Fourth grade observation composition
No matter in school or in society, everyone will often come into contact with composition, which is a narrative method to express a theme through words after people's ideological consideration and language organization. There are many points for attention in composition. Are you sure you can write? The following is my carefully arranged observation composition for Grade 4 10. Welcome to read, I hope you will like it.

I have seen willow trees in the park.

This willow gives me the impression that its branches are thick and thick to the touch. Its branches are long and drooping, like a little girl's long braid. A breeze blew, and the willow branches danced with the wind, dancing like fairies, combing the hair of the willow branches. The spring rain is rushing down, and the willows look greener after the spring rain. Willow leaves are thin, tender and yellow-green.

You see, willow is really different from other trees. How beautiful!

You must be surprised, what is a leafy flower? Ye Hua Zi is also called bougainvillea, so you know! There is a bougainvillea in our school. Please listen to me together.

The bougainvillea bougainvillea stands by the unique overpass and gate, thinking of a conscientious guardian. It has a straight body and is afraid of bad people entering the campus. It carries sharp weapons and can protect itself at any time. A sharp weapon is a small spike growing on a branch. At the same time, there are purple flowers on the branches, only three petals, which are very beautiful, so they are named bougainvillea. There are patches of green leaves beside the small flowers, fluttering in the wind.

In the rainy season, it also straightened up to meet the beating of the storm. Even if the storm, it will not bow, but continue to smile, waiting for the arrival of sunny days.

On sunny days, it lives with its signature smile every day. Its smile is so charming that it makes people linger.

I like its smile very much. Every day when I go to school, I take a look. It's so cute and beautiful!

Ying Ying went out to look for food and came to the river. The water in the river was crystal clear, and Ying Ying accidentally fell into the water when he bent down to look in the mirror.

Sister Baiyun was playing hide-and-seek with her mother-in-law, when she suddenly found Ying Ying who had fallen into the river. Sister Baiyun was so anxious that she shouted, "Come and help! Little ant Ying Ying fell into the river! " It's very lively now. Cao Jie, Feng Popo and Ye Jie are all here. Sister Ye said, "I can be a boat for small ants." Sister Cao said, "I can be an ant's paddle." Grandma Feng said, "Let me help you." Then, the wind mother-in-law blew hard, blowing the leaves and grass to Ying Ying's side, and Ying Ying climbed into the boat with all her strength.

Ying Ying was saved. He said happily, "Thank you!"

I have a close relationship with my plant friend. Come with me to see and discover.

I put a small seed in the soil and give it a drink, a meal, a doctor and so on. Day after day, week after week, I waited and hoped! Finally broke ground and came out! I am very excited. I believe that as long as I work hard, persist and put my heart into it, I will definitely be rewarded!

During the long holiday, I patronized my happiness, but left it in the cold. When I came back, I saw it "with its head down", just like an "old woman" bent down with grief. My heart is breaking with anxiety. I am anxious to help him "bask in the sun", "drink water" and breathe fresh air, hoping for a miracle and continue to be friends with me.

A few days later, I was surprised to find that the stems and leaves were green, very slender and soft to the touch. Although they are just new life, they thrive in the breeze.

A gust of wind blew, and the faint fragrance of flowers came to the nose. Jinhua seems to be waving and smiling at me. A string, a string of show in front of me. How beautiful! That golden coat is like a flower fairy guarding the garden.

I read about it in a science book. Rapeseed can be used to extract oil after fruiting. It is a pure natural green plant, which is healthy to eat.

I am intoxicated with the beauty of rape, rape, you enjoy it! Let everyone see the wonderful things in your ordinary life!

This time, I wrote a short article about popular science. My observation object is a small animal, DD ant.

The ants we usually see are about 1d2cm in length, black or brown in body, with a pair of tentacles and six legs. The body is obviously divided into three parts: head, chest and abdomen.

Ants like to live in groups and walk away alone when looking for food. There are three kinds of ants in a nest: worker ants, male ants and female ants. We usually only see worker ants, whose main task is to find food. It's not easy to see females and males. You can't see the ants until they move. In the mighty ant moving team, the female ants are the ones with big bodies and wings, and the male ants are the ones with small bodies and wings. In the procession of ants moving, we can also see that there are many workers carrying white round things, that is, ant eggs.

The food that ants like to eat is sweets, such as sugar and bread crumbs. The situation of ants looking for food is very interesting. As long as you put the candy in the place where ants often haunt, wait patiently and observe carefully, you can see the whole process of ants looking for food. At first, ants crawled around aimlessly. When they are close to the candy you put, they will smell the sweetness and then slowly climb over. First, they will test the food with their legs to see if it reacts. If it doesn't respond, it will eat and try to drag it away. If the food is too big for it to drag, it will go back along the route to call its companion, and then you can find the ant's nest by careful observation. Soon after the ants enter the nest, several ants will come out and crawl in the direction of food along the original road. On the way, some ants will turn around and meet other ants on the road. They can talk with tentacles. Soon, many ants will come out of the nest to feed.

Ants are really an interesting little animal!

There is a little goldfish in my home. The whole body is white, only the head is a little red. Eyes are big and round, like two black pearls. When it swims in the water, its scales shine, so I named it "sparkling".

