Nature is like a kaleidoscope. Various natural phenomena appear around us from time to time. The most unforgettable thing for me is the shy secret of mimosa.
One day, my mother bought a pot of mimosa. It grew very lush. I liked it very much, but I also thought its name was strange. Is it because I was shy? Once, I touched its leaves with my hands. The moment I touched it, its leaves closed. I touched other leaves again, but the situation was exactly the same as before, the leaves were all closed. I turned the fan to the maximum wind to blow its leaves, and the leaves closed.
I thought: Why do the leaves of Mimosa close up? Is Mimosa as shy as a timid little girl? I asked my mother, and she said, "You can figure out the answer yourself. I believe Songsong is very smart." I walked to the pot of mimosa, picked off a leaf with my hand, and took a look. babble? Why is there so much water inside? I checked the information online again. After searching for a long time, I finally found out the reason: there is a lot of water in the leaves and petioles of Mimosa pudica. If you touch its leaves, the water in the leaves will flow to other places, so The leaves will curl upward. On the contrary, when the petiole is touched, the entire leaf will droop. Only then did I realize that Mimosa was not shy, but protected itself. I was very excited because I caught another small fish in the ocean of knowledge.
There are still many mysteries in the world waiting for us to uncover. I will study hard and grow up to explore more mysteries in nature. I discovered **'s secret essay 400 words.
I discovered the secret of the snail. One afternoon, the weather was very sultry. I was playing with my father's "darling" orchids on the balcony, and suddenly I saw a little snail climbing up a leaf.
"Are snails beneficial insects or pests?" "Why do they leave a long line when crawling?" "Where are the snail's nose and eyes?" This series of questions The question comes to my mind.
So I decided to do an experiment myself to clarify these issues.
"Are snails beneficial insects or pests?" I first placed cabbage, steamed buns, mosquitoes, etc. in front of the captured snails. They were probably hungry and crawled to their favorite food. I saw that the snails all chose cabbage leaves and ate them without smelling other food. In less than one meal, the snails ate up all the cabbage leaves. Now it can be concluded that snails are pests.
"Why does it leave a long line when it crawls?" For this question, I first used a leaf to lead the snail out, and then gently touched the bottom of the head with my hand. Unexpectedly, the head He immediately retracted, what should I do? I was a little discouraged. At this time, my father came to me and said to me: "Why, you are discouraged by such a trivial matter! Why do you still want to be a scientist when you grow up?" I was "excited" by my father and became excited again. .
An idea flashed through my mind.
"Yes, yes!" I shouted with my hands dancing on the ground.
I used a small stone to gently smash the snail's shell, took out the snail's body, and found upright objects by touching them with my hands. By flipping through books and looking up dictionaries, I knew Those are the snail's feet, and the long thin line is the snail's secretion, which helps the snail crawl.
"Where are the eyes and nose of the snail?" I followed the method in the previous part and put a cabbage leaf on the ground and caught another snail. This snail seemed to know my hard work and let it go. I saw its eyes, nose, the big tentacles and the small tentacles of the snail. The big tentacles are the eyes and the small tentacles are the nose.
Through this series of experiments, I have really benefited a lot! Not only did I discover the secret of the snail, I also understood a truth: if you want to invent something when you grow up, you must discover problems from an early age and learn to solve them. A 400-word essay on the little secrets in my heart
Deep in everyone’s heart, there are some little secrets.
I am no exception. I hide a little secret in my heart. I don’t want others to know it, but I feel extremely uncomfortable keeping it in my heart.
Even though this happened a few weeks ago, it's still fresh in my mind.
Whenever I think of this incident, I can't help but lower my head.
On Friday of that week, because my classmate He Yun asked me to go out to play, I did not finish the homework assigned by the teacher on the weekend (except for composition.
< p> Because children are very playful and enjoy playing with their classmates, so I went to play with them.Everyone had a great time and went home after 10 o'clock. , and because I went home to watch TV, I didn’t go to bed until 12 o’clock and didn’t get up until 11 o’clock in the morning, which disrupted my original plan to do my homework in the morning, so I thought again: “Isn’t there still another afternoon? Then finish all your homework in the afternoon!" So, I didn't do my homework.
While playing, I suddenly remembered a very important thing: I have to study Chinese in the afternoon. ? Do you want me to do my homework on Sunday afternoon? I have to tutor English on Sunday morning! At this time, I was as anxious as an ant on a hot pot. Teacher He from our class called me, so I just started talking. He lied and said that I was sick and couldn't come. After hearing this, Teacher He didn't pursue anything and asked me to see a doctor with concern. I was relieved.
