Description

A kind of scientific toy

Technical field

The utility model relates to the teaching and experiment equipment technical field, is specifically related to a kind of scientific toy.

Background technology

Adopt flexile form of teaching, allow the student easier, get more information about the thought that has embodied modern teaching with learning knowledge, especially in the elementary and middle school teaching in period, because some scientific knowledge, concept are more abstract, dry as dust, add the vivaciously active of student, for a long time sustained attention power, so adopt flexile happy teaching method, be conducive to excite student's desire for knowledge and consolidate the knowledge of acquiring.In now teaching; usually can by some experiment equipments allow the student get more information about and learn object center of gravity and stability concern scheduling theory knowledge; there is a game a lot of people all to play; holding a long rod erects at the palm of the hand; by the horizontal jitter of palm keep rod in the palm of the hand balance and can not fall down; the relation of object center of gravity and stability is probed in the similar game how we utilize; may also be no small input concerning some schools for special experiment equipment; and the few of interest of some experiment equipment itself; student couple is not high with the enthusiasm of experiment, takes exercise limited to student's manipulative ability.

The utility model content

It is a kind of convenient and practical that technical problem to be solved in the utility model is to provide, and can excite student play passion and scientific exploration interest, improves the scientific toy of students ' practical ability.

Technical problem to be solved in the utility model realizes by the following technical solutions.

A kind of scientific toy is characterized in that: comprise the lower beam made from thin penholder, with the upper boom of thin penholder making and the thick bar made from thick penholder, the inside of described thick bar is provided with iron block.

The diameter of section in the same size of described upper boom and lower beam.

Be fixedly connected with between described iron block and the thick bar.

The beneficial effects of the utility model are: the utility model is easily to look for material to be made at one's side with the student, and simple in structure, cost is low; Experiment instrument is made easily, is fit to student's manual fabrication, has tempered student's manipulative ability; Toy is novel, and is interesting strong, processing ease, safety when playing; The phenomenon that produces is obviously directly perceived.

Fig. 1 is the utility model structural representation.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1, a kind of scientific toy comprises the lower beam 1 made from thin penholder, and with the upper boom 2 of thin penholder making and the thick bar 3 made from thick penholder, the inside of thick bar 3 is provided with iron block 4.The diameter of section in the same size of upper boom 2 and lower beam 1.Be fixedly connected with between iron block 4 and the thick bar 3.

When finger withstands lower beam 1 bottom, by the finger horizontal jitter, be difficult to keep the upright of lower beam 1; When being placed on upper boom 2 on the lower beam 1, withstand lower beam 1 bottom with finger again, by the finger horizontal jitter, can keep the upright of lower beam 1 and upper boom 2 in the short time; When being placed on the thick bar 3 that iron block 4 is housed on the upper boom 2 again, withstand lower beam 1 bottom with finger again, by the finger horizontal jitter, can keep easily the upright of lower beam 1, upper boom 2 and thick bar 3.

More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.

Claims (3)

1. scientific toy is characterized in that: comprise the lower beam made from thin penholder, and the upper boom made from thin penholder and the thick bar made from thick penholder, the inside of described thick bar is provided with iron block.

2. a kind of scientific toy according to claim 1 is characterized in that: the diameter of section in the same size of described upper boom and lower beam.
