One day, I finished eating a pear and was about to throw away the leftover pears. My mother said, "Give the ant the core." I listened and said, "It's winter. Where have all the ants gone?" My mother pulled me into the room and pointed to a small hole in the corner and said, "Look, it's right here." I squatted down and saw some ants crawling around in the hole. I saw it and thought, "Are there any ants in winter? Maybe it's because the room is hot! "
So, I put the pear core next to the hole. Soon, the pear core was discovered by an ant scout. It climbed to the edge of the pear core, touched it with its tentacles, and then ran back. I met an ant on the road. It touched its tentacles and continued to climb into the hole. After a while, many ants climbed out of the ant hole. I think it must be an army of ants. They climbed up the pear core like a group of peaks. They are biting off a piece of pulp with their teeth and moving it into the hole! In a short time, a pear core was eaten up by ants.
Why are there ants in winter? Why do we have to help each other? Do ants get lost when looking for food? A series of questions appeared in my mind. In order to find out these problems, I found out which one. After careful searching, I finally found the answers to all the questions. There are ants in winter, because if they don't reserve enough food for winter, they will go out in warm conditions and leave a smell. When it returns, as long as they walk back along the smell, they will definitely return to the ant hole, so that the ants will not get lost.
My 300-word observation diary composition really made my mother and I laugh and cry ... but later, I deliberately let the mouse go, scaring the daylights out of it, and it took several rounds.
The kitten is greedy, so it's time for the kitten to appear.
As soon as it saw the mouse, it pounced on it. I don't know how many mice it wants to eat all day. One is greed.
I remember one time.
Mother put the fish in the refrigerator and then went to do something else. The kitten jumped on the table and became the meat on the kitten's knife board. As a cat, I have a lovely kitten and jump up. The kitten is still so serious. I saw the kitten greedily eating the only fish tail left. Before the mouse took a few crooked steps, the kitten jumped up and stopped in front of her and surrounded her mother. The mouse had no resistance and was completely scared to death. Finally, my mother bought a fish to go home. I go to the apple box to get apples. Suddenly, a big, fat mouse got out of the box, which made me tremble. First, I rushed over to catch the mouse with my claws like lightning and made a hissing sound. It is wearing a black-and-white sweater with a pair of small golden bulbs embedded in its face, which shine at night.
When my mother went to get the fish, she found that the fish was gone, and there were two patrons standing at the corner of her mouth.
I remember one day, the obedient kitten saw the fish. ...
My observation diary composition is like a diary. Before the Spring Festival, my father bought me two little turtles.
One is Gao Gao, and the other is Xing Xing.
I give them this name because I want them to live happily every day.
When the little turtle just came back, my mother and I didn't know much about their living habits, so we put their "home" in a small fish tank with a little water and a few small stones in it.
Soon, I found Gao Hexing moping all day, his head, limbs and tail curled up in his shell all day, and he didn't give them any food.
At first, I thought it was because I might be timid in a new environment, but after several days, my mother and I were anxious. My mother said: "Turtles are amphibians, probably because they can't swim in this small' home' and can't choose a dry place to sleep comfortably. Try it in a big fish tank.
"Sure enough, as my mother expected, after putting the little turtle in the big fish tank, it didn't take long for the little turtle to swim around in the water, shuttle in the grass and play with the fish! Feed them and start eating.
Sometimes they open their mouths, wave their limbs and chase turtle food floating on the water.
Occasionally, it can be strung on the nails on the claws and sent to the mouth! My mother and I are so excited to see them happy! It turns out that the little turtle likes living in a free, comfortable and happy space like us.
The most interesting thing is that Gao Hexing bared his teeth when the turtle was oxygenated.
Sometimes they will still be motionless and let the water exhaled by the oxygenator be washed away; Sometimes they will lie on the grass and swing with it! When he wants to sleep, Gao Gao and Xing Xing will climb out of the water along the drain pipe and find a dry place to rest.
According to my observation, the little turtle is also very interesting to sleep: when he is in a good mood, he will stretch his head, limbs and tail to sleep, which seems to be very comfortable; When you are in a bad mood, you will put your head, limbs and tail in the shell to sleep, just like a black and green stone.
Gao Gao and Xing Xing, you must be very happy under my care, right? I have made you a part of my life.
