Fourth grade observation diary composition111102 Friday Yin

This afternoon, after class, Sun Anqi came to borrow my pen. I opened the stationery bag for her. One of the pens attracted her: on the yellow pen, a lovely bear was eating chocolate happily. This pen is not only beautiful, but also has a unique side function: there is a small hole at the top of the pen. Shake it gently, and a small blessing sign will appear: "I got 100" and "I was lucky to get full" ... I hate to use it at ordinary times!

Sun Anqi wants to borrow this pen, but I don't want her to choose anything else. She sat coquetry, covering her ears and not talking. I thought about it. She just used it. There is no need to be so stingy! Besides, the exam is coming, so I lent her my pen.

After the exam, I asked her for a pen. She looked flustered and stammered that she had lost it! I was shocked at once! At the thought that such a lovely pen would never come back, my tears suddenly fell down and I ran home with my schoolbag on my back. ...

Grandma advised me after knowing it: crying alone can't solve the problem, and she didn't throw it on purpose. See if you can find it next week. Is it not just a pen? Big deal, buy another one! I feel much better when I think grandma is right.

After a while, Sun Anqi came panting to admit his mistake. She said that she went to four stores and didn't buy a pen of that style. Looking at her guilty appearance, my heart completely softened. Yes, it's just a pen. If you lose it, you lose it! I picked up a piece of bread and handed it to her. She gave a long sigh and we all laughed.

I went to Guzheng School as usual today (today is a music literacy class). As soon as we got downstairs, Mr. Liu stopped me and my mother and asked us to get the exam certificate.

My heart suddenly hung up and my grades were qualified? Okay？ Excellent? Recalling the scene of the exam, I can't remember it at all

I went upstairs trembling. The teacher smiled and handed me the certificate. I forgot to say "thank you" and went downstairs. As a result, I have been afraid to look.

Mother took the certificate, looked at it and said faintly, "Oh, it's qualified." My heart suddenly sank, just "qualified"! Soon my mother said, "Baby, you are great and excellent!" " "Oh, I grabbed the certificate from my mother and looked hard. Ah, it's really excellent! My heart jumped again, this time it was the kind of jump that kept jumping out, just like flowers blooming round and round! My memory began to recover: I got up early that day, my mother dressed me up beautifully, and my father stubbornly pulled the guzheng to the test center and asked me to practice my hand before the exam. ...

I carefully closed the certificates belonging to the three of us, carefully held them in my hand, made a face at my mother and confidently walked to the literacy class classroom!

The fourth grade observation diary composition 2 September 3 Friday sunny

Today, my mother bought me two rabbits. One is that the whole body (including eyes) is black. One is white and the other is brown.

They have round eyes, long ears, short tails and soft hair. They are very cute.

Rabbits like carrots and vegetables best. I cut the carrots into pieces and handed them to their mouths. They immediately leaned in, you bite me. Rabbits have three mouths and two sharp and long front teeth, so they leak food when eating. Wipe your mouth with your front paws after eating. It's quite clean!

It rained on Saturday September 4th.

The rain stopped. I took the rabbit to the lawn and opened the cage. Two rabbits poked their heads out, looked left and right, and then came out of the cage together. Soon, they found fresh grass. At first, they bowed their heads, smelled and tasted, and finally ate boldly.

After a while, the rabbits were full and they were jumping on the grass. I can't catch them if I want to!

I pulled out all kinds of weeds and fed them to see which one they liked best. But they all love it!

It rained on Sunday, September 5th.

It's raining today, and it's a little cold. The two rabbits snuggled up to each other and couldn't eat. It turns out that they are still sleeping. Small vertical ears are flat and the whole body shrinks.

I removed the rabbit cage and found a layer of small particles, dry and round, like peas. This is rabbit shit. Later, I learned through observation that rabbits are pulling while eating!

Two little rabbits are still very naughty. They often grab food to eat. Sometimes you push me and push me, scrambling to climb, and sometimes you stack arhats and climb assiduously. It was fun!

The weather is fine on Friday, April 23rd.

