I remember once, the science teacher asked us to observe snails. I was so excited that I didn't even take off my shoes. I went straight to "Little Snail", picked up a magnifying glass and began to observe. I looked at my head first and found two pairs of tentacles, one long and one short. According to the teacher, the snail's long tentacles can sense the changes of the surrounding environment, and its eyes are on the long tentacles, but it can only be seen clearly in the dark. Short tentacles are used to find food. I carefully put some leaves in. Sure enough, it was interesting to see the snail touch it with its short tentacles three times. I looked at my abdomen again and turned the snail upside down. I saw something glistening, but I didn't see anything. I checked the books on popular science, only to know that snails have abdominal feet in their abdomen, which can help snails crawl. I followed the snail's tail again. At this time, I saw that there was mucus where it climbed. I quickly asked my mother where the mucus came from. What is its function? Mom said that mucus comes from the tail, and snails can make it faster by following the mucus. Putting down the magnifying glass, I went to the elementary school encyclopedia to see if I had more knowledge about snails.
2. Observe how to write a snail's composition. It's raining in Mao Mao. After school, I found a big snail at the school gate. Its shell was very big and there were circles of patterns on its back, so I caught it and wanted to raise it.
When I got home, I kept the snail in a bottle and couldn't wait to observe it with a magnifying glass. I found that it has two pairs of tentacles, and there are two small eyes on the long pair, looking at me! I touched my antenna and it shrank back. Snails are very timid. They shrink their heads into their shells at the slightest movement.
I couldn't find its mouth, so I looked it up on the computer out of curiosity. It turns out that the snail's mouth is stuck to the ground. Only by turning it over can you see a small mouth. It also has teeth. It has the largest number of teeth in the world, with more than 25,000. I wanted to know how it eats food, so I brought a vegetable leaf and saw the snail "pounce" and ate it. After a while, the leaves were covered with large and small holes, and the snail lay on the leaves, as if very satisfied. I wanted to see how it crawled, so I took it out and put it on the ground. Snails crawl slowly, leaving a watermark behind them. These watermarks are snail excrement, which can help snails crawl!
I learned a lot by observing snails this time.
3. Observe how to write a diary snail's composition. There is a lovely little snail at home. I want to have a good look.
I found a brown "little house" on the snail's back. This "little house" is its shell. Its body will shrink into its shell when it is in danger, and it will take a long time to stick its head out carefully. Small snails also have two pairs of antennae, one long and the other short. A pair of short tentacles will touch the ground again and again when it crawls, just like two probe sticks, carefully checking whether there is anything on the ground. Those long tentacles with their small eyes at the top are looking at the world curiously.
I also found that snails move very slowly and climb very slowly. Moreover, when it crawls, its abdomen will secrete a mucus, so the place where the snail crawls will emit silver light. Snails are cowards, even eating is no exception. I have to put the leaves next to it, and it will eat them.
I also know that snails have the most teeth in the world. Small as it is, it has 22,000 teeth!
Watching snails taught me a lot. I will pay attention to everything around me in the future.
4. Write a composition of about 400 words on the topic "I discovered the secret of snails". Thank you. After the rain, several snails crawled on the flowers and plants in the garden. When I saw these snails, a big question mark suddenly popped up in my mind. Are snails beneficial or harmful? Why do snails leave sticky lines everywhere they climb? So I decided to study these two problems by myself. I caught some snails and put them on the ground. I also put some cabbage leaves and some small insects on the ground. They smelled cabbage leaves, poked their heads out of their shells and crawled towards them. After a while, they chewed a few Chinese cabbage leaves. It can be seen that pot cows are pests. Then I began to study why there was a sticky line where the snail climbed. I want to do this, I have to use a "cruel" method, so I crushed the snail's shell with one foot and the snail's meat was exposed. I tied a small stick and picked up the snail's meat. I saw many holes the size of suckers in the meat. There is mucus as disgusting as a snot. Now I can fully understand that snails persist through the sucker on their bodies until the evening. I discovered the secret of snails through my own experiments. I know the world is beautiful, Qian Qian. We should learn scientific knowledge well and learn more about the world.
I found the secret composition of snail, 400 words, and I found the unity of ants.
I like ants, not only because of their industrious and simple character, but also because of their spirit of helping each other in times of crisis and going forward bravely.
I remember once, several ants were crawling on the wall in a hurry. On impulse, I poured water from a teacup and threw it at the ants. They were frightened and fled everywhere. I poured water on them again, and they were all wrapped in water drops of different sizes.
Stubborn little ants are trapped in the water, but they still don't give up the chance to escape. They spread their legs thinner than needles and tried to climb to a dry place, but it was too late, and the water droplets as big as beans stuck to them like glue, making them unable to move. At this time, I saw them huddled together, holding hands, fighting bravely, and finally rushed out of the tight encirclement, exhausted, lying back to back together, encouraging each other. After a while, the long line lined up again.
