Physical principle teaching display device and method

The invention provides a physical principle teaching display device and method. The physical principle teaching display device comprises a containing frame, a power generation assembly, a pushing structure and a display structure. A part of the lifting floating body floats on the water surface, the lifting floating body can move up and down under the action of up-down fluctuation of the water surface of the liquid water, the up-down movement of the lifting floating body can correspondingly drive a hinged part to turn over and swing, and correspondingly, a driving rod set enables a driving wheel and a rotating rod to rotate; and when the rotating rod rotates, electric energy is formed in the generator so that a current is formed and is visually displayed on the display lamp. Moreover, students can observe the stirring condition of the liquid water in the containing frame through the containing frame, and the brightness of the display lamp is correspondingly improved when the fluctuation degree is aggravated so
