The invention discloses a clever bucket experimental device, comprising a water-storing bottle, an air-through pipe, a sleeve, a splint, a bottle cork, a water-storing bucket and a tap, wherein, AB glue is adopted to adhere required parts onto the water-storing bottle; the tap is fixed on a side wall of the water-storing bucket with attached screws; the water-storing bottle is arranged in a round hole of the splint, and two ends of the splint are arranged on the wall of the water-storing bucket. The clever bucket experimental device is characterized in that the water-storing bottle and water-storing bucket are made of transparent materials and can demonstrate the whole working process of the clever bucket; and can demonstrate what happens after an upper cut of the clever bucket is communicated with the atmosphere and also can demonstrate what happens when an water outlet of the water-storing bottle breaks away from the water level in the water-storing bucket. The clever bucket experimental device has the advantages of low manufacturing cost and simple structure and is suitable for demonstration experiments by teachers.
Description
A self-controlled barrel experimental device Technical field: The invention relates to a physics experiment device, in particular to a self-control barrel experiment device for junior high school physics liquid pressure teaching. Background technique: The pressure of liquid is the key content of junior high school physics teaching, and it is also a difficult point in teaching. The way to break through this difficulty is to let students do as many physical experiments as possible. As a wonderful example of the application of pressure in the textbook, students are required to observe the working process of the self-control bucket, and observe what happens when the water outlet of the bucket leaves the water surface and the top of the bucket opens an opening. However, no such experimental setup is currently available. Invention content: Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a self-control bucket experimental device...
