Description

Technical Field

[0001] The present invention relates to the technical field of teaching aids, and in particular to a teaching aid for demonstrating gene mutation probability for popular science education and a demonstration method thereof. Background Art

[0002] A sudden, heritable change in a genomic DNA molecule (gene mutation). At the molecular level, a gene mutation refers to a change in the base pair composition or sequence of a gene's structure. Although genes are very stable, accurately replicating themselves during cell division, this stability is relative. Under certain conditions, a gene can suddenly change from its original form to a new one, meaning that a new gene suddenly appears at a specific location, replacing the original one.

[0003] Gene mutations can be harmful or beneficial, but most gene mutations are harmful. Harmful gene mutations may cause changes in plant traits. Plants also have gene mutations, which are caused by chemicals or radiation. Gene mutations are non-directional, and the results of gene mutations are both good and bad. When growing vegetables and fruits in the north and south, in order to make the plants more applicable or have better performance, biological varieties are often improved. Chemicals or radiation are usually used to cause plant gene mutations, which are manifested in the appearance of the plants, for example, through thick straw and taller plants. When plant science popularizers explain gene mutations to growers, they simply explain them through text, which is difficult for growers to imagine and understand. For this reason, we have designed a teaching aid for science popularization education to demonstrate the probability of gene mutation to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and propose a teaching aid for demonstrating the probability of gene mutation for popular science education and a demonstration method thereof. The teaching aid replaces the gene mutation by the change of the color of the flash light, so that the demonstration of gene mutation is clearer and more effective in popular science education. The teaching aid can also protect the plant model and make it less likely to be damaged.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A teaching aid for demonstrating gene mutation probability for popular science education includes a teaching box, two box plates rotatably connected to the box, a display chamber provided on the box, a plant model provided in the display chamber, a plurality of flashlights mounted on the plant model, the plant model connected to the inner wall of the display chamber via a plurality of connecting mechanisms, a first fixed block and a second fixed block fixedly connected to the two box plates, the first fixed block provided with a Velcro fleece surface, the second fixed block fixedly connected with a Velcro hook surface, the first fixed block and the second fixed block connected via two card mechanisms, the Velcro fleece surface connected to the two card mechanisms.

[0007] Preferably, the two box plates are rotatably connected to the teaching box via hinges.

[0008] Preferably, one of the box plates is provided with a mounting groove, a PLC control device is installed in the mounting groove, and the PLC control device is electrically connected to a plurality of flash lamps.

[0009] Preferably, the connecting mechanism includes a mounting block fixedly connected to the plant model, the inner wall of the display cavity is provided with a groove, the inner wall of the groove is fixedly connected to a first magnetic block, the mounting block is fixedly connected to a second magnetic block, the second magnetic block and the mounting block are both installed in the groove, and the second magnetic block is against the first magnetic block, and the magnetic poles of the opposite sides of the first magnetic block and the second magnetic block are opposite.

[0010] Preferably, the clamping mechanism includes a first sliding groove arranged on the first fixed block, a clamping block is slidably connected in the first sliding groove, a spring is fixedly connected between the clamping block and the first sliding groove, a clamping groove is provided on the side of the second fixed block opposite to the first fixed block, the clamping block is clamped in the clamping groove, a second sliding groove that is interconnected with the first sliding groove is penetrated by the first fixed block, a sliding block is slidably connected in the second sliding groove, and the sliding block is fixedly connected to the Velcro surface.

[0011] The present invention also provides a method for demonstrating the teaching aid for demonstrating gene mutation probability for popular science education, comprising the following steps:

[0012] (1) First, separate the Velcro surface from the Velcro hook surface, and then pull the Velcro surface and the Velcro hook surface in opposite directions. The Velcro surface moves to drive the sliding block to move, and the sliding block moves to drive the card block to move and disengage from the card slot, so that the first fixed block and the second fixed block are no longer restricted, and the two box plates are opened;

[0013] (2) Check the plant model or the flashlight and pull the plant model outward until the first magnetic block separates from the second magnetic block to confirm;

[0014] (3) Turn on the PLC control device, and the flash light switches between the green light state and the red light state;

[0015] (4) After the display is finished, close the two box plates, then pull the Velcro surface to slide the card block into the first sliding groove, then completely close the two box plates, release the Velcro surface, and under the action of the spring, the card block is inserted into the card slot, thus realizing the connection between the first fixed block and the second fixed block.

[0016] Preferably, the Velcro surface is fixedly connected to the sliding block via staples.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Turn on the PLC control device. The PLC control device uses PLC technology, that is, the flash light is always in the green light state, and after a few seconds or more than ten seconds, part of it turns red. Green represents normal cells, and red represents mutant cells. This way people can observe more clearly and the popular science effect is good.

[0019] 2. When the plant model or the flashlight needs to be repaired, the science popularization personnel can pull the plant model outward until the first magnetic block is separated from the second magnetic block, which makes it easy to repair it, convenient and quick.

[0020] 3. Separate the fleece surface of the Velcro from the hook surface of the Velcro, and then pull the fleece surface and the hook surface of the Velcro back to back. The movement of the fleece surface of the Velcro drives the sliding block to move, and the movement of the sliding block drives the card block to move and disengage from the card slot. In this way, the first fixed block and the second fixed block are no longer limited, so that the two box plates can be opened. It is simple and convenient, and the opening and closing operations are easy. At the same time, the teaching box and the box plates can protect the plant model and the PLC control device from being easily damaged.

[0021] 4. As a display device for popular science education, the present invention breaks through the limitations of traditional science communication activities based on the popular science subject's own popular science resources and tools, effectively integrates relevant popular science resources and tools, and improves the efficiency of popular science communication; it achieves the unity of professionalism and scientificity in popular science content, standardizes popular science education, and establishes and improves a device for popular science education.

[0022] In summary, the present invention has a reasonable structure and uses the change of the color of the flash light to replace the gene mutation, so that the demonstration of gene mutation is clearer, thereby making science popularization education more intuitive and effective, and can protect the plant model so that it is not easily damaged.
