LHK students and teachers attended the Primary School STEAM Day, teaching students how to make radio-controlled boat and conduct inter-class competitions. Our students demonstrated great patience and kindness, carefully assisting the primary students in assembling the boats step by step, ensuring that even beginners could successfully complete their projects and participate in the competition. The atmosphere on-site was both lively and warm. We hope that through this activity, students can experience Physics principles and engineering design, inspiring their interest in technology and creativity.
