? I like the countryside, and I want to take my children to feel the wonderful beauty of the four seasons wherever I go. In contact with nature, in addition to absorbing the aura of heaven and earth, feel the wonderful beauty of the four seasons! It can exercise children's keen observation and various learning abilities and interests, and even I know a different perspective! The scenery that was originally plain and used to thinking empty was endowed with strange beauty.
? Last year, I met a primary school friend who loves nature. Xiaoguo's classmates also like all kinds of insects. I also witnessed the growth of children all the way, from being a little afraid of insects at the beginning to understanding their habits and seeing their growth and transformation, not strangers. The process from fear to not being afraid, and then to showing and explaining to people in an orderly and logical way is not the process of children's own growth. But the sequelae of these things, you need a magnifying glass when you go out. ) haha

It's cicada catching season again. The plot of chilling and shelling observed last year is still vivid. However, the last time was shelled in the early hours of the morning. If the students didn't wait for the shelling, they fell asleep. I also want to see this wonderful change, so the cicada catching team was established again.
At noon, the leader of Xiaoguo listened attentively first, found the tree with the loudest cicada, saw many holes with thick fingers, all left by cicadas, and looked up at the leaves with many cicada shells!
Stroll through the forest and write an ancient poem. The shepherd boy rode a yellow ox, singing loudly, trying to catch cicadas, and suddenly stood there silently. It really fits.
Speaking of ancient poems about singing cicadas, the poems of three poets, Luo, Yu Shinan and Li Shangyin, are called "three unique poems about singing cicadas". If we hadn't prepared our lessons in advance, my mother wouldn't have said so much about cicadas. Reading poetry with Allegro is very poetic, isn't it?
? Cicada droops like a tassel on a hat, its tentacles suck the clear dew, and its voice spreads from the branches of the straight Shulang tree.
Cicada is far away from cicada because cicada is on a tall tree, not relying on autumn wind.
? If it is not enough to tell these ancient poetry stories, there are many idiom stories: silence, mantis catching cicada, yellowbird behind, story of losing Xin full, cicada unlined upper garment forest belt, thin cicada wings, really no cicada! Tell me what you want to know.
? With the accumulation of natural observation last year, this year we skillfully discovered the holes that the little guys have not yet unearthed. Looking for those small holes the size of mung beans, I couldn't find them after digging several holes. Is it the wrong time? Evening is a good time for cicadas to come out of their holes, but fortunately, they dug half a foot in the Woods and finally caught two crawling cicadas, but one of them was unfortunately injured by his mother, leaving only a precious crawling cicada.
These underground cicadas are called nymphs. They suck juice from the roots of plants to sustain life. We dug a small hole and found its underground palace. There are many roots beside the big tree for them to eat. Imagine what a comfortable palace this is! How do cicadas dig holes? Why is its tunnel clean and smooth?

