There are many discoveries in my memory. The most unforgettable thing is that at the age of 7, I found that fish can sleep with their eyes open.
That time, I couldn't sleep at night. I want to see my fish. As a result, I found the fish open and didn't blink. I thought the fish was dead, so I called my mother anxiously: "Mom, our fish is dead." Mom hurried to have a look and said with a smile, "Honey, the fish is not dead." I was puzzled and asked, "Why do fish keep their eyes open?" Mother replied, "Then solve the mystery yourself."
The next day, early in the morning, I went to Xinhua Bookstore to solve puzzles. I read "100,000 Why's" and "Encyclopedia", and with great effort, I finally found the answer. It turns out that fish don't have eyelids like us humans. It has no eyelids, so at night, we will see the fish motionless in the same place, as if it were dead, but actually sleeping. And when the fish sleeps, it doesn't sleep under the fish tank, but floats in the middle of the fish tank like a magical fish! Stay in one place. I excitedly told this wonderful question to my mother, who nodded repeatedly and praised me as a baby who loves to observe and discover. Hearing this sentence, my heart is sweeter than eating honey.
Through this observation, I understand that as long as you observe carefully, you will find many problems that have not been discovered before. I must study hard and explore more mysteries of nature.
One summer vacation, I returned to my hometown-Jinhua, Zhejiang. To see grandpa and grandma.
Grandpa and grandma were very happy when they arrived there. Grandpa immediately taught us two brothers "fish frog". I asked my grandfather, "I can't fish." Grandpa said, "I'll teach you." Grandpa put the bamboo pole down smoothly and moved it back and forth. I asked, "Grandpa, why are you moving bamboo poles around?" . Grandpa said, "otherwise it can't see." Why can't frogs see? Does it have poor eyesight?
I thought for a long time and couldn't figure it out, so I asked my uncle. Uncle said, "Frogs can't see because of their poor eyesight."
I did an experiment. I put the bamboo pole down smoothly and didn't shake it to see if I could catch a frog. Then I waited for more than half an hour ... I really couldn't wait any longer. Learn from grandpa, put down the bamboo pole smoothly, and then shake the bamboo pole? Move the bamboo pole. One, two, three, four, five, six ... caught a dozen frogs. I'm so happy!
It turns out that the frog's eyesight is really poor. It seems that there are many mysteries of nature waiting for us to uncover one by one.
The mystery of nature composition 3 at noon today, after lunch. Seeing that grandma took some leftovers to feed the ducks, I found a dozen bones of the fish I ate today. So, I ran to grandma and said to her:
"Grandma, there are fishbones in this duck food!" Grandma just squinted and smiled. He touched my head and said very kindly:
"Tim Tim, it doesn't matter." Duck has a solution. I'm thinking! So I decided to do a survey. I secretly ran to a big stone behind the duck restaurant (where ducks eat, where people eat is called canteen, and where ducks eat is called duck restaurant). Sneak up on ducks. The ducks didn't find me. They swaggered to the food bowl and competed for food. A duck is holding a green vegetable with a small thorn, and my eyes are fixed on the duck. Look, it secretes water from its flat mouth with a kind of saliva. As long as the ducks eat the food, the water will melt the thorns. Then, the duck can successfully complete the victory that he bravely grabbed. It turns out that ducks don't get their food for nothing. They have to compete with their relatives to get their food. Today, I understand that ducks use water in their mouths to make thorns disappear.
Unexpectedly, every place, place and thing in nature has a mystery!
I went to my aunt's house on Sunday. I saw a small white rabbit, blinking its big red eyes.
I ran over and looked at this cute little guy. It has snow-white fur, a little mottled. Just like cotton. Rabbit's ears are long, big and soft, and there is a lovely pink in white. The rabbit's short and small white tail, like a wool ball, is whiter and more fluffy than a wool ball. What fascinates me most is its ruby red eyes, bright and bright red. But why are the eyes of the white rabbit red?
My brother came to me and said, "You don't even know this. It must be because you lost your turtle and cried red! " "
"What's your answer!" Aunt also came over and smiled and said to me, "Don't listen to his nonsense. In fact, it is because different kinds of rabbits contain different pigment contents. The little gray rabbit is gray, and its eyes are gray. The little black rabbit is black. Its eyes are black. The white rabbit does not contain pigment varieties, so the hair is white and the eyeball is colorless, and the red we see is actually the color reflected by the blood in its eyeball. "
"oh! Thank you aunt! " I am very satisfied.
