Sometimes the small things that happen around you, if you think about it carefully often contain profound truth. This is what I have recently y realized by growing bean sprouts.

Since the beginning of the school year, the science teacher asked us to plant a few seeds in a small cup. I wrapped a few mung bean seeds in a wet paper towel and put them in a small cup to. Of course, I didn't forget to check it every day. Two or three days later, something magical happened, a few tender little shoots grew in the little cup, I was curious to open the paper towel and found a few snow-white roots with a few thin whiskers growing next to them. Unfortunately the root of one of the seeds broke off, and I thought it would not live, so I dug a hole and buried it.

After a few more days, the bean sprouts in the quilt grew two tiny leaves, only the stems looked noodle thin, as if weak. I thought of the broken root of the bean sprouts, walked to the yard to see, found that it not only did not die, actually grew two small leaves, looks also very strong it! I can not help but sigh: bean sprouts are too tenacious, as long as there is a glimmer of hope will continue to strive to grow, I want to learn from it ah. Seeing the bean sprouts in the soil grow so well, I bought the few slender seedlings in the quilt into the soil as well. A few days later, their stems became thicker and thicker, and the side near the soil turned red, and more leaves grew.

The beans planted in the cups were slim and weak, while the bean sprouts planted in the soil grew well, indicating that the soil has more nutrients more suitable for its growth. From this, I thought of the book is like a nutrient-rich land, we can only read more books, read good books in order to grow more. Otherwise, we will grow weak like bean sprouts in tissue paper.

CommentaryAn experience of planting bean sprouts made the author realize a truth, which can be seen that the author is a good observer and a good thinker of the child, and the article is written in a comparative way, so that we can understand the reason that people should read more.

Observation object: mung bean sprouts

Observation materials and utensils: a number of mung beans, plastic pots, water

Observation process:

The first day: I put the small mung beans in a plastic pot and added some water. After a while, I went to observe the little green beans, and found that the little green beans swelled a little.

The next day:

In the morning, I looked at the little mung beans again and found that they all absorbed water and swelled up a lot, and the skin of some of the beans had cracked, and we needed to pour out the soaking water and drench the bean sprouts with water 3 to 4 times a day. In order to keep the water, we need to cover them with a layer of gauze. In the afternoon, I saw some of the mung beans grew thin and tender buds, into a "little fat".

Day 3:

The little mung beans have grown about 1 cm of buds, and the green bean shells have detached from the bean sprouts, turning them from yesterday's "little fat man" into "big-headed son".

Day 4:

The little mung bean has turned into mung bean sprouts, the buds have grown to about 4 centimeters, the beans have become smaller, and the middle of the green leaves have grown, and from yesterday's "big head of son" into "small head of father".

Day 5:

The mung bean sprouts have been squeezed into a ball due to the small amount of space available for them to grow. I took out one of the longest bean sprouts and measured it! Total length reached 10 centimeters, the root length of 2 centimeters, the stem length of 6 centimeters, the leaves and beanstalks 2 centimeters long, if you look at it horizontally, but also very much like a small snake with a tongue! This is the time for it to become a delicacy on the table.

Observations:

In the summer, mung bean sprouts take about a week to grow, and during the growth process, the bean sprouts need plenty of water. The grown bean sprouts are divided into 4 parts: leaves, buds, stems and roots.

I once did an experiment in which two mung beans were placed in the same environment - sunlight, temperature and humidity were all the same, the only difference was that one of the mung bean boxes was filled with water and the other was not. This was an experiment in how much water affects mung beans, and it did exactly what I predicted: the watered mung bean sprouted in just a week, while the un-watered mung bean didn't change at all.

The experiment was over, but I forgot to dispose of the two mung beans and left them on the platform.

About half a month later, once, I went to the fifth floor platform to read a book, I inadvertently found that the box of mung beans without water actually have signs of germination, buds from the lower side of the mung beans grew out, tender. Although it was small, it was not easy to grow buds without water. My eyes shifted to another box of watered mung beans. After a long soak in the water, the outer coat of the mung beans had come off, and the buds, which had stopped earlier, had bent quite a bit. Now I'm interested in seeing how they change later.

Another period of time passed. During this time, I still put them on the platform, do not care, to see what new changes they have. This time, put the water in the box of mung bean sprouts have shrunk back to the roots, the body surface turned red, germination of the mouth has withered, and gradually rot, the whole mung bean like a life-threatening patient, dying.

However, the box did not put water mung beans do not want to rot like, but more efforts to bud, the body surface is more and more green, the outer skin is also tightly wrapped around the body flesh, there is no way to fall off the appearance of the buds than the previous more than double the length of about 3 to 5 centimeters. I was more and more curious.

Two weeks later, to my dismay, the mung bean without water has completed the task of sprouting, growing into a very robust mung bean sprouts, while the mung bean with water, but has completely rotted.

The same mung beans, their fate is very different. One in the adversity of the thick hair, survival, successful buds, while the other is in a favorable growth environment but to the end of the rot. The fate of the two mung beans tells us that the environment does not determine everything, the important thing is the inner quality and attitude towards things.

The day before yesterday, my mother and I saw green cabbage, tender oatmeal in the market, but they are not my favorite, my favorite is still the tender yellow bean sprouts.

