding has improved — particula rly regarding forces\, buoyancy\, electromagnetism\, circuits\, and mechan ical motion. This evaluation will serve as both a pedagogical tool and an impact assessment for the Underwater Explorers program.\n\nThe session wil l close with a collective reflection\, where students will share their cha llenges\, discoveries\, and what they enjoyed most about building a functi onal underwater robot from scratch. This final conversation aims to reinfo rce scientific confidence\, highlight the value of perseverance\, and cele brate the creativity and teamwork that defined the entire project.\n\nThis workshop is not just about seeing submarines move — it is about confirm ing that hands-on STEM education empowers young learners to think critical ly\, solve problems\, and understand the physics that shape the world arou nd them.\n\nBarranquilla\, Atlantico\, Colombia LOCATION:Barranquilla\, Atlantico\, Colombia ORGANIZER:ieee@uninorte.edu.co SEQUENCE:50 SUMMARY:Final Workshop – Submarine Testing\, Evaluation & Learning Outcom es Assessment URL;VALUE=URI:https://events.vtools.ieee.org/m/514695 X-ALT-DESC:Description: <br /><p data-start="334" data-end="687">This final session marks the grand finale of the&nbsp\;<strong data-start="373" data -end="397">Underwater Explorers</strong> program &mdash\; a day dedicated to experimentation\, reflection\, and scientific validation.
