Discovery composition in life

In daily study, work or life, everyone has the experience of writing a composition, so they are familiar with it. According to different genres, composition can be divided into narrative, expository, practical and argumentative. Do you know how to write a standardized composition? The following is my carefully arranged composition "Discoveries in Life". Welcome to read the collection.

Discoveries in Life Composition 1 On a sunny Sunday morning, my mother and I were drying clothes on the balcony.

Suddenly, my mother asked me, "Do you know how to turn salt water into fresh water?" I thought for a long time and didn't come up with it, so I said to my mother, "I don't know, how to turn salt water into fresh water?"

My mother looked at me and said with a smile, "I don't know, it doesn't matter, just watch." I saw my mother find a big basin, a small cup, plastic wrap, a small stone and some salt water. Mother began to demonstrate. She poured the salt water into the big basin, then stood the small cup in the middle of the big basin, covered it with plastic wrap, and pointed the small stones on the plastic wrap at the mouth of the small cup. Finally, my mother put the big basin covered with plastic wrap on the balcony where the sun can shine.

I couldn't figure out how this changed salt water into fresh water, so I asked my mother, "Will this work?" Mother said, "Wait and see."

After a while, I found that there was a lot less water in the big basin, but a lot of water in the small cup. I thought, "What's going on?" . Mother said, "You should observe carefully." I noticed that the plastic wrap was pressed down by pebbles, and there were small drops of water dripping down. My mother explained to me, "sunlight will turn water into steam." When the steam touches the cold plastic wrap, it will condense into small water droplets, which will flow down the sunken surface of the stone and fall into the cup below. Have you tasted the salt water in the cup? "

I took out my cup and tasted a spoonful of water. Sure enough, there is no salty taste at all.

I think it's amazing that mom knows so much! My mother read my mind and said, "Life is an endless book, waiting for you to find it!" " "

Discoveries in Life Composition 2 Discoveries in life have always thought that she is too old-fashioned and a little silly, but recent events have made me find that she and Lin are so beautiful and hardworking.

Lin Huqiong, a taciturn girl, may be because she looks ordinary and her clothes are not bright. Some boys scold her behind her back and give her nicknames, but she never cares and silently tolerates others' disrespect for her. Even if we tell her who is the person who speaks ill of her behind her back, she always says faintly and occasionally, "Ignore him." I'm surprised at this generosity.

She is a humble person. The school is equipped with sports equipment, with swings inside. We all like to play. Whenever there are a lot of people playing on the swing, she always doesn't want to squeeze and grab, but pushes the students in front of her behind. Other students play, and she plays quietly alone. Asked why, she always simply said, "Let them play first. Do you think I can still play now? " It is said that girls are stingy and will haggle over every ounce. This is the first time I have found such a modest girl.

She is also a girl who works hard. Originally, I always thought that the interest group was relaxed, even though we were in an English improvement class. Many students join interest groups with a free mind, but Lin is not. Every time, she carefully copied the words written by the teacher on the blackboard into her notebook. When other students go out to play, she silently recites words there without any interference from the outside world. Compared with her, I am really ashamed.

I found that in fact, each of us is like a dish. Some dishes are beautiful, but they don't want to eat after eating a few chopsticks, because the taste is not very good, and some are gone after eating a few chopsticks, because there is too little content. Although some dishes look ordinary and are often eaten, people will never get tired of eating them, such as Chinese cabbage. I think Lin should be Chinese cabbage, ordinary but delicious. Contact with her, let me learn to be a generous, humble and serious person.

Discoveries in Life Composition 3 Everyone will always make some new discoveries in life. I have one too. Do you want to know? Look down if you want to know!

Today, I was bored, so I went to the origami plane with my friends. I folded a pointed paper plane and a flat paper plane, but the flat paper plane always flies longer than the pointed paper plane, but shouldn't the pointed paper plane be able to separate air better? But why can't a flat-headed paper plane fly for a long time? I rushed home at once and said to my mother, "Mom, why does a pointed paper plane fly shorter than a flat paper plane?" Shouldn't it take longer than a flat-headed paper plane? ""I don't know, look it up online! "I immediately turned on my mobile phone and searched: Why does a flat-headed paper plane take longer than a pointed paper plane? After a while, I knew the answer.

