I put the snail in a big basin. After very strict selection, four kinds of food were selected, namely: meat, tender leaves, vegetables and fallen leaves. I put different foods in different corners, but the snail didn't move and didn't cooperate with my experiment at all. So, I guess snails are not used to their new home, so they must adapt to it. The next day, I excitedly ran to the balcony to see it. I don't know, but I'm shocked. Most snails are eating green vegetables, and a few are resting under fallen leaves. After a long time, all the snails returned to rest under the fallen leaves. Because they have made this place their home. Scanning the whole basin with your eyes, when your eyes rested on the corner of the basin, you found that there were no snails on the meat at all. I wonder, don't snails eat meat? Then, I did another experiment. Reduce a little green vegetables every day to see if snails can eat meat, but snails still eat green vegetables. When there are no green vegetables, snails have to eat young leaves. When there are no tender leaves, they eat fallen leaves, but they never eat meat. Are they herbivores? With this question, I looked it up in the book. So snails are really herbivores! A glib tongue is good for eating green plants. I told my teacher about this discovery, and the teacher asked me to do more experiments. I have done several experiments about snails so far. Don't be idle, do experiments, and you will find many wonderful things.
Everything in nature is beautiful. As long as we have a pair of eyes that will discover, we will discover more unknown beauty.
Write a composition about snails (250 words later). Snails caught a snail near the school playground today to observe.
I found that snails have a pair of black eyes. I touched its left eye. Instead of retracting into the shell, it retracted its eyes. After a while, the snail didn't stick out his eyes. At that time, its eyes were white, and then they turned black. How wonderful this snail is! I carefully observed the place where the snail walked and found that there was some liquid in the place where it walked. This seems to be the liquid that the science teacher said, which can resist natural enemies such as ants.
Snails are great! The most striking thing about a snail is its shell. Don't think it's an ornament Very useful! As long as you pat the snail's shell hard, it will shrink into its "protective base"
Snails are great! Ah, snails are great!
What does snail like to eat? It has been raining these days, and the ground and walls are wet.
Finally, I waited until the rain stopped.
I went out for a walk with a happy mood.
I saw a little thing moving near the corner in the distance.
Looking closer, it turned out to be a snail.
I am very happy. After reading it for a long time, an idea came to my mind.
What do snails eat? I had a brainwave about this discovery and wanted to prove whether the result was true, so I decided to do an experiment.
Just when I want to catch snails, huh? Why is it missing? ! It turned out that I climbed it when I was thinking.
I went all out to catch a few home.
I put the snail in a big basin.
After very strict selection, four kinds of food were selected, namely: meat, tender leaves, vegetables and fallen leaves.
I put different foods in different corners, but the snail didn't move and didn't cooperate with my experiment at all.
So, I guess snails are not used to their new home, so they must adapt to it.
The next day, I excitedly ran to the balcony to see it. I don't know, but I'm shocked.
Most snails are eating green vegetables, and a few are resting under fallen leaves.
After a long time, all the snails returned to rest under the fallen leaves.
Because they have made this place their home.
Scanning the whole basin with your eyes, when your eyes rested on the corner of the basin, you found that there were no snails on the meat at all.
I wonder, don't snails eat meat? Then, I did another experiment.
Reduce a little green vegetables every day to see if snails can eat meat, but snails still eat green vegetables. When there are no green vegetables, snails have to eat young leaves.
When there are no tender leaves, they eat fallen leaves, but they never eat meat.
Are they herbivores? With this question, I looked it up in the book.
So snails are really herbivores! A glib tongue is good for eating green plants.
I told my teacher about this discovery, and the teacher asked me to do more experiments.
I have done several experiments about snails so far.
Don't be idle, do experiments, and you will find many wonderful things.
Everything in nature is beautiful.
As long as we have a pair of eyes that will discover, we will discover more unknown beauty.
I can sing the song "Snail and Yellow Bird" in the first volume of Grade Three, but I haven't seen a real snail yet.
On Sunday, my father came back from a business trip and bought me a small snail. I began to observe snails.
When I hold the snail in my hand, the first thing I see is the snail shell. Its shell is spiral, which protects its soft body.
When I looked at its shell, the naughty little snail poked its head out. It swings from side to side, very cute.
I found that snails have two pairs of antennae, one is longer and the other is shorter.
Those long tentacles are like two small antennas with two small points, which are snail's eyes.
I put some vegetables in my hand and the snail climbed over. I was just wondering what those short tentacles are for. They were originally used to help eat.
According to my father, snails have the most teeth in the snail world. It has 25,600 teeth.
I didn't expect the snail's mouth to hold so many teeth, too small to see! It's incredible! Snail's abdomen is soft, with some small spots on it. That's a snail's foot. That's how snails walk.
