Sliding slide of electrostatic reaction description composition on playground

1. Writing a composition on the slide in the playground One day, my sister and I made an appointment to finish our homework and go to the playground together. So, I did my homework while waiting for my sister to come. Finally, my sister came, and after lunch we went to the playground.

We first played the roller coaster slide, which is an inverted L-shaped slide, more than three meters high. When we looked at it, we thought it would fall vertically and break into patties. It started to slide, and I was very nervous. I closed my eyes tightly. As my body drops rapidly, I can't help screaming. By the time I opened my eyes, I had slipped to my head. If my mother were here, she would take a picture of me screaming with her camera. Finally, I found that I didn't fall into the meat pie, but I was lying like most people when I slipped down. Hehe, what a false alarm.

Next, we played the caterpillar slide, which is a cylindrical spiral slide with two floors high. Look down, I can't see my head. I was a little scared, but my courage overcame my fear. I still want to try. I sat on the slide and began to slide down. At first, the speed was not fast, but after several turns, the speed became faster and faster. My body began to slide left and right in the slide. Without cover, I would have flown out. I was a little dizzy when I came out, but I wanted to play again.

Finally, we played the wave slide. It is four meters high and has a peak every other meter. There are four peaks. When each mountain climbs uphill, you have to support it with your hands, and then rush to the second hillside by inertia, just like surfing in the water. I like the wave slide best.

Later, we played the Brave Tower here. It has 20 floors, and every two floors have an exit, which can lead to other places. We also played with building blocks, "Battle of Anti-aircraft Gun" and trampoline.

Because we haven't seen each other for a long time, we had a good time this time.

2. Slides of composition * * * [Slides of composition * * *] At three o'clock this afternoon, I pulled my mother out of bed and asked her to take me to Fengshan Park to write a composition on the slides of composition.

We set out with walnut dew, red bean cake and xylitol. At the foot of Fengshan Park, I got on before my mother parked the car.

How many people come to Fengshan Park to play today! There are old people, young people and children. I thought, "There must be a lot of people on the slide, too. If you don't get up quickly, there will be no fun. "

So, I rushed up. The slide was really crowded with children.

I ran up the slide, lined up at the slide and slid down one by one. When it was my turn, someone came up from below. I'm halfway, I can't get up or down. Later, I had to go out from the side.

When the children gradually dispersed, I sat and skated first, thinking it was too ordinary and meaningless. So I slipped sideways and got stuck in the middle of the road, so I had to turn around and sit and slide.

I wanted a * * *, so I squatted and slipped. It was steady at first, but almost somersaulted at the bottom. I leaned back hard and finally * * * sat on the cushion. I'm still sliding on my stomach, stuck like a bulldozer, and I have to hold hands hard to stand up when I get to the ground.

Today's skating is really * * *! I have an appointment with my mother to play once a week. w w w x I a o x u e 123。 Chief Operating Officer.

3. Imagine the composition of Happy Valley and write a slide tour of Happy Valley.

On June 1 day, my father and I went to Happy Valley to play.

On this day, the sun is like fire. As soon as I arrived at the gate of Happy Valley, I saw that there was already a sea of people here, and the children's faces bloomed with bright smiles. Happy Valley is a large-scale theme park in OCT, with nine major theme areas, including Adventure Mountain, Animation City, Spain Square, Happy Hour, Golden Town, Shangri-La Forest, Hurricane Bay, Sunshine Coast and Maya Water Park. Let's take the train to visit various theme areas first. My favorite is Maya Water Park, the third phase project of Happy Valley, which has a children's play pool. I like surfing, skiing and swimming here. What strikes me most is sitting on a UFO, which is actually a huge turntable. I feel like an alien sitting on it, flying between heaven and earth.

Happy Valley is so fun, it brings me infinite happiness and * * *.

4. I found the electrostatic component. It's sunny on Sunday afternoon. After finishing my homework, I'm going to the park with my mother.

My mother and I came to the park. I played on the swing and seesaw first, then on the slide ... I climbed up and down and played for a long time.

