Time flies, and the day is coming to an end. I think everyone has learned a lot of new knowledge. Let's take action and write a diary at once. But how to keep a diary to shine? The following is a sample essay (selected 17) on the observation diary of fourth-grade bean sprouts, which I compiled for you. Welcome to share.

Observation diary of fourth-grade bean sprouts11October 15 It was rainy on Thursday.

Dad bought half a catty of mung beans and told me to plant mung bean sprouts. After watching the teaching video, I followed suit.

I poured mung bean sprouts into a stainless steel basin, washed them with clear water, and then soaked them in clear water for 24 hours. At this time, mung beans are turquoise, and the particles are solid and full, like tiny emeralds. 24 hours later, I came to the mung bean with a curious heart. Wow! Mung beans have changed a lot. Mung beans, which used to be strong, have now become soft and swollen. Some of them also showed their white bellies, which were white and tender, so lovely.

I watered them and hoped that they would grow up quickly.

10 19 rainy Sunday

It's the third day of planting mung beans, and mung beans look different every day. I excitedly went to the kitchen to see what changes they had made.

Open the towel and look, "Wow!" I saw all the mung beans, and all the fruits were separated from the shell. One or two yellow sharp leaves grow between the douban, which is the tender leaves of mung bean sprouts. Under the watercress, a white tender stem of about one centimeter grows, which feels soft and fragile. My father told me to be careful not to break it, otherwise this mung bean would be wasted. I continued to observe mung bean sprouts carefully, and found that a smaller root grew under the stem. Compared with the stem, it was thin and long, just like the gray beard of grandpa. I thought to myself, the vitality of these white fine roots is really strong, and it is incredible that they should penetrate through the thin seam of gauze and plunge into the roots to absorb the water in the basin. I sprinkled water evenly on these elves with a watering can, and suddenly, the fragrance of bean sprouts floated out of the basket. I hope they grow up quickly!

Observation diary of planting bean sprouts in the fourth grade 2 I planted some mung bean sprouts at home.

Since I planted them, I have a concern in my heart. The first thing I do when I get up every day is to see them. On the first day, I didn't see anything, and I was a little disappointed. Early the next morning, I was still dreaming a beautiful dream. My sister pulled me out of bed, pulled me to the bean sprouts and looked at me with a smile. I quickly looked into the plate and jumped three feet high with joy. Ah, the bean sprouts I planted have grown. Although it is only a small thin bean sprout, it looks very fragile. I feel that as long as my hand touches it, the bean sprout will break, but my heart is as sweet as honey! Slowly, the young bean sprouts grow green leaves. After a few days, the small bean sprouts grow taller and the leaves are greener! After a period of time, the adzuki bean bud became very tall, its leaves changed from turquoise to dark green, and the stems in the soil had grown 15 cm, and the height was 16 cm. Mom said, bean sprouts can be eaten. I carefully pulled up the bean sprouts, washed them and asked my mother to fry them for me. Eating the fruits of my own labor, my heart is full of sweetness.

I think this bean sprout is really not white, it makes me feel the joy of labor!

Observation diary of planting bean sprouts in the fourth grade 3 Before school on May 18th, the math teacher assigned an assignment: plant bean sprouts and record the growth of bean sprouts every day. As soon as I got home and put down my schoolbag, I got to work.

I want to plant soybean sprouts. According to the procedure, I should soak the soybeans in water for one day, pour out the water the next day, and then cover them with wet gauze. I started the first step. After soaking in water, I went to do my homework. Somehow, when I was doing my homework, others couldn't bother me, but today no one bothered me, but my heart itched. I always ran out to see if the bud had grown. I watched it eight or nine times in the evening. It's almost nine o'clock, and I've started to urge me to go to bed. I can't sleep in bed, tossing and turning, just like ants in a hot nest. I really want to pull out the seedlings and encourage them.

The next day, before dawn, I went to see it. Why didn't it sprout? Is there something wrong with the beans? Although I said that it didn't germinate so soon, I was still dubious. School is coming soon, and my mind is focused on bean sprouts again. Sitting in the classroom, I feel uncomfortable all over, as if there is a small ant crawling in my heart. I am so anxious!

Finally, after school, I flew to the balcony. When I saw it, nothing happened. I stared at it hard, but nothing happened! I was a little discouraged and went to my room to do my homework. This evening, I didn't go to see it again, and it was boring. Let it go.

