Abstract
The utility model discloses a demonstration resonance phenomenon's teaching experiment device, this experimental apparatus include the base, are fixed in first pillar, second pillar on the base, connect in the crossbeam of first pillar with second pillar upper end, through the fixed bar glass board of connecting piece on the crossbeam, the lower limb of bar glass board is equipped with the aperture that the spacing distance is the same side by side, the aperture passes through the string and links to each other with the steel ball. Owing to adopt above -mentioned structure, demonstration resonance phenomenon that can be visual in image, teaching in joy arouses student's interest in learning, and the student of being convenient for understands abstract knowwhy, improves results of learning.
Description
Technical field
The utility model belongs to teaching and experiment equipment technical field, particularly relates to a kind of experiment device for teaching of demonstrating resonance phenomenon.
Background technology
In current teaching, be a teacher when explaining resonance effect, for the student just touching this respect knowledge, indigestion, brings certain difficulty to teaching, understands knowwhy intuitively to allow student image, motivate students' interest in learning, improve classroom teaching effect, we are in teaching for many years, have devised a kind of experiment device for teaching of demonstrating resonance phenomenon.
Summary of the invention
The purpose of this utility model is to provide a kind of experiment device for teaching of demonstrating resonance phenomenon that can be vivid.
The purpose of this utility model is achieved through the following technical solutions, this experimental provision comprises base, the first pillar be fixed on base, the second pillar, be connected to the crossbeam of the first pillar and the second pillar upper end, described crossbeam fixes a strip glass plate by web member, the lower limb of described strip glass plate is provided with the identical aperture of spacing distance side by side, and described aperture is connected with steel ball by cord.
When swinging the arbitrary steel ball in group with hand, other steel balls swing all simultaneously, but when in swing ball, pendulum length resonates with the equal person of pendulum length of the arbitrary ball put with hand, the amplitude of pendulum is maximum.
The beneficial effects of the utility model, owing to adopting said structure, demonstrating resonance phenomenon that can be visual in image, teaches through lively activities, motivates students' interest in learning, and is convenient to student and understands abstract knowwhy, improves results of learning.
Accompanying drawing explanation
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing
Fig. 1 is schematic diagram of the present utility model
In figure: 1, base 2, first pillar steel ball 3, second pillar 4, crossbeam 5, web member 6, glass plate 7, aperture 8, cord 9 steel ball
Embodiment
As shown in Figure 1, this experimental provision comprises base 1, the first pillar 2, second pillar 3 be fixed on base 1, be connected to the crossbeam 4 of the first pillar 2 and the second pillar 3 upper end, crossbeam 4 fixes a strip glass plate 6 by web member 5, the lower limb of strip glass plate 6 is provided with the identical aperture 7 of spacing distance side by side, and aperture 7 is connected with steel ball 9 by cord 8.When swinging the arbitrary steel ball in group with hand, other steel balls swing all simultaneously, but when in swing ball, pendulum length resonates with the equal person of pendulum length of the arbitrary steel ball put with hand, the amplitude of pendulum is maximum.
