In the usual study, work and life, everyone will always come into contact with the composition. According to the characteristics of writing proposition, composition can be divided into propositional composition and non-propositional composition. I believe many people will find writing difficult. The following is a 350-word observation diary composition I collected for reference only. Welcome to reading.
Observation diary composition 350 words 1 In the evening, I stood on the balcony and rested, inadvertently looking up at the sky. ...
Wow! I almost cried. There are so many clouds in the sky, layer by layer, in clouds, in piles, white, and there is a blue sky behind, which is even more white as jade. Some of them looked at me angrily and scared me out of breath. Some are like a cute little white rabbit, and I can't wait to fly to the sky to touch its furry hair; Some are like white bear chasing games; Some are like "flying immortals", flying to the distant horizon; Some are like cotton candy, which looks soft. I really want to fly to the sky to take a bite; There are waves, the sky is like the sea, splashing more than one spray, and the waves roll and roll in the sea. ...
After a while, tigers, white rabbits, marshmallows, mountains and waves all piled up. The sky is like the sea. Piles of overlapping white clouds roll like waves, surge like waves, and roll in the sea. Some clouds gradually separate and become "islands in the sea" ...
Sunset, accompanied by sunset glow, slowly sets. How red! The surrounding white clouds are as red as a red dye vat.
I saw it was getting dark, so I reluctantly left the balcony and went back to my room.
Suddenly I wanted to observe the growth process of pear trees, so I found a pear, picked out the seeds and planted them in the soil. I was very happy after I poured some water on it. I thought it grew up, so I planted it in the open space on the platform, or gave it to my grandmother to plant in the ground. This morning, I can't wait to see my pear tree. A miracle happened. Under my careful watering, it finally germinated. The two small green leaves exposed by it are beautiful. I've watered him and pulled weeds every day these days, and now it's finally sprouting. At that time, I was very happy School is about to start, and I am nervously preparing my holiday homework, but most of my free time is spent planting pear trees. After lunch, I went to see my pear tree again. At that time, my pear tree was about 7 cm high and had four leaves, green and shiny. Although the trunk is still thin, it looks much thicker than before. Seeing the fruits of my labor, my heart is full of joy, sweeter than eating honey. When school started, I studied hard, but I still didn't forget the pear tree. Every time I go home, I immediately go to see my pear tree. When I saw it, it grew really fast, 10 cm high, and two new leaves grew. The breeze blew, and it nodded at me, as if it were happy to see me and say hello to me.
I like peach trees, persimmon trees and apple trees ... but I prefer the grape trellis in our school.
Stepping into the school gate, the grape trellis I mentioned is on the right hand side, which adds a lot of color to our campus.
In the past, the grape trellis was painted green, but now it's very different. It is painted a beautiful crimson, and the green grape leaves are very matching and dazzling.
In physical education class, we went to the playground and waited for the teacher. We can't wait to sit on the long cane chair under the grape rack, lean on the red shelf and look at a bunch of grapes overhead. They look like pearls carved from crystal and jade, purple and turquoise, like agate jade, which makes people drool. In addition, the sun shines on grapes, making them more crystal clear and attractive.
Grape leaves are also beautiful, as big as the palm of your hand, thick green and light cyan. Under the guidance of the breeze, the leaves began to dance in groups, and the grape leaves twisted with the "dance" of the leaves. I couldn't help laughing sweetly.
Jingle bell ... the bell rang and I reluctantly left. I nodded like a grape, and the grape nodded to me.
I love our campus, especially the grape trellis on campus.
Observation diary composition 350 words 4 September 10 Wednesday weather: cloudy
It's autumn now, and the surrounding trees are beginning to change. A ginkgo tree in the north of the school looks very tall and lush, and it is still in its heyday. In fact, it has changed a little. Some leaves have turned yellow, but they are not obvious yet. Some branches have lost a leaf or two and fell to the ground.
Weather on Friday, September 15th: Rain.
Most of the leaves of that ginkgo tree are a little yellow, and more leaves have fallen off. The lowest branch on the ginkgo tree has no leaves and is empty, leaving only brown dead branches. It's raining today, because of the wind and rain, more leaves have fallen off.