Nature has many mysteries!
Long ago, cats and mice were good friends and neighbors.
One day, news came from the sky that the Jade Emperor would select the twelve Chinese zodiac animals on a first-come-first-served basis. I am honored to be selected for the zodiac. The cat said to the mouse, "We have to get up early to register that day, but I like to sleep late.". What if I overslept? " The mouse said, "Don't worry, don't worry, I wake up early!" " You can sleep as long as you want. I'll call you as soon as I wake up and we'll go together. "The cat was very happy to hear this. He stroked his beard and said, "You are really my good friend. Thank you. "
On the morning of registration, the mouse woke up before dawn, but it only thought about its own business and forgot its good friend's cat. So I signed up myself.
As a result, the mouse was chosen as the first because it went early. Where is the cat? I got up late because I went to bed late. When it arrived, twelve animals had been selected.
When the cat was not chosen, it was so angry that it "meowed" and called the mouse disloyal. It vowed to punish the mouse. I saw it jump up and pounce on the mouse. How sharp the cat's claws are, but the mouse knows very well that it runs away.
From then on, when the cat saw the mouse, it would eat it, so the mouse had to run away desperately. This is still the case until now.
As we all know, insects can eat plants and destroy them. But you know what? There is a plant that can eat insects, such as Nepenthes and Nepenthes.
This morning, my mother bought a bag of Nepenthes seeds and a bag of Nepenthes seeds from the market. I planted these seeds in the soil, watered and fertilized them every day, and soon they grew out.
One day after school, I found many dead bees lying motionless in the pitcher plant, with a lot of liquid on it. I was thinking, aren't bees here to collect honey? How did he die? I couldn't understand it, so I took out "100 thousand whys" to find it. I found a viscous liquid called digestive juice in pitcher plants. This liquid will give off bursts of fragrance and attract insects. When the bug falls into the bottle, it will be stuck by mucus and then digested by digestive juice, leaving a corpse.
Bottle grass looks like a flower and attracts nectar-sucking insects. When the insects have not stood firm, they fall into the bottom of the bottle. Finally, they slowly absorb the insects like pitcher plants.
I really didn't expect that there are plants that can eat insects in this world before. Now that I have done it myself, I finally have a personal experience.
As long as we are good at observing, we will discover the mysteries of nature.
When we pass by a small canal and see the garbage beside the canal, we guess, if we are green trees, flowers, flowers are people, grass and trees are people, how will we feel if they bury us under the garbage? We can change our minds. If plants could talk, they would certainly advise people not to destroy the environment. In fact, we are one of them. Everyone should care for each other, help each other and care for plants.
I respect some people who look down on scavengers and say they are unsanitary. In fact, I think people who pick up garbage have an innate quality, because they know that the garbage they pick up has two benefits for them: one is to sell garbage to make money, and the other is to protect the environment. In fact, cleaners also want people to breathe fresh air every day and have a good body. So we should thank the garbage collectors, who not only bring us health, but also let us breathe the breath of nature.
Every bit of environmental protection life has environmental protection. We should start from the small things around us, protect the earth and protect our homes.
The Mystery of Nature Composition 8 Nature has its own way of life and its secrets to avoid disasters.
It was summer, and I went camping at the seaside with the tour guide group. We suddenly saw a group of carnivorous birds reaching out to a little turtle.
This is what most people agree to extend a "helping hand" to the little turtle. But the guide's words made us quite angry. He said, "Whatever!" "At last, the tour guide was persuaded by us.
We picked up the turtle and put it into the sea. Our hats were pecked away by carnivores. Only then did we know that we had made a serious mistake. The little turtle turned out to be a "scout" When it is in danger, it will draw its head back. This is a dangerous signal for other small turtles in the turtle nest. But we put the little turtle back into the sea, so other little turtles received the wrong "safety" signal. Get them out of the nest. This is the baby turtles coming out one by one. Suddenly, a lot of carnivorous birds flew in the sky, and the little turtles were taken away by carnivorous birds one by one. Although we worked hard to save dozens of them, more than 20 of them were taken away by carnivorous birds, and we felt very guilty.
