Today, in order to cultivate our observation ability, the teacher arranged for us to keep a diary and observe the growth process of bean sprouts. In the evening, my mother and I caught a handful of soybeans and put them in a transparent glass. Then we poured some water into the glass and soaked the soybeans in the water. So we started the first day of the experiment. I found that soybeans look oval, light yellow in color, and have a black mouth on one side, which looks like lips. When the water is poured in, it seems to be drinking water.

It will be sunny on Tuesday, May 25th, 2065 at 438+00.

I went to see my soybean experiment together this morning, and found that the soybean was swollen and bulging, which was two or three times larger than the original, but the bean sprouts had not yet grown. Mom said it would take some time to plant bean sprouts. In the evening, mother pours out the water, then wets it with a piece of cloth and covers it on the cup. I don't understand, and my mother told me that soybeans can't be soaked in water all the time, as long as they are soaked for one day, otherwise they will rot, but they must keep a certain humidity, so cover the cup with a wet cloth to prevent the water from evaporating quickly.

Wednesday, May 26th, 2065, 438+00 sunny.

This morning, I saw soybeans again. I was surprised to find that sharp, short and tender white buds appeared on the head of soybean, just like the horns on the head, which was very cute. Mother sprinkled a little water on it to keep it moist. When I came back from school in the afternoon, I saw that the bean sprouts had grown a little taller. Grandma asked, "How long are bean sprouts?" I quickly took a ruler and measured it, about 2mm. But some haven't grown yet.

20 10 it will be cloudy on Thursday, May 27th.

This morning, I found more soybeans sprouting. The earliest bean sprouts grew so fast, but their lengths were different, and most of them were curved. At night, when I opened the cloth covering the beans, a pungent smell came to my face. Why do soybean sprouts stink? My mother asked me to observe carefully: it turned out that some beans were rotten, and that was the bad smell they gave off. So we picked out bad soybeans and bad bean sprouts. I picked two of the longest bean sprouts and measured them, and they were actually 28 mm long. I saw that the root part of the bud connected with soybean was light green, the tip part was a little light red, and the middle part of the bud was the thickest and white. I found that the longer the bud, the thicker it is. There are many peeled bean skins in the cup. I think the bean sprouts are undressing beside me. It may be too hot!

Friday, May 28th, drizzle 20 10

Today, I saw that the buds of small bean sprouts are relatively long. Because bean sprouts are crooked, they can only be estimated to be 50 mm I am surprised by the growth speed of bean sprouts! The long-sprouted beans have begun to turn green, which is very similar to the bean sprouts we usually eat. Besides, soybeans are getting bigger. Mom said: In a day or two, bean sprouts will grow, a beard will grow on the bud of bean sprouts, and some soybean "lips" will crack. I am looking forward to it.

Observation diary

Soaked soybean

Today, when I came home from school, I took some soybeans, put them in a small bowl and poured some cold water into them. Do you know what I do? Yes, I want to soak soybeans! Dad told me that it would take several hours for soybeans to change. I kept a close eye on the soybean's every move, as if afraid that it would run away. After just over an hour, I couldn't wait to investigate. Who knows, it is so heavy that it stays where it is. I couldn't help being anxious, and secretly said to myself, "Little soybean, change it quickly, and don't make me impatient!" " "But little Dai Dou unmoved, as if angry with me, still go its own way. After more than three hours, thankfully, the small soybeans finally softened, and with a little slight change, the color of the rice grains also faded. " You finally understand my trick. "I have a little secret happiness.

Go home as soon as school is over today, and change the water for the small soybean quickly to avoid its depression. At this time, I found that the small soybean was fat and bulging. "Look how greedy you are!" I said to it humorously. The small soybean seems to be hot, so it lifts its yellow coat and shows its white fat belly, just like a general. There is a crack in its body, as if it were grinning at me! I also smile.

Today, I found that almost all the skins of small soybeans have been peeled off. I just wanted to help it peel off the skin, but I held back when I thought that my father said that I couldn't eat hot tofu in a hurry. The taste of small soybeans has not changed, but it is still slightly sweet. The thought of peeling small soybeans fills my heart with joy, as if a bear had eaten honey.

65438+100 on October 26th

Today, in order to cultivate our observation ability, the teacher assigned a special assignment: Let's go home and soak soybeans. When I got home, I grabbed a handful of soybeans, put them in a cup, added some water, and pinched them with my hands. Soybeans are hard. After a while, some soybeans became a little bigger, and the skin of some soybeans was wrinkled.