On the third day, after school, I was preparing to do my homework. My father asked me to look at the bean sprouts on the balcony. I wanted to look at them, but I had no hope anyway. When I opened the gauze, I was so excited that I almost jumped up. White and tender buds grew out, which was eight millimeters long. I squatted on the balcony for a long time and almost forgot my homework. My father's words reminded me.

In the next few days, the bean sprouts grew taller and taller, and I seemed to be more and more proud, because I successfully planted bean sprouts, and I was very proud.

I bought some mung beans and planted them in newspapers with moisture. I think you must be asking why you planted them in newspapers instead of in the soil. This is because if such a small mung bean with no resistance is planted in the soil, it may be swallowed up by those greedy and despicable caterpillars. Planting it in the newspaper will not only protect the mung bean, but also make it grow up as soon as possible.

I sprinkled small mung beans first, thinking: be careful! Watch out! Don't break these lovely mung bean babies, they are my hope, my darling! I planted one or two and added a little newspaper. I finally planted all the mung beans with great difficulty. But when I finished planting mung beans, I saw it, yeah! My mung beans are high and low, and there are nutrients at the bottom, but they can't be absorbed at all at the top! I thought about it, hey, I thought of a good idea when I slapped my thigh. Wouldn't it be better if I smoked some newspapers? I happily smoked some newspapers, took the mung beans off them, and let them go, just right!

Ah! I looked at the newly planted mung bean, expecting it to take root and sprout quickly ...

Observation diary of bean sprouts in the fourth grade 5 The longest mung bean sprouts in my family are 28 cm, and at least 1 1 cm. The growth process of my mung bean sprouts is a little different. If you want to listen, just listen carefully.

That day, my mother bought a bag of mung beans. When I saw it, my eyes lit up, haha! I know what to observe! I ran to my mother in front of me: "Mom, mom, can you give me some mung beans you just bought?" Sure, it's just for you.

I quickly ran to the room, picked up a plastic cup and put some water on it. I picked up mung beans and carefully selected them to see if they were firm, full and good in color. The mung beans I picked looked pleasing to the eye like jade, and these mung beans were honored on the list.

At night, the little mung bean is like eating a lot of things, and suddenly it has changed from a "skinny" to a "fat". I look at it every day and look forward to it every day, but there is no movement for two days in a row. Just when I was disappointed, I actually saw a small bud coming out after school that day. In the following days, the mung bean grew longer every day, so tall and straight, so strong, I didn't expect a small mung bean to be so strong.

I reviewed the feelings of this observation. First, I can't be impatient. Things change in a regular way. Second, small things have great energy. It was an interesting and rewarding observation.

One day, I went to buy some mung beans, put them in a small bottle with water, and then put a piece of plastic wrap on it.

Next, I kept observing whether the mung beans in the bottle had changed. After 2 hours, mung beans still haven't changed much, but they have increased a little. I think: mung bean, mung bean, sprout quickly. The next day, I saw the mung bean in the bottle grow some white and tender buds like a tail, break through the coat and get out to breathe fresh air. Mung beans let me see its strong vitality. On the third day, the bean sprout slowly grew two white and green leaves, and the mung bean finally sprouted. On the fourth day, when I went to change the water, I found that the bean sprouts grew half as high as the bottle, and the leaves became bigger, and the leaves changed from white to tender green. Oh, the leaves grew up. On the fifth day, the leaves changed from tender green to yellow. The bean sprouts grew 4 or 5 centimeters taller, and some mung bean skins were stuck on the leaves. The adults said, "You can eat." Mung beans grow so fast.

From the observation, it is found that the growth process of mung beans into bean sprouts is very short.

On the first day, as soon as I got home, I hurried to ask my mother, "Mom, do we have mung beans at home?" Mother said, "What do you want with mung beans?" "Mom, the teacher asked us to soak mung beans and observe their growth." Mom said, "Yes, it's in the refrigerator." I took out a small plate from the cupboard, filled it with some water, and soaked the mung bean in the water. The mung bean slowly swelled.

The next morning, when I woke up, I saw the mung bean cracked, and a tender yellow rhizome grew out. This tender yellow rhizome was like a curved bean, so cute!

On the third day, I found a bud with a "little hat" coming out. I put a napkin to keep the bud moist.

On the fourth day, I was surprised to find that the "little hat" had fallen off, and two small green leaves appeared inside. After the sunlight, the stem of the bud turned purple, and after two days of waiting and observation, the bud had grown into a bean sprout.

After these days of observation, I think the growth process of plants is very wonderful and interesting.

The full-text language is vivid and interesting. It introduces the daily changes of mung beans into bean sprouts in chronological order. Finally, it tells you what I found in my observation: the growth process of plants is very wonderful and interesting.

