Display device for chemistry teaching and use method thereof

Abstract

The invention discloses a display device for chemistry teaching and a use method thereof, comprising a storage seat, a display case and a top plate, wherein a support pad is bonded at four corners ofthe lower end of the storage seat. A beneficial effect is as follow: a storage seat, a hydraulic lifting lever, a hydraulic motor III, a fixing groove and a fixing block are arranged, convenient storage of the device can be realized, the invention can effectively save the volume of the device, so that the device can be carried more conveniently; the sliding support seat I, the sliding support seatII, a hydraulic motor I, a hydraulic motor II, a glass cover, a hydraulic push rod I and a hydraulic push rod II are arranged, it can realize the convenient display of molecular model and glass testtube, and can effectively prevent the peculiar smell from escaping from the reagent in the glass test tube during the display process, by setting up a video player, an electronic pen and a display screen and combining manual teaching with video teaching, not only the students' enthusiasm can be improved, but also the efficiency of display teaching can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of chemistry teaching tools, in particular to a display device for chemistry teaching and a use method thereof. Background technique [0002] Teaching aids, referred to as teaching aids, refers to the general term for all kinds of utensils used to enable students to understand the teaching content intuitively and visually, as well as the utensils used by teachers when teaching. Teaching aids can improve students' interest in learning, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking abilities. It is generally divided into three categories: ordinary teaching aids, special teaching aids, and children's teaching aids. Among them, in the process of chemistry teaching, in order to enable students to better understand knowledge, it is often necessary to display the separation model or glass test tube. However, the existing display devices for chemistry teaching...

AI Technical Summary

Problems solved by technology

Among them, in the process of chemistry teaching, in order to enable students to better understand the knowledge, it is often necessary to display the separation model or glass test tube. However, the existing display devices for chemistry teaching are large in size and inconvenient to carry during use. A single display of molecular models or glass test tubes can be carried out, and the display environment is often polluted by the escape of peculiar smell from the reagents in the glass test tubes during the display process. In addition, in the process of display teaching, manual teaching can only be used for display teaching , the enthusiasm of the students is often reduced due to the single teaching method, which leads to the low efficiency of the demonstration teaching. Therefore, there is an urgent need for a chemical teaching display device to solve the existing problems.
