The day is coming to an end, and there must be a lot of feelings in my heart. Let's keep a diary together. So what problems should we pay attention to when writing a diary? The following is my carefully arranged observation diary of silkworm babies, hoping to help everyone.
Silkworm Baby Observation Diary 1 A month ago, I got a special "gift" in Chinese class-Silkworm Baby. After I got these little silkworm babies, I had a lot of questions in my heart: how do they eat? How do you shit? So, I made a careful observation with these questions.
Silkworm baby looks very cute. Its body is as long as a big potato chip, but its head is only as big as a grain of rice. It has two pairs of black patterns like brackets on its back, probably to scare natural enemies. But after peeling, the bracket is gone, and it will take a few days to recover.
It has a small thorn on its tail. When it is in a bad mood or hurt, the small thorn will soften. Silkworm babies have three pairs of chest feet, four pairs of abdomen feet and a pair of tail feet. Its belly feet are used to fix itself, its tail feet are used to hold things, and its chest feet are its real feet, which are used to help it catch food and facilitate it to eat. When you grow up, you will lose your belly and tail feet and become an insect with only three pairs.
The way silkworm babies eat mulberry leaves is very interesting. It first grabs mulberry leaves with its chest and feet, and then raises its head. Like an excavator, it sends mulberry leaves to its stomach in an orderly way from top to bottom again and again. After a while, a mulberry leaf disappeared.
I also found another strange thing when I was raising it: the stool it pulled out was about the same size, like sesame, black and small, solid but a little elastic, with patterns like corn on it. I took a look and found that it was full of mulberry leaf foam undigested by silkworms, and there was a fragrance.
Through so many days of observation, I found that silkworm babies are really selfless. It has worked hard to eat mulberry leaves all its life, just to spin cocoons and let us have warm clothes and quilts to enjoy. I finally understand the true meaning of "Spring silkworms must weave until they die".
Silkworm baby observation diary 2 The silkworm baby I want from my sister is like a little ant. After my careful upbringing, I grew up gradually, and now I am as thick as pencil lead.
When they were young, I couldn't see clearly how they ate mulberry leaves. After they ate and crawled away, they found that the thin layer of skin on mulberry leaves was gone. Later, when they grow up a little, they can observe that they chew mulberry leaves from top to bottom, that is, they feed themselves slowly in the repeated process of raising their heads and lowering their heads.
So far, my silkworm baby has been skinned twice, from black to gray now.
I remember the first time (from:: Observation Diary of Silkworm Baby) they peeled off their skins, and they didn't move. I thought they were going to die. I was so anxious. Later, my sister told me that she might be unable to move because of peeling. Sure enough, I woke up the next day and found black spots on mulberry leaves. Sister said, "Silkworms grow up when they shed their skin."
One day, I went to see the silkworm babies and found that they didn't move again, and the mulberry leaves only ate a little. I wondered if it was time to peel again, so I quietly observed them and found a silkworm baby lying on its side. When I helped him straighten up and lie down, he wriggled and crawled, and slowly found his body bulging, and then the skin at his tail peeled off bit by bit. How could he not come down? Suddenly, my sister came out from behind me and said, "No."
Move it "and say it will take off on its own. At this time, the silkworm baby began to swing from side to side, and finally shed its skin through its own efforts.
Silkworm baby observation diary Thursday, March 30 th is cloudy
I bought five silkworm eggs today. They are round, golden and lovely! The sun shines on them, and they look more like golden gems.
It rains on Tuesday in May 10.
Today, I found that silkworm eggs began to become bigger and more transparent. Slowly, a small hole appeared on the egg, and a black mass climbed out of it. What is that? Why is it so small? Let's look at it with a magnifying glass. I think, take a photo with a magnifying glass. It turned out to be a silkworm baby. Why is it so small? It is still black, like a slender black line. I gently swept the ant silkworm onto the mulberry leaves with a brush. I saw the ant silkworm slowly climb to the edge of the mulberry leaf, clutching the mulberry leaf tightly with six tiny feet, for fear of falling, but it had a great appetite. In the blink of an eye, a piece of mulberry leaves will be done.
Friday, May 13 will be sunny.
One of my silkworms doesn't eat or drink today. I think it is going to cocoon. Sure enough, after a while, Silkworm Treasure began to spit cocoons in the corner. It first weaves silk into a net, then into an ellipse, and finally into a peanut-like cocoon. This cocoon is pure white. From a distance, it really looks like a silver diamond, shining.
It will be sunny on Monday, April 20th.
My three silkworm moths have broken out of their cocoons. There are two women and one man. The newborn silkworm moth needs to be white all over, and her chubby body has a pair of light wings. Female and male silkworm moths have different wings, the female is small and the male is big. Although they have wings, they can't fly because they are too heavy. Although they can't fly, their wings look beautiful. A pair of snow-white wings, sipping brown-gray patterns, are very beautiful. There is something like a beard on the nose of a silkworm moth. It looks like a hunchback grandfather with a pair of brown-gray beards. This is very interesting.