I observed here today. This soybean is really fun!

65438+100 on October 27th

Continue to observe my soybeans today. It was found that some beans exploded, some beans became bigger, and the big ones were two to three times smaller. Beans under water are bigger and wetter than those on water, and beans on water are smaller and drier than those under water.

This soybean is really interesting. It will get bigger and smaller.

65438+100 on October 28th

Today, I observed my soybean again. It was found that the soybeans under water were suppressed by the soybeans on the water surface, and there was no fresh air, so they did not germinate. The soybean above the water was too dry to germinate, but the soybean in the middle had both moisture and enough oxygen, so some of it germinated, and the bud was so cute: the pale yellow bud protruded from the soybean, just like the soybean had teeth, and the bud was a little curved, so cute! Unfortunately, several buds were crushed. My mother said that soybeans can't be pressed like this, and they have to be spread out to germinate. So we help the soybeans move, move them from cups to pots, and then spread them evenly.

I think: in this way, there should be more buds tomorrow!

65438+29 00 10 month

Today, as expected, more beans germinated. I saw that the root part of the bud connected with soybean was light green, the tip part was a little light red, and the middle part of the bud was the thickest and white. I found that the longer the buds grew, the thicker they became, and some buds even took off their tops. It may be too hot!

101October 30th

Today, I saw that the sprouts of Baby Bean have grown. The long-sprouted beans have begun to turn green, which is very similar to the bean sprouts we usually eat. Besides, soybeans are getting bigger.

65438+1October 3 1

Today, when I opened the cloth wrapped in beans, a pungent smell came to my face. Why do soybean sprouts stink? My mother asked me to observe carefully: it turned out that some beans were rotten, and that was the bad smell they gave off. There are many peeled bean skins in the basin. I looked at it carefully. Oh, it was broken by MengMeng. I also found that more beans turned green. What happened? I went to check the information, only to know that when soybeans germinate, cotyledons provide nutrients. After the cotyledons germinate, the sunlight gradually produces chlorophyll, and the cotyledons first produce photosynthesis. In this way, bean sprouts can be autotrophic through photosynthesis, so they will turn green after germination.

Today, I smelled the beans, which were very sour. Small beans seem to have taken an "acid bath" and still have a little taste. I touched the skin of a small soybean, tender as tofu, and it will break when I pinch it. Some small soybeans are cracked like two small semicircles. It's a pity that my father fell down, because my little soybean filled my home with sour taste. I'm really sad!

This little soybean is really interesting!

5. The fourth grade composition observed that soybean was cloudy on Friday September, 200918.

Today, the teacher assigned us a special homework, which you wouldn't expect, and that is soaking beans.

At noon today, I took a glass of water and a handful of beans according to the teacher's instructions. I held the beans in my hand, rolled them and rubbed them. I feel that there is a teacher hidden in the beans, which is very comfortable. I smelled those beans again, and they smelled like fish. I took out a soybean and touched it. Very smooth, like a girl's face, with a black spot on it, like a girl's smiling mouth. When I put soybeans into the water, a little bubble appeared on the water from time to time, as if to welcome them. This is really a magical glass of water. The girl who just went in for a few minutes turned into a wrinkled grandmother. I can't believe my eyes. I took out a soybean and looked at it. It's really wrinkled Probably when I went to school in the afternoon, the soybeans became a little bigger.

I went home immediately after school in the evening. When I got home, I couldn't even bring my schoolbag, so I couldn't wait to see the soybeans. "Oh, my God," I couldn't help crying. I don't know how many times the soybean is bigger than before, but it has a lot less water. These soybeans are now as smooth as freshly baked steamed bread. The water turned yellow and fishy. Tonight I changed the water according to the way the teacher taught us, and waited for the next day.

September 2009 19 Saturday light rain

Today, I am looking forward to making soybeans germinate quickly. It seems that God is as anxious as I thought, and I cried.

I went to observe soybeans at night and found that some soybeans had begun to shed their skins. After the skin faded, the black spots growing next to the soybeans disappeared. Now the soybean end has obviously increased. I took out another soybean and pinched it. Although it can't be broken, it is much softer than the original. With a little effort, soybeans emerged from that skin. I found a small bud on the swollen hair of soybean. The bud is pale yellow, and it clings to the soybean like a baby nestled in its mother's arms. I smell the beans, which are very similar to the thick soybean milk just made. I took a bite of the beans, which were as crisp as fried potatoes. When the soybeans sparkled in the light, I found a little oil on the water. I think, isn't there soybean oil in the supermarket? Maybe the beans have been soaked for too long, so they have come out!

