Time flies like a horse, and a day has passed. I believe you must have a lot of experience to share. At this time, how can the most critical diary be left? What are the novel and rich contents in diary writing? The following is my diary of observing silkworms. Welcome everyone to learn from it, I hope it will help you.

The diary of observing silkworm 1 is over. A class 2 (3) student rushed into our classroom and said loudly, "Miss Wang is coming to send silkworms!" " "

Miss Wang came with a mysterious box in her hand. Open the box. There is a piece of paper in it. There are many small black spots on the paper. It looks like many small sesame seeds, but it is smaller than sesame seeds. It is round and flat, most of which are dark black and a few are gray.

Teacher Wang divided the paper with silkworm eggs on it into many pieces, and I also got a small piece. I shook the paper, but no eggs fell. I counted, wow! There are more than one hundred. I hope they all hatch. I must prepare a warm and comfortable home for the silkworm baby!

Yesterday morning, our classmates' silkworm baby boxes arrived at the station, and the classmates were ecstatic.

Yesterday, when I came home, my silkworm baby Huanhuan walked a tightrope on the mulberry leaf pole. It was as excellent as 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 has a bulging stomach, so she is called "Yuanyuan".

Today, I did an experiment. Can silkworms hear?

In the evening, I asked my father to turn on "Listen to everything". I opened the silkworm box and played "That Night" with a loud stereo. Two or three silkworm babies looked up as if to say, "What are we listening to?"

Can silkworms really hear? I played it again, but the silkworm looked up at me and listened curiously ... what an interesting thing!

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 very smooth!

It's great to observe the diary of silkworm change 3! You can raise silkworm babies!

The next day, my mother bought four little silkworms for me to raise. I observed that the baby silkworm has a big head but a small body. Its eyes are almost invisible, its nose is big, its mouth is in the middle of it, and there is some hair. Its body is long and cylindrical, and there are sixteen short and thin feet under it. If I put one in front of the young silkworms, they will climb over and enjoy it.

As time goes by, the silkworm baby grows up gradually. Once I went to see them, they didn't move or eat mulberry leaves. There is a dark thing behind them. I am very curious. My mother came up to me with mulberry leaves in her hand and said, "Don't think that silkworms are dead, they just shed their skins!" " I see. It really scared me.

A few weeks later, I went to see silkworms and found that they began to spin silk. They shook their heads and vomited round and round. The thicker they vomited, the worse they vomited. A few days later, they broke out of their cocoons and became moths.

Silkworm babies are so interesting and cute!

Observing the diary of Silkworm 4 on Friday morning, I don't want to get up. My mother said, "Silkworm babies are starving." I immediately opened my eyes, put on clothes and pants, and quickly ran to the place where the silkworm baby was put. I found that the silkworm baby has grown up a lot, and all the mulberry leaves put last night have been eaten up. I quickly took out new mulberry leaves and put them on. Soon, the silkworm babies began to enjoy them.

Silkworm babies sometimes rest, sometimes eat mulberry leaves, sometimes take a walk, and sometimes play hide-and-seek with me. They are hidden under mulberry leaves, but I can't find them. I'm anxious. They are picky eaters, eating only mulberry leaves and not eating anything else. If you give them a fresh mulberry leaf, they will soon be afraid of the past, and the old mulberry leaf will soon be abandoned.

I like my silkworm baby very much.

Observation of Silkworm Diary April 5 18

Today, I bought five silkworms from the stall at the door, and I observed them.

These silkworms have six black stripes. It is about 1 cm long and has twelve small feet. The whole body is yellow and white, and the walking skills are not very good. If you don't look carefully, you will think they are crawling! Because they belong to the larval stage, the speed of eating mulberry leaves is very slow, and they are not finished in an hour or so.

May 5

Now, they have grown up a lot. The body changed from yellow-white to pure white, and the length increased from 1 cm to 3 cm. And I found that a silkworm has a cocoon, and the cocoon is still golden yellow, which makes me ecstatic.

May 20(th)

Today, they all break out of their cocoons and become silkworm moths. Silkworm moths are white and have gray wings, but they can't fly. In addition, they began to lay eggs. Their eggs are yellow, sesame-sized, and a little sunken in the middle.

Silkworm rearing is really interesting and fun!

I am naturally afraid of fleshy insects, so I always stay away from silkworms. But my good friend Jie Chen keeps 12 silkworms. Under her influence, I gradually became interested in those squirming niche products.