Today, the teacher called us kind of garlic. After school, I asked my uncle kind of garlic's method. I picked a good garlic first, broke it, peeled it one by one, and my uncle helped me wear garlic one by one. Then he took a small pot and put the garlic upside down twice. Finally, he added some water to the small basin and put it on the balcony to let them see the sun.

Saturday, April 24th will be sunny.

I woke up early this morning and saw a white beard on every petal of garlic head. When I came back from school in the afternoon, I found three cloves of garlic with 5 cm green buds on my tail. I gave them new water.

On Tuesday, April 27th, it was cloudy.

When I came back from school today, I saw four cloves of garlic sprouting a little green. There are also many garlic cloves with small mouths, all purple around them, and green inside the small mouths. It is estimated that buds will grow tomorrow. Why are there still some small mouths that haven't cracked? My uncle told me that there are too few beards on their heads, and when the beards are much longer, they will sprout. The buds that grew a few days ago, the tallest one is 4 cm, and the others are all 3 cm high.

It's cloudy on Thursday, April 29th.

I am very happy today. Most of the garlic I planted has sprouted, only a few petals have not sprouted yet. Why? I let my uncle have a look, and he told me that the garlic seeds of these cloves are not good and the buds will be slower. If you can't get out for a few days, then don't. Only then can I understand that garlic, like people, has good health and bad health.

It will be sunny on Sunday, May 2nd.

This morning, I found that the garlic seedlings grew slowly. I measured them with a ruler and they were still as tall as the day before yesterday. Some tips turned yellow, so I gently pinched off the yellow with my hand. My uncle told me, "Don't worry, plants have a growth process. Planting with water will be slower, and planting with sand will be much faster. "

It will be sunny on Thursday, May 4th.

Today, I woke up to see that the longest garlic is 15 cm, and one or two garlic seedlings have two or three buds. I touched the garlic cloves and found them empty, which was very strange. I went to ask my mother, and her mother said, "Their nutrition has been absorbed by the growing buds." I think it's amazing

Dear children, have you ever seen a silkworm baby? According to my investigation, some people will feel very scared, and some people especially like cute silkworm babies. This weekend, I went to my cousin's house and met silkworms for the first time.

My cousin keeps a lot of silkworms. She put the little silkworm in an iron box, while the big silkworm and cocoon were put in a cardboard box. These silkworm babies are so cute! So, I couldn't control my curiosity, so I observed them up close. The bodies of young silkworms are almost all gray-black. If you look closely again, you will find that the color gradually turns from black to white from the head of the silkworm. The bigger the silkworm baby is, the more white parts it has until it turns completely white. Silkworm has three small bumps on its gray-black head. I think these should be the eyes and mouth of a silkworm.

Silkworm babies also want to eat like people, so I observed the scene of silkworms eating mulberry leaves. Some silkworms are very picky about eating mulberry leaves, and some are as "voracious" as I am, with a good appetite. When they want to eat somewhere, they immediately jump in. They eat a hole first, and then eat around it. Silkworms crawl slowly, but eat fast! Last night, my cousin put about seven pieces of mulberry leaves, and when he saw them in the morning, he ate them all. Silkworms eat mulberry leaves and leave only thick veins, just like tigers eat meat and leave only hard bones ... through communication with my cousin, I also know that moths come out of silkworm cocoons to lay eggs and hatch young silkworms. I used to think that moths gave birth to young silkworms directly!

Through this observation, I gained a lot. I still remember the feeling of just seeing silkworms-a little scared, but now I think these silkworms are cute.

I will observe more animals and plants around me in the future!

Fourth grade observation diary composition 51:observe mung beans on Tuesday in September 16.

Today, Teacher Sun left us an assignment to go home and soak mung beans. When I got home, I couldn't wait to take out a small bowl, filled with some mung beans and water. After a few minutes, mung beans did not change. After an hour or so, hey! I found mung beans wrinkled, like an old woman's face.

It will be fine on Wednesday, September 17.

In the morning, I got up from bed and went to see my little mung bean. Wow! My little mung bean skin cracked and bulged at the same time. My mother said, "That's the cotyledon of mung bean." After school in the evening, I hurried to see my baby mung bean. The "green coat" of some small mung beans has been taken off, leaving only a white pearl-like thing, and the teeth have grown. The water became turbid and fishy. I quickly changed some water for the little mung bean.