I changed the water for soybeans again, expecting soybeans to surprise me tomorrow.

On Sunday, September 20th, 2009, it was raining lightly.

I finally waited until tonight. What surprises will soybeans bring me now?

I uncovered the cloth that had been covered with soybeans for a day, and found that soybeans have not changed much today, but more soybeans have begun to shed their skins, and the roots of some small buds have drilled through that skin. I found that the skin was thick, but soybeans without that skin were light. It seems that soybeans are so yellow because of this skin! I thought: Why do people call them soybeans? It should be called soybean skin. I took out the beans peeled yesterday. As soon as I squeezed it, the beans immediately turned into two petals. Hey, why don't you smell beans today? Yes, I used to smell beans when I stood by. Why not today? I leaned over and smelled it, and the beans smelled of soybean milk. At the same time, I thought of another problem. Why have beans been growing for the last two days, especially on Friday afternoon? I looked up some books about plants. It turns out that soybeans absorb water as soon as they are put into water to meet their own growth needs.

Today, I washed the soybeans and covered them with a cloth. Let's see what happens tomorrow.

It was sunny on Monday, September 2, 2009/KLOC-0.

When I came home from school this afternoon, as soon as my schoolbag was put away, I quickly went to see how my bean sprouts were. When I opened the cloth covered with bean sprouts, I saw that the bean sprouts had grown up obviously, but the lengths were different, and most of them were curved. Some bean sprouts are white and fat, like an Arabic numeral "9" and a happy note. Some are thin and small, completely "stunted" and ugly. I got close to the plate and smelled it. I smelled a faint fishy smell. I asked my mother what was going on. My mother said, "Soybean sprouts need air to grow. If you soak in water for a long time, it will stink if you are not exposed to the air. The smell you just smelled came from rotten soybeans that haven't germinated yet. " After listening to my mother's words, I went to pick out the rotten sprouted beans and throw them down, leaving some stout bean sprouts for me to continue to observe. But there's not much left.

I changed the water for the beans and covered them with wet cloth, looking forward to the changes of soybean sprouts tomorrow.

Tuesday, September 22nd, 2009 is fine.

As soon as I got home this evening, I was surprised to find that bean sprouts had grown.

The roots of bean sprouts are light yellow, and the thinner they are, the closer they are to watercress. The roots feel smooth and smooth. I've never seen such a root. It seems that it has just been oiled. When I squeezed the root, the water immediately flowed out of it. Oh! I didn't expect this one to be so thick and slippery because it is full of water! Look at douban again. The bottom is white, with a little light green in the middle and yellow on the top. This bean sprout coat is really nice. Now bean sprouts have almost no taste, only a faint fragrance. I took a ruler and measured it. It is five centimeters. I can't believe that bean sprouts grow so fast. Mom looked at it and said; "Soybean sprouts will not change much after they grow like this. This is similar to the bean sprouts we usually eat.

Although there is not much left, my mother promised to fry me at noon tomorrow. I'm really looking forward to the feeling of planting soybean sprouts!

6. After the Chinese class on the fourth grade soybean observation diary, the teacher asked us to go home and plant a plant and observe its growth process. As soon as I got home, I asked my grandmother for some soybeans and buried them carefully in the soil. My grandmother told me that it needs enough water to grow soybeans. After I planted the soybeans, I began to water them. A few days have passed and nothing has changed.

A week later, I found that the soil where soybeans were planted was higher than other places. When I gently turned over the soil, it turned out that the soybean had a pale yellow bud. A few days after it was unearthed, the bud turned green again. Two days later, the light yellow one is small? Several leaves have grown in the garden, which are light green and very lovely. I want to see it every day.

As the days passed, the buds grew taller and taller. I put some sticks in the soil, and the vines of soybeans climbed up along the sticks. Soon, they climbed to the top of the branch.

After half a month, pods grew on the vines, and there was a thin layer of hair on the pods, which felt soft and interesting. The pods also gradually deepened from the light green at the beginning. Grandma told me this is my favorite edamame. I watched it grow up little by little, and my heart was full of joy. When the pods turn into Huang Shi, you can pick beans. I plucked the pods from the vine. Hey, this is a big gain. There are at least two soybeans in a pod. I always * * harvest 10 pods and more than 20 soybeans!

Through this bean planting, I know that as long as I work hard, I will definitely get something.

7. The fourth grade 400 observed soybean composition science teacher asked us to grow a plant ourselves and observe it. I chose to grow soybeans.