Weather on Saturday, September 20th: sunny.
Ginkgo biloba leaves are becoming more and more yellow, and there are more and more fallen leaves. Autumn is coming, the season when fruits are ripe and the season when green leaves turn yellow is coming. In this season, we can taste delicious fruits, see the leaves spinning and falling, and hear the rustling of leaves being trampled. Well done! Let's welcome the arrival of autumn together!
Today, the school organized us to visit the Han Meilin Art Museum, and the students were very excited. When I entered the art gallery, the first thing I saw was a grand piano with many famous people's signatures on it. Then I saw the big horns, but strangely, they were not symmetrical. They go up and down, which is very interesting.
After a long passage, we entered the first exhibition hall. There are many Jun porcelain in the first exhibition hall. Grandpa Han made them into the shapes of kittens and small fish. In addition, Grandpa Han painted 65 different cute owls and 65,438+000 different fish. It only took him three hours to draw these fish.
We came to Fuwa again, and after listening to the explanation of the commentator's aunt, I suddenly realized that the logo of the Olympic Fuwa was designed by Grandpa Han!
Later, I saw a huge Buddha statue. "How tall and heavy is this Buddha statue?" The interpreter's aunt told us that this Buddha statue is as high as 12.5 meters and weighs 90 tons. Unconsciously, we walked out of the art museum, and we reluctantly bid farewell to the art museum, which I will never forget.
After learning this unit, the Chinese teacher in our class, let's do an interesting experiment-do a small experiment of soaking eggs in vinegar and write an observation diary.
As soon as I got home, I found a glass jar, raw eggs and white vinegar. First, gently put the raw eggs into the glass jar, and then pour in the glutinous rice vinegar with the degree of 9g/ 100ml, so that the vinegar can't beat the eggs. I turned my head to one side when pouring vinegar. The smell of vinegar is too pungent!
As soon as the vinegar was poured into the glass jar, the eggs changed immediately. There are many small blisters on the surface of eggshell, which reminds me of beer foam. After a while, the blisters disappeared. After a while, blisters appeared on the eggshell surface, and more and more, like a group of naughty dolls, you wouldn't let me let you.
The next day, the egg seemed to swell up like a balloon!
I touched it. Ah, it's exactly the same as peeling an egg after it's cooked. Very soft. I accidentally dropped it on the table when I took it out. Hey! It didn't break, but it bounced like a ball! I was shocked!
I took a closer look at this magical little guy under the lamp: its surface is smooth, its color is like the rising sun, and it is elastic. When I put it back in the jar and knew that it was elastic, I was not afraid that it would break. I threw it into a glass jar, and it jumped up and down in the jar like a diver.
I found a chopstick and poked it. The egg liquid is light yellow when it comes out. But now, the egg liquid is dissolved in vinegar, and the color becomes golden yellow.
I know that vinegar will have such a wonderful change when it meets eggs!
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!
Observation diary composition 350 words 8 This afternoon, the teacher asked us to go home to soak mung beans and write an observation diary.
So, as soon as I got home, I searched all the boxes for mung beans. Finally, as easy as blowing off dust, I quickly found a bag of mung beans.
I took a bigger iron bowl, added about half a bowl of water, put a handful of mung beans in the bowl, took it back to my small room and began to observe it carefully.
I sat in a chair, took out my diary, sat there quietly observing and writing slowly.
I looked at it, and some strange and interesting ideas came to my mind: why hasn't mung bean changed at all? Will it stop the biological clock? Is its soul out of body experience? Really ... I've thought about it for a long time, but I still can't figure out why. So, I ran to ask my mother. Mom just whispered, "You can't eat hot tofu if you are impatient." What mom said was so profound! I don't understand at all.
The next night, I found that mung beans sprouted, small and white as if they had a small tail. How cute!
I think he took off his beautiful green clothes at all costs, without any reason, just for cuteness.
The water in those bowls filled with mung beans changed color, from transparent to semi-purple and semi-yellow, but it was still a little transparent.
