In study, work or life, when it comes to writing, everyone is certainly familiar with it. Writing is a verbal activity in which people express their feelings in written form. So have you ever studied composition? The following are five 300-word fourth-grade compositions I collected for you. Welcome to read the collection.

The winter vacation is coming, and the big exam is over. I am very excited.

I saw an experiment of "blowing a ball" in a book, and I found it very interesting, so I did it. I brought a wooden frame first. There is a wire across the wooden frame, and two ping-pong balls are hung on the wire. The distance between the two balls is about three or four centimeters. I kept reading, and the book said, "What happens when you blow between two balls?" I thought to myself: this question is too simple, a piece of cake. It's not up to you. Xiaoming next to him spoke. "Why?" I asked, puzzled. "I will know the answer when I finish this experiment."

The experiment began. I puffed up my cheeks, blew two balls hard and slammed them together. He burst out laughing. I said, "What are you laughing at? I just pushed too hard, so the two balls will hit each other. I'll try again. " This time, I took a deep breath, lowered my head, pursed my ass and blew hard. As a result, the two balls still touched. I said to myself, "It's strange, why did these two balls meet together instead of separating?" The reason is simple, because the pressure of flowing air is small and the pressure of surrounding air is high. In this way, we blow air between the two balls. When the air flows, the pressure is low and the air pressure on both sides is high, so we push the two balls in.

Yo! There are still many scientific reasons for a small experiment.

2008-11-12 time is like running water, and it slips away drop by drop, which contains many things. There are joys and sorrows, joys and sorrows, and many interesting things.

The happiest thing is the Spring Festival.

I get up early in the morning. Do you know what I do? Of course, get up and eat with jiaozi! I actually ate a "sugar dumpling". This is the proof that I will be sweet in the new year.

Watching lanterns, visiting the flower temple, carrying lanterns and setting off fireworks, the happiness of the day begins.

After dinner in jiaozi, my parents went to pay New Year greetings, and I played computer at home. I am grateful and satisfied to see my classmates' emails, because my classmates still remember me.

When my parents came back in the New Year, we went to the garden together. The scenery in the garden was so beautiful that I was fascinated. The fragrance on the garden stall is so delicious that I am very greedy. We played there all day and went home with great satisfaction.

The night in the countryside is quiet, but in the Spring Festival, the night in the countryside is very lively.

Children play games with lanterns in their hands, and adults rarely have leisure to get together.

How happy the New Year is!

Interesting things in winter vacation The winter vacation of 20xx has already begun. I want to arrange my holiday life. Besides my homework every day, I want to make this holiday meaningful.

I have a wish to go to the stadium outside the community to exercise 1 hour every day and finish my homework awake every day. Another biggest wish is to learn to ride a bike. I bought a bike for a while, but I stopped in the basement because I didn't have time to study at ordinary times.

The next day, after finishing my homework, I pushed my bike to a clearing and set off. My bike doesn't work at all. I'm nervous. The two of them don't cooperate well. This is what my father said to me after seeing it: "First, put the good car on, pedal hard, keep your eyes on the front, don't twist your body, and study hard." I tried again as my father said, and it was much better than before. I practiced many times, and slowly I got the gist. On the third and fourth days, I rode for more than an hour every day. I also believe that I will ride well this holiday.

This is also a very meaningful thing this winter vacation!

Although the winter vacation is only 20 days this year, I have done a lot of good things. There are countless meaningful things; Interesting things fill one basket after another ... but it is this that makes me unforgettable.

One day, my brother and I were both at my grandfather's house. Because my grandfather's house only had a computer, my brother and I had to take turns playing. But today I thought it was one hour per person according to the original regulations. Who knows, my brother actually said something that surprised me: "whoever grabs the computer will play!" " As soon as I heard this sentence, I suddenly got angry. Because my brother was playing, I was not qualified to rob him. I thought at that time: Let him play. Who knows, when I was playing, he actually came to rob me! I was angry at that time and thought he was unreasonable. I have no choice but to give him the computer. In hindsight, I let him go again and again, which only made him worse, so I can't let him go again, which will only hurt him.

Happy winter vacation, there is no need to make a fuss about a small matter, because "my winter vacation is my decision"! Besides, school will start soon, and I have to prepare things for school. How can you have the heart to find these "enemies"

I opened my eyes in the morning and realized that today is the first day of winter vacation! Get dressed quickly and prepare for the first day of winter vacation!

The beginning of winter vacation means the arrival of the new year and the arrival of lucky money. Of course, who knows how many lucky money there will be? However, the small account book in my heart seems to have begun to ponder how to use the money.

This money is not a small sum, and it can't be spent at all. What should I buy at an early age? And buy nothing less than a few hundred dollars! Where is the money? I was in trouble, and my pen, which was ready to start bookkeeping, was gradually put down.

After thinking about it, I finally thought of my own specialty. I need to pay for math and calligraphy. Remember this account! I quickly picked up my pen and wrote two strokes. In this way, my lucky money may be used up soon. Next, it is time for my petty bourgeoisie to control the money.

Petty bourgeoisie life is under my control. First of all, snacks cost more than RMB 100 a year, remember; Small things like daily necessities have to spend their own money, remember; Stationery bar, it's my account again, write it down ... everything is written down, read it, oh! There are some gifts for mom and dad. This new year, I will be twelve years old, learn to be sensible, think for my parents, hehe, be a good baby in the eyes of my parents!

I haven't got the lucky money yet, and I have taken care of nearly a penny. Haha, happy me! It doesn't matter, money is earned and spent (of course, I didn't earn it)!