I want to understand how bean sprouts grow. So we bought some mung beans. Back home, I looked carefully at the tiny mung beans, they are green like wearing green clothes, there is a white line in the middle, like holding a weapon at all times to protect themselves. I found a vacant lot on the roof, first turned the soil loose, and then put the green beans in, and then covered with soil, and finally with a pot to fill a little bit of water poured on it planted. I sat next to the side while waiting and thinking: when will they germinate?

After about 10 minutes, I couldn't wait to see the mung beans sprouting, so I looked left and right in the ground, but there was nothing in the ground but soil. I saw the mung beans did not move a little, so I said to myself: "mung beans ah mung beans, can you quickly sprout ah?" After a while, I opened my eyes again and saw that the mung beans were still not moving at all. I think they are not to sleep, so I was disappointed to go downstairs to play with others.

After two days, I woke up in the morning and eagerly ran to the roof to see. Ah! The green beans had grown out. They are curious to look at the outside world, I dance with joy and shouted "green beans finally grew out!" I slowly squatted down and observed the bean sprouts. Their heads were lowered as if to say, "I want to drink water." So I watered the bean sprouts with a sprinkler, when my mother called me below to brush my teeth and change clothes to go to school, so I reluctantly went down. As soon as I got home from school in the afternoon, I dropped my book bag and ran up to see the bean sprouts. Heh! A small green life scrambled to grow out, the bean sprouts took off the half-yellow, half-green coat, replaced with a new lime green clothes, I jumped up and down with joy. Under my careful care, the bean sprouts grow very, very fast, within a few days grew several centimeters.

Through this planting of mung beans, I understand the truth that doing anything as long as you have to pay will be rewarded.

I remember when I was in class before, Ms. Fan said that the mung bean sprouts and soybean sprouts they ate at home were made at home, and I was very interested in it and wanted to give it a try. I talked to my mom about this this morning, so she encouraged me to let me try the experiment myself.

Mom helped me find a handful of mung beans, I first wash my hands clean, and then put the mung beans into a small bowl, plus half a bowl of water, with a black plastic bag over the top, my mother said that the raw bean sprouts should be kept away from the light, or else it will grow into a green. Ready, I look forward to the germination of small mung beans.

As long as the home, I have time to look at the small mung bean germination, and sure enough in the evening, the volume of small mung beans obviously doubled, some have broken through the seed coat, revealing the white belly, mom pointed out to me to see, there are two can be seen embryonic buds. Mom said that now the temperature is very high, to change the water, every four hours to change the water. But the next day I forgot to change the water, found just sprouted mung beans hairy, I was so sad ah, my mother said that it may be the water change is not diligent or I did not wash my hands when I change the water, the bean sprouts stained with bacteria, I thought it sounds simple to do can be really difficult ah, the little bean sprouts are also strange and delicate it! But I'm not willing to give up, determined to do another test.

This time I learned the lessons of the first time, timely change of water, pay attention to health, small mung beans really live up to my hard work, really grow day by day, white stems become thicker and longer day by day, to the fourth day, I found that the bean sprouts a little bit of green, my mother said that it may be a good reason to avoid the light is not very good, but it does not affect the results of the bean sprouts are so growing.

The experiment finally succeeded, I'm very happy, I asked my mom this bean sprouts can eat, mom said of course you can, I'm really happy, the original bean sprouts is this growth ah, its vitality can be really exuberant, on the give a little bit of water, it began to struggle to grow, I also want to learn from the little mung bean, every day to absorb nutrients, and struggle to grow.

In my colorful life, many things are mostly forgotten with the passage of time, but there is one thing that makes me unforgettable.

I remember one day, the teacher assigned homework for us to write a composition on the growth of soybeans, let us first go home to plant soybeans. I'm not sure if I'm going to be able to do that. This is not a piece of cake! The first thing you need to do is to bury the soybeans in the soil and water them on time. I'm sure I'll be able to grow them very well.

Back home, I first found a big pot and a few soybeans, then the soybeans randomly scattered into the pot, and the top of the soil, watering, and waiting for them to germinate. A few days passed, I did not see a hint of soybean germination, but also still lying in the soil to sleep that. This is not intentionally and I do right? Could it be that the soybeans don't grow, or are they bad? I quickly dug them out. The soybean is still the same as before, there is not much change, still small, hard. I held them in my hands and hung my head over the beans. They rolled around in my hand as if shaking their heads and laughing at me. It was almost time for my composition class, and my beans had not even sprouted, so what should I do? At that moment, I was so anxious that tears were rolling in my eyes.

At this time, my mom came over, "What are you doing, get your hands so dirty?" "I want to plant beans, but how he did not germinate!" I said aggrieved. Mom laughed and said, "If you soak the soybeans for a while before planting them, it will germinate faster than now. Do things the right way."

Oh, so that's how it is. I went to soak the soybeans according to my mother's method. The next day as soon as school was over, I couldn't wait to observe the beans I soaked. Wow!

The beans were much fatter and shinier than before. I was under the guidance of my mother, the beans evenly spread in the soil, the top in the filling of the soil, watered the right amount of water, the beans are so planted.

In a few days, the beans sprouted, the tiny shoots look extra bright. The first thing you need to do is to get your hands dirty. I gently touch this tender green. Hairy little buds, happy, through this incident, I know a truth, do anything to have 'heart'.

One is enthusiasm, two is responsibility, three is patience!