In order to see the internal structure of mung beans, I dissected my baby mung beans without hesitation. I found that the internal structure is like this: half concave and half convex. Recessed is the place where mung beans germinate, and protruding is the place where mung beans germinate.
If everyone can discover the magic and beauty of nature, then our world will be more beautiful!
In the flowerpot in the downstairs yard, a few eggplant seeds sown by grandma have been growing quietly. I carefully observed every step of its growth, germination, long leaves, flowering and fruiting until it withered.
Germinated. Eggplant seeds, which have been in the thick soil, finally leaned out shyly. It has a thin turquoise body and spreads its first leaf. There are some tiny Mao Mao on the leaves of eggplant, which may be because it has just grown up. There are many veins on the leaves, in order to better transport the water from the roots to the leaves, so as to leave the water in the leaves. The bud grows day by day, from 1.5 cm to 4 cm, and then to 13.8 cm, and this root is reddish and looks very nutritious!
A few weeks later, eggplant buds bloomed, but the flowers were not as beautiful as I thought. These flowers grow from the branches. First of all, a small purple stripe appeared on the branches and leaves, and there were many small protrusions on it. Gradually, this purple "small strip" grew up and cracked, revealing a hint of purple. After a few days, this "lavender" thing became bigger and softer. I finally saw it clearly. That is a small flower with six petals. It looks like six petals. When I looked carefully, it turned out to be one piece after another. It turns out that there are eggplant flowers in the purple strip! This purple strip is the sepal of this flower! The petals of this small flower are so thin and soft that they break when scratched. And there are many purple stripes on this little flower, which is very beautiful!
Observation diary composition 350 words 10 On the day of science class, 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 opened the soil, I saw that the original soybeans had grown pale yellow buds. 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 bright green and very attractive. 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 have harvested 10 pods and more than 20 soybeans!
Observation diary composition 350 words 1 1 Today I observed ants. Every ant is like a sesame seed. It is small and looks lovely.
First, I found an ant. Careful observation reveals that there is a small pair of scissors on the ant's mouth. Scissors swing with the movement of ants, making the little ants look powerful and strong.
Because all animals will return to their nests after being frightened, I gently dialed it, and it sensed my danger and ran away desperately. I followed it all the time, and it finally arrived. I saw a hole, only the size of mung beans, which seemed very deep. The ants got in quickly.
In order to observe more ants and how they eat, I asked my mother for a small piece of sugar. I put the candy in the hole. An ant walking around saw it. It panicked, ran around and was very scared. After a while, it calmed down and began to observe the monster carefully, approached it and tasted it, then entered the ant nest. Just when I wanted to observe in another place, I didn't expect it to appear in the back! A group of ants came out and surrounded the candy. Before long, the candy was covered with ants. They eat with their mouths open, and some ants go back to their nests when they are full, as if to put the food back into the warehouse. Soon the sugar was half eaten, and in a short time, the sugar was finished.
I was very surprised, because, for ants, such a huge monster was eaten up by them so quickly, and how powerful the team was! After eating the sugar, the ants lined up and returned to their nests one by one.
Today, I understand that as long as people are United and have the same goal, no matter how big the difficulty is, it can be overcome.
Observation diary composition 350 words 12 Three years ago, my little potted chlorophytum came to our house for the first time. It was still a tiny place at that time! When I first came, I was still a stranger. Before I visited our home, my mother put it in a corner of my cabin.
It lives with my favorite doll, so they become good partners. I like this cute little guy very much. I water and fertilize him every day. It is growing bit by bit. When it grows very long, my mother hangs it on the wall with a hook, which is very beautiful.
It's our cleaner It "eats" all the dust on the wall of my hut every day, even the dolls around it have no dust. Is the great hero of our family!
One day, I went into my cabin and closed the door behind me, but I used too much force and broke the chlorophytum on the door. Chlorophytum crying, crying very sad. It is afraid that it will never grow again. I am also very sad and regret it. So I went to ask my mother: will the broken chlorophytum grow back? Fortunately, my mother said the answer I wanted to hear most-yes! Mother said: "Chlorophytum has a strong vitality. Although its branches and leaves are broken, they will still grow. " Although it can still grow, I still feel sorry for it. After all, I broke this spider plant. So please close the door gently.
