Abstract
Description
The present invention relates to a method for educating students on the process of digestion and absorption of a synthetic resin such as styrofoam into an organic material, and more particularly, to a method of decomposing a petroleum-inorganic compound into organic decomposition products through bacteria in a digestive organs of a specific insect And to provide an educational platform for soil pollution and its solution through learning.
Soil contamination is generally caused by livestock manure, various kinds of waste, factory wastewater, etc. Among them, contamination caused by plastic produced by fossil fuel takes a long time to recover the contamination of the soil. Is one of the problems presented in most educational materials.
In particular, styrofoam is expected to decompose soil naturally to recover pollution for about 500 years, and it is characterized by the longest period of inorganic matter that can not be decomposed by organic degradation , And these contents are usually being learned through educational grounds.
On the other hand, it is known that decomposition of styrofoam is possible by using larvae of a duck (beetle species), commonly called mealworm. In September 2015, Beihang University in China and Stanford University in USA Crake Criddle, a professor of Civil and Environmental Engineering at stanford University, said that about 100 mg of worms per day, about 34 mg to 39 mg (about one tablet) of C-Polystyrene, Half of the intermediates formed by biological degradation using Exiguobacterium were converted to carbon dioxide (CO 2), and the remainder were excreted as organic debris (C-Biomass) by fecula It is known to have published the fact in a paper (Biodegradation and Mineralization of Polystyrene by Plastic-Eating Mealworms) The.
According to the paper, the researchers also confirmed that the excreta of the wheat worm was safe enough to use as soil for growing crops, and that there was no health difference from wheat worms that had been fed on common feeds, And suggested the possibility that the larvae of the ducks could be used as environmental insects.
On the other hand, a method of biodegrading petroleum chemical compounds using insects such as cockroaches as well as wheat worms has been widely disclosed in the patent literature, and it is desirable to utilize such a platform as an educational platform, In order to provide information and learning objectives to students through a learning observation vessel that can confirm that students can directly decompose petroleum and inorganic compounds through bacterium in the intestines of insects. Should be developed.
The present invention solves the above-mentioned problems. The present invention not only teaches students a solution platform for soil pollution through biodegradation, but also provides students with educational information to think about solutions for soil pollution And to obtain an experimental training method using a styrofoam disintegration test machine.
In order to solve the above-mentioned problems, the present invention provides a method of producing a disintegration test machine (H) capable of decomposing styrofoam using a test specimen (W) ) Is provided, and a decomposition laboratory (H) for it is provided.
The above-described experimental teaching method (S) allows the students to understand the larvae larvae through the experiment preparation step (S100) for preparing the larva larvae specimen (W), and the biological information about the larva larvae specimen (W) 100).
Thereafter, the experimentally prepared sample (W) and the styrofoam (P) are contained in a separate experimental container (20) to prepare the experiment (S100) .
Thereafter, an experiment starting step (S200) in which the decomposition testing machine H provided through the experiment preparation step (S100) is stored in an experimental place where appropriate temperature and brightness are formed and then the decomposition testing machine H is left for a predetermined time Allow students to wait for the worms to disintegrate by actually eating Styrofoam.
When the larva larva specimen W waits for a sufficient time to take styrofoam (P) through the start of the experiment (S200), the students can go through an experimental observation step (S300) .
As shown in FIG. 5, styrofoam (P) after ingestion by the larva larva specimen (W) can be confirmed through an experiment observation step (S300). Then, the students can directly write the intake of styrofoam (P) in the larva larva specimen W through the
Through the process described above, students can directly observe the decomposition process of styrofoam (P) by cultivating the larvae larvae specimens (W), and it is possible not only to visually confirm the decomposition of styrofoam (P) It is possible to obtain the effect of making it possible to think about the solution solution of the soil pollution.
As described above, according to the present invention, not only the students learn the solution platform for soil pollution through biodegradation, but also the education information provides the students with a solution to solve the soil pollution directly.

Hereinafter, the present invention will be described in more detail based on the drawings and examples.
The present invention provides an experimental teaching method (S) in which students can directly produce and continuously observe a decomposition testing machine (H) capable of decomposing styrofoam using a larval larva specimen (W) Let the decomposition laboratory (H) be provided.
The experimental training method (S) described above is performed in the same order as shown in FIG. 1, and the students are allowed to go through an experimental preparation step (S100) for preparing the larva larva specimen (W) Provide biological information (100) about the larva larvae specimen (W).
The test specimen (W) used here is to be used as a mealworm beetle, a larva of a duckworm, and used as a yellow worm, a super mealworm, a wax worm, a red worm mealworm, and chili mealworm.
The above
Thereafter, the experimentally prepared sample (W) and the styrofoam (P) are contained in a separate experimental container (20) to prepare the experiment (S100) .

Thereafter, an experiment starting step (S200) in which the decomposition testing machine H provided through the experiment preparation step (S100) is stored in an experimental place where appropriate temperature and brightness are formed and then the decomposition testing machine H is left for a predetermined time Allow students to wait for the worms to disintegrate by actually eating Styrofoam.
In this case, it is preferable to store the disassembly test machine (H) in an experimental place of 21 to 27 degrees Celsius. The above temperature condition is the temperature at which the metabolic activity of the wheat worm is most active, thereby promoting the biodegradation action of the styrofoam You can do it.
On the other hand, there is no known precise information about the brightness of the test site. However, since the mills can be actively operated in a normal range of 100 lux or 250 lux, which is the normal brightness of a school or a library, .
When the larva larva specimen W waits for a sufficient time to take styrofoam (P) through the start of the experiment (S200), the students can go through an experimental observation step (S300) . At this time, since it takes 6 to 24 hours from the start of the experiment (S200) to the time when the test specimen (W) can successfully excrete the excreta after taking the styrofoam (P) successfully, S200), and then the process can be performed in the experiment observation step (S300) after 6 to 24 hours.
As shown in FIG. 5, styrofoam (P) after ingestion by the larva larva specimen (W) can be confirmed through an experiment observation step (S300). Then, the students can directly write the intake of styrofoam (P) in the larva larva specimen W through the