In the afternoon, I successfully finished my homework, but I had to study English again tomorrow, so I had to finish my English homework first and stayed up until 12 o'clock.
"Ding bell" - the alarm clock rang. , it was already 8 o'clock in the morning, and I was already exhausted at that time. I had no time to study English. Besides, it would be shameful to go to study while yawning! I just stayed in bed and couldn't get up.
After more than 40 minutes, my mother urged me to go to tutoring. I said to my mother: "Mom, I went to bed late yesterday, plus I woke up late today, so I can't catch up with the English class, so I don't want to go.
" After hearing this, my mother said earnestly: "Hanhan, you didn't go to Chinese yesterday, and you won't go to English today, so you might as well go!" After hearing this, I just stayed in bed and couldn't get up. My mother had no choice, so she gave me her mobile phone and asked me to ask for leave from Teacher Jin.
"Hey, is this Teacher Jin? I want to ask for sick leave. I have a fever. < /p>
"I said pretentiously.
"Oh, yes, then you have to go to the hospital to see a doctor and pay more attention to seasonal changes.
" Teacher Jin said kindly.
After hearing this, I was stunned, my heart was boiling like water in a boiling pot, and my face was red, as if I was being grabbed.
When I think of this, my face gets hot, especially the kind and caring voices of Teacher He and Teacher Jin, which make my guilty heart unable to calm down for a long time... Let me tell you a secret in my heart. I have a little secret that I don’t want others to know, but it’s uncomfortable to keep it in my heart. I really want to find someone, just one person, to talk about the secret in my heart.
So I thought of you, because you are a good friend that I can trust. We talk about everything, don’t you think? In fact, this secret is not a big deal.
But I just didn’t dare to tell the teacher for fear of being punished. That was in fifth grade... That day, the sun was like fire, baking the asphalt in the cracks of the ground until it was soft. I sat in the classroom Here, it’s time to do recess exercises again. Although there are ten million reasons in my heart that I don’t want to do recess exercises, it’s better than being deducted points and punished for copying texts if I don’t do exercises. At this moment , I saw Yi Yang. He asked for leave today because he was sick and had stomachache.
I had an idea, why not follow suit? I just did it, I immediately bent down, covered my stomach, tried to make my eyebrows wrinkle into a knot on my eyes, opened my mouth, and shouted feebly: "Ouch..." After hearing this, the teacher quickly asked me with concern: " "Zeng Ming, what's wrong?" I said pretending: "My stomach hurts." "Wow! It worked.
" I was secretly happy.
Unexpectedly, my wishful thinking was wrong. The third class was physical education, which was one of my favorite classes. During class, I sat helplessly in the classroom and watched my classmates on the playground. I ran happily and played games, but I could only "depend on each other" with the book. I felt really bad. I really wished I could grow a pair of wings and fly to the playground, but there was no way. In order to prevent my lies from being exposed, I had no choice but to Patience, as the saying goes, "You can't have both shark's fin and bear's paw."
Unexpectedly, something even more embarrassing was yet to come. The fourth class was a Chinese class. Teacher He gave a very wonderful lecture. When I asked questions in class, I couldn’t help but want to speak, but I was afraid of the teacher and classmates. I had doubts, so I had to endure it and listen patiently to the answers of other students. Suddenly, Teacher He asked another question. Because this question was relatively lively, many students were puzzled, and our monitor was mentioned in the extracurricular book. The wonderful plot attracts me. Isn’t this just an opportunity for me to show off? I couldn't bear it anymore, just in case, I had to cover my stomach with one hand, humming in my mouth, and raised my other hand high. Teacher He called me to answer when the call was called, and I immediately said slowly After hearing the correct answer, Teacher He said happily: "You all must learn from Zeng Ming. He is still diligent in thinking even when he is sick. Let us applaud him.
" There was a burst of thunder in the classroom. There was such applause, but I felt as if the applause was hitting me in the face, which made me so embarrassed that I couldn't raise my head. I really wished I could sew it in and get in.
I finally made it to the end of school, and I seemed to have escaped from the classroom.
I have told you the secret in my heart without reservation. I don’t know what you think. Can you please tell me? ! Let me tell you a secret. A world without secrets is empty and lost.
We all have secrets in our hearts, and the secrets are all different. Do you want to know my secret? Then please read on! This secret has been buried deeply in my heart, and I never dare to tell others.
Now, I want to tell this secret, I want my parents to forgive me, and I want to say "I'm sorry" to my sister.
It was when I was in second grade. One day, my parents went out to work, and I was the only one at home, boredly watching TV that I couldn't understand.