Observation diary of planting bean sprouts in the fourth grade 8 Monday, September 7 th is fine

The second class today is seed germination in science class. After class, the teacher sent us several boxes and a dozen beans to do the experiment of seed germination.

Back to the classroom, I put a napkin on the bottom of the box, mung beans on it, a thin layer of paper on mung beans, and finally water. I decided to change water and paper once a day.

It will be fine on Tuesday, September 8

Mung beans didn't change at first. After class, I quickly picked up the box to observe mung beans. I found that the mung beans are wrinkled now, like the wrinkles of an old woman, like a newborn baby, and like a deflated ball. How lovely! It turns out that the douban of mung beans is hard. After soaking slowly, it will become very soft and swollen, and then there will be wrinkles. I really want it to sprout at once.

It will be fine on Wednesday, September 9th.

The first thing I do when I come in the morning is to see mung beans. Wow! It's sprouting. Great. I think I should plant it in the soil. So I dug a box of soil, pressed a hole in the soil, and put the beans in it. Finally, I turned the soil and watered the mung bean seeds every day, so the mung bean gradually sprouted and grew leaves.

Observation diary of planting bean sprouts in the fourth grade 9 10 3/0 Weather: sunny.

Today, I got up and brushed my teeth. After breakfast, I went to get a paper cup and started to get mung beans! I put mung beans in a paper cup, and then add water to the paper cup. Then put the paper cup on the balcony and began to soak mung beans. I want mung beans to sprout and grow up quickly. Mung beans are hard today, so they should sprout a little the next day! I sat by and waited and looked forward to it.

104 weather: sunny

Today, my little mung bean really sprouted a little! The buds are white, some mung beans have peeled off, and the whole body is bare. I was surprised to find that there was a green line at the water level on the cup. Why? I asked my mother, and she said, "Mung beans contain green pigment, which floats on the water to form a green line." So that's it! I see.

10 5 weather: sunny

Today, the buds of my mung beans are a little bigger, and all of them are peeled off first. The green and white mung beans in the cup are very beautiful. I took a pen without ink, and tried to press the mung bean skin floating on the water. One mung bean skin was pressed down and floated again. I pressed it down and it floated again ... Later, I thought of a clever idea, that is, pressing the green skin under the white mung bean. Sure enough, it succeeded, and it didn't float again. Do you know why, children?

I am very happy! I am looking forward to the day when mung beans can be eaten.

Observation diary of planting bean sprouts in the fourth grade 10 Last year, I saw my sister put the wheat in a glass box, covered it with a thin layer of cotton, and poured in some water. A few days later, the wheat germinated and grew bright green, long and thin leaves. It was amazing. But I have no wheat.

Last Sunday, when my grandmother and I went to buy mung beans, I said to my grandmother, "Grandma, I want to test how mung bean sprouts grow?" Grandma gave me five mung beans to do the experiment.

When I got home, I couldn't wait to find a big bottle and cotton. First put the mung bean in the bottle, then put some cotton on the mung bean, and finally pour some water into the bottle and put it in the shade.

After a few days, mung beans became much fatter than before. Looking closely again, I almost jumped with joy. The original bean green coat of some beans had been broken, and two pieces of white watercress emerged from the clothes. I poured some water very carefully again.

After school at noon the next day, ah! The mung bean sprout grows as high as 1 inch, and its body seems to be carved out of ivory, white as jade and beautiful. And the two pieces of watercress on the head bend down and lean against its body, just like a shy girl.

Another day passed, two small light green leaves grew between their watercress, which were beautiful, just like two small hands, greeting their partners and saying, "Grow them quickly!" See who grows fast. "

I looked at this little experiment, and my heart was sweet, so successful!

Observation Diary of Planting Bean Sprouts in Grade Four 1 1 Friday, the teacher sent us some mung beans for us to plant, and wrote an observation diary to see how mung beans germinated.

On the first day, I want to plant mung beans. I first prepared a small cup, then put a piece of gauze on the bottom of the cup and put mung beans on it.

The next day, I saw the coat of mung bean changed from dark green to light green.

On the third day, I saw that the mung bean's stomach was so full that it broke the green coat. Moreover, a little bud sprouted from the broken place, just like a little tadpole.

On the fourth day, in the morning, I rushed to look. Some small buds have grown to 5 mm long. They have all taken off their green coats and exposed their round white bellies. In order to make them grow better, I will take care of them carefully every day.

