One day, I went to school early and walked to the school gate. Suddenly, I saw many people looking around a shop. I think it's strange. Take a closer look, it turns out that everyone is rushing to buy silkworms!
After seeing this situation, I decided to buy some silkworms to feed after school. After school, I happily bought four silkworms and several bags of mulberry leaves. After I bought it, I went home humming. As soon as I got home, I immediately opened the box and watched my silkworm gnawing mulberry leaves. I am very happy. I hope my silkworm will grow up soon. Since then, I have helped him clean up his feces and fed mulberry leaves every day. When mulberry leaves are not enough, I buy them for him. In this way, after a week, my silkworm finally grew up several times!
Later, I was going to observe the process of eating mulberry leaves. The observation began. I waited for it to finish eating a mulberry leaf I put two hours ago, and then I put another mulberry leaf in it. After waiting for a few minutes, a silkworm quickly climbed over to eat mulberry leaves. I found that sometimes when it can't eat them, it will move forward with its mouth wide open. As soon as it bit the mulberry leaf, it ate it. Then the other three climbed over and ate together.
I found that sericulture is not only as simple as feeding it mulberry leaves, but also can bring you a lot of happiness. I expect silkworms to break their cocoons quickly and become moths.
Observing Silkworm Diary 2 Because I showed some friends in my class photos of my silkworm yesterday, it immediately caught their attention, and they all came to my house to have a look. After my classmates left, I prepared a small box and decided to raise silkworms independently. And compare with dad to see who raises it well. It seems that our sericulture activities will be upgraded.
In addition, my father's silkworm has changed a little today. The longest silkworm is nearly 6mm, and it can be seen from the small hole bitten by mulberry leaves that they eat a little more. On the spur of the moment, I chose a big one and a small one and asked for my support.
After a while, I wanted to raise another one, so I moved the silkworm baby independently. First, I touched the mulberry leaf with my hand. If I can't get it off, I'll put the silk aside. I took the silk in my other hand and lifted it with my hand. I will look at my father's silkworms. The larger silkworm baby looks whiter, like a layer of gray, so it is easy to distinguish three "age" segments of the silkworm baby from the color-the lightest and slightly stronger silkworm baby is older; Silkworm babies with gray heads and black bodies are younger; The smallest silkworm is black and looks thinner. The emaciated father silkworm got special care-the young leaves were picked and put aside alone. When they are stronger, they will be raised with the old silkworms.
Today, I brought back some guests from school. These guests are really interesting! They are silkworms.
As soon as I got home, I quickly found a new home (actually a shoe box) for these silkworms and carefully put them into their "small home". They all seem to like the little home I installed for them. When they went in, they looked around and crawled around on the mulberry leaves.
My silkworms are very interesting. One of them is the oldest, which was given to me by my classmates. And nine little silkworms, just bought. Mother was afraid that the big silkworm would bully the little silkworm and asked me to put the big silkworm in another box. I was afraid that the big silkworms would be too lonely, so I put them together. The big silkworm danced as if thanking me: "Don't worry, I won't bully my little brothers."
They are very cute, with many feet and gray clothes. It's fun to get up. Go forward, I have never seen such a move, and I can't help laughing. They eat in a more unique way, always biting into their mouths. Still on a leaf, wear it back and forth until this piece is completed. Mulberry leaves are covered with small holes and tooth marks left by them after eating. composition
Observing the Silkworm Diary 4 Spring will arrive before you know it! Her arrival also gave life to a beautiful bug.
That's a silkworm. I have silkworms, too
In the spring sunshine, some small creatures were born in the silkworm eggs. They are all black and ugly, very ugly. Grandma told me that this newborn silkworm is called ant silkworm. Because just born, the body is very small, especially like ants, so it is called ant silkworm. The newborn ant silkworm greedily ate the mulberry leaves I put in the box. As if growing up overnight!
Next, after several molts, the silkworm grows up, its skin turns white and its body becomes the size of a finger. At this time, silkworms are white and fat, and they become very attractive. Grandma told me that silkworms at this time are called adult silkworms.
About 40 days, silkworms began to spin silk! It first found a triangular bracket, then spun silk and fixed it, and began to cocoon. A few days later, the silkworm wrapped itself in its "small room". Cocoons are colorful, mostly white and yellow cocoons.