It says: Just like a bow is round, a paper plane with a round head may be more suitable for flying. The center of gravity of a paper plane with a round head is particularly forward, so it flies more stably when the center of gravity is forward. Because the nose is too heavy, the plane is easy to stick to the ground, while the nose is too light, which is easy to cause the nose to stall. The nose of a flat plane is neither heavy nor heavy, so it flies steadily, while the nose of a pointed plane is very light, which leads to a light center of gravity, so it can't fly far. Also, because the nose of a flat-headed plane is wider, it can reduce the left-right swing of flight, and a pointed plane is unstable because of its small wind resistance and fast flight, which makes the flat-headed plane fly longer than a pointed plane.

This new discovery has given me more knowledge. I will definitely make more new discoveries in the future!

Discoveries in Life Composition 4 In life, science is the bridge of the new era, and it is with scientific inventions that advanced articles are produced. Life is full of laughter and laughter because of science. In an entertainment, a tiny experiment made me change my mind.

That day, I finished my homework early and was bored at home. I might as well go downstairs and play with my friends. I happened to meet my friend Yang Zhiqiao downstairs. Without saying anything, we ran to the rockery and started a one-on-one table tennis match. He said to me, "I'm ready. I'm going to serve, but don't go out before I get into the state." I replied to him, "Don't talk that big too early, lest you embarrass yourself." The words just fell and the ball flew like a missile. Because of my inattention, when the ball flew towards me, I was at a loss, and I was ready to hit back in a hurry, but I missed it. When the ping-pong ball landed, I stepped back and squashed it. I quickly said sorry, sorry! But he replied, "I'm in a good mood today, so I won't care about you." I thought to myself, if I hadn't stepped on your ball and owed you a favor, you would have ... I still warmly invited him to my house to rest.

Just as the water boiled and I fell into the bowl, a miracle happened! Table tennis fell into the water and gradually, gradually bulged. I ran to him in ecstasy and showed him the miracle. He was also surprised. The ball is bulging!

I wonder, turn on the computer and find out why. Suddenly, the table tennis shell is hollow. Once it is flat, it will expand when heated. This principle is called "expansion with heat and contraction with cold".

Ah! It seems that I was wrong before. I should not take science seriously. I should learn every subject well.

Discoveries in Life Composition 5 In life, science is everywhere, and sometimes it is likely to slip through your fingers. Whether we can catch it depends on whether we can find it. There are many things in life that deserve our attention. We should be good at discovering the little things in life. So: Science is all around us.

I remember one time, I tidied my room and dug out my exercise book. These books are jumbled up on my desk. I found the handwriting of pencils and ballpoint pens in these books. Blue, black and black are different in thickness and clarity. Why? I did a little experiment on a whim. I first asked my father about the structure of paper. It turns out that the main component of paper is fine fiber.

I also learned the composition of the refill and pen ink of two kinds of pens: the refill of a pencil is made of graphite and clay by stirring and firing; The pen and ink of ballpoint pen are made of oil and a special pigment. Then I found two kinds of paper: one is rough and the other is our ordinary exercise book. I drew a straight line on two pieces of paper with a pencil and a ballpoint pen, and found that both were very clear. I wiped it with my hand, and the ballpoint pen remained basically unchanged. On rough paper, two straight lines are very different; The straight line of pencil is like a row of neatly arranged ants, intermittent; The straight line of ballpoint pen is continuous, round, smooth and without burr, and there is little difference between the two straight lines in ordinary exercise books.

Finally, I found that when writing with a pencil, the pencil is attached to the surface of the paper. The rough paper is uneven, and the lead powder is only attached to the protruding place, leaving no trace on the concave surface, so the writing is intermittent. Smooth paper, lead powder is not easy to absorb, so only vague traces are left.

