Abstract
The utility model provides a teaching aid for demonstrating a sinking and floating principle of a submarine, comprising a bottle body with a bottle cover. The teaching aid is characterized in that a plurality of through holes (2) are arranged on the circumferential wall of the bottle body (1); a right-angle bending pipe (4) is inserted into the bottle body (1) through an inserting hole on the bottle cover (3); and one end of the right-angle bending pipe (4) in the bottle is connected with an air inlet of a balloon (5), while the other end is communicated with the atmosphere. All raw materials of the teaching aid are easy to obtain, and the teaching aid is simple to manufacture and easy to operate and can quite intuitively demonstrate a sinking and floating process of a submarine. Through a simple model and site explanations, the teaching aid not only is beneficial to the vivid teaching of teachers, but also can improve the learning interests of students and cultivate the practical ability of the students.
Description
Technical field
The utility model relates to teaching appurtenance category, specifically demonstrates the teaching aid of submarine sink-float principle.
Background technology
Submarine is extensively applied in the teaching because of the relation of buoyancy size in the utilization physics with volume.But because of its objective factor, the teaching material of existing explanation submarine sink-float principle, DeGrain, and can not intuitively observing is difficult to make student's proof procedure of buoyancy and pressure relation that undergoes.But, usually make the student well not understand, thereby bring certain difficulty, even have influence on student performance and learning interest to teaching with abstract appearance and complicated formula.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of teaching aid that is used to demonstrate submarine sink-float principle is provided.
The purpose of this utility model is achieved in that the teaching aid of described demonstration submarine sink-float principle, comprise the bottle that has bottle cap, on the perisporium of bottle, be provided with a plurality of through holes, right-angle bend is inserted in the bottle by the hole on the bottle cap, the end of right-angle bend in bottle links to each other with the air intake opening of balloon, and the other end is connected with atmosphere.
The beneficial effects of the utility model: choosing of all raw materials is easy to get, make simple, processing ease, unusual ocular demonstration submarine sink-float process, by simple model and on-the-spot explanation, both helped the teacher and vivo imparted knowledge to students, and can improve students'interest in learning again and cultivate students'ability for practice.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-bottle, 2-through hole, 3-bottle cap, 4-right-angle bend, 5-balloon.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.Among Fig. 1, the teaching aid of described demonstration submarine sink-float principle, comprise the bottle that has bottle cap, it is characterized in that: on the perisporium of bottle 1, be provided with a plurality of through holes 2, right-angle bend 4 is inserted in the bottle 1 by the hole on the bottle cap 3, the end of right-angle bend 4 in bottle links to each other with the air intake opening of balloon 5, and the other end is connected with atmosphere.
During use, get the vessel that more than half basin water is housed, pushing the submarine teaching aid downwards with hand is placed in the vessel, water can enter into bottle 1 from through hole 2, water in the bottle 1 is more and more, and its gravity is also increasing, and the submarine teaching aid sinks gradually, after filling water in the bottle 1, the submarine teaching aid just sinks to the bottom.At this moment, inflate in balloon 5 from top right-angle bend 4, the water in the bottle 1 can be pushed away from through hole 2, when balloon 5 becomes greatly gradually, the water in the bottle 1 is fewer and feweri, and its gravity is also more and more littler, and the submarine teaching aid floats gradually.
