My discovery 200-word composition

In life, work and study, everyone has tried to write a composition. According to the characteristics of writing proposition, composition can be divided into propositional composition and non-propositional composition. Do you know how to write a good composition? The following is a 200-word composition of my survey results, which I helped you organize. Welcome to share.

I have climbed many mountains this holiday, including Genting Rock, Huwei Mountain, Dongping Mountain, Hongshan Mountain and so on. What impressed me the most was Dongping Mountain. When my father and I were driving in Dongping Mountain, I saw a sign with two S-shaped signs connected up and down. I asked my father who was driving, "What is this sign?" Dad said, "This is a sign of continuous turning."

I asked again, "What does this mean?" Dad replied, "It means that the road ahead should turn continuously." Suddenly I saw a mirror in front of me, so I asked my father, "What do you want with that mirror?" Dad said, "That's a convex mirror. You can see if there is a car coming around the corner. " The car drove to the top of the mountain, and I looked down the hill, ah! This is a reservoir. I asked my father again, "What's the use of the reservoir?" Dad said, "The reservoir can store water and irrigate farmland." Looking at Xiamen on the mountain is like watching a plane. Fields are like small pieces of paper; The house is like a building block; The road is like a tape. It's beautiful to see Xiamen on the mountain!

Today I will observe the magical boat-fruited Sterculia.

Boat-fruited Sterculia is oval with a small tip, like an apricot kernel. It is brown, wrinkled to the touch and looks like the face of a 70-year-old man.

Everyone said that boat-fruited Sterculia was the most interesting thing to put into the water, so I tried it and it happened. In the past ten minutes, the boat-fruited Sterculia has grown bigger and bigger, which is more than ten times that when it was not put into the water. There are small bubbles around the boat-fruited Sterculia, which looks particularly interesting. According to the teacher, Boat-fruited Sterculia uses these small bubbles to absorb water, which is really wonderful! Boat-fruited Sterculia in the water is like a blooming flower and those interesting jellyfish. It was really fun!

This is my discovery. What is your discovery?

I have discovered natural phenomena. As long as you observe them carefully, you will find many interesting mysteries.

Once, I went to a composition cram school in Hong Haier. During the break, He Laoshi walked over and sat down, saying that he would perform magic tricks for us. Magic? Where are the props? I'm not in a hurry to see the teacher. He first tore a piece of waste paper into pieces, then took out a ballpoint pen, rubbed it on his head several times, and then approached the paper, which jumped up one by one like an obedient child. I am very happy and surprised. I asked the teacher, "Why?" The teacher said, "This is an electrostatic phenomenon, which generates electricity by friction. Electricity is magnetic, so I sucked up the paper of light. " I see! The teacher took out the key and wiped it on his head a few times, then put it on a piece of paper and couldn't suck it up. "Why is this?" I asked the teacher. "Because the key is metal and the metal is a conductor, the static electricity generated by friction is conducted to the human body, so the pen tip has no electricity, while the ballpoint pen is plastic and the plastic is an insulator, which will not transmit electricity." Oh, I see. I finally understand.

There are many strange-looking phenomena in life, all of which have hidden mysteries. Today, I learned interesting knowledge.

On Sunday afternoon, my cousin and I were idle and played table tennis downstairs. I thought my cousin and I were fighting a protracted war, and you shot me. Who knows that when I wasn't looking, he gave the ball a hard board. This time, I won because the ball didn't touch my desk. But the ball was hit hard on the wall. What surprised me was why the ball didn't jump a few times when it landed, and the landing sound was different from the previous one. A series of questions swirled in my mind. I picked up the table tennis curiously, and there was a hole in it. I said, "This is the only table tennis. Anyway, let's wait until dad comes back! " "In the evening, dad came back. I told him what happened and gave him the ball. Without saying anything, dad poured boiling water into the bowl and put the ball in the bowl. After a while, the result stunned me, and the ball actually changed back to its original state. I asked my father what was going on. Dad said, "Because table tennis is hollow, it will expand when heated. "Although this is a small discovery, it tells us that there is learning everywhere.

My discovery 200-word composition 5 I have five small crabs at home. I feed them with water every day, and watch them play, and I find a strange phenomenon when I watch them. Crabs walk sideways.

Why do crabs walk sideways? I asked my parents, and they don't know. I found the answer in "100,000 Why".

It turns out that a crab lives in water, and its body is covered with a hard shell. A pair of claws and four pairs of feet are arranged on the left and right sides of its body. Paws are used to catch food and protect themselves, and four pairs of feet are used to walk and swim. The crab walks sideways because its joints can only move left and right, but can't bend and move back and forth. When a crab walks, it grabs the ground with one foot and pulls its heavy body with the other, so it moves bit by bit.

This is my discovery.

I have a little turtle, very cute.

I feed it every morning at school. Come back at night and change water for it. Hello. The tortoise swam happily in the water, sticking its head out of the water as if talking to me.

