Snail composition 1 After the rain cleared, a beautiful rainbow appeared on the horizon. I ran out of the house happily to see the beautiful rainbow after the rain. Walking, I came to the tree. The crystal beads of rain on the leaves, as well as a string of dripping rain, make a "tick-tock, tick-tock" sound, which is really nice to listen to, like a beating note.
Suddenly a crawling creature crawled slowly in front of my eyes. What is that? Curiosity drove me to find the answer. I squatted down and saw that it was a small snail, but it climbed so slowly. What can it do?
At this moment, my father stood beside me. He seemed to read my mind and said, "Although climbing is so slow, it is very useful. It can be used as medicine to treat diseases. " Moreover, the snail's shell is very hard, which can supplement calcium and protect the body from other animals. What can you think of to protect yourself from this? "
After listening to my father's words, my thinking accelerated instantly: mom and dad can protect me, but mom and dad also need protection. Of course, it is home that has been protecting us. Thinking of this, I said to my father, "It's a house. It turns out that our human house is inspired by snails! " "After listening to my words, my father said," That's right. The house can shelter us from the wind and rain and live a happy life, so home is a warm harbor in everyone's heart. "
Through today's observation, I finally understand that some unremarkable things can often give people a lot of inspiration. If you use your head and observe carefully, you will find more mysteries of nature.
Today, when my mother was shopping, she found a small snail lying on a vegetable leaf.
The snail's shell is very thin, and there are coils of ripples on it. That's the snail's little house. No matter where you go, the snail has to carry its house. You can't suffer all the year round. Its eyes are so small that it is difficult to find them without looking carefully. There are a pair of thin and smooth tentacles above the eyes, which are used to find the way. Snails always walk carefully, first looking for danger, if not, it will slowly climb out.
I picked up a vegetable leaf and began to observe how it ate. The snail seems very timid and refuses to come out for a long time. When I was impatient, I picked it up and accidentally found a deep gap in the leaf. The little snail is very picky about what he eats. Sometimes I give him yellow and rotten leaves, and he won't take a bite even if he is hungry.
I made a box out of cardboard, put the snail in it and let it crawl around freely. There is a white mark where the snail climbed, and there is some mucus on the mark. I touched it and said, hey, it's so sticky! Such as transparent glue. When I am free, I lie on the edge of the box and watch my snail quietly. Sometimes I can't help touching the snail's eyes, and it retracts its eyes. After a while, it stretched out again. It's incredible that a snail's eyes can stretch. So I went to ask my father, and my father said, "This is a way for snails to protect themselves. Its tentacles can also distinguish between roads and sounds."
In wetlands, snails lay eggs there as long as they see holes. Soon, the little snail hatched in the warm and humid soil and started a new life.
According to my mother, snails are wild. They have their own rules of life and can't be shut up at home. Although I didn't want to, I listened to my mother's arrangement and put the snail in the grass in the garden.
I discovered the secret of snails. One Sunday afternoon in summer, the weather was very sultry. I walked into the yard and fiddled with grandpa's precious flowers and plants. Suddenly, I saw a snail slowly climb up the leaf. Are snails beneficial or harmful? Why does it always leave a long line where it passes? Where are its nose, eyes and feet? A series of question marks came to mind. I ran into the room and asked my mother who was reading the newspaper. Mother said to me, 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 give it a try. Are snails beneficial or harmful? I test snails with all kinds of food. I caught five snails, numbered them respectively, and put some cabbage leaves, steamed bread and small mosquitoes in front of them. They are probably all hungry, and each climbs to his favorite food. Strangely, every snail chose cabbage leaves and chewed them. Soon, the cabbage leaves were eaten up by them. This can prove that snails are big pests! Then, I conducted a second experiment: Why do snails always leave a long line when crawling? I first caught its snail high, and when its head stuck out of its shell, I touched its big plate. But before my hand touched it, it shrank back and thought, you are such a coward! I tried several times, but nothing worked. At this time, I am a little discouraged, but I believe that there is nothing difficult in the world, nothing is impossible to a willing mind!
