So I waited for an hour by the hot water kettle, just to wait for the suspect. It took me an hour to finally find the answer.
I saw the cork fall from its original position on the table, and then the steam came out. I thought, "This should have something to do with steam." I looked it up on the Internet and finally got the answer.
Answer: the steam stays in the kettle for too long and wants to escape, so the steam will push the cork out. I finally got a satisfactory answer. I danced to show off in front of my father.
Dad smiled and said, "Watt found out hundreds of years ago."
But it's good to find out for yourself.
This is my discovery story.
2. The composition of the first wonderful activity is about 400 words. When I was in the fifth grade, there was a school sports meeting to select athletes for township sports meetings. After several screenings, I was selected to represent my school in the1500m race.
From the day I was selected, I started running training under the guidance of my PE teacher. I arrive at school half an hour early every morning and run around the school playground for more than ten laps. Although I am exhausted and sweaty every time, I don't feel bitter at all in order to get a good ranking and win glory for my school.
The day of the competition finally came, and several players and I stood at the starting line with confidence. With a gunshot, we rushed out like arrows. I have been far ahead and trying to run forward, but when I run and run, I feel bored. My strength is getting stronger and stronger, but my legs are dragged like lead. I was really unwilling to see my classmates pass by me one by one, but I was in a hurry and couldn't help shaking to the end.
The game was over and I didn't get the position. When I saw the PE teacher, I hung my head in shame and waited for criticism. Unexpectedly, the teacher not only didn't criticize me, but also comforted me and said, "It doesn't matter if I didn't run well this time, mainly because I ran too hard at first, and then I got bored." Take a good exercise, and there will be another chance in the future. "
After listening to the teacher, I regained my confidence. I made up my mind to exercise well in the future, strive for good grades in the next exam, and don't let the teacher down.
Last night, a wonderful composition activity class spread ten miles, and now a flower city is scattered.
The old year added life to others, and Kangling was clean and tidy. Who created this great miracle? It's you, cleaner! Cleaner, I want to say thank you! You, thousands of unknown great people, will not only create miracles for everyone in this happy festival, but you have been fighting hard in the hot sun, cold nights, strong winds and heavy rains for many years.
It is you who let Luffy's sprinkler shed fresh dawn; It's you, waving a broom, wiping away the dirt in the city, making the city clean and radiant, and welcoming the first kiss in the morning in the East.
If someone asks: Do you feel hot? I think everyone will definitely say without hesitation: "Hot! Very hot! " Yes, in mid-June, we were surrounded by the summer craze! Especially at noon, the bustling community in the past is now deserted! People hide in air-conditioned rooms and enjoy themselves.
4. Remember a wonderful activity composition. Today is May Day. The three-day holiday at school can make me very happy, because before that, I made an appointment with Cui Zhuxiao to go to Zijingshan Park with some classmates on May 1 Sunday, but my parents didn't go.
At 10 in the morning, I arrived at the school gate on time to watch the entrance. In a short time, Li Mengru also arrived. 10 minutes later, several other students arrived one after another. When everyone was playing, I don't know who said, "Teacher Ma!" I turned my head and looked, oh, my God! No, it's okay, but it's shocking! Not far from us, Teacher Ma is talking to a young woman. Fortunately, they left after a while. I counted 1 1 individuals. Strangely, this activity was led by Cui, but up to now, I haven't even seen her shadow. With a wave of my hand, I said, "Let's go without waiting for her! Let's go! " At the right moment, Cui came, and our classmates 12 got on the No.80 bus happily.
In a short time, we arrived at the south gate of Zijingshan Park. We just made do and then went to the skating rink. "People who go skating raise their hands!" There are me, Cui, Zhao Lujun and Zhai Yijin. Oh ~ great. You two are away. What about the remaining eight people? I said, "Please, if you don't skate, where are you going?" They said, "Let's go find Bai. He said he wouldn't go with us and wait for us at the main entrance. " "Well, goodbye!"
After going in, we each paid 20 yuan money and went in to play.
I often come here to play, so I skate well. Plus Zhai Yijin is also good at skating, so we skate hand in hand. After skating for a while, we went back to our seats and wanted to pull Zhu Xiao and Zhao Wanjun to play together, but Zhao Wanjun said she didn't want to play. I was surprised: "What are you doing here if you don't play?" After asking for a long time, it turned out that she couldn't skate at all. I volunteered to say, "Let's teach you!" The words sound just fell and Zhai Yijin and Cui Zhu Xiao said tacitly: "Nothing, it's very simple! Come on! " Zhao Wanjun
5. How to write an active composition?
Writing activities refer to narrative interviews, interviews and some organized class and team activities as well as cultural and sports activities. Narrating a collective activity belongs to the narrative category and should be written in the order of things. When writing activities, we should pay attention to the following points:
1. Write all the links clearly.
Every activity has a process of development and change. Only by explaining this process clearly can readers feel immersive. The first thing to write an activity is to describe it completely, that is, to write clearly the time, place, people, content and process of the activity, so that people feel that the whole activity is complete. Generally speaking, the time, place and people of an activity will appear at the beginning of the article and be explained in a short sentence. For example, in "Remember a tug of war", the first paragraph of the article introduces "Today, our class will have a tug-of-war with Class 1, Grade 4. The competition place is the school playground. The rules of the competition adopt the best of three sets, with 20 people in each class. " In three sentences, the rules of the time, place and number of people in this activity are clearly explained. Another example is the beginning of "Remember a Math Contest": "It was a Saturday morning, and four classmates and I went to participate in the math contest held in the district. After the time, place and characters are explained clearly, the process of writing activities begins. The activity process is generally divided into three parts, before, during and after the activity, which are indispensable.
2. Write in a certain order.
There are many activities, so write them in a certain order. Generally, briefly explain the time, place, personnel and content of the activity first, and then write the process. Write the first content, then the second content, so that the article can be organized. Some activities can also be written in the order of changing places. For example, "ten minutes between classes" can be written in the order of changing places. You can write from the east of the playground. First, it writes about a table tennis table, and several students are playing. Then it writes about students climbing poles under the big tree on the right side of the table, and then it writes about the middle of the playground. Some students jump rubber bands and some students jump rope. Some kicked shuttlecock, and finally wrote to the west side of the playground, where several students were throwing sandbags.
3. Be detailed and appropriate.
The narrative process should also be detailed. When writing activities, many students write a "running account", from the beginning of the activity to the end of the activity. Reading such a composition is both boring and boring. In the process of writing activities, we don't write down all the contents very specifically, but choose the most exciting and profound places to write in detail, and the rest just need to skim. To make the main points concrete, it is necessary to write clearly what the characters did, how they did it, what they said and how they said it. In order to make the characters vivid and vivid, and the activity scene warm and touching, action description, language description and psychological description of the characters should be added. Please look at the following description:
It's our turn to play in the blink of an eye. My heart is pounding like a rabbit in my pocket. I secretly made up my mind that I must do my movements well and win glory for my class. We walked to the rostrum with neat steps and loud slogans. In this description, the author wrote about his feelings when he took the stage: nervous-"I feel like a rabbit, jumping straight"; Determination-"We must do our movements well and win glory for the class". The way of admission: "March with neat steps", "shout loud slogans" and walk to the rostrum with high spirits. Vivid image.
4. Point-surface combination.
It is not enough to describe the main characters in the activity, but also to write a good collective activity, so as to combine point with surface. For some performances and competitions, there are often many spectators besides the participants. Therefore, it is necessary to write not only the participants, but also the different reactions of the audience. For example, when describing the skipping competition, a young author described the audience like this:
At this time, the students sitting in the seats shouted for us: "Come on!" " Some students even stood up and cheered loudly. Listening to this deafening cry, we danced more and more vigorously.
5. the environment sets off.
In addition to describing the characters in the activity, we should also describe the relevant environment. For example, the scenery on the road, the movement of surrounding Woods and colorful flags, the layout of the meeting place and so on. This is not only concrete in content, but also lively and interesting in activities.
In short, you should learn to choose an activity that interests you and can attract your attention in detail among many activities. When writing activities, as long as the scenes of the activities are written in a certain order and combined with points and surfaces, they will be written well.
6. About the wonderful ending of the late-night action composition, the family fell asleep. I opened the movie Clouds and Ballads that I downloaded a long time ago. I was just browsing it, but I was deeply attracted at first sight and even read it at one go.
The hero and heroine in Where Are You Going didn't really impress me. The most touching thing is that the protagonist is waiting hard in the years of parting; Watching the pain torment his own Jindi; The pain of these two people is mixed with the pain of the heroine, which makes people feel deeply helpless and stinging. When fate plays tricks on people, have you ever thought about people's endurance? The actor was so absorbed in his performance that I couldn't help crying. I haven't cried for a long time. On a quiet night, I was immersed in the atmosphere created by this film. The feeling of crying is really comfortable and cozy!
The film ended in tragedy, which in my opinion is a perfect ending. Perhaps, the power of tragedy is touching! This move is far more intense and profound than comedy, and it is also more delicious! I hope to see more perfect tragedies!
Eyes covered with thin clouds spread their skirts and floated on the bright white water. Clouds and water stare at each other and condense into a blue planet. This is the swaying scene at the end of "Yun Shui Ballad". When the sun rises, the water rises and becomes a cloud. When the sun is weak, the cloud falls into the water. Wang Moshu has a poem: I will walk until the water checks my path and sit and watch Yun Qi.
7. A wonderful composition for campus activities is about 700 words. Thank you. Today is Wednesday. Under the arrangement of the school teacher, the students came to the public welfare activities from home with their own labor tools. Our class is responsible for cleaning the fences on both sides of the school.
