Write a composition, observe and discover

1. Write a composition of observation and discovery. As long as you are good at observation, there are opportunities everywhere around you; As long as you are good at listening, you will always hear the weaker voices of those who are eager to help; As long as you have a kind heart, you won't work only for self-interest; As long as you are willing to extend your hand, there will always be a noble cause waiting for you to start.

Maybe everyone has seen a big basin full of water overflowing, but no one wants to think with their own knowledge. The volume of human body immersed in water is exactly equal to the volume of spilled water. Archimedes observed this phenomenon and found a simple method to calculate the volume of an object. Using this method, the volume of any irregular object can be calculated quickly.

Everyone knows that a hanging weight will swing back and forth regularly until it stops slowly due to air resistance. However, no one has ever thought about whether this phenomenon has other practical significance, and no one has ever thought about where this principle is applied in life. When Galileo was a teenager, he accidentally noticed that a clock hanging above Pisa Cathedral kept swinging from side to side, and the amplitude of swinging back and forth was very regular, from which the famous pendulum law was obtained. Until he was put into prison, the iron gate of the prison still could not stop his enthusiasm for research and exploration. He experimented with straw stalks in prison and finally found the relative strength of solid pipes and hollow pipes with the same diameter.

For many years, astronomers have observed a circular aperture around Saturn, and they all think that this is only an exception to the hypothesis of the law of planetary formation. Laplace also observed this phenomenon, but he did not regard this phenomenon as an exception. He believes that this is the only visible stage in the process of star formation, which is usually difficult to observe. He finally proved this view and added a bright stroke to the scientific history of star formation.

European sailors invariably imagined that there might be continents beyond the Atlantic Ocean, but no one ever took action to really explore them. And Columbus bravely led the fleet into the boundless unknown ocean and accidentally discovered the new continent.

Thousands of apples fell from trees and countless apples hit people's heads, as if to remind people to think about this phenomenon. Only when Newton saw the apple fall to the ground did he ask why, lost in thought. From this, he realized that the reason why the apple falls instead of falling upward or in other directions is based on the same reason. All the stars can operate normally in their respective orbits, and the molecules of the universe are constantly moving without colliding and tangling with each other.

Since the ancestor Adam and Eve, lightning has been shining in front of people, and thunder has been ringing in people's ears, but it has never awakened people's sleeping thoughts, and no one has ever realized that lightning has great energy. Only Franklin opened his eyes, pricked up his ears and looked up at the screaming crowd in the sky. He used an extremely simple experiment to prove to the world that lightning is the embodiment of a powerful and controllable force, which exists as widely as water and air in the universe.

2. How to write a composition observation and discovery 10 ant observation diary Today, I found an ant hole, under the corner next to my grandparents' house. I caught an ant, which is made up of three small sesame seeds.

The head and belly are black, like two bulging sesame seeds, and the middle is yellowish brown, like a shriveled sesame seed. The ant's body is about 0.5 cm long, and it is as bright as a layer of paint.

Ants have two tentacles on their heads, which often shake gently. The ant's mouth is like a little tiger pliers, which opens and closes one by one.

Ant's legs are thin and long, and there are six in one. Its legs are brown like its body, so it runs fast because it is long. I put a small piece of meat next to the ant hole, and an ant found it. It touched the meat and went back. After a while, it came to touch the meat and went back, and so on several times.

At this time, three ants came again, and they also came to eat meat. One of them went back to the cave. Soon, several ants lined up from the hole and went straight to the meat. Then there are more and more ants. An hour later, I came back to observe and found that the ants had transported the meat to the door of the cave, and the meat was covered with ants.

I spilled water on the ant hole. There used to be a pile of fine soil in the cave, but now it is wet and scattered. Then I saw many ants coming out. They kept pushing the soil out of the hole, and soon the hole was opened, and ants could go in and out at will.

Through this observation, I think ants are United, hardworking and fearless animals. Today, the immobile ant silkworm is still motionless. The leaves were swept gently, and it rolled out a long way.

In fact, its body is already stiff, but I don't want to accept this fact. Today I officially declare it dead, but I will keep it in a silkworm box for a day and throw it away tomorrow. At the same time, I also announced that an ant silkworm was missing, because I couldn't find its trace.

There is another one that is not good-looking, but this one, I prefer to understand as molting. The other four little silkworms are still moving, as if they are tireless.

A lot of their droppings were left on the napkin. These feces are pure black, much smaller than sand. With a light blow, these small particles ran away without a trace.