Look! This is the science of life. Many scientists discover science from ordinary things, then think deeply and come to a conclusion. Newton, for example, learned from an apple an extremely ordinary little thing that fell to the ground and discovered such a great achievement as "gravity". This shows that science is in our life, and we should be good at discovering it.

Discoveries in Life Composition 6 After going through youth and entering the flower season, the overview is dull and boring, and the mood is low, and I am rarely happy because I find beauty. Looking back suddenly, I found beauty everywhere in my life.

Beauty, at the corner.

If life is a journey, you and I are walkers. We may run to the goal for a belief when we set out, but in the process we ignore the scenery along the way. If you stop a little and look back at the road you have traveled, you may find how circuitous and wonderful it is.

Behind him, there is the east wind, the phoenix tree rustling in the drizzle, the swallow filling the south back of the West Building, and all the forgotten beauty is relative at the turning point.

Beauty lies in gazing.

When you stare at a blooming peony from beginning to end, when you quietly look at the magnificent ocean, when you carefully observe the pedestrians passing by on the road, you will find the beauty on the surface or inside, but if you look carefully, you will find it.

Hugo said that heaven is always in the eyes of children. I think beauty lies in a faint lightness. Because children's eyes are only novel and simple, it is beautiful to see the world with such crystal clear eyes. Looking at it is beauty.

Beauty, when broken.

The moment when the glass falls to the ground and breaks, the moment when the water splashes and blooms, and the moment when the fireworks start life, they are all beautiful. The leaves and stalks with traces of life are beautiful.

Beauty, what a clever woman she should be.

Maybe she is hidden in the mother who delivers milk at night, in the smile of grandma who comes to the door after you help take out the garbage, in the bud of a budding street tree, in the back seat of a speeding bicycle, and in the pen end of a book about this disease at the moment. ...

It turns out that beauty has been hidden in every corner. Maybe she is laughing at our carelessness now!

"You found it!"

"hmm."

Smile blooms and beauty appears. ...

Discoveries in Life Composition 7 Today, I want to tell you an interesting discovery. Guess what I'm gonna tell you? By the way, fish can't blink.

That day, my mother bought a carp to cook for us. In order to keep delicious, mother keeps carp in the pool. This carp seems to be in trouble, turning around in the pond as if to escape. In order to prevent it from escaping, I just stood there and watched it. I looked at it, and it shook its tail, spat bubbles and rested. I watched it for a while and found that the fish didn't blink. Not tired? Why not blink? I thought to myself. After a while, it was really boring, so I compared it. I opened my eyes wide and lost every game. Alas, am I worse than a fish? Why not blink? In order to solve this mystery, I decided to ask my mother. I asked my mother, but she couldn't tell. I guess I'll just have to check the information myself. I dug up all the encyclopedias and100,000 why did my mother buy it for me? I started reading encyclopedias first. I looked through it, but I couldn't find it. Suddenly I saw a picture with a group of small goldfish, so I quickly turned to that page. I thought to myself: great, I finally found it. But on closer inspection, it's not what I'm looking for. Then, I began to read "100,000 Why". Suddenly I saw a title: Ocean World. Finally found a piece of knowledge about fish. I rummaged, rummaged and rummaged, and finally found the answer I was looking for. Oh! It turns out that fish don't blink because they have no eyelids.

It turns out that nature has so many mysteries! It seems that we have to observe and think more in the future before we can explore the mysteries of nature.

Discoveries in life The so-called world is full of miracles. When it comes to important discoveries, people may think that scientists seem to have nothing to do with our lives. In fact, it is not difficult. As long as you do it with your heart, you can find intriguing scientific phenomena everywhere in your life.

We see the stars flashing, but it is not the brightness change of the stars themselves, but related to the atmosphere. The atmosphere separates us from the stars, guarding the image like a wall. When their density and transparency change, the stars we see standing on the ground will definitely feel the stars flashing.

I often yawn, which is a common occurrence for me, but why do people yawn? It turns out that when we feel tired, carbon dioxide has been produced in our bodies. When it is too much, our bodies will hum and emit carbon dioxide.