First find a transparent plastic cup, put it in the soil, put soybeans on the wall of the cup, then cover it with a layer of soil and pour water on it. After a few days, I was a little impatient. Why didn't this soybean germinate? I asked my mother with questions. My mother said, "You have to drill holes under the soybean cup to let the water run away, and you have to put it in a sunny place." Did you do it? " I shook my head and quickly replanted it according to my mother's words. However, in a few days, white roots grew out of soybeans, and with the passage of time, the roots gradually increased.

I found that wherever the beans went, Reagan fell. Soon after, the shell swelled and the stem grew out, but the shell disappeared. I think it may have turned into fertilizer. The color of the stem is green, standing on the soil like a guard. There are also a pair of cotyledons on the stem, which are green. According to the science teacher, cotyledons are composed of two soybean petals. I am very happy that real leaves will grow in a few days. I watered the water on time as grandpa said, and there were really many leaves. Slowly, I found that the leaves turned yellow and didn't grow fast enough. The original cup is not big enough for nutritional supplement. Grandpa and I moved the bean seedlings to a bigger flowerpot and fertilized them. Gradually, the leaves turn green and tender.

Looking at it, I thought, if I could eat the fruit I planted, how happy it would be! I wish my own soybeans would grow faster.

8.300-word composition Five observation diaries of soaking beans for four years 1 observation diary soaking beans for 300 words.

Today, the teacher arranged an observation diary for us, and you went home to do an experiment of soaking beans. "。 I thought to myself: I can soak beans.

When I got home, I said to my mother, "The teacher writes an observation diary for us and needs to soak some beans. Would you please bring me some beans? " Mother immediately took out a big bowl and poured a spoonful of beans into the bowl. There are red beans, soybeans and mung beans here. They are lying in a bowl, squeezing each other, and the color is beautiful.

At first, beans didn't seem to change much. After a few hours, the beans swelled, several times larger than before.

After a day or two, in my careful care and anxious waiting, beans really didn't let me down. It gradually becomes full, with a little filament and white buds growing from the middle, just like the tentacles of a snail.

Unconsciously, the bean sprouts have grown into a small forest, and everyone seems to be showing off: "Look, how tall I am …".

The so-called "no pains, no gains" is completely correct. "

The second observation diary soaked beans 300 words

The first day: I came home from school in the afternoon, picked up a cup, filled it with water, took out several bean babies and put them down one by one. Seeing a cute bean bag is like getting drunk and stumbling down. I'm thinking to myself: What will Baby Bean look like tomorrow? Will it peel off?

The next day: go home from school at noon. I am not in a hurry to do my homework. I ran to the kitchen first to see what would happen to adzuki. When I entered the kitchen, I found that the doll beans were getting fatter and more tender! It began to peel, but the adzuki beans didn't germinate. After a while, the skin of the doll bean fell off! One, two, three, four ... At this time, the water in the quilt gradually turned gray, but a little white. I changed the water for the doll beans, and the sewage in the past has now turned into clear water. I think: doll beans should be comfortable! What should Baby Bean look like tomorrow? Will it sprout?

The third day: after school in the afternoon, after lunch, I saw that all the babies began to turn black and a little bud appeared on the tip of the bean. At this time, I suddenly found that everyone reported wrinkles, just like grandma's wrinkles. But the water in the cup turned into sewage again, and I changed the water again. This is amazing!

Day 4: After my careful care. Adzuki bean is getting bigger and bigger. Hehe, I finally learned to soak beans. Through careful observation and hands-on, I experienced the process of soaking beans. How interesting!

The third observation diary soaked beans 300 words

Today, in Chinese class, Mr. Wang assigned a special assignment, asking us to go home and observe soaking beans.

I came home happily, happily brought a small bowl, put some beans in it, poured some water, flooded the beans and covered them with white gauze.

On the first day, I opened the gauze and looked at it. I found that the color of mung beans became lighter. Some of them float on it like swimmers, while others sink underwater like divers. The next day, I suddenly saw a little green on the gauze. I looked at the beans again. The beans took off their coats to reveal their delicate bodies. Beans are fat and big, like a white and tender fat doll. On the third day, the bean's "belly" cracked a small crack and stretched out a short beard, like the short tail of a tadpole. There are two small leaves on the bean, which are tender and lovely. On the fourth day, the little bean finished drinking water, so I quickly added some more water. After a few days, adzuki bean became a little purple and its beard grew like a toothpick.

This is the interesting bubble bean.
