Fourth grade observation diary composition

Everyone has tried to write a composition in daily study, work or life. With the help of composition, people can reflect objective things, express thoughts and feelings, and transmit knowledge and information. Still at a loss for composition? The following are nine compositions in my observation diary for the fourth grade, hoping to help you.

Fourth grade observation diary composition article 1 My family has a cute little hamster. Let me introduce its appearance first.

It is covered with a white "cotton-padded jacket" with a gray arc in the middle, two big black eyes, a pair of cute little ears, a small flesh-colored nose and a cute little mouth. I was thin when I first bought it, but now I have become chubby.

It's weird, so it's really funny to say it's naughty. Otherwise, how can it not climb up and down all day, nor stop, or ask me to take it out to play; Suppose it's a warning. It is. If it hears anything while sleeping, it will go to the front of the cage and look around until it can't see anything, and then it will go back to sleep. Call it cowardice, and it is. If someone touches it while it is eating, it will run back to the cage in a panic, hehe, cute; Said it was smart. It is. Once, I forgot to feed it. At night, it goes to the kitchen to find something by itself. I searched for it for a long time but I couldn't find it. That afternoon, my mother went into the kitchen and saw it eating with relish. I said to my father in surprise, "Come and see, the little hamster has come to the kitchen to eat." The mouse seems to understand me. Hehe, isn't the hamster cute?

Since that time he went to the kitchen to eat vegetables, he thought more and more, biting the cage door all day. Fortunately, the cage door was locked by me. Otherwise, I may not find him now, and I don't know if he is happy in the cage!

This cute little hamster brings me a lot of fun. If you drop by my house when you have time, I'll rent it out. It-the cute little hamster will definitely bring you many surprises!

Observation Diary of Grade 4 Composition 2 It's sunny 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

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 the dew of nature 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!

Today, I planted some mung bean seeds. I put them in paper cups: first, put a napkin under it, soak it with some water, then put some mung beans on it, cover it with a layer of paper and add some water. Well, the sowing was successful.

65438+1Monday, October 2nd Weather: sunny.

Early in the morning, I couldn't wait to open a layer of paper towels on it. Ha ha! I found that the seed coat of mung bean was washed away by water, revealing a little white bud.

65438+1Tuesday, October 3rd Weather: sunny.

Today is the third day, and the white buds have grown up. Their strength is so great that they actually hold up the top layer of paper! I had to remove the top layer of paper that hindered growth. I found that the paper under the mat also became dry and wrinkled, and there was no water. I quickly poured some water to moisten it, hoping that the small bean sprouts would survive.

65438+1weather on Wednesday, October 4th: cloudy.

Ha ha! I found that several bean sprouts have grown very tall, about 7 cm. But there are also a few short trees, only 2~3 cm. The tall one has two small green leaves. The color is really fresh and lovely! The short one, without leaves, is a "one-man army" with a big head.

654381Thursday, October 5 weather: sunny

On the fifth day, everyone finally grew two small green leaves. They sucked up the water again, so I quickly poured some more water.

65438+1Friday, October 6th Weather: sunny.

On the sixth day, they grew much taller. The smaller ones begin to grow. All the seed coats have been completely removed, and white fine roots have grown below.

65438+ 10 7 Saturday weather: sunny.

On the seventh day, there were more white fine roots, thicker stems and larger leaves, but the two cotyledons looked smaller and smaller.

65438+ 10 8 Sunday weather: sunny.

On the eighth day, all the cotyledons on the stem have fallen off. The stem grows to about 15 cm. The bean sprouts were too crowded in the cup, so I transplanted them into the flowerpot. I wonder, will they continue to grow?

Fourth grade observation diary composition 5 "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.

This morning, my father and I went climbing the mountain and accidentally found a green snake in the ravine. I gasped in horror and quickly stepped back. This snake is about 1.5 meters long and about an inch in diameter. I saw it looking around, as if looking for something, and it seemed to be very painful. I asked my father, "What is this snake doing? It looks very painful. " Dad said, "It may shed its skin." I stood 50 centimeters higher than it, holding my breath and staring at it.