Composition: My observation diary contains about 300 words of plants! I have seven lively koi fish at home. Some are big red, like a swimming little sun; Some are orange, like big oranges; There are colors, like strips of chameleon. The small fish is streamlined in shape and has a body length of 6~ 12 cm. I fed them fish food and minced flower rolls at the same time, and they seemed to prefer eating minced flower rolls. They breathe in today, and my little koi fish is very lively and lovely! When I was feeding, I found that they were all swinging their long, white tail fins and fins growing on their stomachs, grabbing food at a speed of 50-60 cm/s with their streamlined bodies and flexible tails. They were also very timid, and whenever there was any movement or noise, they would run around the pool. Sometimes when two fish collide, they will swing their tails and hit each other's dorsal fins, as if sending a message. When they swim, their tails are 98-65438. When I am angry or afraid, I quickly "hide" in other fish, as if I were afraid that others would see me. When eating, the mouth opens and closes like a trumpet, and food is sent into the mouth by suction. Just after feeding fish food, I saw a spot with a body width of 2 cm and a body length of 7-8 cm. koi fish spit out a dark green object with a body length of 2-3 cm from his mouth. After it vomited, I took a few breaths with my mouth and swam away. This white and dark green secretion may be food they don't want to eat, or it may be bad bacteria in stomach acid or water ... It seems that it is impossible to explore nature without rich knowledge. Today, I hung fish food on the hook and stayed in the water for 5 minutes. A greedy little fish swam over. Suddenly, I lifted the hook, and the fish swung its tail to 180 degrees, and its two ventral fins swung back and forth vigorously. Jump out of the water for 2~4 cm, and then fall into the water, stirring up the water vortex. I checked the information: Carp (koi fish) can really jump, the highest jump is 1 meter. Carps in rivers and lakes often jump out of the water to play at sunset. There is also the legend of "Carp yue longmen" among the people. Today, I want to change water for the fish. Before changing the water, the fish was quiet, as if. Still "waiting for the rabbit", waiting for it to sink. But just after changing the water, the fish all shook their fins and chased each other. When feeding, they scramble to eat. Why has it changed so much? Personally, I think: Although carp grew up in rivers and lakes, they are used to living without changing water for a long time. But just as people like clean homes, fish also like clean water. Clean water is not only "fresh air", but also there is no excrement in the pool. Of course the fish like it! Fish like to play very much! Sometimes they pounce on food, sometimes they hit down, and sometimes they chase each other in the water. But these are all swimming fish. Won't they "walk backwards"? Through observation, my answer is yes. Look at my koi fish. When the little guy swims forward, the ventral fin paddles backward, and the body and tail paddle left and right, creating a vortex to push the fish forward. So sometimes they can slide for a while with the help of the current. When swimming backwards, his ventral fin paddles forward, generating a driving force like that of rowing, and the fish naturally "retreats".
Homework help 65438+1Thursday, October 9th Weather: crisp autumn and pleasant scenery. Today, He Laoshi of our class took us to the campus to observe plants. The plant I choose is hydrangea, also known as dragon boat flower.
Hydrangea usually grows on the roadside, community, campus ... It is thirsty, and Sister Rain gives it water to drink.
It's cold, and the sun keeps it warm.
At night, it is lonely, and Brother Moon chats with it.
Hydrangea grows slowly in this environment.
Hydrangea generally has three colors, pink, light yellow and snow white.
Hydrangea has delicate flower bone buds, which are bright red and soft at first, and then gradually harden.
Hydrangea must have sunshine, water and soil where it grows.
I found that there are about 10-20 four-leaf clovers in a hydrangea, which is very strange! Its stems are tender and tender, and some are a little green, like a timid child.
Let me tell you a little knowledge! Hydrangea is a kind of hydrangea, which is native to China and Malaysia.
Friends! You also like this beautiful hydrangea! !
My family just raised a giant salamander, which looks like a lizard. I put it in an ecological bottle and live with loach.
The front of giant salamander is dark brown, but the back of giant salamander is different. The colors on the back are scarlet, gray and brown.
As fast as a brick, it filled the giant salamander's back.
Giant salamander breathes with its lungs, but every once in a while, giant salamander will jump out of the water to breathe, and then quickly dive into the water.
