There is an ancient poem in the silkworm observation diary 1: "Spring silkworms will weave until they die, and they will weep 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 sound of "rustling". 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.
Silkworm Baby Observation Diary 2 On Friday, the teacher asked us to write a weekly diary of my silkworm baby. I thought to myself: With so many silkworm babies at home, it must be handy to write.
A month ago, I took out the silkworm eggs left at home and wrapped them in cotton. A few days later, a black spot appeared on the silkworm eggs. A few days later, the little silkworm came out. This is an ant-like thing. I thought it was rubbish, and I was going to throw it away. My mother said loudly, "Don't throw it away, it's an ant silkworm!" " ""what? Ant silkworm? "I don't understand. Mother said, "This is the silkworm baby who just came out. We call it ant silkworm. "
Another week passed, and the silkworm baby grew up a lot. His body is soft and his head is black, which is smaller than his body. His mouth is a small hole with two front teeth. It eats mulberry leaves. There is also a small hole in the middle of the head for rotation. It has eight pairs of feet and walks arch by arch, which is very interesting. One day, I saw the silkworm baby staying in the corner, motionless. I thought it was going to die, so I quickly called my mother and said, "Mom, the silkworm baby is not moving!" " "Mom smiled and said," it's not dead, it's peeling! "Really?" I'm a little skeptical. Mom said, "If you don't believe me, you can see if it will come out." After waiting for several hours, I found a hole in the shell of the silkworm baby, and the silkworm baby climbed out of it. "Come out! Come out! " I cried happily.
After a few days, the silkworm baby shed its skin again, and now its whole body is white. It's really some bombshell-like love silkworm babies, who should change clothes occasionally like us girls!
I really hope that the silkworm baby will grow up carefree under my care!
Silkworm observation diary 3 Today I'd like to introduce you to the silkworm boss.
But before I could have a closer look, it got into its own "small mosquito net". Her "small mosquito net" is yellow, very beautiful! It's different from other silkworms. It is said that the color of spun silk is different because of different genes.
Silkworm boss is very fat He got into the cocoon and pulled it very big, which was the largest of the four cocoons. Its cocoon is like a floating sunset glow in the sky, shining in the light, very spectacular. Silkworm boss is very cute. Three weeks later, his mouth was spinning, his feet were lying on my silk tray, and he kept shaking his head. He shook his head and vomited here for a while, and he was knitting there for a while. It is really interesting! It has wrapped itself up now, so no one can see it. Its cocoon is like an oval yellow pebble, covered with spots and some beautiful stripes, just like some braids!
Silkworm boss, you are really a naughty boy. You know I want to keep an observation diary, but you hide yourself. But I think this "mosquito net" you knitted is beautiful, so mosquitoes won't bite you again, right? Hee hee.
Silkworm observation diary 4 brought back some guests from school today. 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 there are nine little silkworms, which I 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.