It rubs its upper jaw under a tree root less than an inch from the ground, and its head will come out of the broken place and go all out. I also cheer for it. It finally came out, and I'm glad about it. In this way, the skin on its neck finally fell off. Then the snake will shed its skin The snake stretched and shrank, and moved forward slowly. I think it must be very tired. It lay there motionless and rested quietly for a minute. After a while, it began to shed its skin again. The snakeskin fell off bit by bit. The snake raised its head slightly and kept spitting letters, as if it were very hard. Its muscles stretch and contract regularly. I finally molted, and the whole process took about 10 minutes. The snake shed its skin, just like putting on new clothes, and its patterns are very bright.

Why do you shed your skin? I went home and looked it up online. I know that snakeskin can be divided into epidermis, stratum corneum and dermis. The stratum corneum doesn't grow, so it should be molted every three to four months.

Today, I have really gained a lot. I not only saw the process of snake molting, but also learned the reason of snake molting.

In class, I saw the teacher take out two eggs from his schoolbag and put them on the table. Suddenly, these two eggs exploded in the classroom like two small bombs with question marks. Some students asked, "Teacher, what's so magical about these two eggs?" ? Is it different from the eggs we usually eat? "Some students asked," Teacher, what are you doing with these two eggs? "The other students asked," Teacher, are there any secrets in these two eggs? "The teacher didn't answer these questions, but smiled and said to us," Students, can you guess that these two eggs can spin? Without thinking, I said, "Yes!" Wen-yu li thought about it and said he wanted to turn around, but Song Wenhao said loudly, "No! "In this way, some people say they can turn, others say they can't.

At this time, the teacher loudly said to us, "Students, let's do an experiment." Then, the teacher picked up an egg and walked around the table. Ah, eggs spin fast and straight, just like a top. Just then, the teacher picked up another egg. The egg just turned and fell. Why is this? My heart is full of questions. Students, look at me and I'll look at you. They are all quiet, and the classroom is quiet. The teacher said slowly, "The eggs that can be turned just now are cooked eggs, and the yolk and egg white of cooked eggs are solid, so they turn quickly and steadily;" An egg that doesn't turn over is a raw egg, because the yolk of a raw egg is semi-solid and the egg white is liquid, so ... "

This experiment is really interesting! I think: in the future life, as long as we pay attention to observation and are diligent in thinking, we will find something and create something.

Fourth grade observation diary composition 8 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!

There is a beautiful garden downstairs in my house. The garden is small, but all kinds of colorful flowers bloom all year round. What a "hundred flowers garden"! Look, there are roses like flames, kapok like snow, tulips like golden sun in the garden ... Every day after school, I always forget to look at them when I pass by the garden, and my mood suddenly becomes happy!

During the summer vacation, I bid farewell to the garden and went to Shanghai. When I came back, I found a small seedling growing in the corner of the garden. As time goes by, the seedlings grow up and still hold long vines. What's more interesting is that some vines are still wrapped around the itchy tree and keep climbing! I wonder: what kind of flower is this?

When school started, when I went to school through the garden again, I found several lavender "small speakers" in the middle of the palm-sized leaves. My mother told me that the name of this flower is morning glory. I leaned over and smelled it. Ah, it smells good! I touched its white pollen with my finger again, just like chalk powder. How interesting! I can't help being interested in this morning glory.

One afternoon, I came home from school as usual and came to the morning glory again. "wow! When I went to school in the morning, the morning glory was still blooming brightly. Why is it all gone in the afternoon? " I cried in surprise, even wondering which naughty child picked the morning glory. Just when I was in a hurry to cry, I vaguely saw something hidden in the gap between the leaves of morning glory. I quickly put down my schoolbag and squatted on the ground to observe carefully. Only then did I find that no one had picked the morning glory. I didn't see the flowers, because the morning glory had faded. Oh, it turns out that morning glory is like dandelion flowers, and flowers are like our palms, which can be opened and closed. When a flower opens, it is lavender, so it is easy to be seen. When the flowers are closed, lavender petals are wrapped, which is difficult for everyone to find.

What an interesting morning glory! Since then, morning glory has become my favorite flower. In the morning, he played the trumpet and urged me to go to school quickly. In the evening, he put away his trumpet to remind me to finish my homework and go to bed early. Thank you, my beloved morning glory!
