Take a closer look at the things around us and you'll notice how wonderful nature is around us, and every wonderful moment will last a lifetime. In my careful observation, I have made many discoveries, but many of them have been forgotten with the passage of time, and there is only one discovery that I still remember.

It was a rainy spring day, the sky was full of lead clouds, it was very hot, and it looked like it was about to rain. I'm a very curious child, and this time I had a new idea: what do the animals do before it rains?

So, I went out into the wild to observe the animals' "behavior" before the rain. The first thing that caught my eye was a long line from the top of the wall to the corner, that is, the ant "army". I leaned down and found that they were carrying food heavier than they had and some nesting stuff.

Will these things be shipped to **? So I followed this long line to find the source, and sure enough, it was an ant's nest. Why do ants desperately move when it rains?

I searched for answers with questions. It turned out that the petite bodies of ants could not withstand the test of wind and rain, so they planned a clever plan, that is, to move, to move their home from a low-lying place to a high place - the most comfortable and safest place to place it in their own home. "Hehe, can't we hide if we can't afford to provoke?

So, they gather food before the rain and wait for a storm to subside. Not only ants, but dogs can also have a strange behavior before it rains. I don't know if you've noticed, but the dogs stick out their tongues and make gasping sounds in the summer, because they rely on their tongues to dissipate heat.

If it's too hot to stand before it rains, they call out to their brother and brother to take a dip in cold water by the river to relieve the heat: "Dude, go!" Let's take a cold shower by the river, refreshing!

Therefore, under normal circumstances, the dogs will go to the river to wash before the rain. There is another person who can be a weather forecaster for people before the rain, and that is a snake who has practiced a beautiful dance. Speaking of snakes, many people are famous for their sharp teeth and cold nature.

Indeed, there are no quick limbs but can move freely, no enlarged body can dominate one side, and low hearing and vision can be responsive. Snakes generally move at night, and in the dead of night, the land becomes their paradise, but before the rain, due to the stuffy heat in the cave, many snakes will come out to breathe and move. I think this is the origin of the folk proverb that "ants move and snake aisles, and there will be heavy rain tomorrow".

I learned a lot from this survey! Animals and nature are inextricably linked, and we live in a big family, so we should care for each other and live in harmony. Students, listen to my findings.

I discovered the unpretentious beauty in life.

There is no lack of beauty in life, but a lack of eyes to find it. "With a pair of eyes that are no longer critical and a quiet heart, I have discovered the beauty in my heart.

In nature, spring is full of flowers, plants and trees are beautiful. Although the grass is not as beautiful as the peony and the rhododendron, it is strong, and it experiences wind and rain, lightning and thunder. Some of the water is magnificent, and some are as horizontal as a mirror.

Some of the mountains are too steep, some are too respectful, and some are too expensive. How beautiful is it, I don't tremble, what trembles me? It is the beauty of nature.

You see, under the windowsill of the teacher's office. The teacher is still working hard to correct the homework, and your family and relatives are still waiting for you to go back to dinner! Bottle after bottle of used ink, bottle after bottle of broken red pen.

I don't know how much ink you've used up and how many pens you've broken over the years. Teacher, you've done a great job! You've had another hard day, so don't bother with us!

Ah, what a teacher, what a touching scene!

In response to the afterglow of the sunset, there is a little yellow light on the path. I was walking on the path home, when an old lady with pale hair accidentally fell, a little classmate immediately stepped forward to help, helped the old man to the distance, watching the figure of the old and the young gradually disappear, my heart instantly became warm, what a beautiful moment, what a beautiful moment. The lights in the corridor are still on, I know, this must be the child of which family has not come back, parents are afraid that he is afraid, light the lamp and wait for the child to come home.

What a wonderful time, O Father, Mother, how much love you have given me since I came into this world? How much more will I be given? Ah, my father, my mother, I love you!

What is beauty in life, this is the beauty in life, it is such a simple, ordinary little thing.

Everyone may discover some mystery of something, and there will be many experiences in the process of discovery, of course, even I, a person who does not like to discover, will discover the mystery of things, if you don't believe it, please listen carefully.

It was ...... on a hot and cool summer day

My sister and I were playing by the pond. Suddenly, a small red fish jumped out, a graceful dolphin-style diving action, with water droplets like a naughty child landed on the lotus leaf, rolled, turned over, and jumped up again, a flawless diving action was born.

I think that the lotus leaf must have been wet with water droplets, and the lotus leaf has no towel, so it is easy to catch a cold, and it can't take medicine. I dried it to give it a chance to sunbathe. So, I dragged the lotus leaves out of the pond with my own mopping floors.

Touch the lotus leaf with your hand, well, fluffy, and the texture is not bad. Take a closer look, huh? How did you do it?

I didn't believe it, so I put the lotus leaves in the pond and soaked for a while, and when I picked it up, it was still dry. Is it that the lotus leaf is too hot, and when it is hot, it will be thirsty; When you're thirsty, you want to drink water, so you swallow it, right? It must be like this.

I would like to see how lotus leaves can drink water without a mouth. So, I didn't care if the lotus leaf felt cold or not, and let it soak for a while. This time, I watched with excitement with wide eyes, and my heart was still beating "thump" from time to time, for fear of missing the scene where the water droplets were eaten by lotus leaves.

However, it backfired, and the water droplets were not eaten by the lotus leaves, but "bounced" into the water like marbles.

