I discovered the mystery of nature.

Nature is a wonderful world with many amazing mysteries. This humble frog aroused my curiosity.

Everyone has seen the frog, and he has become the research object of scientists for many years, which has made 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.

Scientists set up a second experiment, putting dead pests 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! Ask close questions

Youth newspaper to write about the mysteries of nature?

How beautiful the blue sky and white clouds are! ?

I found (a composition about the mystery of plants in nature). There are many mysteries in nature. There are many strange things in the plant world, and there are many novel things. Let me explore and discover! Why can cactus survive in the desert? Because they have a special place to store water in their bodies, they evolved their leaves into their own thorns, so that their water could not evaporate in large quantities.

In other words, if they become thorns, they can prevent sunlight from absorbing the water of cactus and live in the desert for a long time, so they are the most beautiful scenery in the desert.

Why are mimosa shy? Some people say that because it is called mimosa, it must be shy! No, because there is something called a leaf pillow in the leaves of mimosa. There is some water in the pillow. If you break the leaf pillow by hand, it will flow out. When the mimosa feels it, it will contract its body. When it shrinks, it looks like a shy girl.

Why can Nepenthes eat those little insects? Because Nepenthes looks like a bottle with a small lid on it, there is a fragrant honey on its wall. Some small insects smell the fragrance and fly in the direction of the fragrance. It seems that they are curious and want to fly to eat honey. Because Nepenthes is smooth, those bugs accidentally slip in, and there are some digestive juices in it, which can digest small bugs. The little insect flew, but was caught by Nepenthes. The mysteries of nature let us know a lot of knowledge, and also let me know how novel and energetic the plant kingdom is.

They use their own methods to protect themselves and also use their own methods to maintain their own lives.

Just like us, they know how to cherish their lives and not be bullied by others. How beautiful the plant kingdom is! ! ! ...

I discovered the mystery of nature. The whole nature is a wonderful world with many amazing mysteries and unremarkable frogs, which aroused my curiosity.

I love nature. You know the mysteries of nature. I love nature. Colorful nature is wonderful, harmonious, magnificent and lovely! I love nature, I love its beautiful scenery, beautiful emotions and beautiful language in spring, summer, autumn and winter ... Spring breeze touches nature, it comes to the earth, puts green clothes on the earth, brings back swallows and wakes up frogs.

Everything opened its eyes and looked around. Many trees, such as willow, poplar, apricot and apple, have grown small green leaves.

Birds are singing and the wind is blowing gently.

Everything on earth has started a new day.

The season of the year is in spring. How beautiful spring is! Spring has gone, and summer has come again. The grass grows tall and the trees flourish. Only flowers are sad. The tree asked what happened to it. It said, "I'm going to be cooked by the hot sun."

"After hearing what it said, the tree felt his sweat streaming down. The tree thought, "It's really hot! If only it could rain.

I was thinking there would be a thunderstorm when it came.

The rain fell heavily on the tree's head, and the tree cheered and everyone laughed.

Summer is hot and fierce.

In a blink of an eye, the earth has been covered with yellow clothes-autumn has arrived.

The leaves were all dyed yellow by nature's hairdresser.

Autumn is a beautiful season.

Look forward to it. Winter is coming and the weather is getting cold.

The earth is covered with thick white clothes, the biting cold wind blows, and the snow hits the tree head, which is very comfortable. This reminds the tree of the proverb "Snow indicates a bumper harvest year", which indicates that next year will be more prosperous ... This is an essential change.

How beautiful! I love you.-Nature.

The four seasons in nature are beautiful.

Spring sprouts, summer flourishes, autumn harvests and winter recuperation. Our world is rich and colorful due to the four seasons.

Chun is a painter.

"Xiao see red wet place, spend a lot of money in Guancheng.

When I recite this poem, the beauty of spring seems to be on a piece of paper, and a brush is sketching the outline of spring: peach trees are blooming brightly, farmers are planting new rice, grass is drilling underground, and willows are spitting out new branches.

Spring is the beginning of a year. "A year's plan lies in spring" is full of vitality everywhere, sowing the seeds of hope in the ground.

Xia is an artist.

"Daohuaxiang said a bumper harvest, listening to frogs.

"The fiery red sun hung high in the sky, so hot and dazzling that everyone dared not go out, but the cicada was busy and singing loudly.

In the evening, people who stay at home all day come out to enjoy the cool.

People came to the square, singing and dancing.

In the countryside, in the mountains, in any corner of nature, animals are unwilling to lag behind. They got together and held a forest symphony, in which frogs and cicadas became the protagonists.

Qiu is a natural scientist.

"Sow a millet in spring and harvest 10,000 seeds in autumn.

Autumn is the harvest season, farmers are harvesting rice, and the fields are busy.

