Our recent field trip to Hong Kong Ocean Park provided an exciting and educational experience for our F.5 Physics students, who enjoyed riding the roller coaster while learning about its engineering and physics principles. The design and construction of roller coasters require a deep understanding of engineering principles such as structural design, materials science, and safety regulations. By experiencing the ride firsthand and applying their knowledge of physics, our students gained a greater appreciation for the complex engineering behind it. We believe that this interdisciplinary approach to roller coaster design and construction can inspire students to pursue careers in engineering and demonstrate the practical applications of STEM education.