After a while, my mouth felt dry, so I took a glass of pure water and drank it, but I still felt thirsty, so I thought of buying popsicles... Essay on the Secret of What I Discovered 400 words
I discovered the secret world of mimosa. Newton, a great scientist unparalleled by anyone, discovered gravity. Madame Curie, a strong woman in the world, discovered radium. She was known as the "mother of radium". Roentgen discovered X-ray, became the first Nobel Prize winner.
These discoveries all come from life. As long as we pay attention to the things around us, we will also make such discoveries.
I had a small appearance.
This little discovery made me happy, crazy, and excited. It also made me understand that a discovery is not difficult. The difficulty lies in asking more questions why.
One day, I was playing in the community. Suddenly, a small mimosa came into my eyes.
Curiosity prompted me to touch the mimosa.
This little mimosa collected its leaves in one go.
Why is this? I checked it out immediately after I got home.
I quickly turned on the computer and entered the words "Why is Mimosa shy?" on Baidu.
After a while, the answer came out.
It turns out that there is a relatively enlarged tissue at the base of the petiole of Mimosa pudica, called the "leaf pillow". The leaf pillow is full of water, often bulging, maintaining a lot of pressure, and The lower half has more pressure than the upper half.
When a finger touches the mimosa, the leaf is shaken, and the water in the cells in the lower part of the leaf pillow will immediately flow to the upper part and both sides, so the lower part of the leaf pillow sinks like a deflated ball. , the upper part swelled up like a fully inflated rubber ball, so that the petiole drooped and closed, like a shy girl.
But after a while, the lower part of the leaf pillow gradually filled with water, and the leaves opened again and returned to their original shape.
In fact, Mimosa not only droops its leaves when touched by hands, but also droops when it encounters rainy days or strong winds. This is its way of protecting itself from being destroyed by violent storms. .
It turns out that mimosa is not shy, but a way of self-protection.
There is also a lot of knowledge in plants, so we must study hard and read more extracurricular books in order to master more knowledge. Write an essay of more than 400 words about "I discovered a person's secret"
I remember when I read "Two Iron Balls Landed at the Same Time", I didn't believe what Galileo said: "The weight of an object depends on the time it takes for the object to land." It doesn't matter.
"But my classmates and I did many experiments where the paper balls fell to the ground at the same time, and I had to face reality.
After a long time, I thought about it and did another experiment, only to find that what Galileo said was not completely correct.
I found two pieces of paper of the same size, one was toilet paper and the other was cardboard. The cardboard was heavier than the toilet paper.
I threw it from upstairs, and the jammed paper hit the ground first. I did it again, and the result was the same.
Oh my God, is it possible that Galileo was wrong? I thought about it, if a piece of 100-gram paper and a piece of 1-gram paper were dropped from the same height together, the 100-gram paper would be heavier and could break through the resistance; while the 1-gram paper would not weigh enough and could only float down gently. .
Based on the results of the experiment, I feel that what Galileo said may not be entirely correct.
This is the secret I discovered. If you don’t believe it, you can do this experiment yourself. Write an essay of more than 400 words about "I discovered a person's secret"

After lunch, I took the initiative to wash the dishes.
The water was as cold as ice, and the oil in the bowl was slippery. I wiped it over and over again, and washed it again and again.
Alas, making money is not easy! I carefully took out the bowl. My hands were red from the cold and I couldn't feel anything at all. I really wanted to hold a hot water bottle and rest.

... My little secret 400-word essay
My little secret I have many, many little secrets.
There are a few of them that are hard for me to forget, so let’s talk about one below.
My mother is very strict with me, and I am not allowed to eat popsicles in summer.
But I also like to eat.
One day, my mother went out, and only my grandma and I were at home.
It was summer, summer vacation, and the weather was very hot.
There is no ice cream, no popsicles, anything at home, nothing to relieve the heat.
I whispered to my grandma: "Grandma, I'm so hot! Can you take me out to buy a popsicle to eat?" Grandma usually loves me the most. When she heard me say this, she was afraid that I was excited, so I agreed immediately.
My grandma and I came to the street. There were small shops and stalls everywhere on the street. My eyes were dazzled and I didn’t know which one to buy.
I had to ask grandma: "Grandma, which store should we go to buy popsicles?" Grandma pointed to a small store in the east and said, "Promise, let's go, let's go to that store.
p>
"My grandma and I came to the shop, wow! There are so many kinds of popsicles and ice cream in this freezer! I said to grandma: "Let's buy more popsicles and take them back. Mom and Dad can eat them when they come back.