Through the observation these days, I found that the growth of mung beans is really inseparable from humidity, temperature and light.

Observation diary of planting bean sprouts in grade four1Sept. 30.

Today is the day before the National Day. After dinner, my mother and I started our "bean planting plan" with great interest. We both took a flowerpot, and I also took a shovel to dig in the community garden, because I wanted to plant soybeans.

It's already dark and drizzling. I found a pile of loose soil in the garden. My mother said that this kind of soil is not good. If you want to find clay, it is best to choose soil with lush plants. We filled two flowerpots with dirt and took them home.

I buried raw soybeans in the soil, and I didn't know how deep, so one flowerpot was buried deep and the other flowerpot was buried shallow.

In the evening, I lay in bed thinking about my little soybeans, hoping that they would germinate quickly.

Observation diary of fourth-grade bean sprouts13 July 16

I immersed 30 mung beans and several soybeans in a basin filled with clear water according to the method of scientific experiment to see what would happen the next day.

July 18

Mung bean sprouts are about 3 cm high, and each mung bean sprout has two slender, big and light green leaves. However, soybean sprouts only grow small buds less than 1 cm.

July 19

Mung bean sprouts are about 10 cm high, even as high as 12 cm long, and their leaves are longer and bigger than yesterday. Soybean sprouts grow very fast, about 3 cm, with small leaves, about 1 cm.

July 20 th

The height of mung bean sprouts is about 16 cm, and the height of soybean sprouts is about 18 cm. The leaves have become long and big. They could have been eaten, but they could not be eaten because they were soaked in unclean water. What a pity!

Observation diary of planting bean sprouts in grade four 14 Today, I soaked some soybeans.

I'll wash the soybeans first and put them in a basin full of cold water. The soybean hits the basin and clangs. This soybean is really hard!

When I got home at noon, the first thing I did was to look at my soybean babies. I found many wrinkles on their skins, and I thought to myself, "How did my soybean babies get so old at once?" So I called my mother and asked what was going on. Mom said that it is because the soybean skin absorbs a lot of water and swells, but the inside of the soybean is still very dry. When I looked at them again after school in the afternoon, their wrinkles disappeared and they became "babies" again. I wonder what kind of "rejuvenation" medicine they used, which has such a great effect? I asked my mother again, and her mother said, "Think for yourself.". I think it's because the baby soybean has had enough water in it, which has opened his wrinkles.

Mother asked me to pour out the water and put a soaked handkerchief on the baby soybean, saying that the baby soybean would sprout tomorrow.

September 26th

Today, as soon as I got up in the morning, I immediately ran to the basin. I thought the soybean babies had sprouted. But to my disappointment, they are still sleeping, and there is no meaning of "growing up" at all. In the evening, I went to see my soybean babies again. I was surprised that they all gained weight and could hardly wear their clothes.

September 27th.

Today, I got up early, because I want to see what my baby soybean looks like. I came to the basin, ah! My baby soybeans took off their coats and put on their hats. I gave them a "cold bath", covered them with a "small quilt" and put them in the sun to let them enjoy the warmth of the sun.

September 28th.

Today, the "hat" of my little bean sprouts has grown to three centimeters, just like the antenna on the communication equipment, and it seems to convey something. I jumped three feet high! I said to them, "You must grow well and grow taller." They probably understood what I said. I seem to see them shaking their small antennas, growing harder than the competition. It seems to say: Let's see who grows soybean seedlings first ...

Observation diary of fourth-grade bean sprouts15 September 17

"I'm back! Hurry up, bring me some soybean seeds, I want to observe! " As soon as school was over this afternoon, I ran home at lightning speed and shouted at my parents. What are you doing? It turns out that the teacher has assigned a very interesting task, so that we can observe some changing things continuously. When I was inspired, I thought of soaking soybeans and watching them sprout.

Mom and dad sent soybeans in a hurry, and I looked at them carefully. The color of soybeans seems to be khaki, a little close to skin color, and it seems to be a little yellowish. I can't tell the color of soybean clearly, and I can't draw it. In short, it is a very special color. Some soybeans are oval, some are round, and some are bumpy and irregular. There are some wrinkled skins on the surface of soybeans, such as water ripples and wrinkles on the face of old people. Soybeans are hard and hard, so you can bite them hard in your mouth to get a little bit of tooth marks.

It turns out that soybeans are like this, and there are so many characteristics. It's really very insightful to observe soybeans so intimately for the first time!

