Features Learning points included: reflection principle of light and rectilinear propagation of light. Type: physical optical reflection teaching tool suitable for classroom lessons, home experiments, and interactive demonstrations. Lens: 360degree rotatable lens for flexible viewing angles. Design: quickdetachable and expandable components for easy reconfiguration and scalable demonstrations. Package includes: 1 x Periscope Model. How this product solves problems Makes abstract optics concepts tangible by providing a visible, manipulable model that reveals how light reflects and travels in straight lines. Reduces preparation time for instructors with quickdetachable parts and straightforward assembly. Encourages active learning and repeated exploration through adjustable lens orientation and expandability. Typical use scenarios Classroom demonstration: Show the reflection principle and straightline propagation of light during a physics lesson, with students taking turns to observe and adjust the periscope. Home science activity: Use the periscope model for guided experiments that develop observation and analytical skills outside the classroom. Science fair or exhibit: Provide an interactive station where visitors can rotate the lens and see how reflection and rectilinear propagation change the viewing path. Practical details Function: physical optical reflection teaching tool that illustrates reflection and rectilinear propagation of light. Compatibility: designed for educational settings and handson learning environments. Assembly and operation: features quickdetachable, expandable parts and a 360degree rotatable lens to support multiple demonstration configurations. This periscope model delivers a clear, handson way to teach and explore fundamental optics principles while building observational and analytical skills.