Today is perfect. I found it motionless in the water. I patted the fish tank, but it still didn't move. I was in a hurry and thought: Is this goldfish going to die? I quickly asked my mother, "Mom, why doesn't the little goldfish move?" Mom replied, "Maybe it's sleeping." After listening to my mother's words, I suddenly remembered that fish can't close their eyes, which made me worry for nothing!

I was about to go to bed when my father stopped me. My father asked, "Did you feed the goldfish today?" I said, "I don't want to feed it." Dad said seriously, "feed it quickly, or it will starve to death."

I walked listlessly to the fish tank and poured some fish food. Suddenly, I found a black slender thing falling from the tail under my shiny body. I want to know, what is that? Let me take a closer look. There's still a lot under this thing! In order to find out what this is, I took a long stick and touched it. I didn't expect it to break in two! I think this must be the excrement of goldfish!

Once, my father bought me a little turtle. I keep it in a fish tank and watch it whenever I have time. It has a sharp head with many patterns on it, a pair of black ruby eyes embedded on both sides, and a small mouth. It has three large hexagonal patterns on its back, and its limbs are short, but it is not slow to climb. It is dressed in armor and has limbs, just like a general dressed in armor and full of air.

Little turtle likes to bask in the sun. It's fun to bask in the sun. It bobs its head, sometimes turns around, sometimes rolls around in a jar, and its eyes shine like black gems. I stood up from time to time, but the terminal was unstable and fell off as soon as I stood up.

Once, I put a little tadpole in a fish tank, and the little turtle scratched four little paws desperately, as if to say, "Get out of my house!" " "The little tadpole ignored it, and the little turtle was angry. It pounced on the tadpole like lightning, and the tadpole fled everywhere. The little turtle bit the tail of the little tadpole and swallowed it in one gulp. Its black jewel-like eyes seem to say, "I'm still hungry." "

My little turtle is so cute.

We moved to the classroom on the first floor this semester. After class, my classmates and I went to catch ants.

We rushed out of the classroom with bottles and cans and ran to the big tree in front of the door, thick and strong, tall and big.

We started catching ants. I saw a big red ant with two tentacles crawling in a pit in a hurry. I put the bottle in front of it and waited for it to go in. But it didn't go in, it crawled in the opposite direction! I tried several times, but I still failed. I won't give up and keep scratching under the tree.

Ah! I finally caught one! Hey! Sorry, I'm so happy. Do you want to know how I caught it? Let me tell you slowly: I looked, ants like to climb on soft soil, so I paved a road for ants with soft soil, and ants came to the bottle along the road. I saw it climb to the edge of the bottle mouth, so I shoveled it in with the bottle mouth! I caught it.

The bell rang and we went back to the classroom.

As soon as I got home, I saw a small stone plate on the coffee table next to the sofa in the living room. There were a few pieces of "garlic" in it, and the lower body was soaked in clear water. I was surprised: "Is it nice to raise garlic in the living room?" Mom came, and when I said this, I couldn't help laughing.

"Silly boy, this is daffodils! This thing like garlic is his tuber. Don't look at it like this, it will look good when it grows leaves and flowers! Everyone calls it' Ling Boxian'! "

Listening to my mother's words, my heart is full of doubts: can such an ugly appearance become beautiful? It won't be the same as it is now, will it? With curiosity in my heart, I long for it to grow leaves and blossom early and have a good look at the beauty of "Ling Boxian".

After a few days, "garlic" really grew green leaves. Needless to say, it grew really fast, almost every day, and it didn't take long to grow to half a foot high. Look at it, it's green and long, just like a ribbon on a fairy. When the breeze blows, it wobbles, like a fairy dancing. I don't know when a few small buds appeared in the gap of the leaves. Gradually, the little bud burst into smiling faces, first one, then another, and finally everyone laughed. Look at that little white flower. Six round petals hold the moon like stars, protecting the golden petals in the center, and emitting a refreshing fragrance of flowers, which makes people feel relaxed and happy.

When daffodils are in bloom, spring comes. Who doesn't like the messenger of spring?

There are many interesting natural phenomena in our life. For example: soak mung beans in water and delicious bean sprouts will grow in a few days; Soak the leftover radish head in a bottle, and beautiful flowers will bloom after a while ... In order to increase this knowledge, I decided to observe the germination process of mung beans.

First, I put mung beans in a plate and soaked them all night. By the next morning, mung beans were full of water and became fat. Then I poured the water out of the plate, washed the fat mung beans, made them a quilt with a wet cloth and covered them tightly. When I came home from school in the afternoon, I uncovered the wet cloth and saw the baby mung bean's green coat spread out, and short buds grew in the cracks. Their buds are different, some are curved, some are straight, and the length is different. How interesting!

On the third and fourth day, I want to see the changes of mung beans every day, but there seems to be no obvious change in these two days, and even the bean sprouts are not so long. Grandma said it might be too cold, so I added some hot water to the plate. After another day, mung bean sprouts really grew a lot, about 1 cm long. In the next few days, I will add some hot water to my plate every day, and the mung bean sprouts will grow longer every day. On the ninth day, mung bean sprouts grew to 2.5 cm. Mom said that such long mung bean sprouts can be eaten. So, that night, they went to the table.

In the process of observing mung bean germination, I got many unexpected surprises and found many interesting phenomena. I found that observation is actually a happy thing!
