Embodiment Construction

[0024] A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0025] Such as Figure 1 to Figure 6 As shown, a kind of buoyancy experiment device of physics teaching provided by the embodiment of the present invention comprises:

[0026] Box 10, such as figure 1 As shown, it includes a partition 11 and a separation plate 12. The box body 10 has a storage chamber with an upper opening, and the partition 11 divides the storage chamber into a first storage chamber and a second storage chamber for holding a low-concentration solution. Partition plate 11 is vertically arranged in the storage chamber, and separation plate 12 divides the second storage chamber into a third storage chamber and a transition chamber 13 for holding a high-concentration solution. Separation plate 12 is horizont...

Abstract

The invention discloses a buoyancy experiment device for physics teaching, and belongs to the field of experiment apparatuses. The device comprises a box body and a communication device, wherein the box body comprises a clapboard and a separating plate; a storing chamber of which the upper part is opened is formed in the box body; the clapboard is used for dividing the storing chamber into a firststoring chamber and a second storing chamber which are used for storing low-concentration solutions; the communication device comprises a rocking rod, a connecting rod, a connecting rope and a rubberplug; the rocking rod is rotatably arranged on the box body; one end of the connecting rod is fixedly connected to the rocking rod; one end of the connecting rope is connected to the other end of theconnecting rod, and the other end of the connecting rod is connected to the rubber plug; the rubber plug is connected to a port of the connecting pipe through a connecting part; a draining hole is formed in the connecting part. According to the device, experimenting objects can be replaced to realize gradual change of the concentration; when the concentration is low, the objects are sunken to thebottom; when the concentration is high, the buoyancy increases, and the buoyancy to the objects is high, and the objects floats; the vision effect is good; and the direct feeling is improved.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a buoyancy experimental device for physics teaching. Background technique [0002] The law of buoyancy of an object, also known as Archimedes' law, according to Archimedes' principle, an object immersed in a liquid is subject to an upward buoyant force, and the buoyant force is equal to the gravity of the object displacing the liquid, namely F 浮 =G 液排 = ρ 液 wxya 排 . where V 排 Indicates the volume of liquid displaced by an object. It is a very important law in physics. In teaching, this law is relatively abstract and difficult to understand. Because buoyancy is related to the volume of the object, the acceleration of gravity and the density of the solution, and These factors are generally not easy to regulate and control. In the process of scientific experiments, the principle of single variable is generally followed, otherwise it is not easy to judge the variation of th...