After a period of careful care, this little guy, oh no! It should be called big guy, it can already surround half the room! The more I watch it, the happier I am. I hope this pot of chlorophytum can survive in our house all the time!
Observation diary composition 350 words13 On Sunday, July 28th, the weather was fine.
In today's composition class, the teacher made a cup of Tieguanyin tea for students to observe. I have drunk a lot of tea, but this is the first time to observe it carefully.
There is a glass water cup on the platform, which is smooth and bright.
When starting to make tea, the teacher tore open the bag, then poured the tea leaves into the cup, and then poured the hot water into the cup. At this time, I found that the tea leaves gradually dispersed, some floated to the surface and some sank into the water.
I looked at it carefully for a while, and it seemed that the cup was like a castle. The tea in the castle was like a beautiful little princess, playing with her wand.
The level in the cup is quiet, some tea leaves sink to the bottom and some float on the water. Look, that piece of tea is floating in the middle of the cup, as if dancing; Watch that movie again. It sinks and floats. Probably performing acrobatics. Look, here comes another piece, sinking like a fallen leaf. ...
Slowly, the color of tea is getting stronger and stronger. The teacher brought me the cup and I put my nose close to the mouth of the cup. It smells really good!
Today, the teacher made tea for us to observe, which is really interesting!
Observation diary composition 350 words 14 greedy and sleepy, with a small antenna on his head and a big house on his back. Guess who it is? It's a small snail. One day, I went to the forest park to play. Suddenly, I saw a black thing on the wall. When I looked carefully, it turned out to be a small snail. I took it off and put it in a box, and ran back to the classroom to observe it carefully. Science books say that snails rarely have left-handed shells. I looked at the snail I caught today. Its shell turned out to be left-handed. I am really lucky. Snails like to eat cabbage, lettuce, bamboo shoots and green vegetables ... when they eat, they stick out their "teeth" to tear off the leaves and put them in their mouths to chew. I tell you, it has 25,000 teeth, which is the animal with the most teeth in the world. Do you think it has many teeth? When I got up in the morning, I saw the snail sleeping and knocked on its shell with my hand, but it wouldn't come out. I knocked on the door again, but there was no response. I was angry and put it in the water. The snail was afraid, and quickly stuck out his head, as if to say, "I will never sleep late again!" " "I just took it out. But it shrank back at once, as if to say, "Ha ha! Fooled! Fooled! "I'm angry again. As soon as it poked its head out, I clung to its "small antenna". I was really scared this time. Before I let go, it quickly shrank its head back and never came out again. Do you think this little snail is naughty?
Observation diary composition 350 words 15 20xx August 24th Monday sunny
Grasshoppers living on the grass can be said to be "secluded in the mountains". Their dwellings are hidden, and with two powerful bouncing hind legs, it is even harder to catch them. As for me, I was lucky enough to catch a green grasshopper.
It should be an adult. I looked at its back. It has a pair of extremely thin brown wings, which helps it escape.
I took it home, put it in a small bottle, drilled several holes with an awl and put some grass in it.
Tuesday, August 25th, 20xx is cloudy.
Today, as soon as I got up, I immediately ran to the small bottle containing grasshoppers and found that all the grass I put in had some bite marks. Good, which means the grasshopper ate it.
I turned my eyes to the grasshopper again: it is lifeless today, isn't it affected by the weather? I don't think so. No matter what the weather is like outside, it is full of vitality.
Besides, it kept jumping around in the bottle yesterday, as if to break free from the cage. Today, it has nothing to do with it.
I stared into its eyes, and it swung from side to side! What's going on here?
Wednesday, August 26th, 20xx is fine.
It is sunny again today, but it is still very quiet. Facts have proved that the weather will not change the state of grasshoppers.
It seems to be dying and struggling forward. I see, it wants to return to the embrace of nature. I was relieved and carefully picked it up and put it back on the lawn. Yes, I can't imprison it because of my own selfish desires.
It's free.