September 18

As soon as I finished eating at noon today, I picked up the soybeans, put them in a plastic cup, filled them with water, and waited quietly. About half an hour has passed, and I am getting impatient. Is the skin of soybean really so difficult to shed? After waiting for so long, nothing happened. Just thinking about it, I don't know how long it will take, and I can't help but turn my eyes to the cup. "wow! Molting! " I slowly spread my frowning brows, crooked my mouth and smiled on my face. A lot! Soybean has become bigger and fuller than it started. Many soybeans have cracked a small mouth, and there is a fragrance in the cup. The beans have become smoother and rounder. I really hope it can grow up quickly!

September 2 1 day

After waiting for so many days, the soybeans finally germinated. I found it by accident in the morning.

Early this morning, I woke up and used to go to the balcony to see soybeans. Sharp, short white buds appeared on the head of soybeans, like pigtails of soybeans, which were very attractive. When I was excited, I woke up my parents, who were also very happy. I felt as if the soybeans in front of me had grown up and produced many tender beans ...

September 25th.

After another four days, Yaer began to become curly, curved, very playful and very cute. They twisted together like a group of dancing Indian snakes. This funny and interesting shape made us laugh.

September 29

The buds are still growing and thick, and the bean skin that has sprouted is beginning to rot. At first, I thought it was because there was no water and I was dying. I didn't expect that when I turned the cup, it was soybean sprouts peeling! It takes off its ugly rhubarb pajamas, revealing a layer of green and smooth body, which is particularly lively and powerful, very youthful.

Ah, the future soybean seedlings will be more beautiful. I will always look forward to it, looking forward to it, waiting for it ...

Observation diary of planting bean sprouts in the fourth grade 16 I think everyone should have planted plants! Today, I'm going to plant mung beans that have sprouted a few days ago into a small flowerpot.

Just do it. I found a flowerpot and found that there was soil in it. I thought: Haha! God help me! So, I pressed a few small holes in the soil and put the mung bean sprouts in it, so that a mung bean sprout was planted. But it's not that simple. Just when I was proud, a breeze blew and the mung bean sprouts just planted fell down, and I was disheartened at once. Hey! Am I really incapable of planting? I don't believe it. Start from the beginning and try again! However, I tried again and again, and the mung bean sprouts fell down again and again.

After I failed again and again, I finally found the problem. I continued to put the mung bean sprouts in the hole. Then, I held the mung bean sprouts in one hand and put some soil on the root of this mung bean sprout in the other, and then pressed it tightly, so it was planted. With full expectations, I breathed a sigh of relief at this mung bean sprout, but it didn't fall down! I jumped three feet high with joy, and then I planted several other sprouted mung beans in this way.

"Hey? Something seems to be missing? " I said to myself. At this time, I looked at the dry soil and said, "water, it's water!" " I took the kettle, put some water in it, and immediately poured some water on the mung bean.

"Not good! Too much water! " I cried loudly, complaining that I had done another wrong thing. There was nothing I could do. I had to put the flowerpot at the door and let the mung beans bask in the sun, hoping that more water would evaporate quickly. Seeing the mung bean sprouts planted by myself alive in the sunshine, my heart was filled with joy.

Through this incident, I learned a truth: if you fail in anything once, you should not lose heart. You should do it again and again to gain more experience. Failure is the mother of success. If you don't fail, you won't succeed.

Observation Diary of Growing Bean Sprouts in Grade Four 17 My mother bought a bag of mung bean sprouts after coming back from work, and asked me to try to grow them myself. I jumped three feet tall with joy.

first day

I put mung beans in a bowl and prepared to give them a bath. I added a little water to the bowl, and the water in it was very turbid, so after a while, I also poured out the water in the bowl, and then continued to add water. I slowly found that the small mung bean suddenly became a big mung bean. I touched it carefully for fear of shocking the mung bean. I said softly, "good night, little baby!" "

the next day

I can't wait to come back to see my little baby, and I found that they have grown small tails and taken off their coats, like little tadpoles and the letter A. I hurried to change the water, like an ant on hot bricks. After I changed the water, I ran back to my room to do my homework.

the third day

As soon as I get up in the morning, I go to see bean sprouts. The surprise side appeared, and the small bean sprouts grew so long that the bowl could not be squeezed. They are crowded with each other, as if to say, "Don't squeeze me, I'm dying. I took them out and put them in a flowerpot.

The fourth day

I got up in the morning and hurried to see the bean sprouts. The bean sprouts are all broken, revealing a small leaf. And they all crowded the flowerpots, and the leaves were like a pair of scissors.

This is my record of bean sprouts. Will you visit my bean sprouts, too?