Why don't lotus leaves get wet? "I walked into the study with questions and opened '100,000 Whys'. A check, oh, it turned out that there was a nano film composed of nanometers on the surface of the lotus leaf.

The nano film is spread on the surface of the lotus leaf, making the lotus leaf smooth, as if putting on a waterproof coat for the lotus leaf.

- my findings.

There are many flowers on the balcony of my house, including rhododendrons, lilies, and spring. But I don't like it, I just have a love for the little mimosa.

The stem of the mimosa is slender, the leaves are turquoise, and it is composed of dozens of leaves, with a 'tendon' in the middle, which strings together the small leaves, and the mimosa is like a shy little girl. As soon as you touch it, the whole leaf immediately closes and the branches hang down, which is really interesting! My brother and I especially like to tease it, and whenever we have time, we run over and "shame it."

On Sunday morning, my cousin came to my house to play with the mimosa. Suddenly, I noticed that the mimosa leaves were closing much slower than they had been a while ago. I kept fiddling with it, and finally it didn't move!

I screamed and kept playing with the mimosa, but the mimosa just didn't move, what's the matter? Has his skin thickened? Or is it being annoyed by us?

I couldn't figure it out.

After lunch, I eagerly looked up information on the Internet and finally understood the mystery.

It turns out that the place where the small petioles, large petioles and compound petioles of mimosas are connected to the stem axis is called leaf pillows, and there is water in the leaf pillows. When we touch the leaf, the water in the upper cells of the leaf pillow will flow to the gaps of other cells, and the upper part of the leaf pillow will be folded, so the mimosa will appear "shy". However, when we often touch it continuously, the cell fluid in its leaf pillow is drained, and when the new cell fluid is not replenished, there is a "shameless" situation.

I discovered microbes, writing microscopes in science class.

"I Discovered the Secret of Eggs".

It's almost the New Year, one day, grandma was cooking bacon, and by the way, she put a few hard-boiled eggs in to cook together. I saw a few hard-boiled eggs on the table, so I took one and put it on the table to play. I saw that there were still a few eggs on the other end of the table, so I took another one and played with it.

I held an egg in my left hand and an egg in my right hand, and I spun it around on the table. In the beginning, the egg in the left hand did not make as many turns as the egg in the right hand. I thought it was because the strength of my left hand was not as strong as that of my right hand, so I swapped the eggs in both hands, and it turned out that the eggs in my left hand made more turns than the eggs in my right hand.

I wondered: what's going on? Suddenly it occurred to me that :

Raw eggs can't be turned. Could it be that one of these two eggs is a raw egg? I put the two eggs to my ear and shook them, one of them was silent and the other sounded like water was shaking off the side.

As I expected, one of the two eggs was a boiled egg and the other was a raw egg. I held two eggs and thought: why do hard-boiled eggs make more turns than raw eggs?

With this question in mind, I started looking into this question. I placed the two eggs on the table and spun them vigorously and observed the difference between the two eggs. Suddenly, I realized that the raw egg could only turn a few times when it turned up, and it quickly collapsed.

And the hard-boiled eggs kept turning. The hard-boiled egg spun around and almost landed on the ground, but thankfully I was able to hold it back before it hit the ground. Suddenly my inspiration struck:

Is it because one of the eggs is liquid and the other is solid? Since it is solid, why do it make so many turns? I picked up the hard-boiled egg and spun it around, and suddenly it thought:

Is it because the egg white and yolk inside the cooked egg are already cooked, and the shape is exactly the same as the outer shell? I held the egg and thought about it for a long time, thinking about it, and I suddenly thought: after the egg is cooked, the egg shell is connected with a layer of egg skin and egg white.

Thinking of this, I suddenly understood: the egg white inside the boiled egg is solid, and when it turns, the egg white will rotate with the eggshell. The egg white inside the raw egg is liquid, once the speed of the eggshell slows down, but when it starts to tilt, the egg white inside will spread out like water and fall down with the eggshell, so the cooked egg turns more times.

Yes! Why do hard-boiled eggs make more turns than raw eggs, this question has finally been solved by me after my efforts, and I am so happy in my heart!

100% I wrote it myself.

Have you ever wondered? There is science in those seemingly ordinary things? Have you ever wondered? There's also science in the ordinary tea. It was by chance that I discovered the science in tea.

One day, while peeling an apple, I accidentally cut my finger, and blood gushed out. Stunned, seeing a cup of tea on the coffee table, he stuck his finger into it. Unexpectedly, the bleeding stopped after a while, and the wound didn't seem to be so painful.

I thought it was a psychological effect, and I didn't take it seriously.

Then one time, I fell on the balcony. The skin of the palm of the hand was scratched in one piece. With the mentality of giving it a try, he once again soaked his palm in the tea.

Strangely, the bleeding stopped again! Told his classmates about it, and they also began to treat the small bleeding wounds with tea. They also tell that the stronger the tea, the better.

The students were very curious about this effect of tea, so they asked the teacher. Teacher Guidance We looked up the materials. It turns out that tea contains a large amount of ampophylline, which can temporarily anesthetize nerve endings, so that the local pain nerves in the human body appear dormant for a short time and do not feel pain.

Alkali can also sterilize, prevent wound infection, dissolve surface or subcutaneous sediment, make full contact between wound broken muscles, ensure muscle growth, and speed up wound healing. If the temperature of the tea is low, it will also make the capillaries of the wound tense and constrict, which will have the effect of sealing the wound, and the bleeding will stop.

As long as you observe carefully, you will find that there is science everywhere in life!