One day, when I came back from school, I found the turtle motionless. It didn't eat the food I fed in the morning. I thought it was dead. I hurried to find my mother. My mother looked at it and said with a smile, "The tortoise is not dead, it just hibernates." With this question, my mother and I looked up a lot of information on the Internet and found that turtles hibernate, and they are like snakes. Frogs are all the same They all hibernate in the soil. The temperature at which turtles hibernate is110 degrees. If it is higher than 10 degree, it will easily cause the tortoise to wake up and consume physical strength, which will lead to the decline of the tortoise's physique. If it is below 0 degrees, it will hurt in winter and even die. All winter, the tortoise hides its head, tail and limbs in its shell, closes its eyes, does not eat or drink, and does not move or have diarrhea. Through surfing the Internet, I found that my turtle wanted to hibernate. I want to prepare soil to help turtles hibernate.

On a sunny day, I was walking leisurely on the path, and a long string of ants caught my attention: some were big, some were small, some were dragging a white package under their stomachs, and some were still holding something in their mouths. Every ant looks flustered and goes all out. It turns out that they are moving.

Seeing this, I suddenly thought of a proverb: it will rain when ants move, and it will rain when spiders weave webs. After a while, the sky was overcast, thunder and lightning, and it rained cats and dogs. I am puzzled: how do ants know it will rain? I went to ask my father, who said, "Don't always rely on others, you can find the answer from books." After listening to my father's words, I picked up a copy of "100,000 Why". The book says, "Ants are small weathermen. Before it rains, the nest is particularly stuffy, and ants are very sensitive to temperature. Once the nest is particularly boring, the ants are ready to move. " They move to high places. Only by moving to high places can their homes not be flooded.

Although ants are small, they have given us a great education: there is knowledge everywhere in life. As long as you pay attention to observation, think seriously and be a caring person in life, you will find more mysteries.

I remember such an interesting thing when I was a child that I couldn't help laughing when I remembered it.

Once when I washed my hands, I found that the faucet was made up of tiny holes, and I thought: Such a small hole can't flow out as long as it is blocked by hand? The more I think about it, the more I feel that I am right, so I quickly prepare and want to verify my great discovery.

Because I was short at that time, I had to step on a stool to get to the sink. I'll get a small stool first, and then put on my mother's apron so as not to get my clothes wet. Now, the most important moment has come, and my great discovery is about to be announced.

I blocked the tap with my hand, and I am very proud. I think you can't get it out this time!

However, at this moment, I heard the sound of "rushing", and the water from the faucet sprayed out from the gap between my fingers.

Originally proud, I was washed all over by this sudden sound, like a "drowned rat", and I quickly changed my clothes in a panic.

I found that the 200-word composition is the largest in the world, with no surprises. In our colorful life, the same is true, and surprises often haunt us.

You see, I saw a pot of mimosa in the botanical garden, which is still very lush. Mimosa, as its name implies, since people call it Mimosa, there must be something magical about it. I looked left and right, and I didn't find anything magical! But I found that the small leaves of mimosa are arranged very neatly, and the grass stems meander upward like a small snake. Suddenly, a wind with sand blew over Guo. I quickly covered my eyes with my hand. When I opened my eyes, the mimosa actually closed, just like a shy little girl. Two seconds later, the mimosa slowly opened its leaves. What happened?

Later, I looked for the answer in my book. After reading it, I suddenly realized that mimosa is not really shy, but its leaves are very sensitive. Once something touches its leaves, the water in the leaves will darken and lose quickly. After a while, the stems will automatically replenish water, so that the mimosa can be closed. It turned out to be a mimosa, and this knowledge.

We must have a pair of eyes to discover the beauty of the world.

One morning, I found a cordate telosma with small flowers and purple petals, which was very lovely. After lunch at noon, I went to see cordate telosma and found that the petals were still closed, just like a shy little girl. This aroused my curiosity. In the evening, after dinner, I went to cordate telosma, looked at it carefully and smelled it. I found that cordate telosma opened its petals and floated a charming fragrance. A mosquito came, smelled the fragrance, but flew away. It turns out that the flowers of cordate telosma can be opened and closed like our palms. I know why this flower is called "cordate telosma". Because it is purple, it is night. "Lai Xiang" means the fragrance floating out. Together, it is the fragrance floating out at night, so it is called "cordate telosma".

Cordate telosma is not only beautiful, but also very tenacious in life.

I remember that one winter, the leaves of cordate telosma fell out, leaving only bare branches, which seemed to wither. I don't think it will survive next year. Unexpectedly, the next spring, cordate telosma grew delicate buds again. This reminds me of the truth that wildfires will not devour them, but they will grow taller again in the spring breeze.

Who doesn't like such beautiful and tenacious flowers with many colors?

