Abstract
The utility model relates to an experiment appliance for students to realize water pressure, which is characterized in that the utility model is composed of a high-weir funnel with scales, a plastic tube, and a tube plug. The utility model has the advantages of good experimental effect, simple structure, low cost, small size, convenient operation, convenient storage, etc.
Description
The utility model relates to a kind of apparatus of using for student experimenting, especially for the experiment apparatus of the relation of factors such as the pressure of understanding water and water level, genus student appliance field.
The laboratory of the natural science knowledge of present school, majority is demonstrated on the dais by teacher, demonstration, in conjunction with the book knowledge explanation, the student can only watch understanding, and the student can not oneself operate, therefore it is more superficial that study understanding is understood knowledge, is difficult for keeping firmly in mind, and the teaching aid that the while teacher uses is not suitable for the student and does it yourself to operate on the classroom, price is more expensive, complex structure.
The purpose of this utility model provides a kind of pressure experiment apparatus for students ' understanding water for the shortcoming that overcomes above-mentioned prior art just with deficiency, thereby the student is integrated theory with practice, and improves manipulative ability, reaches best results of learning.
The purpose of this utility model is achieved in that
The pressure experiment apparatus of students ' understanding water is characterized in that it is made up of high weir funnel, plastic tube and the pipe close of band scale, has the plastic tube of the aperture of different distance on the hopper outlet connection lower part wall, and seal with pipe close the plastic tube bottom.
This plastic tube plastic tube that can extend at the top, the pipe adapter by band boss platform inserts in two pipes and is connected as a single entity.
Owing to take technique scheme, make to the utlity model has that experiment effect is good, simple in structure, cost is low, volume is little, be convenient to receive the root of Dahurian angelica, easily grasp the easily advantage of study, can cultivate students'experiment ability and inductive generalization ability simultaneously.
Description of drawings:
Fig. 1 is the pressure experiment apparatus structural representation of water;
Fig. 2 is the pressure experiment apparatus of the water of lengthening plastic tube.
Below in conjunction with accompanying drawing embodiment the utility model technology is further specified:
The pressure experiment apparatus of students ' understanding water, as shown in Figure 1, it is by the high weir funnel of band scale, plastic tube, pipe close is formed, funnel (1) outlet connects aperture (2) plastic tube (3) that has different distance on the tube wall of bottom, seal with pipe close (5) the plastic tube bottom, in order to continue to make study further understand the variation of increasing height of water level and pressure again, can be above former plastic tube top lengthening one section plastic tube (6), this pipe can be with aperture, pipe adapter (7) ' connection by band boss platform, pipe adapter stretched in two pipes be connected as a single entity, as shown in Figure 2, observe the situation of change of the current (4) of ejection current (8) and Fig. 1 again, the student is further understood increase height of water level, its ejection pressure is big more, and how the pressure that makes the student think deeply water after class to be utilized by people in productive life, improves experimental ability and inductive generalization ability by experiment.
Claims (2)
1, the pressure experiment apparatus of students ' understanding water is characterized in that it is made up of high weir funnel, plastic tube and the pipe close of band scale, has the plastic tube of the aperture of different distance on the hopper outlet connection lower part wall, and seal with pipe close the plastic tube bottom.
2, experiment apparatus according to claim 1 is characterized in that the described plastic tube plastic tube that can extend at the top, and the pipe adapter by band boss platform inserts in two pipes and is connected as a single entity.