Their team walked in the direction of the cake crumbs left by the rats. Then, the cake crumbs as big as broad beans disappeared. I moved the cake crumbs to another place, and the ants were not to be outdone. They found food at once. At this time, a group of ants came, and the cake crumbs disappeared from my eyes at once.
I looked at this group of ants and sighed. It is true that ants with big grains of rice are sometimes stronger than some people.
6. How to write a composition about snails? Snails have long eyes and a small mouth. There is a small house on its back under its head, probably because there is no place to hide when it rains. I quickly took it home.
Snail regards our flowerpot as grass. It likes to eat vegetable leaves. When I fed it leaves, it slowly approached the leaves and smelled them, huh? Snails have noses? Where is its nose? The science teacher told us that the two small tentacles next to its eyes are its nose! Look, the snail got the information about the food and began to suck the juice of the vegetable leaves with its small mouth.
Snails like to live in wet places. If you put it in a wet place, it will stick out quickly. If you put it in the sun, it will quickly retract its head into the shell.
Snails have a very strong crawling ability. One morning, I went to see the snail and found it was gone. I can't find it anywhere. At this moment, it suddenly occurred to me that when snails crawl, they will leave silvery traces. If I follow its crawling track, I will definitely find it. After searching and searching, it climbed onto the roof and stayed in its small house.
This is my lovely little snail.
Please adopt
7. Write a composition of about 400 words on the topic of "I discovered the secret of snails", thanking several snails for crawling on the flowers and plants in the garden after the rain.
When I saw these snails, a big question mark popped up in my mind. Are snails beneficial or harmful? Why do snails leave sticky lines everywhere they climb?
So, I decided to study these two problems by myself. I caught some snails and put them on the ground. I also put some cabbage leaves and some small insects on the ground.
They smelled the leaves of Chinese cabbage, poked their heads out of its shell and crawled towards them. In a short time, a few Chinese cabbage leaves were eaten up by them. It can be seen from this that pot cows are pests.
Then I began to study why the snail left a sticky line where it climbed. I want to do this, I have to use a "cruel" method, so I stepped on the snail's shell and the snail's meat was exposed.
I tied a small stick to pick up snail meat. I saw many sucker-sized holes in the meat, and in those holes, there was mucus as disgusting as snot.
Now I can fully understand that snails stick to the night through suckers. I discovered the secret of snails through my own experiments. I know this world is a wonderful Qian Qian. We should learn scientific knowledge well and learn more about the world.
8. The Lost Snail Composition The Lost Snail (original composition) Today, a small snail climbed into the white palette on the kitchen windowsill. I think it will nest here. I carefully took the color palette to my room and put it on the table.
It lies quietly in the middle of the plate. At first glance, I can't help thinking of a poem by Liu Yuxi: a green snail in a silver plate. The snail crawls around slowly with its small house on its back every day.
Its little spiral house is like a brown lollipop and a brown wool ball. Touch its little house, hard and rough, like a round pebble.
Snails are wet, cold, soft and sticky. Its eyes are a little different. They grow on tentacles, like butterflies' tentacles and like slender arms.
When crawling, its eyes kept swinging like two searchlights. Snails have a long neck and a long tail.
Wet and sticky liquid stays everywhere you climb, much like its urine. The house on the back swayed with the body, as if the wool ball was rolling.
When I gently touch its eyes with my hand, it will slowly retract its eyes into its tentacles, and then retract its tentacles into its head. After a while, it will be found that there is no danger, and then it will be extended. If you pick it up in a small house, it will shrink its whole body into the house.
However, this little snail seems to be very brave and curious, and soon reached out and continued to climb. If its shell is turned over, it will struggle desperately and try to turn it over and continue to climb.
It just kept crawling and crawling, as if in a hurry to do something. Are you in a hurry to go to school? It crawled along the palette one by one as if it were lost.
Oh, lonely snail, let me take you home! I took him to the wet grass in the park, hoping that he would never get lost again, have more partners and live a happier life! In the process of tutoring, my mother tutored the little snail lost in brackets (the topic is also a bit hard, originally it was "a little snail", but later it was written that it had been crawling. Did you get lost, so I thought about it and changed it to "A little snail got lost", and finally decided "A little snail got lost"). Today, a little snail climbed into the white palette on the kitchen windowsill. I think it's going to nest here. (Straight to the point, this is the structural pattern she is familiar with. No sooner had I asked how to cut to the chase than she got this sentence. I instructed her how to start, and she insisted on this sentence. That's all! ) I carefully took the palette to my room and put it on the table.
