Abstract
The utility model relates to a physics teaching aid for middle schools, which belongs to stationery aids. The physics teaching aid comprises a base composed of a slide way board and a support frame, wherein one end of the slide way board is connected with the upper end of the support frame through hinges, and the other end thereof naturally sags on ground; the upper half part of the slide way board is provided with a timer; one side of the timer is provided with a timing switch, and the other side is provided with a reset switch. The timer is respectively connected with the timing switch and the reset switch through conducting wires. The lower half part of the slide way board is provided with two metal sheets, wherein one metal sheet is connected with the timer through the conducting wire and the other metal sheet is connected with the timing switch through the conducting wire. Moreover, one side edge of the slide way board is provided with a scale line. The utility model has the advantages of simple structure and strong operability, and average speed values can be obtained in a testing way. The utility model not only is convenient for teachers to quickly accomplish teaching tasks, but also can raise students' learning interest and action ability. The utility model is very helpful for building the students' problem parsing and problem solving abilities.
Description
Technical field
The utility model relates to a kind of physics teaching in secondary school apparatus, particularly relates to a kind of physics teaching in secondary school apparatus of testing average velocity, is to the replenishing of existing physics teaching in secondary school apparatus kind, and belongs to school supply and stationery, and suitable middle school student and teacher use in teaching.
Background technology
At present, the used teaching aid of people is a lot, but function singlenesses all just designs at the content that needs separately to show.The notion of average velocity is important and one of the content of beyonding one's depth in the physics teaching in middle school, and student and teacher press for teaching aid targetedly, yet but are difficult to find this class teaching aid on market.Its as a result the teacher in explanation during average velocity, always adopt and impart knowledge to students according to the mode of originally explaining and publicising, more abstract hard to understand, the student lacks the chance of starting to test again, the enthusiasm that can not mobilizing students initiatively participates in, be helpless to cultivate students ' analysis problem and problem-solving ability, thereby bring certain difficulty, even have influence on student performance and learning interest to teaching.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, improve by research, provide a kind of physics teaching in secondary school apparatus that can test average velocity, this novel physics teaching in secondary school apparatus is simple in structure, workable, can test out average velocity, both be convenient to the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.
The technical scheme that the utility model provides is: this physics teaching in secondary school apparatus, include a base, be characterized in that described base is made of chute board and bracing frame, wherein be connected with the upper end of bracing frame by hinge on the end of chute board, its other end naturally vertically, the first half at described chute board is provided with a stopwatch, one side of this stopwatch is provided with time switch, its opposite side is provided with the switch that makes zero, stopwatch is connected with the switch that makes zero with time switch respectively by lead, Lower Half at described chute board is provided with the twice sheet metal, stopwatch is connected with wherein sheet metal by lead, time switch is connected with wherein another road sheet metal by lead, also is provided with scale mark on the side of described chute board.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, workable, can test out average velocity, both be convenient to the teacher and finished teaching task quickly, improved the interest and the manipulative ability of student's study again, very helpful to cultivating students ' analysis problem and problem-solving ability.
Description of drawings
Accompanying drawing is the structural representation of an embodiment providing of the utility model.
Number in the figure: 1. bracing frame, 2. stopwatch, 3. chute board, 4. time switch, 5. sheet metal, 6. sheet metal, switch 7. makes zero.
Embodiment
As shown in the figure, this physics teaching in secondary school apparatus that the utility model provides, include a base that constitutes by chute board 3 and bracing frame 1, wherein be connected by the upper end of hinge on the end of chute board 3 with bracing frame 1, its other end naturally vertically, the first half of chute board 3 is provided with a stopwatch 2, one side of this stopwatch 2 is provided with time switch 4, its opposite side is provided with the switch 7 that makes zero, stopwatch 2 is connected with the switch 7 that makes zero with time switch 4 respectively by lead, the Lower Half of chute board 3 is provided with the twice sheet metal, stopwatch 2 is connected with wherein sheet metal 5 by lead, time switch 4 is connected with wherein another road sheet metal 6 by lead, also is provided with scale mark on the side of chute board 3.
During demonstration, open bracing frame 1 earlier, make chute board 3 form an inclined-plane, and make stopwatch 2 enter time status, model car is placed the time switch 4 at starting point place, hand one pine, model car starts, and time switch 4 picks up counting.When model car the reach home sheet metal 5 and the sheet metal 6 at place, stopwatch 2 stops timing automatically, distance of being passed by by model car and required time, just can draw the average velocity of car.