? The evolution of natural species also makes cicadas learn to choose the right time to go out, so they only go out after dusk, usually from 8 pm to 6 am. If they are unearthed during the day, they can easily become a good meal for other creatures. So the thrilling journey at night is not so dangerous. But unexpectedly, this noon is also the cicada's nightmare. It was caught by a kind little boy. What will be waiting for it? Let's have an illustrated cicada adventure!
? I heard that cicadas should have lived underground for 4 to 5 years. The shortest is living underground for 2 to 3 years, and the longest is 17 years. They must undergo five or six underground metamorphosis before they can grow into adults. They break out of the ground at the end of June every year and climb trees. Every time the larva metamorphoses, it will leave a cicada shell, which will be more impressive than its own observation.
It is incredible how it accurately determines the time, whether it is 3 years, 5 years or 17 years, all these years have one thing in common, they are all prime numbers. This is because there are few prime factors, which can prevent them from drilling out with other cicadas when they drill out of the soil, competing for territory and food. Entomologists also think this is a miracle. Entomologists always wait for cicadas to appear in 17, just as astronomers wait for solar eclipses and halley's comet. Xiaoguo classmates also want to know! Let's consult the book network for a dialogue! Looking forward to our guide map?
No matter how many years you live underground, cicadas can only survive for one summer. Reminds us of Insects: cicadas lurk underground for four years before they can get out of the ground and sing in the sun for five weeks, which reminds people of the philosophy of life! Whether life is short or not, we should face it positively and live a good life. It turns out that philosophy is everywhere in life!
In ancient times, China people thought it was an endless and endless creature. The jade cicada placed in the mouth of the deceased in the tomb also symbolizes resurrection and eternal life. The image of cicada appeared on bronze wares in Shang Dynasty. From the late Zhou Dynasty to the funeral of Han Dynasty, it was a custom for the dead to hold cicadas in their mouths.
? The ancients also thought that cicadas were virtuous animals, so the crowns worn by attendants in the Han Dynasty were decorated with cicadas and inserted with mink tails, so they were also called the story of losing Xin Guan.
? I wonder if these can be found in the museum. Write down this little task first!
? four
? We took this precious little guy home and watched it change. As soon as we got home, we put the cicada on the screen window to simulate the tree it climbed. Fortunately, it began to go bad at dinner. First, a black crack appeared on the back of cicada pupa, and molting officially began. The head comes out first, then the straw and front legs, then the hind legs and still folded wings. When the whole body came out, it adjusted its state, turned its body upside down, chopped it on the shell with hooked legs, and finally took off its tail and came out! It's like climbing out of a pair of armor, and the whole process takes about an hour. It turns out that this is the "golden cicada shelling".
? The wings of the newly hatched cicada are still very soft. After eclosion for some time, it tried to climb to the top of the window and flew. Like a runaway helicopter, it swooped down on me and Xiaoguo's classmates. As soon as we dodged, it hit the curtain. The first test flight failed. It stayed there quietly and did not move. Why doesn't it sing? We went to check the information again and speculated that it was a female cicada, a dumb girl who couldn't sing, and the male cicada was a "big singer". The male cicada has a special vocal organ in the abdomen, which vibrates the eardrum to make a loud sound.

? Natural observation of the philosophy of life in Insect and appreciation of mind maps of ancient poems can also guide children in this way. Isn't this the so-called general education?
? Reminiscent of the topic of junior high school in Zhengzhou, a test paper takes students into the "Henan Museum". Students need to comprehensively use the knowledge of Chinese, mathematics, foreign languages, science, art, etc. in primary schools, and conduct situational and inquiry-based learning in various venues of museums. This is exactly the goal of our efforts. Usually, general counseling, general enlightenment of Chinese, mathematics, English thinking and historical space expression art movement will not be the ability that a single subject remedial class can improve!
? To borrow a sentence from Mr. Walter WANG and Mr. Ding Baoxian: "As far as taking the exam is concerned, a child with extensive reading experience does not care whether he has read the books involved in the examination paper, but has enough ability because of extensive reading. He can understand any text, even if he moves to any topic, he can find clues to solve this problem. Once such accomplishment and self-confidence are formed, they will move towards a broad future in the future. What are their fears when they encounter problems that are not "learned" in books, classes and remedial classes? "
"Reading ability, thinking ability, scientific inquiry ability and comprehensive practical ability ... this is the correct posture to open the world. Please cherish the comprehensive practical activities and face the unknown world with the attitude of research learning. "
That's right. This road can be "routine" by parents.

The fun of nature practice, do you want to make an appointment? Come with us on the next nature trip!
"When children grow up, they should feel the nature around them carefully. In my opinion, this is a very important thing. The world of animals, plants, fungi and other creatures is full of incredible things. As long as you observe carefully with curiosity, you will find things that you couldn't see before, thus discovering the new continent. From nature, you can find the true meaning of' living'. " Children should grow up with rich nature and warm human feelings. The beauty and mystery of nature can also take root in a child's mind and become a source in their hearts to fight against possible burnout and disillusionment in the years to come!