In order to observe, I often open the silkworm box and take a closer look with a magnifying glass. I wonder if they are afraid of this move, and to what extent? These days, the temperature is too low (for their lives), the surrounding sounds are noisy, and sometimes there are strong lights. I think these factors will affect their normal life. For them, they are stars now, and we are more like paparazzi in Hong Kong movies, constantly harassing and exploring their secrets.

Today's three second-instar silkworms are 6 mm long and their heads are black and small, so it is not easy to observe more detailed features. The chest is bigger and longer than the head and abdomen, and three pairs of claws grow here.

The abdomen has seven segments, the length is similar, and there are four pairs of abdomen feet longer than this. Which specific paragraphs remain to be further observed tomorrow. Now these young silkworms have been excreted, of course, they are eating, which can be judged from their leaves.

But silkworm leaves are not as much as I expected, and there are few gaps in the leaves I have eaten. Maybe it's that silkworms have a small appetite and can't eat more mulberry leaves.

I have been observing for 5 minutes, and three silkworms have been crawling from the back of mulberry leaves to the front, and then from the front to the back. Occasionally stay by the leaves, don't talk, just turn your head.

Big silkworms eat for a living, but these little silkworms spend their main time playing and having fun. I think of cats, dogs and even children. Isn't it always like this? Does this property also exist in young silkworms? Silkworm's life is only a short month, and they use these short days to enjoy the happiness of childhood, which is what we are willing to accept. The newly hatched goose was dripping with water and its coat color was not good, but its red feet aroused my interest.

The next day, I let these little guys out to feed. Their hair is dry, golden and soft. Although their feet are still too soft to stand up, they are all very lively. When they put down the ground, they jumped on the ground like wrestling. How funny! When the gosling sleeps, its small neck becomes shorter and its head covers it like velvet.

They wake up easily, with light footsteps, open their eyes to see, and then go to sleep without sound. More than ten days later, I just opened the lid of the goose cage and they were about to rush out. A gosling stood on another gosling and jumped out! Their hair began to turn white and their feet were not soft.

I ran for food. I put some rice on the plate first, with two big leaves in my hand. Their mouths are sipping rice, but their eyes are fixed on my leaves. Vegetable leaves seem more delicious than rice. A gosling jumped up, took a sip and fell down! Make me laugh.

These little guys are very human. As soon as I got home, they ran around my feet, very affectionate. I often chat with them, and sometimes they will answer! Therefore, I regard geese as my friends.

Monkeys 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. Mouse Doudou Doudou is not only a master climber, but also a delicious ghost.

Whenever you see him, he is always eating. For peas, "it is a pleasure to have delicious food." Just when I was admiring the way peas ate, I discovered a secret.

That day, I fed Doudou. Doudou didn't chew slowly, but bit the noodles into pieces and sent them to his mouth.

Observation and discovery in life 400 discoveries in life Are you still worried about the heat in summer? Are you still sad about the fallen leaves in autumn? Are you still afraid of cold in winter? Friends, don't be sad, don't be impatient, as long as you observe carefully in your life, you will find that Miss Chun has quietly come to our side.

Happy people in spring, you see, the streets and roadsides are full of busy and happy people, especially dazzling in the sun. At this time, Miss Chun soon planted the seeds of happiness in people's hearts.

In the field, children are flying kites happily. The design of the kite is a beautiful fairy. From a distance, it seems that Miss Chun is greeting everyone. The seeds of happiness grow fast! At school, a group of lively little girls are jumping rubber bands, and even boys are eager to try, not to mention how happy they are! "Apple trees …" When they beat, the seeds of happiness in everyone's heart are quietly growing, ah! Look, the seed has grown into a happy tree full of fruits! The flowers floating in the spring stroll along the country road, and I can't help but feel relaxed and happy when I look at the beautiful scenery of "the willow is dark and the flowers are bright, and the rain and snow are raining".

Suddenly, my eyes were attracted by what I saw. A small flower growing on a hillside stubbornly endured the wind and rain. Although this unknown flower was hit by the strong wind, it still didn't bow its head or give in. Its body is weak, but its life is tenacious.

I was deeply shocked, and Bing Xin's poem rang in my ear: the flower of success, people are only surprised by its current brilliance, but its bud is saturated with the source of struggle and full of blood and rain of sacrifice. I suddenly realized that perhaps the reason why flowers are so unyielding is because they want to bloom their most gorgeous colors in spring! With respect for Xiaohua, I continued to walk on the path and watched the spring rain fall on the ground. I remembered an ancient poem: the rain in the sky is crisp and crisp, but the grass color in the distance is close at hand.