The autumn wind is rustling, the rice fields are bumper, the leaves are red as fire, the sky is blue as the sea, and the beauty of autumn is everywhere, without the contribution of this natural scientist.

Dong is a photographer.

"The window contains autumn snow in Xiling, and Wu Dong Wan Li berths at the door.

"Snow, the earth seems to be covered with a white coat. She quietly photographed the whiteness and vastness of winter, and she left an eternal and beautiful memory of winter with her lens.

The four seasons of nature are fascinating, they come from nature, and nature is colorful under the influence of the four seasons.

Nature is even more magical, and there are many beautiful scenery and phenomena waiting for us to discover and explore.

The mystery of nature Grandma homework help gently picked them up, dusted them off and mysteriously said to me, "Let's go home and plant them!" "What, use a shovel to compact the soil around the leaves, and we'll see if these two leaves are alive.

But every time the leaves don't move, which makes me disappointed.

"So I sat tight. A week later, the leaves grew. I put them in the yard and studied them carefully. I also sprinkled some water.

I'm so happy. My grandmother asked me to put it in a small bag.

I asked curiously, "grandma, what shall we do with them?" Bookmarks? Make a specimen? " "No,no..

"Grandma smiled and shook her head.

Then bend down and everything grows.

"Grandma and I sold the imprison son.

Go home.

"It tells me the secret of nature, and it also tells me that as long as you pay attention to observation.

They are generally very energetic.

It is not so much a leaf as a finely crafted work of art.

Grandma and I listen to stories in beautiful spring.

On the dark green leaves, a touch of white spread regularly, and many green spots appeared below.

Later, every few days, life was full of mystery. Leaves can be planted, and the world is beautiful.

People who love to observe and think find two extremely beautiful leaves on the roadside? "I'm surprised!" You'll know when you get home.

It won't be long before we take care of them more carefully.

I told my grandmother what I had observed, and I made new discoveries every moment.

So I found the secret of nature in this seemingly dull life.

Spring.

In my expectation, many thin white beards grew under the leaves, and the flowerpot was covered with soil.

Then she took out two leaves and planted them carefully in a flowerpot: "As long as the leaves are not rotten, they are not dead. The grass grows and the warbler flies. Grandma found a beautiful flowerpot and beat the soil in the flowerpot very fine with a shovel.

In the eyes of casual people who love life.

Up to now, they have grown into two bonsai plants.

Grandma told me: "In nature, many plants grow by cutting." ...

I learned the life characteristics and special abilities of woodpeckers and anteaters from the revelation of nature. From them, I suddenly thought of a problem and got an inspiration: in rural orchards, we often find pests drilling into tree trunks and mature fruits. In order to protect the fruit trees, farmers have to spray a lot of pesticides. What is the result? Not only is the cost high, but people eat it, and the pesticides that exceed the standard are scary. If pests are not killed in time, people have to cut down those "incurable" fruit trees.

In modern rural areas, it is impossible for so many woodpeckers to help fruit trees see a doctor.

Nature has given people a lot of inspiration. Planes were invented according to dragonflies, and streamlined boats were invented after whales at the bottom of the sea. So I'm thinking: why don't we make a portable pest control machine by imitating the mouth of woodpecker and the tongue of anteater? In this pest control machine, we can install a computer chip, so that it can accurately detect diseased trees. Then, we can press a red button on the handle, and a pointed hooked steel pipe similar to a woodpecker's mouth will pop out from it. It can accurately make a tiny hole in a tree with pests, and then hook it out with a hooked steel pipe mouth.

What about termites? Don't panic, we can put the steel pipe mouth in first, then press the green button, and an anteater-like tongue will pop out of it. As soon as the sticky long tongue "drills" into the hole, termites are easily and completely eliminated.

How beautiful nature is! I love nature!

A short article about "the mystery of nature", about 200 words. Nature is subtle, strange and magical. In the wonderful nature, you can feel the enlightenment of life, cause careful thinking and produce unique associations ... For example, a drop of water can wear a stone-a small drop of water. Its persistent efforts defeated the hard stone, defeated the ocean that could be stronger than him but arrogant, and defeated itself. Besides, nature can teach us some physics knowledge. It is reported that a forest after a heavy rain caused a fire. Relevant departments are investigating the reasons ... small water droplets may cause fire under the irradiation of sunlight, because they can be used as convex lenses to condense light, so they will cause fire; That unique association, in ancient times, people wanted to go to the distant moon and see Chang 'e and Jade Rabbit there. This is a beautiful imagination and a touching legend. Isn't this the association between Chang 'e and Yutu on the moon? This may be made up by people going to the moon, so that everyone can work hard for this goal ... This nature really makes people learn a lot of knowledge, so nature, like our teacher, lets us discover beauty from life and practice and discover knowledge that is not in textbooks. Nature is our good friend, our mentor and friend, a beautiful song and a lyric ancient poem. This is a touching and beautiful legend. We all have the experience of being close to nature, knowing nature and feeling nature. Facing the sunrise and sunset every day, the flowers bloom and fall every year, the towering peaks and the deep sea for tens of thousands of years. ...