I found a 200-word composition of 1 1 "Jasper adorns trees, and thousands of strands of moss hang down. I don't know who cut the thin leaves, and the spring breeze in February is like scissors. "Spring has come, and willows have sprouted, vying to become the overlord in the tree.

Curious, I followed my friends to the pond and saw thousands of willow branches fluttering in the wind, just like a girl singing by the river. Occasionally, a strong wind blows, and the girl who was singing just now instantly becomes a roaring lion. Some wicker gently brushed the water, and the small halo stirred up rippled around.

I looked down the wicker, and the uneven trunk was brown and white, and the markings on it were caused by wind and rain, and the willow still stood tall and straight.

Seeing this, I have a question in my heart: Why do wicker only grow by the river? I hurried home to check the information. Oh, it turns out that because the roots of willow trees are short and their ability to absorb water in the land is weak, they must grow on water and help them grow by absorbing nutrients in the water.

It turns out that the willow tree has its own secrets! Every child of ours should, like a willow, fully absorb knowledge and nutrition and grow healthily and vigorously under such superior conditions.

In the morning in Tomb-Sweeping Day, I was playing in the yard of my hometown. Suddenly a little spider fell on my head from the tree. I put the spider back in the tree and went to play.

At noon the next day, I came to the tree again. I saw this little spider crawling on the Internet. Gradually, the net becomes smaller and smaller. Huh? Is the spider eating its own web? Wow! It's true, spiders are really eating their own webs. This is a new discovery! I've only seen spiders weave webs, but I've never seen spiders eat them. With curiosity, I opened my eyes and observed carefully. When the spider finished his web, it stopped eating. I think it's even stranger. Will it be full? I was puzzled when my cousin came over. Seeing my ecstasy, he asked, "What are you looking at, brother?" Cousin smiled and said, "There is mucus on the spider web, which is used to catch insects. After a long time, the mucus will dry up, lose its viscosity, and can't stick to bugs. " Spiders have to eat non-sticky silk and highlight sticky silk to re-weave the web. "Some places don't eat because there is mucus on these websites, so they are kept.

Oh, I see. This made me understand the mystery of spiders eating the web.

I found a 200-word composition 13 Saturday morning in Wan Li, Wan Li. I went to the flower market with my parents.

This is my first time to go to the flower market. It turns out that the flower market is in a huge greenhouse. As soon as I entered the greenhouse gate, a damp smell came to my nose, and all kinds of plants appeared in front of me, some standing upright, like soldiers on guard; Some meat toots into a ball, like green pearls; Others are in the bud, like many colorful fudge.

Walking on, I found a cactus. Cactus is full of thorns, but I think it is round and lovely, so I can't help but reach out and touch it. Strange, cactus thorns don't prick your hands at all! I think this is a special cactus specially prepared for children.

Finally, my mother bought a pot of queen chrysanthemums. These green flowers are really beautiful. I hope it can bring fresh air to our home.

This visit to the flower market has taught me a lot about flowers. I like visiting the flower market.

One day after the rain, I went to the park to play. The air is full of the fragrance of the earth, and birds are chirping in the trees. All kinds of flowers smile, like handsome little girls. I was enjoying the beautiful scenery in the park when I came to the lotus pond unconsciously. Lotus leaves are flying in the wind. Suddenly I found crystal beads rolling back and forth on the lotus leaf, and I thought to myself: Why?

With this question, I quickly went home to check the information online. It turns out that there are many tiny protrusions on the surface of the lotus leaf-papillae. Observing these nipples with electron microscope, we can see that there are many small particles on the surface of each nipple. It is these wonderful protrusions that make the contact between the surface of the lotus leaf and the water droplets very limited, so the water droplets can not spread on the lotus leaf, nor can they penetrate into it, so they can only roll on the leaf surface.

After reading my introduction, you must also think it's amazing, right? What new discoveries have you made in your life?

My grandmother's home is in the countryside. There are fruit trees and vegetables in the open space in front of the door, and there is a river in front. The scenery here is beautiful and the air is fresh.

Once, my mother and I took a walk after dinner. As soon as we got to the river, we found a group of dragonflies flying head-on. They are all flying experts, just like highly skilled pilots. Dragonfly has a pair of big eyes on its head and a pair of transparent wings on its sides. They flap their wings and fly freely in the air, just like dancing elves. Not to mention how beautiful the scenery is.

But one thing is strange. They fly very low. They never thought flying would be so difficult, so I asked my mother what made dragonflies fly so low. Mother replied, "Because their wings are getting heavier and heavier." I still don't understand. Keep asking. Finally, it was found that it was because of the high humidity in the air that many small water droplets were attached to the dragonfly's wings, which made the dragonfly fly lower and lower. My mother also said a proverb: "If the dragonfly flies low, it will rain." Sure enough, after a while, raindrops fell in the sky.

This time I discovered the mystery of nature. I believe that as long as we pay attention to life, we will find more.
