Observe snail diary
The days are about to pass, and I believe everyone must have a deep feeling. Let's sit down and keep a diary. But how can I keep a diary to shine? The following is my snail observation diary for your reference only. Welcome to reading.
Watch snail diary 1 Have you ever watched snails? Have you ever raised snails? There is a small snail at home. I will observe it as soon as I have time.
Snails have their own houses, which we call shells. Wherever it goes, it always carries a heavy shell. No wonder it walks so slowly. It has two pairs of antennae on its head, one long and one short, and a pair of eyes at the top of the long antennae. If something touches its eyes, the snail's tentacles will retract quickly, very sensitive, not as slow as usual. Snails have no feet, how can they climb? It turned out to be called Gastropoda. Every time it crawls, it secretes a mucus to help it crawl.
Snail is a small "vegetarian" and likes to eat bread crumbs, vegetables, fruits and so on. It usually moves at night, so I tidy its nest every morning and always find snails eating all the leaves. Does a snail have teeth? Tell you, there are, and there are more than 1000!
One day, I saw the little snail motionless in its shell and ignored me no matter how it touched it. I suddenly became nervous. Is the little snail sick? Or has it passed away? I looked up the information on the internet. Oh, it turns out that the little snail is asleep. In order to wake it up, put it in water, make its pores blocked and it can't breathe, and it will climb out. I tried, and sure enough, the snail woke up and climbed out. This is really interesting.
I like raising snails more and more, because I get a lot of knowledge and fun from it. Son, you can have a try, too!
Observing Snail Diary 2 I found a snail lying on the wall and a snail walking by the flowerpot in the garden today. I curiously put them in a glass bottle to observe. First, I poured some water into the bottle, and then I put a leaf in it to see their reaction.
Soon, the walking snail poked its head out of its shell, quickly climbed to the bottle mouth through the leaves and circled along the edge. Looking at this lovely snail, I have two questions in my heart: first, why do two snails behave differently, one is lively and the other is lying motionless on the wall? Is it scared? Second, why does it like to shrink in its shell and stick its head out only when there is water?
After careful observation, looking up information and asking my mother, I finally got the answer. It was originally shrunk in the shell, because it likes wet places, and its shell is wet. According to the data, in winter, snails will seal the shell mouth with a thin film formed by mucus and hide in it for the winter. Maybe this little snail on the wall just hibernated. And that lively snail is because her mother washed the garden and watered the flowers today. It must live in the soil of the flowerpot, so it climbs out for a walk.
At this time, the hibernating snail finally woke up and lazily put out its little head. It's like saying I woke it up. Through this interesting experiment, I learned a lot of interesting knowledge, and I will continue to observe it.
Today, I found a snail crawling slowly under a big tree. I was curious and took it home as a pet.
I put it on the table and waited for it to stick its head out. After a while, the little snail stretched out a little meat from the house. I thought it was very interesting and wanted to play with it, but when I touched it, the meat shrank into the shell.
"Snail, don't be afraid." I said, "Come out and play with me." But the little snail didn't listen, and there was nothing I could do, so I began to observe its shape.
The shell of a snail is spiral, like the horn of a bull. The middle is the drum, the color is the deepest, and it is brown. The farther it goes, the lighter it becomes. The outermost circle is khaki with a brown line on it, which looks burnt. I found a small hole in its head, which is its respiratory organ. The small hole is closed and opened for a while, which is really like a person breathing.
The wait is always long. I'm tired of waiting for the snail detector. At this time, the snail finally began to come out. I saw it squeeze a little meat out of the shell first, and I thought, what is this? Why is there a small sucker on it? After a while, I finally saw its head. It turns out that snails show their tails first and then their heads!
After the snail stretched out all its body, I found that it had two pairs of tentacles, one long on the top and one short on the bottom. There are two black spots on the top of the upper antenna, which are its eyes and its mouth in the middle of the lower antenna. A row of dots under the body is a powerful sucker.