Somehow, when I slipped down the slide, I felt stung and felt as if I had been electrocuted. On my way home, I told my mother about this feeling. My mother smiled and said, "You will know later."

Mother brought a comb, a piece of paper and a pair of scissors from the bathroom. Mother cut the paper into small pieces with scissors, and then she picked up a comb and combed it quickly in her hair. Finally, she put the comb on those little pieces of paper, and those pieces of paper were actually sucked up.

I thought it was interesting, so I tried it according to the gourd painting gourd ladle. I didn't understand, so I asked my mother, "What's going on?" ? How to suck up the debris with a comb? "My mother told me:" At this time, because the comb and hair kept rubbing, static electricity was generated, so I sucked the paper. "

The phenomenon on the slide is also caused by friction, but the static force is too small to absorb your * * *, but it feels like * * * has been stabbed. "My mother looked at me with a grain of salt, and then said," You can also check online. "

I turned on the computer to inquire about "static electricity and triboelectric electricity", and it was as my mother said. Ha! I found static electricity! This is a wonderful world. If you have the heart, you will find more interesting novelty.

5. Electrostatic reaction of the slide When playing with the slide, there is friction between people's clothes and the slide, and the friction electrification is more obvious when the air is dry, especially when wearing woolen clothes.

Matter is made up of molecules, molecules are made up of atoms, and atoms are made up of negatively charged electrons and positively charged protons. In general, an atom has the same number of protons and electrons and is in a positive-negative balance, so it is uncharged.

Electrons surround the nucleus, and once they are forced out of orbit, they leave the original atom and invade other atoms B. Atom A is positively charged due to the lack of electrons, which is called cation, and atom B is negatively charged due to the increase of electrons, which is called anion. The reason for the uneven distribution of electrons is that electrons are out of orbit due to external forces, which include various energies (such as kinetic energy, potential energy, thermal energy, chemical energy, etc.). ). In daily life, any two objects with different materials will generate static electricity after contact out.

When two different objects touch each other, one object will lose some charges, for example, electrons will be transferred to the other object to make it positively charged, and the other object will get some remaining electrons to be negatively charged. If it is difficult to neutralize the charge in the separation process, the charge will accumulate and make the object electrostatic.

Therefore, when an object contacts and separates from other objects, it will be charged with static electricity. Usually peeling off a plastic film from an object is a typical "contact" electrification, and the static electricity generated by undressing in daily life is also a "contact" electrification.

Solids, liquids and even gases will be charged with static electricity due to contact. This is because gas is also composed of molecules and atoms. When air flows, molecules and atoms will also produce "contact" and electricity.

We all know friction electrification, but we seldom hear of contact electrification. Triboelectrification is essentially a process of contact and separation, resulting in the imbalance of positive and negative charges.

Friction is a process of continuous contact and separation. Therefore, triboelectrification is essentially contact electrification.

In daily life, all kinds of objects may generate static electricity due to movement or friction. Another common electrification is induction electrification.

When a charged object approaches an uncharged object, it will induce negative electricity and positive electricity at both ends without electrical conductor. In dry and windy autumn, we often encounter this phenomenon in our daily life: when we take off our clothes and sleep at night, we often hear a crackling sound in the dark, accompanied by blue light. When you meet and shake hands, as soon as your fingers touch each other, you will suddenly feel the tingling of your fingertips, which is shocking; When I get up in the morning to comb my hair, my hair tends to "float", and the more I manage it, the more chaotic it is. When you pull the door handle and turn on the tap, you will get an electric shock, and you will often make a "bang, bang" sound. This is static electricity generated in the human body. All the above phenomena are the result of the external "discharge" of static electricity in the body.

6. Water Park High-altitude Slide Composition Today is the weekend, and my parents took me to Dongqian Lake Water Park to play. I rushed into the swimming pool after checking the tickets. The water in the swimming pool is cool and suitable for swimming, but I just want to surf.