I did a little experiment.
Touch the snail's shell first and find that it doesn't respond.
As soon as I touched the snail's body, it retracted an antenna.
When I touch its tentacles again, it will retract them immediately.
If I touch its body hard, it will retract its whole body.
Dad said it was animal self-protection.
I took another piece of white paper and put the snail on it. After a few minutes, I found that the paper was wet and the snail couldn't take it off.
It turned out that the liquid secreted by the snail's body made it dirty.
I put the snail outside the small box containing it and turned the small box upside down. I was surprised to find that the snail turned and crawled back.
This snail is really a clever little animal! I like snails because it brings me a lot of happiness and knowledge!
What are the characteristics of snails? 200 words limit small snails I have several small snails at home, which were given to me by my mother on June 1st. Small snails are similar in appearance to river snails, except that their shells are brown. Some patterns of different thicknesses, yellow, black and white, run through it. Its body, sucker and head can be retracted into the shell. There are two pairs of antennae on the brown round brain, and one pair grows on it. There are two black eyes the size of a needle tip at the top. According to the book, snails have poor eyesight, so it's no wonder that they always shake their heads when looking for food, and only eat when touching food. In addition, it has a pair of tentacles under its head, and its function is still a mystery to me! Snails always stick out their long necks when they look up, a bit like giraffes! Connected to the head is a light brown body with a dark brown channel in the middle of the back. The color of the sucker is dark brown, and the surface is rough, like there is a layer of small sand on it. Snails have a very interesting life habit. They eat at night. I think it may be because they crawl slowly, are easy to be found by other animals, and are afraid of being delicious for other animals, so they come out to eat at night. Snails like dark and humid places. To this end, we put the snail in a flowerpot with wet sand and put it in a corner away from light. So, they keep their place and don't run around. They eat all kinds of food, such as cabbage, cucumber and noodles. Eating stick noodles is the most interesting. I mixed them into a thin paste, and they put their whole faces on it to drink. Soon, they became a big face. I change the sand once a week and give them a bath. Snails also bring me new fun. After reading this composition, we can really see these lovely little snails. It seems that the little author is still good at raising small snails. Look, how observant he is! What "eyes the size of a needle tip", "the surface of the sucker is very rough" and even "like dark and humid places" and "stick your whole face on it to drink" are clearly seen and introduced. Careful observation is the premise of writing a specific composition. Through observation, you have a concrete and vivid image in your mind, and then you can write something concrete by grasping the characteristics of things. Writing is realistic. This is exactly what the author did. It captures the characteristics of small snail, such as "the body, sucker and head can be retracted into the shell", "the crawling speed is slow", "like dark and damp" and "the food is very miscellaneous", and writes interesting stories about small snail, which really brings him fun. When writing this composition about the appearance and living habits of small snails, I used "the shape of small snails is similar to that of river snails" and "snails"
In the past, my "corruption" experience (full text) was that my father bought breakfast, and the breakfast my father bought was not to my taste. I propose to pay 70 yuan a week in the future, and I will buy breakfast. If I have any savings, it's my pocket money, so I can kill two birds with one stone. Father thought about it and agreed. I got 70 yuan the first morning. I bought fried eggs and tofu brain. When I got home, my parents ate happily, praised me for completing the task well and let me continue to work hard. Gradually, it came to my mind that if I bought cheap breakfast every day, wouldn't I save all my money? So, I had the idea of "corruption". Later, I got up early to buy breakfast, but the destination was a stall, where there were many cheap breakfasts and many goods could be handled with very little money. One day and two days passed, and no one raised an objection calmly, but on the fifth day, parents protested: "Why did you eat such a bad breakfast?" Not enough money? ... I don't know where to start, I can only get through it, and I can make a lot of goods with very little money? " When you write a composition, you feel blank. I said, "Why did you eat such a poor breakfast? I actually saved a lot of pocket money and made a lot of money. Then," Dad was helpless, but the composition was inexhaustible, and no one raised any objection, so Dad raided my pocket money-oh, it was my dad who bought breakfast. Don't you have enough money? Then you will find that there are too many words to write, which makes me "laid off" to reflect, and my parents have a good time! It's true that "paper can't wrap fire" If you forget your life, you might as well try to look back on your life and let me continue my efforts: "I don't sell fried eggs these days to write about" social corruption. " Some students write instead of writing. One day and two days have passed, which is an inexhaustible source and a little experience. I propose giving me 70 yuan a week. When I got home, I secretly laughed and I moved. " And interesting-"I" own story, but the destination is a stall. Looking back at those interesting stories that happened to me, not only are they true, but many students must have experienced them, so writing a composition will become very easy. This will kill two birds with one stone. Dad will go to the breakfast shop again, and I will buy breakfast, so I won't spend all the money I saved. If there is any savings in breakfast, it is my pocket money. It was not until the fifth day that I put myself in the position of "the protagonist of the composition". Alas, my parents protested. Later, I got up early to buy breakfast. I wrote down my life in the form of a composition. When my father believed it, there were many cheap breakfasts there. Finally, my "corruption" experience (full text) in the past, the store is still booming and living a "great life". So, because you neglected your own experience, you wrote a composition and tofu brain centered on "self" life. Dad wants to write a sample composition centered on your "self" life, and of course he forgets his own existence. This "corrupt" Xiao Si thought has been evaluated. Dad confiscated my illegal income, and the shops that have been buying poor breakfast and tofu brain for my parents are being renovated. I made a plan in my mind-
How to write the secret of a snail 300-word cow On Sunday afternoon, the weather was sultry. I walked into the yard and fiddled with my father's "baby flowers and plants".