At the teacher's command, the activity began. I saw Tong Xun's classmates take the bucket from home to the bathroom and carry a bucket full of water. Zequan picked up the rag brought from home, soaked it in a bucket, lifted it and wrung it dry, and wiped it hard on the dirty wall. Just as he was complacent, the stubborn little red dot stumped him. It turns out that these little red dot are little red pigments, which are difficult to wipe off with water. Zequan. Look, I saw Zequan bring a piece of green yarn, pour some detergent, hold green yarn in his left hand and a rag in his right hand, and begin to wipe out these stubborn little red dot. He squatted for a while, brushed it gently with his hand, then wiped it with a rag, and the whole tile became clean. ...
Look, not to be outdone, I tried my best to brush on the tiles. Seeing the tiles turn from dirty to white under my hands is as sweet as drinking honey. At this time, a long, winding crayon trace appeared in front of my eyes. I took a deep breath and decided to destroy it. I grabbed the rag with both hands and wiped it hard with my two thumbs, but only a little bit was wiped off. At this time, I found a green yarn and gently brushed it on the crayon line. The naughty crayon line suddenly disappeared without a trace, and I showed a happy smile ...
Happy times are always short. I looked at sweaty, flushed classmates and white walls, and my heart was full of a sense of accomplishment. ...
I have a glass in my heart, which contains large and small cups; Red and green things. That's my bittersweet recording chip. I randomly took a small piece from it and inserted it into the waves of memory. When I was a child, I was very playful. There is a small river near my school, which is especially clear and green. In summer, there are many fish and shrimps in the river, especially lobsters, which float slightly on the water or hide in the grass. Three. Looking at the air and joy of my friends, I also felt itchy and joined the shrimp team. Because I was too young, I accidentally stepped on it and fell into the river. I was flopping and shouting in the water-a teacher happened to pass by, and he hurried down the river beach, rushed into the water without taking off his clothes and dragged me ashore. I don't know why I was shocked by the water. I'm not moved-I was still so playful in primary school. I am tireless during the day, sleep deeply at night and often can't get up in the morning. In order not to be late, I often forget my lunch box in a hurry. At noon, my.
8. Colorful activity composition 600 words six? On the occasion of Children's Day, our school organized the first honest trade festival. Trade Festival is to sell new things and old things that are not needed to people in need, and then use the money to give love.
In order to sell more things in this activity, we gave our love to the greatest extent. Our head teacher, Mr. Hua, made overall arrangements and carefully planned to form different groups. There are four members in my group. In order to make the activities colorful, we have prepared for two weeks. Every day after school, we stay together to draw posters, make advertising billboards together, and then stick these things in conspicuous places in the school.
Looking forward to the stars and the moon finally made us look forward to the trading festival on Friday afternoon. Before President Su announced the start, many students couldn't wait to come to their booth and shout. The name of our shop is "Forest Garden", because we mainly focus on small bonsai and plants, plus some stationery and hair accessories, so the name is very suitable.
At first, we put the booth at the gate of Class 5 (2), but there are very few people here, so it is difficult to sell things. Through observation, there are many people on the first floor, which may sell better, so we decided to move the battlefield decisively. E79FA5E98193E58685E5EB931333433136631moved everything to the first floor.
No sooner had we set up the new booth than an aunt came. My classmates and I quickly introduced our plants to her: "This is mosquito repellent, this is mimosa, and this is …" My aunt asked us as soon as she heard that there was mosquito repellent. Can it really prevent mosquitoes? How to raise it? We introduced all the lessons we had done before, which really looked like a small businessman. Aunt nodded enviously to us, chose a pot and asked if we could make it cheaper. When we were excited, we thought that the first business was about to close, and we quickly said to our aunt, "You can take two pots and share 20 yuan money!" Aunt also readily agreed that our mood also changed with the change of customers, from worry to excitement.
The hardest part is actually in the beginning Since the first deal was reached, our mood has changed from nervous to relaxed, from passive response to active shouting, and business is very prosperous. I found that bonsai and small plants were very popular and sold out at once. Many customers wanted to place orders with us!
Besides bonsai, we sold many other things. On the whole, we have gained a lot. Then we donated all the proceeds except the expenses and tried our best to help those children in need. I wish them a wonderful and happy Children's Day with us!
In this rich and wonderful activity, let us know that we should dare to try anything and take responsibility. Also let us know that goods should be not only cheap, but also creative and attractive. More importantly, we must be honest in everything we do.
9. An essay "Wonderful Competition" and "Wonderful Competition"

When she gave me a stick, I was ready and eager to try. My opponent is very strong, but at this moment I heard the deafening cheers of my classmates. It was their cheers that gave me endless strength and courage and kept me going to the end. When Wang Xinyue took my baton, she ran as fast as she could, and the cheers, cheers and shouts outside the stadium were even more enthusiastic! Students' emotions are like a huge stone. But the opponent was too strong, and she fell to the second place. However, she didn't feel angry. She kept running and finally won the second place.