Silkworm's life is short, but it is meaningful. This reminds me of the poem "Spring silkworms will keep spinning until they die". The moth that came out of the cocoon gave birth to the seed and died. No one can understand why silkworms end their lives in such a tragic way.
Silkworm! I love your life! From then on, I thought, our life must be meaningful! So we won't live up to our parents' expectations! Will make due contributions to society!
Observe the sericulture diary, it will be cloudy on Saturday, May xx.
Today, my father helped me buy dozens of silkworms from the street and asked me to keep an observation diary. I pack silkworm babies in boxes. I was afraid they would shit, so I specially put some paper in it, which is sanitary and can keep the box clean at any time. It really has two purposes. The little silkworm in the box kept eating delicious mulberry leaves with its hungry mouth, as if it would never be enough. The silkworm's body has 10 segments, and each segment has four legs. Small eyes show a desire to be a moth. My father said to me, "It seems that I will bite and peel off my skin next Wednesday.
It turned cloudy on Tuesday, xx, xx.
This morning. I looked at the silkworm and found that the silkworm didn't eat or drink, lying on the side with a depressed face. I thought: will it get sick? So I quickly woke up my sleeping father. He opened his sleepy eyes and said impatiently, "I told you that silkworms are molting today." This phenomenon is normal. " Then I went to sleep again. I went to school happily, thinking: I should be able to see the cocoon peeling at noon. When I came back at noon, I found that the silkworm was eating mulberry leaves happily again. I looked at it as before, thinking: will it grow up after peeling? With this question, I asked my father, and my father affirmed my idea: a silkworm must shed its skin xx times in its life, then become a cocoon, and finally become a moth. During this period, silk that becomes cocoons can be used to make quilts and clothes. Moths will die after laying eggs. Children, you must learn the spirit of silkworm's silent dedication to mankind, which is called spring silkworm weaving until death. "
Yesterday morning, our classmate's silkworm baby box arrived at the station, and the classmates were ecstatic.
When I came home yesterday, my silkworm baby Huanhuan walked a tightrope on the mulberry leaf pole, walking like a professional actor. Silkworm baby "Qingqing" is rolled together like a snake and looks a little disgusting. "Xiaojing" crawls around on the mulberry leaves, busy as hell, and sometimes comes down to eat something delicious. Baby Silkworm "Yuanyuan" is a greedy cat. She eats all day and her stomach is bulging, so she is called "Yuanyuan".
Today, I did an experiment. Can silkworms hear? In the evening, I asked my father to turn on the "Thousand Listeners". I opened the silkworm box and there was "That Night" on the loud stereo. Two or three silkworm babies looked up as if to say, "What are we listening to?" Do silkworms really have hearing? I played it again, but the silkworms looked up at me and listened curiously ... what an anecdote! After a series of investigations, I think silkworms have hearing. Believe it or not, do the experiment yourself.
Tell you a news, a silkworm (Qingqing) has shed its skin, and its skin is brand-new and smooth!
Observing the Silkworm Diary 7 There is an ancient poem that says, "Silkworms in spring must spin until they die, and the candles should dry the wick every night." Silkworm's life is the greatest. It devoted all its silk to human beings all its life, but lost its life. Can't you say great? In a science class, I handed out several silkworm eggs.
A few days later, I found that a few little things like ants bit through the silkworm eggs and crawled out of them. Hey, what's this little thing? I thought it over for a while. He looks like an ant. It should be the ant silkworm that the teacher said. I took some mulberry leaves and cut them into small pieces. Under my careful care, the ant silkworm slowly grew to three years old. I'm happy and sad. What makes me sad is that they have reached middle age and are about to leave me.
To my delight, I no longer need to observe silkworms with a magnifying glass. You can see them clearly with the naked eye. Silkworm has three parts, chest and abdomen, and there are several small black holes in the abdomen, which are all respiratory organs of silkworm. There are four pairs of furry feet near the silkworm's head. They all help silkworms eat food. If you observe the silkworm day and night, you will find that it eats mulberry leaves day and night, and it is a veritable "big stomach king".
Calm down and listen to the silkworm eating mulberry leaves, and you will hear the rustling sound. Silkworms eat mulberry leaves in an arc. Silkworms shed their skin six times in their life, and then undergo metamorphosis, and finally they cocoon into moths. This is my observation of silkworm life.
