Abstract
The utility model provides an intermolecular gap demonstrator for primary school science, relating to the technical field of teaching aids and learning aids of the primary school science. The intermolecular gap demonstrator comprises a transparent suction tube, an injector and a plug, wherein the transparent suction tube is adhered to a needle head connecting bulge; the tail end of the injector is sealed by the plug; two or more than two types of different liquid is added into the injector and is vibrated and the descending of a liquid level can be clearly observed, so that a fact that a gap exists between molecules is demonstrated. Compared with the prior art, the intermolecular gap demonstrator can be manually manufactured by students through utilizing wastes and common articles in our lives, thereby thirst for knowledge and curiosity of students can be satisfied. The intermolecular gap demonstrator is simple in structure and is the teaching aid which has a popularization value.
Description
Technical field
The utility model relates to a kind of primary school science teaching aid and learning aid, is that primary school's science is with intermolecular interval demonstration device specifically.
Background technology
In primary school's science teaching; To give the intermolecular interval of student explain, like the interval between the hydrone, the interval between the alcohol molecule etc.; How to utilize the old and useless article in the life to show; Be the problem of pendulum in face of the science teacher, lack the teaching aid of this respect in can existing teaching, be unfavorable for popularizing and demonstration of scientific knowledge.
The utility model content
The purpose of the utility model is the deficiency that lacks cheap intermolecular interval teaching aid to existing, provides a kind of and utilizes the homemade primary school of discarded object science in the life with intermolecular interval demonstration device.
The purpose of the utility model realizes through following technological means: primary school's science is made up of transparent suction pipe, syringe and stopper with intermolecular interval demonstration device, transparent suction pipe and the bonding connection of syringe needle connection bump, and injector tip is used plug seal; Through to the inner different liquids that adds two or more of syringe, vibrate, can clearly see the decline of liquid level, thereby show the spaced fact between the molecule.
Compared with prior art the utlity model has following tangible advantage: utilize discarded object and common article in the life, can do it yourself to make, satisfied student's aspiration to knowledge and curiosity, simple in structure, be a kind of teaching aid that promotional value is arranged.
Description of drawings
Fig. 1 is the utility model synoptic diagram.
Wherein 1. transparent suction pipes, 2. syringe needle connection bump, 3. syringe shell, 4. injector tip, 5. stopper.
Embodiment
Below in conjunction with description of drawings the utility model is done further to describe in detail:
Primary school's science with the making use of intermolecular interval demonstration device is: get one of disposable syringe, pull out syringe needle, a transparent suction pipe 1 is bonding with syringe needle connection bump 2 usefulness glue, and injector tip 4 usefulness stoppers 5 jam-packs are just processed demonstration device; During use, in syringe shell 3, fill with two kinds of different liquids (like tap water and alcohol), block 1 mouthful in transparent suction pipe with thumb, turned upside down holds up several times again, can see that promptly transparent suction pipe 1 part liquid level descends, thereby the intermolecular interval that has is described.
In a word, the utility model provides primary school's science with intermolecular interval demonstration device.The above; Be merely a part of embodiment of the utility model; The protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
Claims (1)