This incident tells us not to stop animal behavior, not to hurt animals, and of course not to change or destroy the ecological environment at will. Otherwise, if we use human thinking to change the survival rules of animals, it will be counterproductive.
Today, my mother bought a bag of kiwifruit saliva, and I want to eat it right away. As soon as I got it, I felt that the kiwifruit was hard and not ripe! Looks like we have to throw it away. Grandma knew, and couldn't help laughing. I said, "The kiwi is not ripe yet, laugh!" After listening, grandma said to me confidently, "Go and get an apple and a convenient bag and watch grandma do magic for you."
I did as grandma said, and took some apples and a convenient bag. Grandma put kiwi fruit and some apples in the bag and mysteriously said to me, "this is a magic box full of magical power." The kiwifruit in the box will change magically in two days, wait and see! " Say that finish, grandma tied the bag tightly. A few days later, when my grandmother told me that I could open the convenient bag, I couldn't wait to pick up the kiwi and press it. Really soft!
Why is this? I think it's strange. Under the guidance of my mother, I looked it up online. It turns out that apples also have substances that can make fruits mature. This substance is called ethylene, which can play a role in ripening. Apples can not only ripen kiwifruit, but also ripen tomatoes ripened by bananas, pears, kiwifruit and other fruits.
Nature is really amazing! Around us, we can always see many surprises it brings us. Let's observe carefully and explore the mysteries of nature!
The Mystery of Nature Composition 10 Nature is like an impenetrable encyclopedia. Today, I read this thick book of nature with my notebook and crayons, and made notes on nature to explore its mystery.
We came to Huanglong Cave and met Ophiopogon japonicus for the first time. I stretched out my hand and touched it. Wow, its surface is really rough. When I look carefully, the color is dark green and the shape of the leaves is very thin. Ophiopogon japonicus really looks like green hair.
Then, we came to the edge of the trees at the foot of Baoshi Mountain and met the "octagonal gold plate". When I take a closer look, it really looks like a dragon's paw. I counted it carefully, and it turned out that the octagonal gold plate had seven or nine angles instead of eight.
Then, we climbed halfway up the mountain and met February orchid, a purple flower with four petals, which is very delicate and beautiful. Teacher Ma said that it also has a name called Zhuge Cai, which is not only beautiful, but also edible. As soon as the teacher's voice fell, we ran to the flowers and picked one and sent it to our mouths. Wow, it tastes a little sweet, great!
Then, we also know Liquidambar formosana, Reineckea latifolia and other plants that can treat rheumatism. I carefully recorded the knowledge I learned word by word, and painted it vividly with colored pens. Today's harvest is really a lot I think nature is really amazing, and I will continue to solve its mysteries one by one.
The Mysteries of Nature Composition 1 1 There are many mysteries in nature, and we must observe them carefully to discover their true meaning.
Flowers and plants are a big family in nature, among which exotic flowers and herbs are the most magical. Nepenthes are professional predators. It has a small pocket. It can secrete a kind of mucus that can stick things on it, and it can also give off a fresh fragrance to lure flying insects into the small pockets of pitcher plants. As soon as all kinds of bugs get into their pockets, they stick them in the pockets of pitcher plants and swallow small flying insects into their "courage" in one gulp. It breaks down small flying insects into nutrients and sucks them into its own body. You said it was magical or not!
Trees are indispensable and important members of nature. It's also amazing The crown can point the way. The leafy side is the south, and the leafy side is the north. Because there is plenty of sunshine in the south, there are many branches and leaves, and there is little sunshine in the north, so there are few branches and leaves. When you get lost in the wild or in the Woods, just look at the crown and you will know which side is south and which side is north! Tree rings can not only know the age of trees, but also record the climate! There are still many secrets in nature waiting for us to explore. As long as we have a pair of careful observation eyes, we can discover many mysteries of nature.
Careful observation and in-depth exploration are important links in learning and mastering scientific knowledge.
The Mystery of Nature Composition 12 Students, have you carefully observed the magic in nature? Today I will take you into the mysterious nature!