Observe the sericulture diary 8 "Ya ga ga ga, the mulberry leaves are finished so soon!" "I exclaimed when I finished my homework and went to the corridor to see silkworms! At this time, the cage was a mess-the little silkworm was discontentedly crawling on the bare branches, and the feeding box was full of broken mulberry leaves, and there were many disgusting things-little silkworm droppings!
Seeing the starving silkworm, my father and I sighed and ran to the abandoned garage next to the reservoir of the street police station under Central Street, where there was a big mulberry tree. My father and I picked a bag full of mulberry leaves and came back with a full load.
The next task is to clean up the rearing box for silkworms. I think this is the dirtiest, smelly and tiring job in the process of rearing silkworms! Cover your nose, open the feeding box, and a foul smell comes to your face. I coughed twice, trying to tear off two small silkworms tightly attached to two mulberry leaves. "Brush ~ ~" Silkworm was pinched away by me, but its feet were still attached to mulberry leaves. I was in such a hurry that I had to take them out with silkworms and leaves.
Then, I poured out the remaining broken mulberry leaves and poop. "Wow, it stinks!" I pinched my nose. It turns out that working for young silkworms is so tired, so dirty and so smelly! I quickly patted myself for fear that the smell would stick to me.
Finally, I picked many of the biggest mulberry leaves, carefully laid them in the box, and put the young silkworms back in the box. Ah, finally!
It is not easy to "work" for young silkworms!
Observation of Silkworm Diary 9 Silkworm is an interesting animal. Its head is round, its eyes are small, its body is fat and lovely. Silkworms have many functions. Silk can be used as towels, clothes, quilts and so on. Silkworm dung can be used as a pillow and silkworm moths can also be used as medicine! It seems that silkworms have so many uses! Covered in treasures.
Today, my uncle took me to the countryside to play. We came to a relative's house. I saw many silkworm babies in my relatives' house. Oh! It turns out that relatives also raise silkworms. My grandmother told me that silkworms pick a lot of mulberry leaves every morning. Silkworm babies eat a lot, and the mulberry leaves they eat are required to be fresh, so it is very hard to pick a lot of mulberry leaves and clean up the house every day. "Hey? How can the silkworm baby spill some white things? What is this? What is it for? " When I first walked into the silkworm house, I vomited a lot of questions. "The white one is lime powder, which is used for disinfection, otherwise the silkworm baby will get sick." "Oh, so that's it! ..... Then will lime powder be fascinated by the eyes of silkworm babies and harmful to them? " I thought of another strange question. Grandma smiled and said, "You really know how to ask questions, but I can't answer this." I am determined to study hard and solve this problem in the future.
Looking at the silkworm plaques all over the room, it is estimated that there are thousands of silkworm babies. Silkworms have a hard time raising so many silkworms. We must cherish the happy life now!
"Spring silkworms must weave until they die." Silkworm babies' hard-working spirit of paying for human beings without asking for returns and the unremitting efforts of silkworm farmers are worth learning.
Observe the diary of silkworm baby 10 My silkworm baby is very fat. When grandma came back from a business trip, my mother and I were surprised to find that the silkworm baby suddenly grew up a lot and ate an amazing amount of mulberry leaves, and could eat a lot of mulberry leaves a day. It seems that everyone who grows up is hungry!
Last night, I was surprised to find that the shortest and thinnest silkworm baby actually started spinning cocoons. Later, I remembered that when I went to see them at noon yesterday, the silkworm baby just held her head high and looked around. It turned out that it was looking for a place to make cocoons. Silkworm baby is so clever. It found a corner of the box and began to spin silk, because there was a place to climb. I asked my grandmother to come and see, and she tore a small piece of rice paper and leaned on it. I asked my grandmother what it was for, and she told me that it could form a triangular support between the rice paper and the corner of the box. She also said that it would be nice if there was a straw.
As soon as I got up this morning, I couldn't wait to see the silkworm baby. I saw that the cocoon had formed an oval ball, and I found a baby silkworm cocooning beside it. Yesterday, I also put a piece of rice paper in the other corner of the box as grandma said, and the silkworm baby also used it. I'm so happy. I saw the silk spit by the silkworm baby shining in the light.
I wonder what the cocoon of the silkworm baby will look like tomorrow? I am looking forward to it!