Suddenly, I saw a snail slowly climb up the leaf.
"Snails are pests or beneficial insects? Why does it always leave a long line where it passes? Where are its nose and eyes? " A series of question marks came to mind.
I ran into the room and asked my father who was reading the newspaper. Father smiled and said, "since you want to know the secret of snails, why don't you experiment yourself?" Yes! Why didn't I think of that! So I decided to try it myself.
"Are snails pests or beneficial insects?" First of all, I tried to test turtles and snails with various foods.
I first picked up cabbage leaves, steamed bread, small mosquitoes, and then caught several snails, numbered them separately and put them in front of these foods.
Probably they were so hungry that they crawled to their favorite food, but each snail chose cabbage leaves and chewed them, but they couldn't smell other foods.
Soon, the leaves of cabbage were eaten up.
Now, I have come to a preliminary conclusion that snails are pests.
Then I conducted a second experiment to analyze why snails leave a long line when they crawl.
I grabbed the snail high. When its head stuck out of its shell, I tried to grab its body, but before my hand touched the snail, its head retracted again.
I think this snail is really a "coward"! I tried several times in a row, but I didn't succeed. I am really depressed.
At this time, my father came over and said, "I was discouraged at the beginning and wanted to be a scientist when I grew up!" " "I was so' excited' by my father and excited again.
Suddenly, an idea crossed my mind, "Yes, yes!" "I am dancing with joy.
I carefully cracked the snail's shell with a sharp stone, pulled out the snail's body and touched its bottom with my hand. I only feel some sticky, faint little things. What is this? I found the answer after consulting books. It turns out that the little thing is its feet, and the sticky thing is snail excrement, which helps snails crawl.
Finally, I want to see where the eyes and nose of the snail are. I put a cabbage leaf in front of a snail, only to see that the snail touched it with a pair of longer tentacles, then touched it with another pair of shorter tentacles below, and then gulped it down.
I think: probably one pair is eyes and the other is nose.
But which pair are eyes and which pair are noses? I took another leaf and another cabbage leaf of the same size and put it in front of another snail. Because the difference is not very big, the snail's eyes are useless: I can tell which one is a cabbage leaf and which one is a leaf just by touching it with my small antenna.
Now, I have discovered another secret: the big tentacle has the function of eyes, and the small tentacle has the function of nose.
Through this series of experiments, I really gained a lot: I not only discovered the secret of snails, but also understood a truth: if I want to make inventions when I grow up, I must cultivate the ability to find problems and learn to solve them from an early age.
-Sunflower used to sing a song when playing in the street: "What bird loves to run? What bird loves to sing? What flowers bloom in the water? What flowers look at the sun ... "Among them, the flowers looking at the sun are sunflowers.
Sunflower, also known as sunflower.
Why is it called sunflower? Just because the sunflower's disk will turn.
Every morning, as soon as the sun comes out, the disc faces the sun.
Sunflowers always face the sun from morning till night, no matter where the sun is.
This is probably the origin of its name.
So, why is the sunflower tray always facing the sun? I remember when I was a child, I heard a legend that several sons of the sun god took turns to be on duty in the sky.
One of the sons, feeling bored in the sky all the time, sneaked to the ground to play.
But once he came down from the sky, he couldn't shine. He involuntarily fell to the top of a small tree. Over time, he grew up with the tree and gradually became a sunflower.
At this point, he felt that the pie in the sky was still fun and regretted it.
I want to go back to the sky, but it is impossible.
From then on, he had to look at the sun brothers who were on duty in turn in the sky. Every day from morning till night, day after day, his eyes never leave the sun.
When I went to middle school and studied botany, I had a scientific understanding of why sunflowers always face the sun.
Botanists have found that behind the sunflower disk, there is a substance that has a particularly strong ability to distinguish light.
This substance prefers yin to yang. In order to avoid light, the front of the panel constantly changes direction and always follows the sun.