It rains on Thursday in September 18.

On the third night, the first thing I did when I went home was to see my baby mung bean. Wow! I can't help but be surprised that the little mung bean has grown so big. I put the mung bean on the table with a cotton swab and observed it carefully. I found that the buds of mung beans are longer than yesterday, just like tadpoles. These buds are several centimeters long! The seedlings are white, crisp and easily broken. The original seedlings had no leaves and were bare, just like stems, which were bare.

Through this observation of mung beans, I learned that as long as you observe one thing carefully, you will learn a lot from it. I also learned to be patient in everything.

Chapter 2: Observation of Silkworm Molting I once raised a silkworm baby, and I also learned a lot of knowledge in the activity of raising silkworm, such as its molting.

That day, I went home and opened the silkworm baby's box. "Oh, the mulberry leaves are dry and must be replaced immediately." I ran to the balcony and brought fresh mulberry leaves. I changed the mulberry leaves one by one, and the silkworm baby seemed to smell the fragrance of mulberry leaves. Twisted and rounded bodies climbed up one after another and gnawed around mulberry leaves. Suddenly I found that one of them was different: the body was light yellow and there was a transparent triangle on the head. It tilted its head and didn't eat or move. What is it doing? If you get sick. I'll put it in another box at once and observe it carefully.

After a while, I saw a crack slowly appearing on the silkworm's head, which gradually thickened and a small head emerged from it. At the same time, the small head in front of the head has no strength to droop and become dry. Yes! It's molting. I saw the silkworm baby's head shaking from side to side frequently and stretching forward hard. But the epidermis is not obedient and sticks tightly to it. Why do silkworms shed their skin? I am determined to understand it. I quickly found the answer in extracurricular books: the hatched silkworms grow up slowly by eating mulberry leaves, and when the body is restricted by the epidermis, the silkworms will shed their skin. Usually molt once every other week, four times in a lifetime.

At this point, the silkworm baby has completely emerged from the epidermis. The newborn silkworm baby is whiter and fatter than before. It is admirable that silkworm babies do not suffer from molting in order to spin silk and make cocoons.

Chapter 3: Observing Ants After school at noon, I found a small group of ants in front of my house. I walked over curiously.

These ants are red, with about six or seven hairs on their feet and a pair of small tentacles on their heads. Some ants are several times bigger than others. They should be officials.

Not far from the hole, there is a big caterpillar. At this time, several ants rushed up like soldiers. At this time, the big green bug was bitten by an ant and rolled straight. The big caterpillar is as angry as an angry beast. It seems to say, "although you bite me so hard now, I will hit a little thing like you sooner or later." At this time, the big caterpillar turned over and the ant was overwhelmed by the big caterpillar. At this time, a small ant immediately fled to the mouth of the cave. I thought it was chicken out. Without thinking for a while, a lot of ants emerged from the hole. It turned out that the little ant didn't escape from the chicken just now, but went to move reinforcements. The ant colony at this time is like rows of soldiers. Soon the caterpillar was covered with ants, and then it was bitten all over the floor to find its teeth. Soon the big green bug was bitten to death. Finally, this big caterpillar became the ant's dinner.

Chapter IV: Observation Diary of Three Kinds of Garlic Seedlings 20xx 165438+ 10+0+0+0+0+0+0+0.

The Quaker's name for Sunday

In order to cultivate our observation ability and writing ability, the teacher assigned a special homework today-planting garlic seedlings.

After school, as soon as I got home, I took two fresh garlic and sat by the coffee table to peel them. It is not easy to peel fresh garlic. Gently rub it with your hand, and the outer skin will be easily peeled off. But the innermost skin is tightly attached to the garlic cloves, which is really difficult to peel. So, I rubbed it hard with my thumb and rubbed it a few times before erasing it. It took me more than ten minutes to peel both garlic. Then, I put them in a small plate. That garlic is like a beautiful Bai Lianhua. With a little clean tap water, the lotus is lifelike.