There are many slides in the swimming pool, the height is more than 20 meters, and the low is only two or three meters. Dad asked me to play the low slide first. I climbed the lowest slide, people slowly slid into the water, and some water splashed on my face. I feel that this slide is similar to the slide I played in the park, and it is not fun at all. So, I climbed a higher slide and stood on the platform to look down. "Wow, it's really high!" "I feel my legs are shaking and I dare not slide down. But when I heard my father say, "If other children would have slipped," I slipped without hesitation, because I didn't want to be laughed at by other children. I felt a whoosh and slipped into the water at once. The water hit my face, and I ate a few mouthfuls of water, and my eyes were a little sour. Later, I found that the higher I skate, the more dangerous I feel, but the more intense I surf, the more fun I feel. Dad always said, "Infinite scenery is at stake. "I finally understand this truth today.

7. How to write a composition on the slide? On this day, I was idle at home and begged my mother to take me out to play. My mother said to me, "It's snowing outside, so it's easy to catch a cold when you go out." After my repeated entreaties, my mother finally agreed to take me out to play in the snow, or in the old place-the hill in the moat park, where the snow is thick. Because we have played before, it has become an ice slide, so we can choose the slide at will, because there are three, and I have arrived, and every one slides. Each of the three ice slides has its own characteristics. The first slide slowly got stuck in the middle: I took it. After a sound, it was "cut!" The shoes are stuck in the snow. The second slide flipped quickly: I sat on the cardboard, "whoosh!" " "I slipped down at once, turned around halfway, then' overturned', and finally the wheel came down ... especially * * * was the third slide, and the speed was uneven: after I turned down, I went to the third slide and slipped when I stood on it, but I didn't sit on the cardboard and slipped with one foot. Hit people! Hey! " After several times, I only heard my screams: "Ah! ..... My poor head! " When you look at it again, you will shout, "Ah! Whose headless body is this! " It turned out that my head was stuck in the thick snow ... after I stood up, several adults came and stood laughing. I played for a while, and a few people came, and there was a junior high school student. We play the ice slide together, we play the train (that is, one person goes down first, one person follows ...), and I am the front of the car. "Hey!" I slipped at once, and a man rushed down behind me. With my agile skill, I leaned sideways and escaped the man's "flying kick". We played and before we knew it, it was six o'clock.

I went home with my mother.

Childhood on the slide

Every time she passes the slide, she always wants to see groups of children playing on it. Watching, she will sigh a few times, and then she will find someone, a little girl with two braids, a flowered skirt and bare feet!

She used to play on the slide, holding hands with children, whispering and singing on it. Although she seldom spent time with her parents, her childhood was still so happy because of the company of the slide. Every day, she goes skating. For her, skating as soon as possible brought her a lot of happiness!

However, childhood does not stop all the time, it is slowly disappearing, and after a few years, it will disappear without a trace. The little girl found that her childhood was almost gone, and it was useless to chase it.

She can't betray time, but she still has to grow up with time. The little girl became a big girl, and she was unhappy. She has no time to feel what true happiness is. Isn't there a saying that growth needs to be at the expense of happiness?

But she still misses her childhood, so every time she passes the slide, she has to stop and have a look!

Finally, she could not help it. She took off her shoes, ran from here to there, and slid from above to below. She hasn't been so happy for a long time. Only the children looked at her strangely: how did this big sister play crazier than us? She's an adult!

But she didn't care and continued to play like a child. She seemed to see the little girl, the little girl with pigtails, a flowered skirt and bare feet!

She is me! At the same time, she also represents many people!

8. First-year slide composition (5o words) takes me to Fengshan Park to play and write.

* * * * slides. We set out with walnut dew, red bean cake and xylitol. We came to the foot of Fengshan Park, and I rushed up before my mother parked the car. There are so many people coming to Fengshan Park to play today.

I sat on the mat. I still slide on my stomach. I pinned it down like a bulldozer. When I reached the ground, I had to hold my hand hard to stand up. Today's skating is really * * *! I make an appointment with my mother every week.