The giant salamander's limbs are short and fat, with 4 fingers on the forelimbs and 5 toes on the hind limbs, and no claws.
Two fingers (toes) are different in length.
My baby fish is very lively. It just loves to crawl. It thinks its limbs can be compared with the sucker of Parthenocissus tricuspidata. Every time he climbs up, he always falls down.
But it can climb out of the short bottle, and the reason why it can climb out is because of its tail.
Giant salamander is easy to catch in the water because its skin is too slippery compared with loach. If you stay in a place without water for a long time, your skin will become sticky, but it won't stick when you return to the water.
Its lively and active personality has also caused trouble for itself.
The morning after I bought the giant salamander, I went to the ecological bottle on the balcony to look for the giant salamander, and found that it was gone. I was in a hurry. I quickly told the news to my parents, and we all looked for giant salamander together.
Finally, my father found it in a pile of marble. At that time, the giant salamander was dying. Father quickly picked it up by hand, put it in an ecological bottle and slapped it on the back with his fingers. After a while, the giant salamander woke up slowly, and then it was alive and kicking in the ecological bottle.
Giant salamander's vitality is really strong! Do you think my giant salamander is cute or not? And a monkey. I like monkeys best. It is probably the cleverest of all animals.
When we approached them, a monkey stared at us with bright eyes.
It looks strange: the small nose is concave, the upturned mouth squeaks, and the hair is not only bright but also black and yellow.
Small ears stand upright, and two small claws scratch the scalp from time to time, which makes people laugh.
I took out a piece of bread and threw it. Unexpectedly, it did not answer. It just touched it with its claws first, then shrank back and looked at me with its eyes.
After a while, he grabbed the bread and wolfed it down. After eating, he looked at me imploringly, put his paw to what I wanted to eat, and I threw him another piece of candy.
It quickly peeled off the candy paper and put it in its mouth to chew.
After reading this composition, the cute image of the little monkey will be vividly displayed in front of us.
Therefore, this touching effect is the result of careful observation and detailed description by young authors from two aspects: static appearance and dynamic living habits.
When describing the appearance, the composition first summarizes the overall impression with the sentence "looks very strange", and then describes its sunken nose, protruding mouth, black and yellow coat color and scratching claws in turn.
After reading this, we will definitely have a good impression on the little monkey.
Then he changed a pen and wrote about the little monkey eating bread.
The author threw it a piece of bread. At first, the little monkey "missed" it, just "poked" it with his claws, looked at me with his eyes, and finally "wolfed down" it.
"This step-by-step description, written in detail, carefully written, produced a touching effect, but also the cute little monkey, truly displayed in people's faces.
I hope everyone can adopt it, thank you.
Observe the diary composition 400 words to observe what, time, topic and format are also clearly written. Ok, I will. ...
It's crisp in autumn and clear in Wan Li today.
I came to school early in the morning to see how the daffodils were doing.
When I came to the classroom, I found that Narcissus was like a different person, proudly facing the south station.
I quickly measured it. Wow, today's buds are 5 mm longer than yesterday's. I was overjoyed and even ate twice as much lunch as before! 165438+1Saturday, October 27th, sunny today is the weekend. I got up a little in the morning, but I saw narcissus wake up early and bask in the sun.
I walked lazily to the balcony and rummaged through the buds of daffodils, but nothing changed. Suddenly, I found another bud about half a centimeter on the branch near the root of the largest daffodil. I was so happy 1 that I only heard a squeak. When I saw it, I patted my chest and said, "Fortunately, I didn't break it."
165438+1October 28th I got up at 6 o'clock this morning on a sunny Sunday, because I was going to climb the mountain with my father.
Of course, I can't forget the first thing when I get up in the morning. As soon as I got up, I picked up a ruler and ran to Narcissus.
Unfortunately, how to make daffodils lazy today? I have no spirit at all.
I looked at the bottom of the jar. Oh, it turns out that Grandpa Sun came out wandering around these days and stole all the nutrients from the daffodils. No wonder I am listless. I looked at him helplessly and thought: I hope he can stand up again! 165438+1It's sunny on Tuesday, October 30th. Today's music class was really fun. I went home to watch daffodils humming a ditty.
