When I was in the third grade, I started taking chemistry classes. Maybe my brother loves to play tricks since he was a child, influenced by him, and likes to do all kinds of experiments. When I was in elementary school, I knew that vinegar and baking soda would produce carbon dioxide, and potassium permanganate heating would release oxygen.

Therefore, I am full of expectation that this course will be held soon, and even asked my sister to find out her previous junior high school chemistry textbook and get a sneak peek.

For a boy, physics and chemistry seem to open a colorful magic door, which is a world full of fantasy and magic.

Because my parents are teachers, my family naturally lives in the teachers' family area of the county, so my neighbors are all kinds of teachers. I remember a teacher Liu from Shuai Shuai who likes playing basketball very much. Sometimes our teacher's children have played with him several times.

He probably knows that my parents like to call me every time they play ball. In fact, I am not good at it, mainly because I am diligent. Every time the ball ran away, I picked it up and never had a conflict with others. That's probably why he likes me.

At the end of the summer vacation, one day after playing ball, he and I told me on our way back that he might take our chemistry class next semester.

I jumped up happily and asked him, "Teacher Liu, do you really want to take our chemistry class?" "Ha ha, it seems that you are looking forward to my replacement!" I laughed and said, "Of course, doing chemical experiments is very dangerous! I don't want to find a female teacher to do experiments for us! "

Teacher Liu put his arm around my shoulder and said, "smelly boy, I'm not afraid of doing experiments and suddenly exploding!" " "

I glanced at him and said wryly, "With your head, it's raining all over Mao Mao!"

Teacher Liu lit up his biceps and smiled and said to me, "Your father said that if you don't listen, I can repair you."

I also smiled and said, "I will be obedient. I will hide in the last row of our class when you do the experiment. "

Teacher Liu said, "Nice try, I'll let you be the representative of chemistry class!" " ! Help me with my experiment! "

I was depressed. Why do teachers always like me as a class representative? The general class representatives are all girls!

Teacher Liu looked at me disheartened and said, "I'm afraid, well, as long as you are the first in chemistry, I'll give you a basketball." The class representative is also appointed by the class teacher, and the boys are not counted! " Ha ha! "

I was relieved and went home with him happily!

After school started, our chemistry teacher proved to be Miss Liu!

I saw him in class and he winked at me. Of course, his appearance also made our classmates shine at the moment. Why is this chemistry teacher so stylish? He is like a PE teacher.

Sure enough, the chemistry class representative was appointed by the class teacher, so that the Chinese class representative, a fragile girl, also served as the chemistry class representative. Looking at her fragile appearance, I'm a little worried about Miss Liu.

At the end of each class, Mr. Liu asked me to help, which made the chemistry class representative very happy. Apart from sending and receiving homework, she didn't do her duty as a representative of chemistry class at all.

On the other hand, I like this job very much. I move many bottles and cans with a big plate at a time, and sometimes I ask several male students to move another plate of equipment.

I remember clearly that in the oxygen class, the teacher had to heat potassium permanganate to make oxygen. I volunteered as an assistant. The students in the first row still dare not flinch. I looked at it and secretly smiled. I don't have eight ounces of potassium permanganate to play with, so there's nothing to be afraid of.

With my infinite love for chemistry, I won the first place in the mid-term exam, the first place in the whole grade in the final exam and the first place in the senior high school entrance exam. Teacher Liu also kept his promise and really gave me a basketball.

Later, after graduating from junior high school, every time I saw him, I was always full of praise. I often tell people that I am the first student he has ever seen who consciously memorizes the periodic table of elements! He likes me very much!

Later, I went to college and got the best grades in chemistry. I think this is inseparable from the solid foundation that Teacher Liu laid for my junior high school. The most important thing is that he cultivated my interest in chemistry. If you like doing this, no matter how hard you work, you will feel a kind of enjoyment.

Today, although I have not engaged in any work related to chemistry, it seems that the spirit of exploring scientific knowledge has quietly planted seeds at that time.