Friday, June 0, 20xx is fine.

the third day

Today, I found that some garlic sprouted a little, some grew about a millimeter, and some grew a centimeter! There are some white roots at the bottom of garlic, like grandpa's white beard.

Tuesday, June 0, 20xx will be fine.

Seventh day

Garlic seedlings grow so fast! Some have grown more than a centimeter. However, as individual garlic became "thin", Bai Lianhua began to shrink slowly. The longer the fibrous roots at the bottom of garlic are, the more connected they are, and the garlic in the middle can't even be pulled up by eight buckets. Garlic seedlings were light green at first, but as they grew up day by day, turquoise buds appeared on the stems, which looked like a small onion. No wonder the garlic sprout grows so fast that it drinks all the water in the small plate.

I think: if I were a garlic seedling, I would grow more than a centimeter a day like it.

Chapter 5: observing beans I've always wanted to see how beans germinate. On Monday, I began to soak beans. I found a cup and added water. I picked up a black bean and carefully put it in the cup. "plop!" Pick up a peanut, "plop!" Another black bean and a peanut were put into the cup by me one by one. Although these four lives have not yet awakened, they have sprouted in my heart.

On Tuesday, I ran to the cup as soon as I got up and couldn't wait to see it. Alas! I'm a little disappointed. Those beans didn't sprout. I really want to shout "Hey!" to those beans! Wake up! " But I held back. I can't be so impatient, maybe it will be fine in a few days, I comfort myself. After a while, I forgot about it.

On Wednesday, my heart was pounding to see peanuts and black beans, and I was prepared. Alas! It's not cute yet, but it's swollen a lot, chubby and really pleasing. Although I didn't see them sprout, it would be nice to have a "little fat bean"!

On Thursday, looking at those four swollen beans, I felt more confident. Maybe they will sprout soon.

At school, the teacher asked us to exchange observations, and I realized that beans could not be completely soaked in water. It's really angry and funny.

A week has passed and the beans have not germinated. Although I hold the water level as high as beans. Throwing caution to the wind, I am going to spend the "Eleventh" time to continue observation.

Another Tuesday, my first peanut sprouted. It cracked a little gap from the top of the peanut, revealing a little white bud, which was very cute. I feel very fulfilled and happy. So the first life was born.

On Friday, the second peanut also sprouted small white buds, which made me full of confidence in their growth. Look at the first peanut. His buds are already very big. I observed for twelve days-five days a week, and my time was not wasted, as my parents often taught me: "If you give, you will get something back!" "

Chapter 6: Observing Thrushcross Birds 20xx August 30th.

My uncle has a little thrush, three weeks old, with sparse feathers. Because she left her mother too early, she couldn't find worms to eat, and she couldn't swallow the bird food. So my uncle and aunt get up every morning and go to the grass in the community to catch five bugs for her to eat. Uncle put the little thrush in my hand, and the little thrush jumped around in my hand, making a small chirp, as if looking for his mother! I reluctantly left my uncle's house.

20xx September 16

I've been thinking about that bird for days. Today, I came to my uncle's house and saw that the birds have grown up a lot and their feathers are full. It can bathe by itself: peck a little water, touch the feather with its mouth to make it wet, peck a little more water, touch the feather with its mouth to make it thoroughly wet, then spin it dry and wash it several times. It still hasn't forgotten me, and it's good for me. Curiously touched its mouth with his fingers, it opened its mouth, gently bit my finger in it, and then let go; Sometimes I peck my hand gently! I had a happy Sunday!

20xx September 23rd

I threw a bug across the cage to it, only to see it cocked its head. When it carefully observed the movement and felt that the feeder was harmless, it suddenly craned its neck and picked it up. After catching the food, it immediately retracted its neck, stood on the stick and ate it with relish. Its neck stretched and contracted in less than a second and was eaten. How clever! When he is full of food and drink, he will dance in the cage, jump on the cage board for a while, fly to the shelf for a while, and sometimes accompany himself with cheerful songs, not to mention how happy he is! Don't think it's just a greedy guy. If you go to your uncle's house, you will personally feel its hospitality. It will "goo goo" to express greetings to everyone. How cute!