Oh, my God, how did he fall to the ground? It turned out that my mother dropped him when she was hanging clothes. I picked him up and blamed my mother.
After I conditioned the daffodil roots, I put them in a small jar.
I looked at him and thought, the teacher is right. Raising flowers is much better than raising animals.
65438+February 1 Wednesday sunny will have a comprehensive practice class again tomorrow. I adjusted the daffodils, and in the process of readjustment, I found that many buds were still wrapped in small buds.
I wiped the thin ash on the daffodil, which looked very energetic, clean and attractive.
I think my daffodils will be the best in our class tomorrow.
Maybe no classmates will call him onion.
65438+Thursday, February 2 nd is fine. Today is the comprehensive practice day. I came to school happily with my daffodils in the morning. As soon as I entered the classroom, I found that my classmates had put plants on the south windowsill. There are many kinds: garlic, celery, radish, potatoes, and many flowers I can't name. It seems that the students have gained a lot. I held the daffodils high and strode to my position. "oh! How high! " Look at me on the surface, but I'm still complacent in my heart! I took out my ruler and looked at the daffodils. Oh, dear! The new bud has grown half a centimeter again! How happy I am! Saturday, February 4th, 65438 got up late this morning. I was going to do my homework at my classmate's house, but my mother wouldn't let me, so I had to observe the daffodils.
Oh! I was sick yesterday, but I recovered so quickly today! Hey! I have grown taller again. Did yesterday's rest lay a solid foundation for today? What a good mind! On Sunday, February 5, 65438, it was sunny. Today, the weather is getting cold. Narcissus was so cold that I had to take him to my father's office. At noon, he stretched again, bathed in sunshine, and looked happier than me! 65438+Wednesday, February 8th, sunny, tomorrow is the comprehensive practice day. I wonder what the students' plants will look like in a week. I will take good care of them and show them my true skill tomorrow. Wait and see, students, you will lose badly! I met Li Xiaojing on my way to school this morning. She wrapped daffodils in a convenient bag. Her daffodils are as tall as those in the convenient bag, and they have two flowers! Look at mine again. What a sharp contrast! But my daffodils are not without skills. You see, he also grew a flower bone flower, and a small branch on the right side of the flower bone flower also grew. So cute! 65438+February 10 It's sunny on Friday. The air is really good this morning. I ran for half an hour in the morning, eating bread and watching daffodils.
Because the weather is fine today, every branch of narcissus is separated, stretched and relaxed.
The flower bone has blossomed and has been climbing high. Today, it is half a centimeter taller than yesterday. It is really worth mentioning! 65438+ February Monday, 65438+ March sunny. What a big change today! The flower bone not only grows taller, but also grows small buds. What happiness! Wednesday 65438+February 14 Today is cloudy, but it has not affected the daffodils, but it has not changed. Unfortunately, I will take it to school tomorrow. I thought I would be envied by my classmates. Alas! All the plans fell through. Take your time. I hope there will be an accident tomorrow.
65438+ February 65438+Friday 07 sunny. It was very cold this morning. I'm really worried that daffodils will freeze to death.
When I came home at noon, as I expected, all the leaves fell. Oh, what a pity.
65438+February 18 It rained in Mao Mao today. I think it's a good opportunity. I put him in the rain.
I didn't think about him all the time because I went to school. This must have spoiled him. It's true. Anyway, there is no regret medicine in the world. On Sunday, February 20th, it snowed today and was frozen yesterday. Alas, it's hard luck! Jesus Christ. When will you pity this weak creature? 65438+February 2 1 Tuesday Sunny Today, God seems to understand what I said and immediately let out the sunshine.
I will take good care of him and change his water. Wait for his good news tomorrow! On Wednesday, February 22nd, 65438, the weather was fine. Today's narcissus is different from yesterday's. What's the problem? Hee hee hee hee, to tell the truth, he has grown another flower bone, hahahaha, it's simply great! On Thursday, March 4th, it was sunny. This morning, I had my first comprehensive practice class. Last semester, I planted daffodils, which were beautiful, with many flowers and lush foliage. This semester, I want to make great achievements in garlic.
Everything depends on this garlic tree.
Come on! March 1 1 Thursday Sunny Although I didn't have a comprehensive practice class today, I still want to observe him. His roots are tender and want to eat! He also has a small green bud in the upper part.