Whenever we go to a coffee shop for coffee, we will see the waiter put out the alcohol lamp with a lid. Why is this? Will he burn under the lid? After consulting the information, I finally understood the mystery. It turns out that fire needs oxygen to burn. As long as the lid is covered, it means that there is no oxygen in the fire. I am a basketball club. It's out. I really don't know. Shocking.

Another example is to put a burning ruler in a cup and immediately put the eggs on the cup. After a while, the egg dropped. That's great. Do you know why? As soon as the fire burns, the oxygen in the bottle is used up, and the air pressure enters the egg, so it falls.

Life is full of knowledge, there is science in life, and science is also in life. As long as you pay attention everywhere, any girl will solve them one by one.

Discovery in life There is a lot of love in life, which may come from relatives, friends or strangers ... People who give love are not great, but as long as they feel it with heart, we will find them as dazzling and beautiful as stars, and their love makes our life rich and wonderful.

I found maternal love in the needle and thread.

It was a cold winter, and I came home with my cold bicycle handle with my bare hands, and my hands were red with cold. Mother saw it and said with concern, "how could it be lost?" Why aren't my hands frozen on such a cold day? " Buy another pair tomorrow. "In the evening, I woke up and saw my mother knitting wool under the desk lamp in the dim light. I don't know what time it is. I thought: Why don't you go to bed at midnight? He turned over and fell asleep again. The next morning, a pair of furry new gloves were put on my pillow. At the table, I was eating breakfast carefully prepared by my mother. Dad came over and said softly, "Mom was afraid that you would freeze your hands at school today and didn't go to bed until after 2 o'clock last night. "Looking at more and more white hair on my mother's temples, I found that my mother's love can't wait until tomorrow.

I found the teacher's love in the desk.

I caught a cold these days, and a pile of paper towels piled up in my desk. I looked at them helplessly, alas! Clean after school! But after school, I left it behind. When I came home with a heavy head, I remembered it and secretly complained, "This is over! Let the old class with' cleanliness' see it tomorrow, and you must scold me! " The next morning, when I was eager to be the first to break into the classroom, I found that the old class had come to the classroom as usual and started a day's work. I went straight to my seat, but the "criminal evidence" was gone. Just when I was wondering, I saw my old classmate smile at me. "Are you better?" I understand everything. At that moment, I found that the old class, which has always been strict, is actually very gentle.

How's it going? I found a lot in my life, didn't I? Then, please find something in your life!

Discoveries in Life Composition 10 There is a magical sea abroad called the Dead Sea. Even those who can't swim won't drown in this sea. Why? According to scientists' research, this sea is rich in salt several times as much as other sea areas, which can make people float. Is salt water really buoyant?

Today, I did a small experiment on the buoyancy of salt water with questions. I want to see if the Dead Sea is floating because there is a lot of salt.

I have prepared the materials: raw eggs, tap water, large cup and half a cup of salt. First, put tap water into a big cup, where tap water represents the dead sea, and then gently put the eggs into a clear water cup. I held my breath and saw that the egg had not changed and was still immersed in fresh water. I did it back and forth several times, and it was the same result. This is, I guess: why don't eggs float? Is it heavy? I picked up the egg and was worried. 50 grams at most.

After a while, I put a few spoonfuls of salt in fresh water, stirred it with chopsticks, and then slowly put the eggs into the cup. I watched intently as the eggs rose slowly from the bottom of the cup and surfaced. I am ecstatic. But it makes me curious: the egg surfaced from the bottom of the cup, and it's incredible that the same egg has changed so much!

My curiosity increased. I put a few spoonfuls of salt in the mug and stirred it. I found that the egg surfaced in a larger area and almost jumped out of the cup. I'm surprised that the weight of eggs has become lighter. Eggs react too much to salt. I can't understand it.

After consulting the information, I suddenly realized that eggs have such a great reaction to salt because the density of salt water increases and the buoyancy increases, and eggs naturally float.

