Meet you, some chemistry!

Chemistry teacher "exclusive formula" ignites "hot" final comment

  When going to school, students look forward to the two things that are most anxious. One is to know the test scores, and the other is to see the teacher's comments.

In the hearts of students, the teacher's comments are very heavy, and a praise comment can make people happy for a long time.

  At the end of this semester, teacher Xue Lei from the third grade (19) of Suzhou Lida Middle School combined his teaching knowledge and used different chemical equations to design an ingenious final comment for each student in the class.

Today, we are going to read this chemical equation that "ignited" teachers and students.

The chemical equation "ignites" the fiery final comment

  On January 28, 2021, the last day of the semester, every student in the third grade (19) class of Suzhou Lida Middle School received the final comment of the "Chemical Equation" carefully designed and carefully copied by the head teacher Xue Lei.

  These comments use chemical equations as the "introduction", which is not only a "fancy" appreciation for the different personality characteristics of each student, but also full of the teacher's high expectations for the students.

Iron, if the particles are smaller, the burning phenomenon will be more intense. When you reach the nanometer level, iron powder can also spontaneously combust in the air.

Therefore, everything is inseparable from precision and meticulousness. As long as you work hard to the extreme, the rewards behind the effort will be natural.

  He Jiahao, a student in the third grade (19) of Suzhou Lida Middle School: During a chemistry exam, I was going to fill in the options on the answer sheet. Because of the tight time, I missed an option, which led to the next dozen questions. In the wrong position, the final result is not too optimistic.

The teacher affirmed my efforts and hoped that I would pay more attention to some minor aspects.

Pure hydrogen can burn quietly after being ignited, while impure hydrogen will easily explode violently when it encounters Mars.

And just like your mentality, if you have no distracting thoughts, you can easily sink into thinking and immerse yourself in the joy of learning, then make your study life more pure and stable.

  Zhao Hang, a student in the third grade (19) of Suzhou Lida Middle School: Because I usually have a bad temper, I am a "little hot", and I am not a particularly obedient classmate in the class. Then Teacher Xue hopes to write this comment for me It can settle down even more.

In high-temperature decomposition, we need 3,000 degrees Celsius to decompose to obtain aluminum, but by changing the method, we can electrolyze aluminum at only 1,000 degrees Celsius.

Therefore, in addition to perseverance, we need to use appropriate methods when it seems impossible to overcome difficulties.

  Wang Chongyu, a student from Class 19 of Junior High School of Suzhou Lida Middle School: In the face of difficulties, sometimes I will just blindly smash, and sometimes it will not solve the problem.

So Teacher Xue gave me this equation to tell me that we added cryolite to electrolytic alumina, which can make the reaction easier. I also need to choose a suitable method to solve this problem with higher efficiency. .

So I think this comment is quite useful to me.

  It was the first time for the students to receive such unique comments in 9 years of school. Everyone shared them with each other with great interest, and laughter came and went one after another in the classroom.

These "Chemical Equations" comments were posted on the Internet by the parents of the students. Netizens expressed their envy and love for the "other teachers". One netizen concluded: "It must be a very careful company to write such a carefully. Comments!"

The teacher is the match that ignites children's hope

  Xue Lei, the author of "Chemical Equation Comment", has been working for 19 years this year, and he has been a class teacher for 14 years. However, he wrote "Chemical Equation Comment" for students or "the big girl sitting in a sedan chair-the first time." .

In early 2021, why did Teacher Xue Lei decide to bother to do such a thing?

  Xue Lei, head teacher of the third grade (19) of Suzhou Lida Middle School: I started this year from the first grade, that is, they came into contact with me when they graduated from primary school, so the feelings are very deep.

  Teacher Xue said that he has been with the students in this class for two and a half years, and he has a full understanding of each child, understands their hobbies, emotions, sorrows and joys. Only in this way can he create for each child. Give an appropriate "chemical equation comment".

  At the beginning of January this year, Mr. Xue started to create.

He wrote nearly 10 comments in the first two days, feeling free and easy.

On the third day, difficulties emerged.

  Xue Lei, the head teacher of the third grade (19) of Suzhou Lida Middle School: I entered the first bottleneck period when I wrote more than ten, and then I wanted to encourage students to write.

During the class meeting, I said that I wrote a few, and everyone came to help me germinate. The students found that it was very easy to listen to, but the students found it difficult to write!

  Teacher Xue launched several rounds of "brainstorming" and finally received 4 comments designed by students.

A pair of inseparable girls use chemical elements to depict each other, which is very innovative.

What is lithium?

The metal with the smallest density, just like the small and exquisite you, does not cover the eyes of the floating clouds, but is only on the highest level.

With a little change, the lively "2-1 structure" can also become a stable structure. You already have a hardworking, conscientious and conscious you, and a little change can turn it into a driving force for wisdom.

  Li Jiayin, a student from Class 19 (Junior 3) of Suzhou Lida Middle School: She wrote Li, because I happened to be Li.

Lithium is the metal with the lowest density, just like I am unknown in class and relatively quiet, but if there is oxygen, it will shine brightly.

She may also hope that I can show my true self in front of more people.

  With the help of the students, Mr. Xue completed 20 comments, and he found it more difficult at this time.

  Xue Lei, the head teacher of the third grade (19) of Suzhou Lida Middle School: I follow my student number, one by one, with girls in the front and boys in the back.

I am writing, and I have written 20, and I told the students that my girl has finished writing, and I said that I have exhausted my talents, and I can't write it anymore.

Then the boys immediately said, "Teacher, you can't be unfair, we boys too!"

That line, I continue to "dig holes", continue to write down!

  Teacher Xue used almost all the rest time to continue his "creative journey".

The chemical equations of junior high school had been in his mind several times, and there was really no suitable one. One night, he had a sudden inspiration and started to use some simple chemical equations of high school to enrich his creative materials.

After another week, all 45 comments of Teacher Xue were finally completed.

  Xue Lei, the class teacher of Junior Three (19) of Suzhou Lida Middle School: Happy and proud!

I also want to rush out and tell the students immediately, I've done this!

  After two and a half years of getting along day and night, the deep feelings between Teacher Xue and the students were finally integrated into these 45 "chemical equations".

Among them, the work that Mr. Xue is most satisfied with is an equation about magnesium combustion, which is also an expression of his aspirations.

Teaches like spring breeze

The magnesium belt burns.

Just as the gray-black magnesium oxide conceals the silvery white of the magnesium band, your enthusiastic character is covered by the protective film, but as long as you want, the dazzling fireworks blooming in the dark night are magnificent and the pictures in the sky are inseparable. Open your slender figure, and the teacher is willing to be the match that ignites you.

  Anqi Feng, a student in Class 19 of Junior High School of Suzhou Lida Middle School: Although I am a propaganda committee member, I am actually not very outgoing. I am also more reserved. I don’t dare to ask the teacher about learning problems, just like a magnesium belt. It is like being wrapped by an oxide film in oxygen. The teacher hopes that I will abandon the oxide film like a magnesium belt when it is burning, and bloom with a dazzling light.

The magnificent aerial pictures may also mean that my posters are better.

  The teacher is the match that ignites children's hope!

Mr. Xue's 45 "special" comments and the enthusiasm melted in them light up the firm belief in each student's heart and emit a brilliant youthful light!