It lies quietly in the middle of the plate. At first glance, I can't help thinking of a poem by Liu Yuxi: a green snail in a silver plate. (The last sentence here was added in the second revision, and the whole article was completed. I asked her, did you think of any poems when you saw this scene? Because it was a poem she read not long ago, she immediately thought of it, but forgot who the poet was and looked it up in the book, hehe! Wang Dongting (Tang Dynasty) Liu Yuxi's lake and the autumn moon set each other off, and there was no windless mirror on the pool surface.
Look at the Dongting landscape. There is a green snail in the silver plate. The snail crawls around slowly with its small house on its back every day.
Its little spiral house is like a brown lollipop and a brown wool ball. Touch its little house, hard and rough, like a round pebble.
I thought of the house under my guidance. She used to walk around, but I suggested that she climb over. The second draft also added a spiral. What is the shell like? Gathering less and leaving more has inspired us for a long time. )
Snails are wet, cold, soft and sticky. Its eyes are a little different. They grow on tentacles, like butterflies' tentacles and like slender arms.
When crawling, its eyes kept swinging like two searchlights. Snails have a long neck and a long tail.
Wet and sticky liquid stays everywhere you climb, much like its urine. The house on the back swayed with the body, as if the wool ball was rolling.
This passage is written smoothly and may get better and better. Body symmetry is a good word. She said eyes grow on tentacles. I suddenly realized that I don't know where she knew it. She said that the application of the Italian method is like the tentacles of a bug. I suggest using butterfly tentacles. The last sentence, the movement of the house is related to the wool ball in front, which I think is excellent.
Of course, before she left for our home, we called a thousand times and urged her a thousand times. When I gently touch its eyes with my hand, it will slowly retract its eyes into its tentacles, and then retract its tentacles into its head. After a while, it will find that there is no danger, and then it will stick out again.
If you pick it up in a small house, it will shrink its whole body into the house. However, this little snail seems to be very brave and curious, and soon reached out and continued to climb.
If its shell is turned over, it will struggle desperately and try to turn it over and continue to climb. (We recorded it while observing and chatting. Remember to read it, polish it and modify it.
The little snail is really proud and cooperative, but keeps climbing. The child's light flashes again and again, and sometimes I encourage her when she feels inappropriate. What else can I say? Which do you think is better? Finally, the snail was tired, and we almost finished writing. While resting in the palette, it happened that Liu Yuxi's poems were caught by the children. ) It just keeps crawling, as if in a hurry to do something.
Are you in a hurry to go to school? It crawled along the palette one by one as if it were lost. Oh, lonely snail, let me take you home! (Because it has been crawling, the child asked if it was in a hurry to go to school, and later mentioned that it couldn't find its home-it was lost.
So the child's love came and wanted to send it back. I asked the snail how you felt about getting lost, and she said she was very sad, worried and distressed.
Then I used a lonely snail-I think it is a poor snail, but I respect the child's idea. I took it to the wet grass in the park, hoping that it would never get lost again, and that it would have more partners and a happier life! The last blessing is indispensable. Her feet are entirely her own idea. I'm just responsible for squeezing toothpaste constantly, and then let her organize the language and make it smooth. )
9. How to write 400 words for the composition of snail adventure? Speaking of snails, everyone must be familiar! I caught two snails in a small jar on the balcony. I go to see them every day as long as I have time. The snail's body is very soft, and there are four "tentacles" on its head-the last two are its nose; The two long ones are snail eyes. Snails carry a hard shell like conch on their backs. This is the "small house" where it lives. If it is tired or in danger, it will shrink into this "small house".
Once, it suddenly occurred to me why not let two snails race? Do it. I put two snails on the card and marked it carefully.
The game is about to start. I invited two players to play and let them do "warm-up exercises". At the beginning of the game, as a referee, I was anxious like an ant on hot bricks, while these two players were crawling slowly. It took two snails about four minutes to climb five inches. How slow! I have to wait patiently. Finally, the first runner crossed the finish line and won.
I observed it carefully and found that there were two shiny lines where they ran. Interestingly, athletes even draw "runways" for themselves!
In order to treat them, I put a small piece of cucumber and a small piece of tomato in their room. I watched them with interest. I saw that snail 1 only picked cucumbers to eat, and snail # 2 only picked tomatoes to eat. I watched them eat with relish and laugh happily.
After dinner, when I visited them again, I found red and green feces in the "living room". In order to find out, I fed snail 1 a little orange and snail 2 a little melon, so I'll wait and see.
The next morning, when I visited them, I found some yellow and white feces in the "living room". From this, I understand that the color of snail feces is related to the pigment in food.
These two little snails are really interesting! They bring me happiness, knowledge and a studious heart.