I got a lot of knowledge from this little experiment. Doing experiments is both interesting and informative. I will observe more and explore more in the future, and be a person with a conscience in life!

Discoveries in Life Composition 1 1 One noon, my cousin and I were playing outside. Suddenly, we saw a little thing, and our attention was focused on this little black dot. ......

My cousin and I climbed down to look at this little thing, and then took a closer look. It turned out to be a group of ants moving! We watched the ants move slowly, so we followed them to find out why. We walked away quietly so as not to disturb these small animals. At this time, a group of ants went into the hole. We looked at it and hid aside to wait for the ants to appear. Soon, the ants left with some food. We don't want to fall behind, keep moving forward. After walking for tens of meters, the ants stopped their actions. At this time, one of them stopped following.

After that, the ants walked to the trunk of a dead tree not far ahead, walked and walked, and finally reached their destination. Ants went into the hole one by one. By the time they fix the home decoration, we will have gone far. On the way home, my cousin and I both wondered: Why do ants move?

As soon as we got home, we consulted my "teacher"-encyclopedia. After a few minutes of searching, I got the final result:

Before the rain, due to the low air pressure, there was more water vapor in the air and the weather was sultry. After ants feel it, they feel that their home is low and easy to be flooded. If you move your home to higher ground, you won't be flooded. Oh, I see, so ants can feel the change of the weather. They are experts in weather forecast!

In winter, the grass turns yellow.

The winter storm came, and I was walking alone on the country road. My umbrella couldn't cover the raindrops the size of soybeans, and my shoulders were wet. Suddenly, I saw a touch of yellow-grass in the gray world. Under the attack of the storm, it has been wet by the rain, stuck to the ground, dying, and the ruthless storm pressed it down, turning the dream into a bubble and flying to the distant horizon.

In the rain, Parthenocissus tricuspidata, the wall of taupe meridians, is particularly conspicuous at this time. In this cold winter, I can't see its vitality at all, but the walls are full of twists and turns. The wind and rain didn't shake it at all, it seemed to blend in with the wall.

I have read books about tenacity.

In spring, the grass turns green again.

The spring rain came, and I walked alone on the country road. As the saying goes, "Spring rain is as expensive as oil." Facing the spring rain, I don't want to hide, and I'm too lazy to hide. I just want to enjoy the rural scenery. Suddenly, I saw the grass again. Now, it has taken off its yellow cotton-padded jacket and put on its green spring clothes. I thought it would be defeated by the storm, but I have been standing until now, and its dream has returned to its heart from the distant horizon.

The creeper on the wall is still there. Spring has come, and Parthenocissus tricuspidata has regained its former vitality. The tip of the knife is facing down, so it is evenly spread on the wall, without overlap or gap. I can't accurately describe the color of Parthenocissus tricuspidata in words, let's say it's green, but there seems to be a faint light green oozing out, and I can't accurately describe the connotation of Parthenocissus tricuspidata in words, let's say it's spiritual, and it seems a little cute. The spring rain magnified Parthenocissus tricuspidata. Although it is a wall, it slowly magnifies in front of the spring rain. Parthenocissus on the wall is still coquettish. Parthenocissus tricuspidata in spring is a beautiful painting.

I have read books about persistence.

Yes, only after experiencing the cold in winter can we understand how warm spring is.

Discovery in Life Composition 13 It's just dawn every day. When people are still sleeping in the warm bed, there is a rustling sound sweeping the floor outside the window. Who is sweeping the floor? It turned out to be a sanitation worker! A clean and tidy city is the result of the hard work of sanitation workers.