Do you know what scientists have invented from animals and plants? Let me tell you something! For example, scientists learned from bats that they can fly at night without hitting anything and invented radar. Based on the visual principle of frog eye, a successful scientific article-frog eye has been developed.
Today, I will take you to do an experiment!
We can prepare a cup of mimosa first. Why prepare? Because the last time I went to the park, I saw a kind of flower-mimosa, and now it will close when I touch it, so in order to solve the mystery of mimosa, I must prepare a mimosa. Then touch it gently, and then observe what happens to the water content of mimosa. If you really can't see it, you can prepare a book related to mimosa and check the information about mimosa. You will find that the petiole base of mimosa actually has an enlarged thin cell leaf pillow, which is filled with water. As soon as you touch it, its water will immediately roll to the upper and both sides, making the blade loose like a protective mold!
From this experiment, we can think that nature is very mysterious. As long as you pay attention, you will find many interesting things!
The Mystery of Nature Composition 13 There is an insignificant frog today, which aroused my curiosity.
Everyone has seen the frog, and he has become the research object of scientists for many years, which makes scientists discover that he has the ability to "turn a blind eye"; So he is not only a' king of killing insects', but also a hero who makes scientists recognize the' electronic frog eyes'!
It turns out that 100 years ago, scientists started their first experiment: put an electrical appliance in a room, pests flew around, and frogs quickly stuck out their tongues to catch pests. It has been proved many times that frog's eyes are Ming Rui.
The scientist did the second experiment, put the dead pest in, and the frog didn't move. This experiment proves that frogs "turn a blind eye" to still things. According to research findings, scientists invented' electronic frog eyes' from frogs, creating a new world.
More than 200 years later, with the help of electronic frog eyes, people can command planes to land more accurately. Nature is really a teacher of human beings!
The mystery of nature is endless, and we need to explore it with our heart!
The mystery of nature composition 14 The air after the rain is particularly fresh, and it seems that you can still smell the fragrance of the soil. Leaves are greener and flowers are redder. The weather is blue, and a flock of geese are flying in the sky.
I looked at the geese with ecstasy. The herringbone team is orderly, flying for a long time, but still not chaotic, like a well-trained soldier.
A question flashed through my mind: Why is the flying shape of geese herringbone instead of circle or square? Although I have seen geese fly like this, I have never explored the mystery.
I collected relevant information and read it carefully, and finally understood it.
It turns out that the goose in front is the most powerful and experienced young man in the group. Arranged in herringbone or herringbone, when the leading geese flap their powerful wings, they will drive the airflow, form a low-pressure area and reduce the air resistance. In this way, the old, weak and young geese can fly more easily and avoid falling behind. In the event of danger, the herringbone team can easily spread the geese everywhere, reducing the collision caused by panic. If the leading geese get tired of flying, other geese will take over the geese in front like relay races. The reason why geese can travel long distances is that they have a clear division of labor, know their role and unite as one.
If you are a conscientious person, you can master the mystery of any place. Maybe just when you look up and turn around, you will find that ...
The Mystery of Nature Composition 15 We live in nature. Actually, there are many mysteries in nature. For example, why can't raw eggs spin like cooked eggs? Why can't we breathe enough oxygen?
We live in exhausted oxygen, because there are flowers and trees that absorb carbon dioxide in the air and then use photosynthesis to produce oxygen, which is more and more fresh air.
Why not? Take the middle section of the willow branch and insert it in a sunny clearing on the roadside, and the willow branch will grow into a dense willow tree. Just a force of life. It is also because willow has a good personality that she can survive anywhere. Just like us humans, no matter where you are sent to work, you can do well.
Why can't fish live on land, but in water? That's because fish breathe with gills and we humans breathe with lungs, so fish can't leave anyone. Similarly, if we go into the water without oxygen, we will suffocate.
Nature is like a big textbook. As long as you study it carefully, you will have different gains and discoveries. Therefore, at the same time, we should do a good job in protecting nature, not polluting and destroying the environment, and not deforestation. If trees are cut down wantonly, there will be no fresh air on the earth.
We want everyone to understand that destroying nature is complete suicide! If you wantonly destroy nature, you will be punished by nature!
If you want to get mysteries and laws from nature, you must first know how to protect nature!