The little snail straightened up, stretched out his tentacles and began to do morning exercises. It shook its tentacles for a while, then shook itself and began to walk.
The snail first held the upper antenna forward to see if there was any danger, and then touched the ground with the lower antenna to explore on the ground. Finally, he took a small step forward and repeated the action. After a minute, he climbed four or five centimeters forward. A silver line was left behind, shining brightly.
The little snail crawled for a while, then shrank back bit by bit, as if asleep. Sweet dreams, lovely little snail!
Recently interested in snails. Whenever I see snails on rainy days, I can't help but be curious and go up to observe their every move.
This time, I decided to report the whereabouts of snails in depth.
It was raining in Mao Mao in the morning, and the sky was hazy. I brought this umbrella and some plastic gloves downstairs. Downstairs, I saw several snails lying motionless drinking water. It is not too much to use the word "with relish" to describe it. I put on plastic gloves and my hands are itchy. I can't wait to put the snail far away from here and float away. Ten minutes later, I came back and found them gone? I was puzzled, and a question came to my mind: They came so slowly that they disappeared in ten minutes?
I am at a loss, floating around me like a confusing fog. I ran to where the snail was, but why is the snail still there? With a hint of disappointment and sadness, I was busy for an hour and got nothing. I was very discouraged, and when I was about to give up, I suddenly encouraged myself: "What if there are any skeletons in it?" I am like a dying candle, and suddenly I have a subtle light to see the freshness of snail fusion!
With these questions, I went upstairs to find out the truth. I leafed through books. After two hours of hard work, I suddenly realized that the snail didn't come quickly, but it was not in other places before it came, but in the surrounding fine grass. Because of the hidden terrain, it is difficult to distinguish the existence of snails with the naked eye. My second monk was puzzled and finally understood. My fire is brighter. Three hours have passed since the observation time, and the sky outside is already scorching sun, just like my mood.
When I came downstairs, I saw that a small number of snails were still struggling to crawl and crawling into the grass tirelessly. I thought of the knowledge in the book: snails in the sun will dry up in the abdomen, so I quickly put the remaining snails into the grass.
Yes, on the road of life, only persistent exploration can solve one problem after another.
Watch Snail Diary 5 In this week's science class, we will learn about snails. The science teacher took us to the school flower bed to catch snails.
The students turned over the stone in the east and moved the pot in the west. They were very happy to find it. Ah. I found them, but they seemed to lie there quietly, but in fact they were crawling very slowly. As soon as I touched it, it retracted its tentacles into its shell and hid it with its head. It was very interesting. I picked it up and put it on the ground. At first, it did not move. I guess it must be waiting for the danger to pass. After a while, it really began to perform. It first put its tentacles on its head and went out of the "house" to explore the news. When I saw nothing, I stuck my head out, then I had to get out, get up and crawl slowly, and a short and thick' tail' gradually stuck out of the' house'. At this time, I carefully observed the snail. It has a flat head, two eyes on tentacles, no nose and a short, thick tail, dragging behind the house. It always crawls with its house on its back. It looks more like sliding slowly, sliding here for a while and sliding there for a while, probably trying to find a suitable wet place to live. Maybe I'm looking for something to eat.
I am proud of my observation. The science teacher asked us to put snails in our own bottles, because snails live on vegetable leaves and are pests. If there are too many snails, vegetables will not grow well.
I went home today. I saw a snail in front of my house. I was so happy that I took it home and raised it.
When raising him, I found that there was a layer of mucus where the snail climbed, and the snail's tentacles would retract when it touched. If a snail is in the dark without water, it will retract its head. If it is put in water, it will retract its head. If it touches something, it will retract its head.
According to the teacher, this seems to be the pressure that biology should have. When a snail is stimulated, it will shrink into its shell. After a while, his soft body was almost invisible. I also found that the snail has two pairs of tentacles and a mouth. I'm sure he has vision because he can see food and eat it. My snail ate several leaves in a few days, which surprised me. I didn't know snails could eat so much!
