Observe excellent compositions

In daily study, work and life, everyone has written a composition, which can be divided into narrative, explanatory, practical and argumentative according to different genres. How to write a composition to avoid stepping on thunder? The following is an excellent observation composition I collected for you, for reference only. Let's have a look.

Observe excellent composition 1 In the afternoon, I was doing my homework and my mother was watching the computer. Suddenly, something jumped on my mother's back with a bang. My mother turned and said, "What's on my back?" My mother grabbed it when she was talking. When I saw it, it turned out to be a grasshopper. I said to my mother, "What a big grasshopper!" Mother said, "Go and get that glass basin with a lid." "There is a hole in the lid, which can let the air circulate. So, we put the grasshopper in the basin.

I have carefully observed the grasshopper. It is emerald green all over. It has a pair of brown slender tentacles that sway over its head like hair. It is really cute. Its head is triangular and a pair of eyes surround it. It has three feet, the front foot is short, the back foot is strong, and it likes to jump. As soon as I opened the lid, it jumped.

It crawls around in the basin, and its mouth moves around as if to eat. I asked my mother, "What food do grasshoppers eat?" Mother said, "It eats grass and rice leaves and is a pest. However, it is also useful and can be made into Chinese medicine to treat diseases. " Then, I went to my door and pulled out some grass for the grasshopper to eat. It didn't eat, as if to go back to the grass, so I let it go, and it flew happily into the grass and disappeared.

Observing Excellent Composition 2 Today, in biology class, the teacher brought us some small snails for us to observe.

I carefully observed our snail, its body has many wrinkles, its shell is hard, and its body is soft and white. When we want to catch it, we just need to touch its eyes, and it is easy to catch it after its body is shrunk. When the snail is asleep, you just pour some water on it and it will wake up slowly. We put it next to the desk where the books are in the classroom. It always climbs to our class's endorsement record paper and Wang Yiyang's erhu box when you are not paying attention. We named it "Leopard" because it is the champion of snail sprint in our class. Isn't it amazing?

As long as one lesson is given, it will "escape" and climb on the glass. After class, the students will immediately catch our snails and put them in their nests. We brought him green vegetables to eat. When he eats, he has to put his whole body on it and eat slowly.

It's interesting to watch snails. Although the snail climbs slowly, it has been crawling as before through its own efforts. This spirit is worth learning.

There is a kitten in my sister's house called "Cut to the chase". Why is it called "straight to the point"? I'll tell you later.

From a distance, "Cut to the chase" is a small model with beautiful steps and a black-and-white skirt, which is beyond description. "Cut to the chase" will nod from time to time to show its high temperament.

It has a pair of eyes like black grapes, a long tail, pointed ears, a small mouth and a furry body. It's very cute.

I'll tell you why it's called "cut to the chase", because it has a black pattern like a mountain in the middle of its ear and two square plates like two doors on both sides, so it's called "cut to the chase". It loves sleeping, but it is not lazy, because it loves climbing trees, and animals that can climb trees are not lazy. "Cut to the chase" loves to eat fish. When it eats fish, it is very cute. Then he lowered his head, ate one side of the fish, and finally turned the fish over with his claws. After eating this noodle, he finished his meal. The cry of "straight to the point" is very vivid and interesting. When he is happy, he will feel excited and when he is sad, he will feel sad. This is my cousin's kitten. You said it was not cute.

I don't usually observe bees carefully, but what happened tonight attracted me deeply and made me interested in bees.

Perhaps, you all think that bees only buzz and sting all day, but I don't think so. I still regard it as a friend! In fact, bees are very hard and work hard every day. If it stings you, it will die! Because the needle behind it is its "needle of life".

In the evening, when I was doing my homework, I heard a buzzing sound. I took a closer look, and it turned out that a bee was flying on the screen window, which scared me. Later, I thought the bees were harmless, so I went to see them. Just as I was watching it with relish, the naughty little guy flew away. Maybe it's playing hide-and-seek with me.

This little bee is really cute and naughty. I observed that it gained knowledge!

Grapefruit is a kind of fruit that many people like to eat. It looked round and lovely, so I picked up a grapefruit and began to observe it.

Among many fruits, grapefruit is a big fruit. Generally more than one kilogram. It is oval, mature in the Mid-Autumn Festival, and also symbolizes reunion. When grapefruit is ripe, the skin is golden yellow. Smell a faint fragrance; The surface feels a little rough and there are many grains of rice. Peel off the thick skin of grapefruit, first reveal the thick white soft floc, and then tear off the outer membrane to reveal the crystal-clear pulp petals, and the slender pulp is tightly squeezed together, which is very attractive. Take a bite, and the juice will immediately fill your mouth, sour and sweet, with endless aftertaste.

Later, I searched the information about grapefruit on the Internet. It turns out that grapefruit is not only delicious, but also rich in nutritional value. Rich in nutrients such as sugar and vitamins.

I also learned that there are many kinds of pomelos, such as Shatian pomelo, Crystal Pomelo and Honey Pomelo. These grapefruit varieties are famous all over the country.