20xx September 30th

It gradually grew up like other adult thrush birds and became a light brown bird with a sharp and hard mouth and an orange color. It has a thick white eyebrow behind its watery black eyes, and a circle of white fluff extends backwards around its eyes. I think this is the origin of its name. Its beautiful and smooth wings sparkle with golden light, and its smooth feathers stretch naturally, just like being oiled. The tail feather is wide and long, full of spirit. It puffed out its chest like a victorious general.

This lovely thrush adds more happiness to our life, and our whole family likes it very much.

Chapter 7: Observe the sunny days of bean sprouts in June 10.

I want to plant some bean sprouts. So, I took some mung beans, put them in mineral water bottle caps, filled them with a little water, covered them with a layer of wet tissue, and began to expect them to germinate. The next day, I opened the wet tissue and looked, yeah! Doo seems to be full of water, so he may be sleeping! The color also changed from dark green to light green. I said to them, "Du, don't be busy eating! Grow up! "

65438+1It rained on February 2nd.

Today, I opened the wet tissue again and saw the beans split in the middle. Mom said, "This one will have a leaf bud for a while, and the leaf bud will be between these two peas for a while." I was curious, so I took one from the inside and broke it off in the middle. There is a small bud hidden inside.

103, 65438+ Rain

Today, I can't wait to run to my little peas again. I opened the tissue and looked at it. I am so excited! It turned out that between the two petals of these small peas, a bud was pulled out, and this bud reached the head of the pea. Their green clothes, bean skin, have also taken off half. When I looked carefully, only one Doo didn't sprout. Some buds are on the top of beans, like the tail of a pig; Some buds are straight like spears; Some buds are very short, like a chicken's mouth ... how interesting!

65438+1sunny on October 4th.

At 4: 30 this afternoon, I went to find my beloved little Doudou again. Look! How tall this bud is! And it is straight. I measured it with a ruler. It's one centimeter! I drew a red dot on this bud as a compliment; Draw a blue dot on the shortest bud, which is encouragement. If this bean sprout works harder in the future, it will certainly catch up with other bean sprouts.

65438+1sunny on October 5.

Today, I looked at my little peas and found that the beans have changed little. However, I found that many peas have buds. Look! Those raised spears may go to war!

65438+1sunny on October 6th.

Today, I am excited to see my bean sprouts. These bean sprouts have grown again, and the longest one is 1. 5 cm, even the shortest one has grown to 8 mm. I asked my mother, "Why do the bean sprouts we usually eat grow so big?" Mom said, "that's because they don't just soak like this." They are heated and saturated with nutrients. " I finally solved the mystery in my heart.

65438+1sunny on October 7.

I went to see bean sprouts again today and found that many buds were only eaten a little by insects. However, one bud has not been eaten and is still thriving. Watching, I seem to hear their voices growing up every day.

Chapter 8: Observation Diary (3 items) (1)

I have nothing to do today, so I have observed the papaya tree planted at home. Because it has been planted for several months, this papaya tree has grown to my nose, and its leaves have become big and green, like a grotesque fan, which can also fan the wind! Its stem is still so fragile, as if a gust of wind could blow it off. There are "wrinkles" of different lengths on the stem, and there are several flower bones on it, which are green and small, just like a soybean. Looking down, a flower has opened, and its petals are white, long and pointed at the top. A gust of wind blew, and this little flower began to twist its slender waist, just like a beautiful little girl dancing in the breeze, so lovely. In the breeze and sunshine, papaya tree whispered to me, "Well, I am beautiful!" " ! You can also pick melons from me in the future! So you must take good care of me now, so that you can grow melons! "ah! This naughty little papaya.

(2)

It's windy today, and papaya tree is blown to the waist. The leaves on his body kept dragging the slender stems, and the flowers on the stems withered, his head drooped and he put on a gray-yellow dress. As the saying goes, "the old don't go, the new don't come"! Look! Two new flower bones, long and sharp, grew on the stem. Looking down, two very long things "broke through the stem". What is that? I have read it carefully with this question, but I still don't know. I asked my mother, and her mother shook her head curiously. Forget it, forget them, but there is good news, just the opposite-another leaf turns yellow, alas! Poor papaya tree, if you look at those leaves carefully, you will find that they also have acne, but they are yellow and even, just like drawing with a ruler. It's incredible. But except for the leaves that have just grown. Maybe this is one of their characteristics!