" Grandma bought a dozen popsicles and put them in a bag to take back. I quickly took out one of them. Started eating a popsicle with mung bean paste.
I was so scared when I got home. What was I afraid of? I was afraid that my mother would severely criticize me if she found out that I had eaten popsicles.
After a while, my mother came back. She looked at me and suddenly asked: "Xu Nuo, did you eat the popsicle?" "I... didn't.
" I pretended to be fine.
Mom said: "Look, your mouth is still the color of popsicle water.
"Ah, my little secret is exposed.
Why didn’t I wipe my mouth clean? ...A composition about my own secret
I have a little secret. God knows it, the earth knows it, I know it, and you will know it soon too! Last summer my mother was on a business trip, so I carried her to the pet store near my home and bought some small bugs.
Because my mother is afraid of bugs, I took advantage of the two months when my mother was not at home to buy bugs and keep them at home.
When I got home, I put them in a box and gave them a new home. I didn’t let them go out and "misbehave" (for fear that they would eat the leaves of the flowers and plants raised by their mother).
One month has passed, two months have passed, and the little bug has slowly grown up under my careful feeding.
Just a few days before my mother came back, I fed them and found that the bugs ignored me and looked down upon the food I prepared for them.
Okay, if you don’t want to eat, I won’t feed them anymore. I will throw down the vegetable leaves and ignore them.
The next day, I accidentally discovered that the big leaves in a pot of flowers that my mother liked had been "killed" by bugs with a big hole.
No wonder they stopped eating the food I fed. It turned out that they really ran out and did bad things.
It’s over. Mom will be back in two days. How should I explain it? It must be another huge pain! What can we do? We have to find a way to avoid this "disaster".
I thought about it over and over again, and finally came up with a clever idea - to buy another pot of flowers similar to this one.
This way my mother won’t be able to tell, "Haha" stop laughing and leave immediately.
I ran to the flower shop downstairs and asked the boss: "Are there that kind of flower...that kind of...that..."
"My language was confusing, but The boss seemed to understand what I meant.
She took a pot of flowers. I took a closer look and I was delighted. It was not that variety.
The boss found a few more pots of flowers according to my description, but they were not the same! well! What should I do? By the way, ask Dad for help, Dad will definitely help me! I hurried home to communicate with my dad on the phone and reported the whole story, hoping that my dad would not only keep it a secret for me but also give me ideas to help me avoid my mother's "storm."
My father readily agreed. After get off work, he picked me up and went straight to the "Flower World". I searched in the flower greenhouses. Finally, with my father's help, I found the same variety and long leaves as my mother's pot. Very similar flowers.
My heart is finally at ease.
Two days later, my mother came back. When she saw the "fat and strong" flowers, she praised me and said, "I didn't expect that you took good care of the flowers. Well, I want to praise you."
" I breathed a sigh of relief.
The day before school started, I returned the little bug to the pet store.
This little secret has been "buried" in my heart for a long time. Now I tell you, you have to keep it a secret! I'd like to remind you again: if you don't want others to know, you have to do nothing yourself! ...
The secret in my heart Oh, don’t you know, I have a huge secret in my heart, which is the brush mark left on the wall of my aunt’s house.
The thing is like this, I remember one time, my sister was practicing calligraphy.
While my sister was cooking, I rushed forward desperately, took out a piece of rice paper, and grabbed the brush.
I was so anxious that I turned the brush upside down, and the upward brush tip suddenly touched the wall.
Ah! It's over, a big ink stain is left on the white wall.
At that time, I knew I had gotten into trouble, and my heart was pounding like a little rabbit.
I hurried upstairs and lay on the bed, thinking constantly in my mind: I want to be an honest child and should boldly admit my mistakes... but I always dare not speak.
When I heard my sister scream, my heart went cold.
The aunt is scolding the elder sister fiercely, and the elder sister is enduring the unfair injustice.
At that time, I felt very uncomfortable. I couldn’t wrongly accuse a good person like this! I don’t have the courage to admit it.
When I came to my aunt's house again, I found that my aunt had blocked the ink stains with a pot of spider plants.
Once again I wanted to open my mouth to admit my mistake, but I was really afraid of my mother’s reluctance, so I swallowed the words when they reached my lips.
A week later, I asked my aunt tentatively: "Auntie, who made this ink stain?" The aunt said angrily: "Which little villain doesn't know yet? Let me know." Yes, I must settle the score with him! "Yeah! Auntie still doesn't know who did it.
But I thought to myself, I’m not afraid of 10,000, I’m just afraid of the unexpected! If my aunt finds out, she will definitely not be able to spare me.
This is the secret in my heart, and it makes my conscience feel guilty.