Students, you must have done experiments! I did it. Listen to me slowly. 65438+1October 29th sunny Sunday 65438+1October 28th sunny Saturday Today, I asked my mother, how did bean sprouts grow? Mom said, "It's the little mung bean sprouting." So, I ran to the kitchen and took some grains and put them in a small glass, adding some water. Then I began to observe the little mung bean, and nothing happened. I can't wait to ask my mother, why doesn't the little mung bean sprout? Mom smiled and said, "Silly boy! It will sprout tomorrow.

"I said," Oh, wait until tomorrow. "I got up the next morning and observed that the big belly of the little mung bean was full! I jumped three feet high with joy and shouted, "It's going to sprout! It' s cute! " I told my mother, and her mother smiled and said, "Right? I didn't lie to you. " I put it on the balcony excitedly and carefully. 65438+1On Monday, October 30th, when I came back from school at noon, I saw that the buds were already very long. Suddenly, I found that two mung beans turned purple. I asked my mother what happened to them again. My mother said, "The seeds are alive. Inanimate seeds cannot absorb water, so they will slowly dry up and rot. "I feel fine, but I didn't take care of them. After these days of observation, I finally know that there are really many interesting phenomena in the scientific community!

To do an earthworm observation experiment, the first materials to be prepared are: 10 earthworm, a covered black box, semi-dry soil and semi-wet soil. Then, pour wet soil on one side of the box, dry soil on the other side, put the earthworm in the middle of the box, cover it, and open the cover for observation after 5 minutes. Trial and error.

After three observations, my records are as follows: the first time: the number of dry earthworms: the number of three wet earthworms: the number of six middle earthworms:1; Second time: number of dry earthworms: number of two wet earthworms: number of six wet earthworms: third time: number of dry earthworms: number of two wet earthworms: 8.

So I can understand that if you look under the stones in the park, you can find earthworms, and if you look in the fertile place of the vegetable garden, you can also find earthworms; On the contrary, it is difficult to find earthworms by the dry roadside!

Observing Excellent Composition 8 The world is really big, full of wonders. Only by being good at observation and discovery can we see the "wonders" of this world.

One day, my father and I played badminton in the community. I accidentally hit the ball on the grass under a big tree. I went to pick up the ball under the tree and found that many snails appeared on the leaves and grass because of the heavy rain the day before. I asked my father, "Is snail beneficial or harmful?" Dad smiled and said, "You can observe the experiment yourself, and maybe you can know the answer to the question."

So I asked my father to take the racket and badminton home first. All I had to do was catch a snail and observe. I found a bigger snail, took it home, found a crumb and a small cabbage leaf, and killed a mosquito. I put these things in front of snails.

After a while, I saw the snail put out its head and tail, moved its short tentacles again, and then went straight to the cabbage leaves, climbed up the leaves, and ate up the small leaves in three or two times. From this, I can finally conclude that snails are a pest.

Through experiments, I know the secret that snails are pests, and I also understand a truth: as long as we observe carefully and use our brains more, we will get unexpected gains.

After observing excellent composition 9, I came to the robot world. There are all kinds of robots in it. Do you believe it? Look! Some can walk gobang, some can build houses, some can dance, some can sing, and some can dance swords. ...

I played a game of gobang with the robot: I put the sunspot in the center of the board-Tianyuan point, and he put the white chess on the right side of the black chess; I put black chess under Tianyuan point, and he put white chess ... Then, I put black chess next to white chess, and he ignored me and left. This makes me very happy, because I can take one more step to beat him! However, God forbid, he found that I had reached three pieces and put a black spot on the right side of those three pieces. Finally, I lost to him. Oh, by the way, I forgot to mention his appearance: a square "head" with a magnet in the middle and a rectangular "body" below, sitting in a chair, which is very awesome. The robot won the game and didn't forget to say, "Watch me!" " "

Time flies, and the sun sets in the blink of an eye. I reluctantly bid farewell to the Shanghai Science and Technology Museum.

Observe excellent composition 10 This morning, I played outside. Suddenly, the sky was overcast and thunder rumbled, and it was going to rain. I hurried home and found a small black line moving on the ground. It turned out to be a group of ants! Why do ants queue up for holes before it rains? A series of questions suddenly came to mind.

So, I ran home and turned on the computer to find out why ants came out of the hole before it rained. It turns out that ants are "small experts" in weather forecasting. Whenever it is hot and rainy, they will move from a lower hole to a higher hole, because if it rains heavily, rain will flood into their holes and they may be drowned, so they will move to a higher hole.

Later, I observed the activities of ants several times before it rained, and found that ants were not only "weathermen" but also "ticket sellers"! Look, how well the leader of the ant commands! Ants lined up, just like well-trained, with neat steps, sending messages to each other and carrying food, and the whole moving process was orderly.

Through this interesting discovery, my understanding of ants has further increased. Originally, in people's eyes, a very humble little animal can accurately predict the weather and get along well. It is an excellent team and worth learning from.

1 1 One day, I went to buy some mung beans, put them in a small bottle filled with water, and then covered them with a plastic wrap.