Now I know that living things like snails are called creatures, and inanimate things like ordinary chairs and stools are called inanimate things, and I also find that snails crawl very slowly.
We should protect animals, but we can't hurt them, because we can't live without any kind of animals, so we should protect animals, not hurt them. Let's contribute to the peaceful coexistence of human beings and animals.
Today, the teacher arranged for us to observe the plants around us in our spare time, so after school, Yang He and I went to the grass, and we decided to observe snails.
We searched and searched in the grass and finally found a snail on an unknown plant. Its shell is spiral, a little yellow and a little black, and its body feels as soft as jelly and as sticky as glue. It has a pair of tentacles on its head like two branches. We take snails and plants home and put them in glass plates. We found it strange for snails to walk. It doesn't walk on its feet like other insects. It seems to walk with muscles. When it walks, it stretches and contracts. We found that the place where the snail walked left a silvery white mark, which was sticky to the touch. We thought: how can there be mucus? So, let's figure out why.
20xx rainy day on Sunday, June 27th.
We brought a lot of books and looked up information on the Internet. After summing up and analyzing, we finally know the answer to the question. It turns out that when a snail crawls, its muscle feet (feet) cling to other objects and make wave-like peristalsis, so it crawls slowly forward. Snails have foot glands on their feet, which secrete a viscous liquid to help them crawl. When this mucus trace dries, it will form a sparkling saliva line. Knowing this conclusion, we did two small experiments:
First, we put the snail on the glass plate and let it crawl. If we look under the glass plate again, we will see that the snail has no limbs and no feet, but its abdomen has wide or thin transverse folds, which are its feet and are called muscular feet.
Second, fix the snail on a dry board to prevent it from crawling. When the liquid it secretes dries, it will stick to the board and can no longer crawl like glue.
Observe snail diary 8 10, 12, Saturday sunny.
The teacher said he would go home to observe snails and give us a magnifying glass!
I finished my homework as soon as I got home. Maybe there is too little homework. I will finish it soon. I quickly took out the snail and put it on the ground. I saw it climb up slowly. I was afraid it would climb under the sofa, so I said, "Little snail! If you are good, I will call you' good'. If you are not good, I will call you' bad'! " I know this method won't work, but I'll try anyway! The little snail seemed to understand my words, stood motionless and waved his tentacles, as if to say, "Little master, I'm fine, please call me' dear' quickly!" I smiled and said, "Good boy!" "Darling" crawled around the table, so I picked up a magnifying glass and looked at "Darling". Darling's shell is left-handed. I heard that left-handed people are rare! Its body is soft and feels like chewing gum; "Dear" has four tentacles, two long and two short. The black spots on its long tentacles are its eyes.
65438+1It will be sunny on Sunday, October 20th.
On this day, I was idle and bored, so I picked up a magnifying glass to observe "Darling". Suddenly, a long, thin and black line appeared at the place where "Darling" excreted. Oh, dear! That's shit! I covered my nose and shouted, "Mom! Come here! " Darling "poop! First aid! " Mother picked up a paper towel, wrapped it around her hand, and unhurriedly caught the "darling" feces. I said, "That's disgusting! That's disgusting! Mom, you dare to touch it, you are so awesome! " "Catch yourself next time! Don't count on me! " Mom said impatiently.
In fact, the feces of "darling" are not very smelly, but why should I cover my nose?
One morning, I went downstairs for a walk. Hey, what's this? It turned out to be a large group of cute little snails. I carefully grabbed the smallest and most powerful one and took it home to ponder.