I looked at the ground absently, only to find a grass trying to stretch its waist. "Wildfires can't be blown out, they grow taller in the spring breeze." Grass is common, common. Knowing that you can't be a towering tree, you made a grass, adding a touch of vitality, a green landscape and a green force to spring. Miss Chun's green skirt was given to her by the grass! The light rain in the mountain village gradually stopped and Grandfather Sun came out. Sister Rainbow will also come to play with Miss Chun.

Flowers and grass stand up straight and accept the sunshine after success! In my life, I found many interesting things and many beautiful people. Friend, it's spring. Have you noticed it in your life? .

4. The composition about observation and discovery, 600 words, should be meaningful, and it is best to write the discovery in observation by a great writer. I went out to play today and saw a puppy with fierce eyes. At that time, I was so afraid of dogs that I ran away. When the dog saw me run away, he chased me desperately for a long time, but I think the dog should have been dumped for a long time. Great! The dog is panting behind me! I wanted to run, but I thought, why should the dog run with you? Oh! The internet doesn't say, "the dog thinks you are weaker than it, so it wants to bully the weak." I kicked it, and the dog thought you were stronger than it, so he stepped back a few steps. Forget it, don't fight. I squatted underground. Unexpectedly, the dog ran away. What's going on here? It turned out that it thought I was going to throw stones at it. It was afraid, so it ran away. I have another discovery about ants: one day, I went out to play for a while, and there were dark clouds in the sky. This is not good. Didn't the weather forecast say it would rain today? I hurried home and found some ants climbing up the house downstairs. Why? I suddenly patted my head. The book doesn't say that ants climb high before it rains, and then find a hole to go in, so as not to be washed away by the rain. Another time, I put a pot of soil on the balcony. A few days later, I went to the balcony to get something and saw several weeds growing in the basin. I didn't put any seeds. How can weeds grow? It turns out that when I was digging, there were seeds in the soil, and the seeds germinated as soon as I watered them. The vitality of weeds is really strong. The findings in observation are not limited to these. As long as you are good at observing, there will be many discoveries, such as: why mimosa is closed, how rocks come from, why leaves turn green in autumn, why electricity can't be seen ... There are endless mysteries in nature. As long as we are good at observing, thinking hard and studying hard, we may become scientists like Li Siguang in the future!

I have been immersed in rainy days for the past few days. When I watched the rain, I found that butterflies were not afraid of rain. Why? Not only did I think of this problem.

In order to solve the mystery, as soon as the rain stopped, I went to catch butterflies to find out. When my hand touches the butterfly, I feel a layer of powder on my hand, which is very slippery. I held the butterfly in my hand and watched it again and again, but I didn't see why. I accidentally released the butterfly, and I left the powder on its wings. Butterflies without powder fly very low and slowly. What kind of powder is this? Why is there no pink butterfly flying very low and slow? I have more and more questions.

I brought a magnifying glass and caught a butterfly. I carefully observed the powder on its wings and found that the enlarged powder was distributed on the wings one by one. I thought: Is this the mystery that butterflies are not afraid of rain? Could this powder be a butterfly's "raincoat"? In order to prove my guess, I searched for the answer carefully. Finally, it's worth it, and I finally found the answer: the powder on the butterfly's wings is tiny scales. These scales are beautiful clothes for butterflies. They contain various pigments, which make butterflies look beautiful and shiny. Small scales are arranged on the roof like tiles, and they are of good quality and waterproof. But disposable, once damaged, it cannot be regenerated, so butterflies without scales can't be waterproof, and their wings can't fly high and fast when they are wet.

I have gained a lot of knowledge through this research. I think we primary school students should explore and discover more in peacetime.

5. Discovery in observation: How to write about plants During the winter vacation, my mother and I bought a pot of daffodils in the flower and bird market.

Do you know any other names of daffodils? I'll tell you what I don't know! It also has many names, such as Ling Boxian, Yulinglong, Jinyintai, Tiancong and Yayuan. Each of its names has a different interpretation.

Narcissus is like garlic before it germinates. You also have some tips when choosing whether it has flowers and bones. You can pinch its roots. If it is hard, it means there are flowers and bones in it, and vice versa. This is a little secret that the flower shop told me!

You take it home and put it in the water. After half a month, the leaves are flourishing and the flowers and bones are slowly growing. After the flowers bloom, the petals are as white as snow, and the flower heart is golden. It gives off a charming fragrance and makes people feel relaxed and happy, so people call it the gold and silver platform. At the same time, it is graceful in the water, and people call it Ling Boxian.

Although the life of daffodil is short, I like it very much. I suggest you also raise a pot of daffodils!

6. composition guidance: observation and discovery composition guidance-my discovery

There are always some new discoveries in our life. However, we seldom delve into the ins and outs of these new discoveries, so the discovery stops at the discovery itself, and we don't pay too much attention to the cause and effect of the discovery. This composition is to write a new discovery in my life clearly.