Next, I kept observing whether the mung bean in the bottle had changed. Two hours later, mung beans have not changed much, just increased a little. I think: mung bean, mung bean, sprout quickly. The next day, I saw the mung beans in the bottle grow some white and tender buds like tails, break out of their shells and come 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 to half the height of the bottle, and the leaves became bigger, and the leaves changed from white to tender green. Oh, the leaves have grown. On the fifth day, the leaves changed from light green to yellow. The bean sprouts have grown 4 or 5 centimeters tall, and some mung bean skins are still 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.

Observing Excellent Composition 12 My family has a small and exquisite goldfish, which is so cute that our whole family likes it very much. These two little goldfish live in my goldfish bowl, silent and carefree all day, with their tails wagging and carefree. When I fed them, they rushed to swim over. They are so cute.

One of the goldfish has a red spot on its head, like a red hat. Eyes wide open, mouth from time to time spit out small bubbles, like a naughty child, blowing bubbles. It is also wearing a suit of "armor", which is even cuter. Because it has a little red riding hood, I affectionately call it "Little Red".

Once, I was watching how it ate. I threw some fish material on the surface of the water, and they came up in groups at once. It was really hard to give way. The "bubble" occupied the size of his eyeball and grabbed one. His mouth opened and closed, staring at me wittily. Before I turned my head, he ate it early. Watching them share their "trophies" with relish, hundreds of question marks come to mind? He ran to ask his father, "Why can goldfish digest food without teeth?" Dad said, "Use your head." It's not difficult for me. I took out "100,000 Why" from the bookcase. This information manual contains the answer I have been looking for. A closer look reveals that goldfish really have no teeth. It turns out that water can soften hard things, so goldfish took the opportunity to eat them.

What a great harvest today!

Today, I did an interesting experiment, that is, I put some mung beans in a cup filled with water and observed its germination process. When I first put them down, they were like naughty children, running around in the cup. Some people were tired of running, so they fell asleep at the bottom of the cup. Some people seemed to have not played enough, and they floated on the surface of the water and poked around, so I picked up the ones that didn't sleep and threw them away.

I haven't seen them for two days. I wonder what happened to them. I found that mung beans are getting fatter and bigger than before. Unconsciously, they broke their green clothes, revealing their white bellies, but some mung beans still didn't change, and their clothes were tightly worn on their bodies, afraid of catching cold.

20xx65438+1Saturday, October 5th, sunny

Today is the sixth day of soaking mung beans. I can't wait to see mung beans. I was shocked. Mung beans have spit out white buds, which are about one centimeter long. The peeled mung beans are white and tender. It is really cute.

20xx65438+1Monday, October 7th, two days later. Mung beans are undressed and have sprouted. Some are like elephants' noses, some are like swans' necks, and some are like children who haven't slept enough, hanging their heads.

Observe the excellent composition 14 "Ding-dong, Ding-dong!" What is this sound so light? Oh, it turns out that summer comes with light steps.

Early in the morning, I came to West Lake Park alone to see the lotus flowers. Walk into the gate of West Lake Park. A faint fragrance came to the nose. "Ah, Lotus!" I shouted. Looking around, the pond is pink. Some are like shy little girls, in bud; Some are flowers and bones, struggling to stretch beautiful petals; The blooming lotus is like a slim girl, and you can already see the pale yellow stamens. So cute! When the wind blows, a pool of lotus flowers dances like a beautiful dancer. As soon as the wind stopped, many dragonflies flew in succession, looking for the lotus they thought was the most beautiful, stopping to have a rest and enjoying its beauty.

Lotus is not only beautiful, but also has noble quality. Although it looks beautiful, it is difficult to bloom such beautiful flowers in the mud. Although daffodils are more beautiful than lotus flowers and are appreciated by more people, daffodils grow in clear water. When the lotus grows in the mud, they never touch any soil. They try their best to make the flowers so beautiful. Therefore, many writers praise the noble quality of lotus in one sentence: muddy but not dirty.

Lotus is really beautiful, and its noble quality is worth learning. Be easy-going and survive in a bad environment.

Observing Excellent Composition 15 Today, the science teacher told us a very exciting good news-the silkworm baby ordered by everyone last week has arrived! Everyone was ecstatic, and the podium immediately rang into one.

What exactly is a silkworm baby like? Some students said that silkworm babies must be as terrible as snakes; Some students think that silkworm babies must be smelly and difficult to raise; Some students asked: "Is the silk spit out by the silkworm baby white or colorful ... Everyone has big question marks in their heads, and they all want to get the silkworm baby quickly and study hard.

Start sending silkworms! Everyone either craned their necks to see what was going on, or reached for the silkworm baby first. The students carefully took the lunch box sent by the teacher and put it on the table. Then I can't wait to open the box and observe it quietly. I saw six cute little silkworms crawling around in the breeding box. They are not as white and fat as we thought, but dark gray, rice-sized little guys. Silkworm babies are not like other animals. They have neither eyes nor noses, only a small mouth the size of a gray sesame. There are elastic bands on the baby silkworm, which can help the baby silkworm crawl. If you look closely, you will also find that there are round things under the silkworm baby's body, which are the "mini feet" for the silkworm baby to increase friction.

I really hope that the silkworm baby can grow cute and strong under my careful care!