Silkworm baby observation diary 4 I once had a silkworm baby, all black and white. When I first got it, it was only 1 cm long, like a little caterpillar. I gave it mulberry leaves, and it ate this piece and that piece for a while, as if trying to taste which mulberry leaf was better! I just defecate while eating, which makes me sick. I found that its stool is black, cylindrical and about the same size, and it is still hard and can't be crushed by pinching. When I went to see it at night, there was a large piece of mulberry leaves next to it!
The next morning, when I went to see the silkworm baby again, I found that all the mulberry leaves beside me were gone. What happened? Doesn't it sleep at night? So, I finished my homework early that night and went to observe the silkworm baby. I found that it stopped moving after eating for a while, and stopped moving after eating for a while, ah! I see, it is different from us. It eats and sleeps for a while, and we eat and sleep for a while.
A few days later, I found it motionless. I thought it was dead, but I didn't like it. It stayed motionless for two days. Two days later, I went to see it again and found a brown thing in the box where it lived. When I looked carefully, it turned out to be its skin. I also found a silkworm baby hiding aside. Its body turned yellow, but it didn't get bigger at all. I feed it mulberry leaves every day and help it clean up its stool. It starts to get bigger and bigger, and its body turns back to its original color.
After about two weeks, it began to spin silk and hid in a corner of the box. Its silk is yellow, and it cocooned in a few days. It stayed in the cocoon for less than four weeks and then crawled out. At this time, it has become a fat moth, but it still doesn't eat or drink.
After two or three days, it began to lay eggs. It lays hundreds of white, yellow and black eggs. After it laid its eggs, it died slowly.
By raising silkworm babies, I learned the growth law of silkworm babies and how to raise small animals.
Silkworm Baby Observation Diary 5 Today, the teacher assigned a special assignment-sericulture. So I hurried to the market to buy some silkworm eggs.
Silkworm eggs are very small, just like small sesame seeds, black and black. The shape of an egg is oval. It seems that it will be crushed to death by a light press. I dare not touch it. I carefully picked up an egg and observed it. I don't even dare to go out in the air, for fear that I will crush them into a paste when I exert myself.
After a while, I went to see them again. I was very surprised. Silkworm eggs become translucent sesame seeds. I didn't dare to be careless, so I squatted down and observed them gently. Some small silkworm eggs poked their heads out and looked at this brand-new world in confusion. Some looked around curiously and some were at a loss.
Small creatures have been born in this world, and it is hoped that the small silkworm eggs with stars and the moon will eventually hatch out. One by one, the silkworm babies put on black clothes and came out of the eggs. Silkworm baby wants to eat mulberry leaves, so I quickly went to the market to buy a bag of mulberry leaves, cut them into small leaves and put them in front of silkworm baby.
A week later, the silkworm baby who was originally dressed in black took off his black clothes and put on a white coat. Silkworm babies become chubby and become chubby "small white faces". Since then, their appetite has greatly expanded, and they have to eat four or five meals a day from morning till night. Contact for a long time, I also know the law of their eating mulberry leaves. They eat from the side first, then slowly eat from outside to inside, making a rustling sound. Their mouths open and close, very cute!
America is wrong. My little silkworm has shed its skin. It has three feet. It has a small hook on its abdomen and foot, which firmly grasps my hand like a "sucker". There are two round noses on both sides of each section with crescent points on them.
When the silkworm baby is about to spin silk, his body is a little yellow, and the silk inside can still be seen on his chest. It spits out the Z-shaped silk first, and then firmly surrounds itself.
This is a silkworm baby. Do you understand from my description?
Instructor: Miss Wang.
Comments: The little author introduced the life of silkworm baby in detail through delicate and vivid observation, and grasped the different characteristics of silkworm baby at various stages to write, which was great!
Silkworm Baby Observation Diary 6 Today, the school teacher gave each of us several silkworm eggs, which were very small and black like black sesame seeds. The teacher said, "Take your silkworm eggs home and cultivate them well. When you grow up, take them back to school and compare who looks the best and who is the healthiest. " I went home with excitement and excitement. When I got home, I immediately installed a comfortable little house for the unborn silkworm baby. I've been staring at it, expecting it to be born soon. Sure enough, after a few days, the silkworm baby was finally born. How lovely those little creatures are!