One day, I deliberately threw a bag of finished snacks on the ground, then quietly hid in the lush grass and stared at the bag with bated breath. After two or three minutes, an aunt came over with a broom and dustpan. She wore an orange vest, her lips trembled in the cold wind, her face was haggard, she was slightly hunched and thin, and she held the broom tightly. She looked around and swept away all the rubbish around her. Then, she went to find the garbage I threw. He frowned at first, then shook his head and swept the garbage in. I still say something in my mouth, as if to say, "Alas! Nowadays, children like to eat snacks and develop the bad habit of littering. " I want to say to my aunt, "aunt, I'm sorry, I don't want to throw garbage." I just want to know who makes our city so beautiful and clean! " "

When I got home, I couldn't wait to tell my mother everything I observed. I asked my mother, "Who is aunt?" Why does she clean the city every day? ""She is a sanitation worker. Mother replied, "It is their job to dress up the city. They are beauticians in this city. "

From now on, we must stop littering, make the world cleaner and make sanitation workers more relaxed. Let our beautician have a rest!

Discoveries in Life Composition 14 In life, everyone will have many discoveries. So, what did I find? Please let me tell you one by one.

Mom's hair turned black.

"Hey, who's this?" I cried as soon as I entered the door. "What, you don't recognize it?" Mother's face is rippling with a young smile. I reached forward and fiddled with my mother's hair. It's gone. A silver thread is missing. My mother's black hair came back again. Before I could speak, my mother smiled and said, "I just dyed my hair in the hairdressing shop. I used to see people dye my hair with colorful colors, but I just felt fresh. I didn't expect me to follow the fashion. " Mother said, combing her hair in the mirror. "Mom, come quickly." I rubbed her shoulder and said, "If you dress up again, others will treat me as your sister!" " ""little girl! " Mother touched my nose. Suddenly, our laughter filled the whole room.

Grandma is dressed in flowery clothes.

That day, grandma came home from outside and almost scared my parents. I saw her wearing a bright red shirt with a pattern. You know, grandma is an "antique" in my family. She always wears a gray and black suit on weekdays. She refused to wear the slightly brighter clothes that her mother bought for her, but today her attitude has changed 180 degrees. At this time, grandma also saw our surprise and quickly said, "Your grandfather will come tomorrow. I want him to see my change, so I will come." I see! We are all happy for grandma. How energetic grandma is in such clothes!

There are still many discoveries that make me think: what brought about these changes? Undoubtedly, it is the current good policies and the spring breeze of reform and opening up that have greatly improved people's living standards and gradually improved people's ideological understanding. I think this is the most valuable discovery of China people!

Discovery in life composition 15 "pa", another stone was kicked away by me, and I was bored walking down the street, and my heart was full of irritability. The monthly exam results came out, and my grades were very poor. The papers in all three subjects are red? It stung me so much that I even wanted to run out the door when the results were announced.

What a shame. I continued to walk uneasily, and the east wind whimpered and blew on my cheek like a knife. Suddenly, there was a "rumbling" sound from a hut on the side of the road, and I couldn't help looking in curiously. In the room, several people were busy in the pot waving big brooms. There is something dark green in the pot, which is tea.

It turned out to be a tea-frying workshop, so I couldn't help looking at them. Everyone works hard, and every frying is so meticulous. I can't help asking: why are you working so hard? Can't you fry less?

They are still frying seriously, and every movement seems to have exhausted their strength. Stir-fry every pot of tea resolutely, and sweat drips down. After a while, I saw them panting, but they didn't want to rest at all.

I stepped forward and asked, "Can't you fry less and save some energy?" One of the workers thought for a moment and said, "Making tea is a tedious job, and every link can't be neglected." Take fried tea as an example. Use less energy, fry less times, and do things seriously, and tea will become inferior. If the boss finds out, his salary will be lost! "

After listening to the sigh of the tea-frying worker, I couldn't help but freeze and think of my recent learning attitude: I always perfunctory the questions assigned by the math teacher; I only deal with the reading required by the Chinese teacher; I never recite the texts my English teacher asked me to recite ... as a result, my grades in this monthly exam plummeted. Isn't that why I don't take my studies seriously and my grades don't take me seriously?

I've learned that only by being diligent and earnest can we achieve the desired results. I want to face my study seriously and study hard. A failure is not terrible, just don't know why!

I strutted out of the teahouse and strode forward. The sun shines on me and illuminates my way forward.
