Electric Birdcage Course Presentation

   Visual stay: It refers to when a person's eyes are watching a moving object, especially a smaller object, for a longer period of time, the shape, size, and color of the object seen will leave a deep impression on the memory system of the brain. It will lead to the phenomenon of "distraction", and if the object seen by the eyes is quietly moved away, the person's eyes will still feel that the object is still in their line of sight within a very short time (about 0.1s).
This phenomenon, where after quietly moving the object in front of your eyes, your eyes still feel as if the object is still in your line of sight for a moment, is known as "visual persistence."

Experimental Objectives: 1. To study the visual afterimage characteristics of the human eye. 2. To cultivate children's ability to operate and analyze.
Experimental Cognition
The phenomenon of visual persistence was first discovered by the Chinese, and the tapestry horse lamp is one of the earliest examples of visual persistence in historical records. By the Song dynasty, there were already tapestry horse lamps, which were then known as "horse riding lamps." When the eye sees a series of images, it holds one image at a time. When an object moves quickly, after the images the person sees disappear, their eyes can still retain the image for about 0.1-0.4 seconds.
Battery box: As the name suggests, it is a box used to install and fix the batteries, which is the device for outputting battery power.

DC motor: composed of stator and rotor, a DC motor converts direct current electrical energy into mechanical energy. Due to its excellent performance in speed regulation, it is widely used in electric power traction. DC motors are classified by their excitation methods into permanent magnet types.
He Li and self-motivation are three categories, among which self-motivation is further divided into parallel excitation, series excitation, and multiple excitation.
Switch: A device for turning power on and off.

Experiment Report:
When the human eye observes scenery, the light signal enters the brain nerves, and it takes a short period of time. After the effect of light ends, the visual image does not disappear immediately. This residual vision is called "afterimage," and this phenomenon of vision is called "visual persistence." Its specific application is in the shooting and screening of movies. The reason is caused by the reaction speed of the optic nerve, which is twenty-fourth of a second. It is the basis for the formation and dissemination of visual media such as animated movies.
Vision is actually achieved by the lens of the eye forming an image, by the photoreceptive cells sensing light, and by converting the light signals into electrical impulses, which are then transmitted back to the brain to produce human vision. The photoreceptive cells' ability to sense light depends on certain photopigments, and the formation of these photopigments requires a certain amount of time, which is the mechanism behind the pause in vision.