Less than half a day is burdened with a heavy burden, just like a collector carrying a treasure every day. It is reported that cattle have the most teeth in the world. There are more than 2560, as many as the stars in the sky. I can't count them. I looked at its mouth carefully, but I couldn't even find a tooth. It's amazing! It also has a distinctive tongue, because it has a whole sharp thing on it, so it is called "toothed tongue"
Small snails can crawl on ropes, leaves, leaves, etc. Just like a martial arts expert, he can climb the wall in name only, but he is also lazy. I remember once, I put it on chopsticks and told it to crawl. It didn't move, as if it were dreaming. The teacher told me that snails like to eat very rich foods, including juicy fruits, weeds, mollusks and so on. But the snail I caught is still very picky about food. I cut the pear into small pieces for it to eat. After a few days, the pear stopped moving, so I put the leaves aside. After a while, it was eaten clean.
By watching the sacrifice of snails, I learned a lot that I didn't know before, which also brought me happiness and stimulated my interest in raising small insects. I like small snails.
Observing the snail diary 10 After a heavy rain, I picked up a small snail in my yard. Suddenly, I accidentally touched the snail's antenna with my finger, and its antenna shrank back quickly. I think what's going on? So I put the snail on the leaves and took it home. When I got home, I couldn't wait to do the experiment and find out what was going on.
The first experiment: I put it on the table and observed its every move. At first, it lay motionless on the leaves. After a long time, it slowly sticks out its head and tentacles. It looked around as if it were looking for something.
The second experiment: I breathe gently, and its tentacles quickly retract into my head. Haha, that's fun. After repeatedly testing its tentacles, I found that no matter what the snail's tentacles touch, its tentacles will retract immediately, but I don't know why its tentacles retract.
The third experiment: in order to find out, I went to the internet to inquire about the relevant information. It has a pair of long antennae and a pair of short antennae, and there is a small black dot at the top of the long antennae. Those are snail's eyes, which are organs used to feel the external environment. Snail tentacles are like crutches for the blind. They are used to touch the road. When a snail walks, if it touches an obstacle with its tentacles, it will immediately change direction. However, the reason why it really retracts is to protect itself.
I finally figured out the reason why the snail's tentacles retracted.
Watch snail diary 1 1 I'm so happy today. Dad came back from Jinji Mountain and brought me a lovely little snail. I call it Xiao Q. I heard that this kind of snail can still be eaten, but I can't bear to give up, so I raised it!
Today is the first day to raise small snails. Let me touch its belly! It feels sticky and disgusting! But I'm not afraid. It's so cute to watch it crawling around on the wall of the water tank. I am very happy! Oh, I forgot if it was hungry. All right! Let my elder sister bring you delicious food, that is, vegetable leaves! Look at him eating vegetable leaves, how cute he is! I gently touched its tentacles, and it thought that there was a bad guy coming, and quickly hid in its shell to play! But unfortunately, something happened. I got up this morning and ran outside the balcony. I wanted to see it, but it was gone. I cried. I think, snail, don't die! I love you the most. Although it is difficult to get along with you for only one day, I love you very much, so don't go! Suddenly, I saw it behind the water tank, so I asked my grandmother to take it back to the water tank, but it was out of the water for too long and almost died. Please take it back, it's alive again!
After this scare, little snail, I will protect you in the future! Let you make this your home! I will take good care of you!
Watch Snail Diary12101It's sunny on Saturday, October 20th.
In the evening, I saw several snails crawling on the wall of the yard, and their tentacles kept swinging. I touched it with my hand and its tentacles shrank back immediately. How interesting! I decided to take this snail home and observe it carefully.
I put the snail on the table and watched its every move. I took a cabbage leaf and put snails on it. It didn't move. I waited by for a while, but it still didn't move. I thought: does it know that I am around and dare not move?
So, I ran out to play with my friends for a while, and then came back to watch. Ah, at this time, I found the snail's tentacles sticking out and crawling forward slowly.
I want to know the snail's crawling speed, so I stood by and waited for a minute, and then measured it with a ruler. Alas, snails can climb seven centimeters a minute. I also found that the place where the snail climbed left sticky marks. How strange! I ran to ask my mother, and my mother said, "Snails like to eat green leaves, especially vegetable leaves. And living in a humid place, the body is mostly water, so it will be like this. "
I put some snails in the box, added a little water and put a vegetable leaf on it. Ten minutes later, I went to see them again. Seeing the snails crawling around in the box, they finally climbed to the edge of the box. Oh, the snail tried to escape! I'll cover the box right away.
