Where Am I
★Exhibit Content: A field orientation method using the pattern of the sun's shadow ★Interaction: Electromechanical interaction ★Operation: Select a prop and place it at the center of the base plate; press the "Start" button, mark the two shadow endpoints; press the "Judge" button to display the correct direction; press the "Clear" button to erase the marks. ★Exhibit Description: The exhibit consists of a box-type display stand, an arc-shaped lamp set simulating the sun's motion, an electromagnetic writing pad, marking props, a direction display module, and a function button group. It is a recommended exhibit from the KexMall exhibit store. The display stand integrates a lighting device simulating the sun's apparent motion and a magnetic recording panel, along with a vertical pole prop. Visitors stand the prop upright at the center of the panel. After pressing the start button, the simulated sun lights illuminate sequentially along the arc, and the prop's shadow shifts accordingly. Visitors use their fingers to mark the two shadow endpoint positions on the writing pad. After pressing the judge button, the correct direction light box illuminates to verify the judgment. After the experience, the clear button can be pressed to erase the records. Through interactive operation, the exhibit teaches visitors the practical skill of using the sun's shadow to determine direction without a compass or map. ★Scientific Principle: In the Northern Hemisphere, the sun rises in the east and sets in the west daily in apparent motion, and the shadow of an object on the ground moves synchronously with the sun's position: in the morning, the shadow points slightly west and gradually shortens; at noon, the shadow is shortest; in the afternoon, the shadow points slightly east and gradually lengthens. By recording the shadow endpoints of the same object at different times, the first marked point corresponds to the west side, and the second to the east side, thereby determining the east-west direction and further deducing the north-south direction. This is a classic field orientation method using the sun's movement patterns. Combined with natural features such as tree rings and vegetation orientation, it can effectively determine direction outdoors without tools, and is a basic skill for outdoor survival and geographic practice.