So, I got up my courage and suddenly a way flashed through my mind. Hey, by the way! I am dancing with joy. I carefully cracked the snail's shell with a sharp stone, took out the meat and touched its big plate with my hand. I saw something sticky and slightly small below. What is this? I found the answer after consulting books. It turned out that the sticky feet of snails at that time were snail excrement, which helped snails crawl. Then, I did the third experiment. I put a cabbage leaf in front of a snail, only to see it climb in front of it, touch it with its long tentacles, and then I ate it with confidence. I thought: which pair of tentacles are eyes and which pair of tentacles are nose?
I took out a leaf and a leaf-sized cabbage leaf and put them in front of another snail. This time, the snail's eyes are useless, only to see it climb to the front of the leaf, touch it with its short antenna, then climb to the front of the cabbage leaf, touch it with its short antenna, and then swallow the cabbage leaf. Now, I have discovered another secret: the longer tentacles of snails have the function of eyes, and the shorter tentacles have the function of nose. I have gained a lot through this series of experiments! I not only discovered the secret of snails, but also understood a truth: if you want to make inventions when you grow up, you should be good at finding problems and learning to solve them when you are young.
On Sunday, I played in front of my house and found three snails, so I caught them with a bottle. When I put them in the bottle, they will shrink into the shell, as if afraid that I will hurt them. After a while, they got out of the shell carefully.
The snail's shell is round with a circle of threads on it, just like the snail's house; The snail's body is very soft, and it has four tentacles on its head. Two tentacles with eyes are always upright, swinging like two TV antennas.
I gave them my favorite sausage, but they didn't look at it. I thought it was strange, so I looked it up online. Snails like young leaves and other green plants. I picked a vegetable leaf and put it next to the snail. The snail touches it with a big antenna, and then touches it with a pair of small antennas. Three snails swarmed in and devoured all the leaves. It turns out that this little snail has such a big appetite. What color do they eat and shit?
When a snail crawls, there is a layer of sea-like skin on each side of its body, and at the same time it secretes some mucus, leaving two very thin and wet marks on the ground. This is probably the mark left by a snail. If you can't find a suitable place to live, just follow this sign and go back to your original place to sleep. ...
I found this.
There are many lovely snails in the grass of the school flower bed. The science teacher gave us an assignment, which was to observe snails. I put the snail in a box and took it home for observation.
Snails are cute. It carries a shell, which is like wearing a hard coat to protect its weak body. Snails have two pairs of antennae, one long and one short, like two thin wires, and their eyes are as small as black sesame seeds. If you don't observe it carefully, you can't find its eyes. Its mouth is small, but it can't see its teeth. The science teacher told me that snails have more than 300 teeth. After careful observation, I found that the snail's shell is very special, not square or round, but spiral. Snails are really strange!
Snails crawl very slowly. It was a long time before it climbed a little. At this time, I was surprised to find that there was a white line where the snail climbed. I touched it curiously, and it felt a little sticky. What is this? Oh, it's snail mucus, so as not to slip when climbing. Snails can eat slowly. I put it on fresh vegetable leaves. When I finished my homework and went to see it, it ate a small round hole. It's really slow
The little snail is so cute!
Looking for Snails after Rain Geng Zhuoran, Class 4, Grade 4, No.1 Primary School, Huantai County, Shandong Province, has been raining these days. I think there must be many snails in the grass. I like snails! After class, I went to the small garden on campus and looked for these little guys in the grass.
Sure enough, I found a small snail as easy as blowing off dust. See how I catch it! I only touched its "house" with my hand, and this slow snail was "caught". In this way, I caught a dozen snails, big and small.
These little things are really interesting! When I gently touched it, it retracted its tentacles into its shell. After a while, it dared to stretch out its tentacles and crawl slowly. There will still be a line of mucus where it climbs, which is smooth and bright. I like to let snails crawl on my hands. Snails crawl on their stomach and feet, which are soft and make my hands itch.
These little guys are so cute!