I didn't expect the mystery of nature. A few days ago, we learned a text called "Mother plant has a way", which said: "... mother cocklebur has a good way. She dressed her children in barbed armor. As long as she hangs animal fur, the children can go to the fields and valleys ... ".

The literature class is over, but we grew up in the city, and neither my sister nor I know Xanthium sibiricum. We really want to know.

As it happens, today we are going to grandpa's house in the countryside, and my parents decided to take this opportunity to take us to know Xanthium sibiricum on the spot.

There are so many plants in the field. After searching for a long time, we saw green Parthenocissus tricuspidata, furry Mao Mao dog, and bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter bitter.

On the way, my father suddenly asked us to come and see an old cow. It turns out that there are many xanthium hanging on the old cow, and the old cow really takes them everywhere.

We can only look at Xanthium sibiricum from a distance for fear that scalpers will kick us.

When I was approaching Xiao Ye's door, my mother suddenly cried out in surprise: "Far away, just in front of me, come and see, there is a Xanthium sibiricum!" We rushed over and squatted down to observe carefully, only to find that there were really many hard little thorns on the oval body of Xanthium sibiricum. It's like wearing a barbed armor. I think it's like a weapon used in ancient wars.

Haha, we know Xanthium sibiricum! Today we know Xanthium sibiricum, tomorrow we will know more things and use our knowledge to solve the mysteries of nature.

There are many secrets in nature, which can only be discovered after many experiments and practices.

In this way, I discovered the secret of apple discoloration.

On this day, I came home and found a guest in our house.

I peeled an apple for my guest.

Who knows, the guest forgot to eat.

When I sent the guests away, I was surprised to find that the apple had turned yellow.

Why do apples turn brown? The problem snowballed in my mind.

I decided to ask my father. I asked him inexplicably, "Dad, Dad, why do apples turn brown?" My father looked away from the computer screen and said kindly to me, "Little darling, let's do an experiment!" " "Dad took a big round apple and cut it into three pieces. The first piece is in a bowl, the second piece is in a bowl with a glass cover, and the third piece is in salt water.

What are you doing at this time? Dad seemed to see through my mind and said mysteriously, "You will know later."

After a while, I can't wait to have a look. The first apple is brown, the second apple is a little light brown, and the third apple is the same as before.

I took a bite, wow! What a beautiful day! It's really cool Before my father could speak, I said to my father, "Dad, why?" Dad gave a dry cough and said, "Because there is a substance called enzyme in the apple, it will become oxidase when it meets oxygen, which will make the apple discolor."

"I went on to say," and covering the lid will reduce the connection between the apple and oxygen, thus making the apple slightly discolored.

Right, dad? ""that's right.

""But why doesn't it change color in salt water? " "Because salt water completely prevents apples from being dissolved by oxygen, and salt will stimulate the sweetness of apples and make them sweet.

So salt and various fruits are husband and wife.

"Dad replied humorously," So that's it! " I nodded involuntarily.

It seems that the first half of the sentence "there is learning everywhere, and three people must learn from each other's strengths" is really right! It seems that I will observe things around me more attentively in the future.

I have raised morning glory, aloe and chlorophytum in my family, among which aloe is my favorite. The stem of aloe vera is thick and strong. The blade bends downward, and there are many triangular serrations on the edge of the blade. All the leaves grow alternately, and none of them overlap. There is a film on the leaves. When you open it, you can see that the meat inside is very thick and juicy, and it is slippery and sticks to your face. It opened. Even if there is not a drop of water in the soil, it can survive because its leaves are full of water. I like aloe vera because it can diminish inflammation, and it can treat tracheitis and pharyngitis. If someone gets these diseases or injuries, they can be treated with aloe. I water it once every two weeks and go home every day to see if the aloe vera is dry. When I saw Aloe smiling, I said to it, "Little Aloe, you are thirsty." Little Aloe seemed to hear my words and replied, "Little master, go and do your homework. I am not thirsty. " If you are tired of doing homework, you can go to see the flowers and loosen them, so you won't feel so tired. When it is sick, I will water it more and tell it, "Don't be afraid, be strong, and you will be fine." It seems to say, "little aloe vera. It seems to say to me, "Don't be afraid, young master, if you have confidence in yourself like me, you will be fine.". "The indomitable spirit of Aloe inspires me. I will think of the spirit of Aloe when I encounter difficulties in my future life and study, so that I can overcome difficulties tenaciously and face life bravely.