On Saturday, June 20th, 20xx, I go to the park to pick mulberry leaves every day. My silkworm babies are all big eaters! You can eat one or two mulberry leaves every meal. Looking at their chubby little bodies every day is very happy. With growing up day by day, a silkworm baby, her figure is getting bigger and bigger. One morning, I was surprised to find that my silkworm spun silk! White silks are interlaced with each other, and it seems that they are all surrounded by silk. I was so excited that I called my parents to watch it together. They were all surprised. My father also praised me and said, "Subkey, you have raised it well!" " Silkworms are cocooned and healthy! "On Friday, July 5th, 20xx, the weather was fine, and it broke into a butterfly. Although the silkworm no longer needs to be fed, I still stare at it every day, hoping that it will break its cocoon and become a moth soon. A few days later, I found that the cocoon finally moved and everything paid off. I stared at it until it broke down. Its wings first break out of the cocoon, and then its body moves out step by step. At the moment when the silkworm moth really broke out of the cocoon, I finally understood the truth of breaking out of the cocoon: no matter what difficulties we encounter, we must have persistent spirit and tenacious perseverance in order to achieve real success.
The neighbor sent two silkworms, one of which was white, oval and the thickness of an adult's thumb. The other one showed signs of cocoon the next morning and was busy looking for a suitable place. Finally, I spent a day and a night cocooning in the "house" built by my daughter. Before going to bed at night, my daughter was still observing the activities of silkworms in the cocoon under the light, and she kept spinning. So I can "sleep" safely at home. A few days later, my children and I cut open the hard cocoon and found that the silkworm had turned into a pupa, and the shed skin was beside it, stroking the body of the pupa gently. It twisted its abdomen, and its color was no longer milky white, but yellowish brown, with a deep back and a shallow abdomen. We quickly put it back, thinking that it would "turn into a moth"
I always regret that my daughter didn't observe the process of feeding silkworms. Unexpectedly, on July 3rd, my friend sent me 1 1 silkworm baby again, and my daughter was very excited at once. She picked mulberry leaves, washed them, dried them, fed them and observed the growth and changes of silkworms. I also helped her to set up observation files, so that she could record and observe them better and cultivate her interest and methods of research.

My silkworm moth broke out of its cocoon. I saw that the silkworm moth drilled a big hole in the cocoon, and there was dark brown skin in the hole, which was the faded skin of silkworm chrysalis.
Silkworm moth has a fat body, short wings, two tentacles, two small eyes and six feet.
Some silkworm moths are still in place, some are spinning in place, and some are laying eggs! Some of these eggs are yellow, some are white, some are on cocoons, some are on cartons, and some are on paper.
I want to collect these silkworm eggs and hatch them into silkworms next year.
Two weeks ago, the science teacher gave the silkworm babies to the students to raise. I took the silkworm baby home and counted it. There are six.
Silkworm baby is gray, only as thin as wire, about 3 cm long, with a small air hole on both sides of its head. I found a short and soft thorn on its tail. It has three opponents under its head and four pairs of feet in its abdomen. Although it has so many hands and feet, it still crawls very slowly.
It eats mulberry leaves very fast and soon chews out a big hole. I put my ear close to it, and when they eat mulberry leaves, they will make a rustling sound. I found that silkworm babies can't live without fresh mulberry leaves for a moment. I held the silkworm baby in mid-air, and he shook his head as if to say, "Put me down, I want to eat mulberry leaves!" " "I put the silkworm baby back in the box, and it enjoyed its delicious meal on the mulberry leaves again.
A week later, I found a yellow, wrinkled and dry thing next to the silkworm baby. I picked it up and saw that it was the skin shed by the silkworm baby. The molting silkworm baby becomes bigger and whiter. I measured it to be 5 cm long.
Silkworm baby is really an interesting and naughty little animal!
I bought 20 silkworm babies and two bags of mulberry leaves at school this spring.
When I got home, I carefully observed the silkworm baby with a magnifying glass. They are all black and have two pits on their heads. At first, I thought it was the eyes of a silkworm baby. Later, I saw the silkworm baby eating mulberry leaves a little, only to know that it was the silkworm baby's mouth. A little silkworm has fourteen feet, six on its head and eight on its body. They are so small that I dare not touch them with my hands. Afraid of hurting them. Some silkworm babies always climb out, so I sweep them on the mulberry leaves with a brush.
After a few days, the color of the silkworm baby gradually turned white, and there were some strange things in the carton. I'm curious, does it have the function of changing color? I looked it up on the internet, and it turned out that it didn't change color, but shed its skin and turned white. Those strange things next to them are their molting. As they grow up, they eat more. Every time they finish eating the mulberry leaves in the box, they turn their heads away, as if to say to me: Where are the mulberry leaves? Don't feed us mulberry leaves, do you want to starve us?
Gradually, their bodies turned yellow and they were very weak. Not as active as before. I was so worried that I thought they were ill. I just checked on the internet and realized that they were going to spin silk. They spun silk in the corner of the box and wrapped themselves up. After a while, I found something moving in the cocoon, only two cocoons broke a small mouth, and then a silkworm moth climbed out of it. Slowly, all the cocoons broke and all the moths came out. I saw silkworm moths mating in pairs, and then they laid a lot of eggs. Silkworms die slowly after laying eggs.
Silkworms spin a lot of silk for us. Let's make clothes. This spirit of selfless dedication is worth learning.