It is getting late. I'm going to bed. Goodbye, snail. See you tomorrow.
Watch the snail diary 13 It's sunny today, and the sky covers the earth like a sapphire.
The teacher assigned us a special assignment, that is, observing snails.
One of my snails is big and the other is small. The big one was particularly overbearing and took away the big territory. The little snail had to shrink aside.
In science class, Teacher Shi said that snails have 26,000 teeth, which amazed us. But snails are slow. If you take a step, it should be a hundred and eight thousand miles for it. Do you know where the eyes of snails grow? It grows on long tentacles. Do you know how many pairs of tentacles Wuniu has? Oh, you must say a pair. In fact, it has two pairs of tentacles, one long and the other short. Can you guess how snails use themselves to speed up? Snails spray liquid first and try to climb forward ... Snails eat a lot! Vegetables, apples, hamburgers and even meals. According to the data, if it eats food of any color, what color is its poop? How interesting!
On rainy days, when we observe ourselves, we will find a large number of snails on trees, leaves or grass, and we can conclude that it is going to rain. It is also very sensitive to humidity. If it is placed in a dry environment, it will find an environment suitable for its life.
Every day after school, I go to the balcony to see my snails and feed them. I feel very happy to see them grow bigger and bigger!
Observe snail diary 14 July 10 Wednesday sunny
When small snails eat, they like to start eating from the middle of leaves. It likes to eat young leaves best, and walks while eating, leaving a small hole behind with shiny mucus on it. Snails pull whatever color they eat, mostly dark green. Once, we fed it purple cabbage, and it pulled out purple poop. When it eats Chinese cabbage, it will have yellowish poop. Its neck can stretch very long, and its shell seems to be falling off. I'm worried about him.
On Saturday, July 20th, it was cloudy.
Small snails often escape from prison and always like to run out of the house and explore the outside world. Once it slipped out, and three days later, we found it on the refrigerator. He curled up in the shell, dry and motionless. Mother soaked it in water and it slowly woke up. Although it experienced a crisis of life and death this time, it still has an evil heart and wants to go out and explore the world. However, every time it climbed to the outer wall of the box, it was carried back by us.
1Saturday, October 26th 10 cloudy.
The little snail got into the soil, so we couldn't see where it was. Its shell is like a small stone buried in the soil, which is its protective color and is difficult to be found by natural enemies. Now that the little snail has grown up, he needs a deeper clay pot to bury it all in the soil.
165438+1It will be sunny on Sunday, October 3rd.
Now that the weather is cold, it will be winter. I wonder if the snail will hibernate? I am looking forward to it. I will continue to observe.
Observing the snail diary 15 One evening in summer, the sky had just rained and the air was particularly fresh. My mother and I came to the central square for a walk and felt very comfortable.
Walking, I suddenly found many snails lying on a stout tree. I was so excited that I quietly approached the tree and observed it carefully.
Some snails on the tree are big, some are small, some stick their heads out, and some retract their heads into their shells, all of which are firmly hung on the bark. I'm also worried that they won't fall. At this moment, I saw a big and fat snail crawling forward. The tentacles on its head are tandem, stretching with the crawling of its body, exerting great power. Snails crawl slowly. My mother and I have been waiting for 5 minutes. I haven't climbed a centimeter yet!
We watched quietly. After a while, I found a twig and tapped it gently. The timid snail shrank into its shell in fear, motionless, hey! Turned out to be a coward, I really want to laugh at it. In the blink of an eye, it quietly showed a nod from its shell and extended its tentacles with eyes to the outside. Maybe it felt safe, and then it boldly put its head out slowly. Oh! Too cautious!
It was dark, and we couldn't see the snail clearly, so we had to leave reluctantly, but the appearance of the snail remained deeply in my memory. ...