On Friday, March 25th, I haven't written an observation diary for more than a week. I can say that I am lazy, but I want to see him every day and write down his changes in a week.
How fragile and precious a life is.
He died, his roots rotted, but ...
There are more than three articles in my observation diary. The first article: My sister is an understanding, intelligent and beautiful girl. She is in grade five this year. My sister has always been an excellent student in the class, often helping her classmates, and the exam is among the best, almost perfect! In winter, I have a high fever because of a cold, so I can't go outside to make a snowman and have a snowball fight.
My sister knows that I really want to play outside.
So, on a Sunday, my sister came to pick me up and took me out for a walk.
The wind was blowing, and my sister's hands were red with cold, but my sister didn't shout tired, but bitter, and continued to walk on the path with the snow on my back. I saw the snowman around me. How cute! In order to meet my unreasonable demands, my sister made herself suffer, which made me particularly moved! My sister's math scores have always been the best in her grade. The math teacher often praises her. When the math teacher puts forward an application problem, she sometimes asks her sister to solve it. My sister's answer is not only completely correct, but also in several other ways. The teacher praised her again and again in surprise, and the students also cast envious eyes on her.
My sister is not only good at math, but also good at Chinese, English, physics, chemistry, art and sports.
I love my sister! Article 2: I am a careless child with two big round eyes, a small mouth and a red face. This is me.
Once, mom and dad were not at home.
It's time to go to school. I hurriedly put on my schoolbag and went to school.
However, when I got to school, I remembered that I didn't close the door! My heart is pounding like a rabbit jumping up and down in my heart, for fear that a thief will steal my computer.
When I came home in the afternoon, I found the door closed and thought the thief had stolen my computer.
I checked over and over again and found nothing missing.
I didn't know until I asked my neighbor that it was her aunt who closed the door. I thanked my aunt and went home with a red face.
Once, I finished my homework at night and was watching TV. My mother said to me, "Zhihua, look at your schoolbag and see if you have forgotten anything."
"I said," no.
"I didn't go to school until the next morning after washing my face and eating breakfast. I found myself wearing cotton slippers halfway, went home and changed my shoes, and hurried to school. When the school leader came to check my homework, I found that I didn't bring my homework, so I had to call my father to deliver it.
I don't know how to make my carelessness better, and when can I not be careless! Rule 3: You see, this is the person I have. She is 1.35 meters tall, with long black hair and small ears. Zhang Yuanyuan's face is like an apple ripened in April, and her big eyes are especially radiant.
There is also a cherry mouth under the small nose.
This person is me.
I have a wide range of hobbies, such as calligraphy, English and dancing.
I will dance for everyone in every class. Last year, I participated in the "Sunshine Youth" talent competition and won the first prize! However, my favorite is English.
My mother's colleague's children have been studying in Canada since childhood and can speak fluent English. I envy it.
Therefore, I must learn English well and study abroad in the future.
Of course, I also have many shortcomings.
Like carelessness, stubbornness, love to eat snacks and so on.
The biggest drawback is carelessness.
I remember a math exam, and I finished it by dividing three times five by two.
I didn't check, just sat in my seat and waited for class to end, thinking about how my father would reward me for getting full marks this time.
As a result, when I handed out the test paper the next day, I was dumbfounded and only got 87 points.
When I got home, I was severely criticized by my mother. I paid a heavy price for my carelessness.
This is me-a junior high school girl who has a wide range of interests but inevitably has small shortcomings.
The following diary is an observation diary that students were asked to write in 2005. It is published here, hoping to give some reference to these Protestant students.
The first group: Liu On the morning of March 8, 2005, the teacher left us an assignment to observe the growth of beans.
When I got home, I asked my grandmother to grab me a handful of soybeans, put them in a bowl, washed them three times, and then soaked them in water.
Grandma said, "It takes two hours to soak soybeans."
"After two hours, when I looked at soybeans again, it was really soaked. White fat soybeans are really beautiful! Today, March 9, 2005, the first thing I did after school was to ask my grandmother how to soak soybeans.
Grandma said, "The beans are in the bowl. Observe for yourself.
"So, I opened the cloth in the bowl and found that the soybeans changed a little, and the buds were a little bulging, but the bean skin had not yet emerged.