From this point of view, sunflower to the sun is not an act of god, but an instinct of life.
Sunflower is panicum miliaceum.
In the mature season, he is seven or eight feet tall, eight or nine feet tall, or even more than a foot tall.
There is a heavy golden flowerpot with the thickness of a cup on the stem. Against the fat sunflower leaves, it is really fascinating! Sunflowers, like most plants, are planted in spring and harvested in autumn.
Generally, the seeds are sown before and after the awn seeds, and the buds will break out in a few days.
At first, the bud only grew two pods, both of which were dark green.
The pod is thick, slightly oval, without any edges and corners, and the stem is smooth.
When it grew to more than a foot high, its appearance and color changed completely.
The previous dark green gradually faded.
Each new leaf has a tip, and the whole leaf is peach-shaped.
The stems are thick and short hairs grow at the same time.
At the top, there is a small bud.
At this time, as long as the water and fertilizer are suitable, it will grow up quickly.
In June and July, when a person grows to a height, it generally does not grow to a very high place. Leaves as big as a banana fan gradually turn yellow from bottom to top, but only the buds at the top grow up quickly, like a big disk.
The petals around the disk are golden yellow and full of energy, as if guarding the earth.
There are countless small yellow flowers in the flower tray, crowded together, but arranged neatly.
When the sunflower matures, the big petals and small yellow flowers gradually fall off.
Black sunflower seeds are exposed under small yellow flowers.
Sunflower can be enjoyed by people, but it is mainly a cash crop.
Sunflower seeds can be eaten or pressed for oil; Sunflower stalks can be used as fences. ...
A snail's life consists of 200 words. It looks like a small snail, but it is a little flatter than a snail. There is a "small house" on its back.
It is said that houses are used to protect themselves.
Therefore, it is no wonder that scalpers drag the house so slowly and so hard.
Snails are really interesting. As long as you touch it with your hand, it will shrink its head in fear and come out after a while.
At this time, if you look carefully, you can clearly see its eyes and tentacles.
Its eyes are small, dark, a little shiny and look very energetic.
A small tail sticks to the back of the house.
I usually like to eat vegetable leaves.
Every day after school, I always put the young leaves in their haunts. After a while, you will find that it has opened a hole in the young leaves.
The little snail is really interesting!
Write a snail-like composition, 150 words. There is a lovely little snail in my 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.
Snail composition 250, the uninvited guest of the school, came to the composition class in the morning and saw what everyone was looking for in the grass. I took a closer look, and it turned out that everyone was looking for snails, and I found them.
Soon I found a snail that climbed very fast. Its shell is black and round, very beautiful.
I named it Feifei, because there will be a competition later to see if snails can climb fast or not.
I hope my snail can climb as fast as flying, so I named it "Fei".
The competition was divided into two rounds, one round consisted of five people, and I was assigned to the first group.
The teacher asked us to draw lots to choose the runway, and I got the No.4 runway.
Before the game, everyone said that their snails could win the first place, and I was no exception, because I don't think my snails can really fly, but their speed should be "flying" among snails! The first round of competition has begun. At first, my snail was far ahead and climbed directly to the finish line. I jumped for joy.
Unexpectedly, halfway through the journey, Xu Longyue's snail caught up with amazing speed, and my snail began to run to the side. Wang turned his snail around and ran back. Wang said angrily, "This snail is crazy, and it doesn't matter before or after.
"The teacher helped me straighten the snail, and it ran away again. I hate iron and don't produce steel, so I said, "Hurry up and climb! "But the more worried I am, the more unhurried I am, but I finally won the first place.
The first one in the second round was Ba, who should have played in the first round, because the snail didn't give up! Snail race is really interesting!
On Friday morning, the rain stopped and there were many snails on the ground in front of my house.
I caught a male snail and a female snail. I named my mother Xiaobai and my son Xiaohei. I let Xiaohei and Xiaobai race on the table.
When the race started, "Xiao Bai" immediately rushed to the finish line and tried to escape halfway. I grabbed its shell and it immediately shrank into it. I'll put it down at once. It felt that the danger was gone and slowly came out of its body.
But' Xiaohei' is still sleeping at home.
Finally' Little Black' came out, and' Little Black' ran to the finish line, surpassing' Little White' and became the first in the competition.
I put Xiao Bai and Xiao hei on the door again. This time, Xiaohei didn't think about the shells, but climbed towards the finish line. He immediately surpassed Xiao Bai, and Xiao Bai did not show weakness and climbed towards the finish line. However, helpless Xiaobai struggled to climb up, but he still couldn't surpass Xiaohei. In the end, Blackie won.
The little black team beat the little white team 2-0.
So an interesting game is over!
Please indicate the source? What does snail like to eat? Observe that the composition is more than 250 words.