First, find the problems in life.

Life is the source of discovery. In daily life, we can only observe sleep, the cat's beard is very useful and so on. Others are about people, such as the sudden change of temper at the same table, the recent absence of quarrels between mom and dad, and so on. We should be good at choosing novel discoveries from life as writing materials.

Second, observe carefully.

If you have your own new discovery, you should carefully recall or re-observe the details related to it.

Third, I found that the narrative should be organized.

We know the whole process of the new discovery in detail. If readers want to know clearly the specific process of their discovery, they must organize it in the narrative. Write down step by step how you "found the problem", "explored the problem" and "solved the problem" in order of things. Generally speaking, it is what problems (reasons) I found, how I found them (process), and what I learned from them (results or reasons).

Fourth, the conclusion should be reasonable.

As long as you pay attention to life, discovery is easy. The key point is that for some profound, delusional and accidental discoveries, relying only on our own existing knowledge may not give a reasonable explanation, and sometimes even lead to misunderstanding. At this time, it is necessary to verify by consulting materials and asking teachers to ensure that the answers are scientific, true and reasonable. Discovery comes from our careful observation of life, and the experience gained from it fills our hearts with joy. A reasonable explanation of this discovery is the key to this composition. Remember: we found what is important, and how we found it is more important.

7. Observation and discovery in life 400 words of discovery in life

Floating flowers in spring

Walking on the country road, I can't help but feel relaxed and happy when I look at the beautiful scenery of "a bright future, rain and snow". Suddenly, my eyes were attracted by what I saw. A small flower growing on a hillside stubbornly endured the wind and rain. Although this unknown flower was hit by the strong wind, it still didn't bow its head or give in. Its body is weak, but its life is tenacious.

8. Write a composition about observing and discovering nature. Listen to nature in 400 words.

God gave human ears to let human beings hear voices, but I think the voice that you really listen to is your heart. Listen with your heart and feel with your heart. You will hear unexpected sounds.

flower

Grandma only grows azaleas. The azaleas were in full bloom when I went. When I was bored, I went to those pots of azaleas and leaned down to admire these beautiful flowers. Suddenly, I seem to hear a sound, gently, like the sound of insects chewing leaves. I was so surprised that I went to see another pot of azaleas. Oh, I heard a string of laughter like a silver bell. It is this potted flower that is laughing. I think only girls can laugh so beautifully! This is the initial throb of flowers. The flowers' initial laughter. This is the most beautiful music that nature has given flowers.

moon

I like listening to the moon because of Wang Zengqi's sentence "Warm a pot of wine on the moon". What a leisurely taste! One summer night, I was alone in the pavilion enjoying the moon and drinking. When the mood is leisurely, the moon will smile enviously. What does the moon look like when it smiles? In my imagination, I must be like a virtuous big sister, with pouting mouth, curved eyes and lively but solemn voice.

leaf

My favorite season is autumn. Whenever I walk into the park in late autumn, I always see beautiful scenery. The tree is very desolate, with a few scattered leaves hanging from the bare branches. I am a lonely person, but I don't feel sad to see such a scene. A leaf is falling and spinning leisurely. At the moment of touching the ground, I heard the sound of leaves. Is it despair of life? No, it's not. I clearly heard the leaves' longing and joy for a new life. I gently picked up this leaf and put it in my favorite book.

I don't think there is a more beautiful sound in the world than nature.

10. Observation Diary My Discovery Little Ant

In the afternoon, my friends and I went to the vegetable field to observe ants. I caught a very big ant and put it in a glass bottle, keeping it and observing it. Because of its huge size, it is named "Big Mac".

I found that the mouth of the little ant is different from ours. Its teeth are like a sharp machete. Maybe this machete can cut food better. The ant's body is divided into three parts, the first part is its head, the second part is its abdomen, and the third part is its tail. It has eight legs. Interestingly, it has two tentacles on its head. I wonder why it has two tentacles. So I ran back to the vegetable field to find out. At this moment, I found a little ant. It found a dead caterpillar in the field. It tried to move it, but it was too big to move it. At this time, it turned to look for its partner. It communicates with its partners with its tentacles. After a while, I saw the little ants lined up like a long black dragon and flocked to the caterpillar. Then, everyone struggled to move to the mouth of the cave together. I shouted excitedly to my mother: "I see, the tentacles of ants are used to summon companions, but they are used for communication."

I also learned a truth by observing small ants. Although ants are small, they have great unity. No matter what we do, we can succeed as long as Qi Xin works together.