The old man said, "at this time tomorrow, soybeans will grow small buds."
March 2005 10, school was over. When I got home, I asked my grandmother, "Is the soybean sprouting?" Grandma said, "Today's buds are beautiful! Look! " At this time, I found that the soybean sprouts grew to about1mm.
Buds are sharp, just like children bulging their mouths.
I asked grandma how much soybeans can grow tomorrow. Grandma said, "Tomorrow the soybean will grow to about 2 or 3 millimeters.
"I asked my grandmother why the buds grow so slowly. Grandma said: bean sprouts grow slowly in the first three days, but fast in the fourth and fifth days.
March 2005 1 1 Today is Friday, and I have had bean sprouts for four days.
Come back from school today, bean sprouts have a new look.
The bean sprouts have grown to 1 cm.
The tip of the bud is very sharp, as thin as the tip of a living needle.
I asked my grandmother, "When will bean sprouts stop growing?" Grandma said: "When bean sprouts grow to a certain extent, they can be fried and eaten.
But you can keep an observation diary for a few days.
Today is Sunday.
The first thing when I come back from grandma's house in the morning is to see my raw bean sprouts.
I saw the bean sprouts grow again, about 2 cm.
Buds bend and grow close to beans.
Its roots and beans form a semicircle.
Then, it turned a corner and grew up.
The top of bean sprouts is still sharp. Grandma said, "It stands to reason that bean sprouts should be fried and eaten.
"The second group Wang Zicheng March 8, 2005 Today, the teacher asked us to soak beans.
As soon as the beans enter the water, the water turns yellow.
Slowly, the beans began to wrinkle.
After a period of time, wrinkles became more and more, and some even peeled off, like a double balloon. I peeled off the bean skin and saw the cracks on it.
On March 9, 2005, I got up in the morning and saw the beans drink all the water.
It looks a little dry on the surface, and the skin below is smooth and a little big. I added some water.
When I came back from school at noon, the beans were oval, brightly colored and wrinkle-free.
Each bean has a small bag.
Come back at night, there is a slightly bigger one.
2005-3- 10 I woke up this morning and found that the beans had not changed.
At noon, like pearls, a little pale.
The small bag bulged out again, so I changed the water for it.
When I came back in the afternoon, the beans were bigger, the skin was torn, and the packets were more obvious.
Mom said it would sprout tomorrow.
Beans have been sprouting from wrinkled old people, and watching them change day by day, I think it is really strange that beans grow like this.
March 2005 1 1 Yesterday, my mother covered the beans with a towel.
Nothing has changed this morning. At noon, I took a look. Wow! Every bean germinated and grew a small tip.
In the afternoon, the little tip becomes longer, like a fat comma. Thanks to my mother's method, it sprouted.
March 2005 12 When I woke up this morning, I saw many beans sprouting almost 1 cm.
At noon, the buds grow again.
Bean buds are very long, and bean buds are black. Are you sick? Mom couldn't say it right from the start.
March, 2005 13 I saw bean sprouts almost 1.5 cm this morning.
Although the water has been eaten up by beans.
However, towels can also add some water to beans.
Some buds are still curled, just like tadpoles.
On the morning of March 14, 2005, the sprouts of beans were 2 cm.
At noon, the beans turned blue and lost a lot of skin.
In the afternoon, I smelled it, alas! It tastes a little strange. My mom says this is the worst time. Some beans have not sprouted yet.
March 2005 15 today, the beans are all green.
It doesn't taste right either. I've been soaking beans for 7 days, and finally I know how beans grow.
Soak first, change the water once a day, and finally germinate.
You can make bean sprouts with soybeans and water, and carefully observe their daily changes. You can also directly soak Boat-fruited Sterculia (Chinese medicine) in hot water, observe its changes, and write an observation diary. Or you can directly search and copy the works about the observation diary online, but you'd better observe carefully before writing it yourself, so that you can write your own observation diary. Work hard, I am the parent of a third-grade child. My daughter just wrote an observation diary, which is the observed soybean. Please try it. Now we can make it ourselves. Not bad, but also a good way for us as parents to experience life. Please abide by it with your parents.
Please indicate the source? Observe my diary and write a composition of 300.
