Abstract
A middle school physics teaching model comprises a base seat, a vertical column, a sphere and indicating arms, wherein the base seat is a circular disk which is made of cast iron, the lower end of the vertical column is tightly and fixedly connected to the center of the base seat, and the upper end of the vertical column is tightly and fixedly connected with the lower end of the sphere. The sphere is a round sphere which is made of steel plates and the surface of the sphere is provided with longitude lines and latitude lines in a drawing mode. The number of the indicating arms is four, wherein three of the four indicating arms have the same length, and the other indicating arm is 1.5 times the length of the other three indicating arms. The indicating arms are made of thin-walled aluminum alloy tubes, the upper end of each indicating arm is manufactured into an arrow shape, and a magnet is arranged inside each aluminum alloy tube at the lower end of each indicating arm. The lower surface of the magnet is a concave spherical surface, wherein the spherical surface is matched with the surface of the sphere, the lower end of each indicating arm can be absorbed on the surface of the sphere so that each indicating arm can perpendicularly stand on the surface of the sphere. The middle school physics teaching model has the advantages of being simple in structure and convenient to use. Therefore, the stress distribution situation of an object can be visually displayed on the teaching model. The teaching model is favorable for the improvement of teaching quality.
Description
Technical field
The utility model relates to a kind of teaching mode, relates to a kind of physics teaching in secondary school model specifically, and it mainly is used among the middle school physics classroom teaching.
Background technology
At present; In physics teaching in secondary school, in every case relate to make a concerted effort or movement locus at conplane force analysis, its theory explaination is easy to carry out force analysis through blackboard or drawing board; Yet objective things are present in the solid space; When needs are explained the stressed problem of three-dimensional space,, still there is a lot of classmates not understand even on drawing board, draw three-dimensional graph.Analyze the difference mostly reason wherein is students ' quality; They have nothing in common with each other in the understanding in stereo space; Many classmates are difficult to the force analysis in same plane or the Different Plane in the space is set up the stereoscopic three-dimensional model in a space in brain, thereby cause the part student to learn the force analysis in bad space, and fear force analysis; The content of indigestion teacher explanation is prone to produce the mood of being weary of studying in the course of time.Yet existing form of teaching is drawn in various force analysis on the blackboard by teacher, does not still have the force analysis that teaching aid is intuitively helped the students understand space.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of physics teaching in secondary school model is provided, to solve problem how in student's brain, to set up three-dimensional model in the existing mechanics teaching.
For realizing above-mentioned purpose, the utility model solves the problems of the technologies described above the technical scheme that is adopted and is: a kind of physics teaching in secondary school model is made up of base, column, spheroid, indicator stem; Wherein base be one by castiron disk, the center that is connected base that the lower end of column is fastening, the upper end of column and the lower end of spheroid are fastenedly connected; Spheroid is the ball of being processed by steel plate, is decorated with warp and parallel on the surface of spheroid, and the quantity of indicator stem is 4; 3 equal in length wherein, the length of another root are other 3 1.5 times, and indicator stem is processed by the thin-wall aluminum alloy pipe; Arrow shaped is processed in the upper end of indicator stem; Be provided with a magnet in the aluminium-alloy pipe of indicator stem lower end, the lower surface of this magnet is the sphere of a depression, and said sphere and spherome surface are complementary; The lower end of indicator stem can be adsorbed on the spherome surface, and makes the indicator stem standing upright on the surface of spheroid.
The method of application of the utility model is: teacher can be adsorbed on spherome surface with an indicator stem according to the needs of course and represent that one of object receives force direction; Also can several indicator stems be adsorbed on and represent several power and their relation of making a concerted effort on the spherome surface; Here 3 short indicator stems can be used for representing each component, and long indicator stem can be used for representing to make a concerted effort.
The beneficial effect of the utility model is: simple in structure, easy to use, can on teaching mode, show intuitively the distribution situation of object receiving force to help students understand the meaning of the question like this, and help to improve the quality of teaching.