(3)

It rained in time today, which made my papaya tree drink his belly round, and it stretched out soft branches. Hi! I was surprised to find that one of the two unknown little things grew a leaf on the top yesterday. It's incredible, just one night! Hey! The magical papaya tree! I want to tell you one more thing. Yesterday, those Kobanawa bones began to unfold slowly. Small white flowers mixed with raindrops give off a little fragrance. At this moment, I suddenly found that the trunk of this papaya tree tree is much older, covered with circles and many new "wrinkles", just like an old man's face, but its branches, leaves and flowers are so full of vitality, which is really a little thing that people love and hate. I must take better care of it now and make it popular!

I love my papaya tree!

Wow, my chlorophytum has sprouted! Not long ago, I scattered some chlorophytum seeds in the flowerpot. After a spring rain, my chlorophytum has quietly poked its little head out of the soil! I just want to observe the growth process of my chlorophytum.

Early spring:

After several spring rains, my chlorophytum poked its head out and my little body arched out of the soil. The color of the leaves of the newly emerging chlorophytum is tender green, which is very similar to the tender skin of a newborn baby. It is pure without any sundries. After another heavy rain, the remaining lazy chlorophytum emerged from the soil one after another, and the whole flowerpot was green.

Early April:

The height of my chlorophytum has exceeded the height of the flowerpot fence, but I haven't bent down like a wicker. Still standing there straight, when the wind blew, they danced in groups again. The wind is like a beautiful melody. With the melody, the chlorophytum plants sway to the right and then to the left. When the "music" stops, the dance is over!

Mid-April:

Green algae haven't drunk natural dew for a long time, and their thirsty throat and eyes are dry. Tap water at home can't meet their needs. One and two, like little emperors, held out their little green hands in protest. These are the eyes of God, and heavy rain falls on them. Rain drops on the leaves of chlorophytum. Dictyophora thought she was a small raindrop, so she shook her arms excitedly and danced a happy group dance. With the beat of raindrops, tick, tick, tick. ...

At the beginning of May:

The leaves of my chlorophytum are falling to the ground. In recent weeks, my chlorophytum has become more and more comfortable. I give them a breast bath almost every other week. Now, they grow more luxuriantly. There is no room for so many chlorophytum in that small flowerpot. To this end, some chlorophytum was immigrated by me. I finally finished observing the growth process of chlorophytum. Gee, I'm so tired ...

Through this observation, my observation ability has been greatly improved, and at the same time I have taken a small step closer to nature. It's killing two birds with one stone!

Fourth grade observation diary composition 7 "soaking mung beans"

Xx，xx，XX，XX

Several students in the class have brought several pots of small mung beans these days. I began to observe the "journey" of mung beans.

On the first day, I walked by curiously. The chubby little green mung bean is still as cold as before. After two classes, I went to see it again and found that the coat of the little mung bean had shrunk and wrinkled like the wrinkles of an old woman. In the afternoon, I came to school and found that the mung bean seemed a little "hot". After school, I was still thinking: "Little Mung Bean, Little Mung Bean, I hope the imbecile will grow up soon!" " "

"Little mung bean' broken shell'

Xx，xx，XX，XX

Today, the small mung bean has successfully "broken its shell" and the small pea has finally "broken its shell". Xiao Doudou broke its shell and revealed a short "small tail". Xiao Doudou with a "small tail" is like a lively tadpole, very cute! Some small peas not only have a "small tail", but also take off their clothes, which can be naughty! I really hope our little Doudou can live a healthy, happy and interesting life all the time, and I hope it can bring us more joy.

Growth of small peas

Xx，xx，XX，XX

Small peas grow bigger and healthier. Small peas gradually grow small leaves. Small peas grow taller and taller. A gust of wind blew, and it nodded and bent down to me. I can't help but be happy when I watch the little mung bean grow up healthily and happily day by day.

After a few days of careful observation, I think we should also study and learn its powerful vitality, and I will study as hard as it and grow up happily.
