The DIY Periscope Light Reflection Physics Working Model is specially designed to help students understand the laws of reflection through hands-on experimentation. Instead of just reading theory from textbooks, students can visually observe how light rays reflect using two plane mirrors positioned at 45° angles inside the periscope structure. This STEM educational science kit is ideal for science exhibitions, CBSE practical submissions, classroom demonstrations, and investigatory projects. It helps students clearly understand mirror reflection, light path direction, and the basic working principle of optical instruments. Crafted from premium laser-cut MDF, the model features a strong slot-fit design for easy assembly without complicated tools. The smooth edges ensure safe handling, making it suitable for school environments. Whether preparing for a science fair or enhancing classroom learning, this periscope working model builds conceptual clarity, boosts presentation confidence, and makes learning optics engaging and interactive.