Silkworms are black when they are born, and they lie on pieces of mulberry leaves like black grains of rice. We cut the mulberry leaves into thin slices and feed them. There should be no water on the mulberry leaves, otherwise the silkworms will have a stomachache. Silkworms grow very fast and shed their skin every few days. Slowly, the silkworms get fatter and whiter as they eat. When you are quiet, you will hear "rustling, rustling" silkworms eating mulberry leaves. Hearing this voice, I felt a little joy in my heart. I seem to watch silkworms grow up little by little.

Silkworms begin to cocoon after shedding their skins four times. It dragged the fat white body to the haystack we prepared for it, shook its head and began to spin silk. The crystal silk vomited more and more, and gradually surrounded it. Soon after, a moth came out of the cocoon and flapped its wings and flew away. I looked at all this in surprise, surprised at the strangeness of life.

I never knew silkworms were so cute and their life span was so short!

It will be sunny on Monday, April 6th.

So far, the silkworm's body is getting thicker and bigger, bigger than the earthworm, and the silkworm has grown a lot. Moreover, I also found that the concave part of each section of the silkworm turned silver gray, while the convex part became whiter and whiter!

It will be cloudy on Tuesday, April 7th.

Today, I have a deeper understanding of the living habits of silkworms. For example, when eating mulberry leaves, silkworms like to bite out a semicircle first and then eat it slowly. Moreover, the food intake of silkworms has increased significantly recently, and silkworms spin silk. Silkworms stick silk to leaves first, and then slowly stretch it. These silks are so flexible that they can hang silkworms directly for a day! In addition, I also found that silkworms don't like to live in groups, but prefer to live alone.

It turned cloudy on Thursday, April 9.

In fact, the silkworm body is also very interesting. For example, silkworms can easily crawl on the edge of leaves. It turns out that silkworms have a lot of fine hairs on their feet. There is also a conical horn in the abdomen of silkworm. According to the teacher, the straighter it is, the healthier its surface is. It will straighten after I bend it! And the silkworm's mouth can shrink at will! Finally, I found that the silkworm's body didn't move much, but its head moved the most.

I have two little silkworms, only one millimeter in size, and very thin in shape, like refills. They have just been born, so they are very thin and small.

They all eat mulberry leaves. I put a piece of mulberry leaf for the young silkworm to eat. It took three days to finish eating because the silkworm baby eats a small amount of food. Under my careful cultivation, they grew up slowly. Every time they eat mulberry leaves, their tails will swing and rustle. When they are full, the silkworms raise their heads and start to sleep. After waking up, they continued to eat Sasha Vujacic. In this way, after a few months, the silkworms grew sturdily and slowly, all fat and their feet became transparent.

Silkworm babies are beginning to cocoon. It spun silk from side to side and slowly wrapped itself in a cocoon. At first, the cocoon was soft and gradually hardened. Later, a winged moth came out of the cocoon, and the moth began to lay eggs and reproduce.

Silkworm baby's It's a Wonderful Life!

In ancient times, China's silk was priceless, and even western gold could not compare with it. The famous "Silk Road" was China's earliest trade route to foreign countries. I learned a lesson about sericulture in science class these days, so I bought some silkworms after school and began to observe their hatching.

These silkworms are white and fat, and there are many small "soft thorns" on the back of their buttocks. Their small mouths are like small black beans, their feet are like "flower cores" and their whole bodies are covered with white "armor".

Silkworm babies are cute to move. Qi Xin twisted his feet together, contracted forward as if he felt cold, and then slowly stretched forward. It walks very slowly, even slower than the tortoise. It always eats mulberry leaves slowly, and it is always picky about food-when it is eating one mulberry leaf, it will eat another young leaf. It tastes as delicate as a lady. If it doesn't look good, it really won't come out. But after a long time, a thick layer of leaves will be scattered.

Looking at these little silkworms, I remembered a poem: silkworms in spring will spin silk until they die. Although they are very young, their spirit is touching.

I brought some powerful silkworms to Wu Yuanyang's house to show him. Last week, he said that his silkworm was four times as big as mine.

As soon as I arrived at Wu Yuanyang's house, he knew why I had come. He took a box and there was nothing in it. I smiled: "Here it is!" ! He skillfully opened the lid of the box and three silkworms appeared in front of my eyes. I saw a half-cocoon silkworm. "How so small!" I said in a sarcastic tone.

"The smallest medium-sized one has no cocoon. "He picked up another box, and a mutant silkworm caught my attention. "What is this silkworm? How many mulberry leaves do you feed it a day? " This "mutant silkworm" is about eight centimeters. It is an expert in eating food. I suspect that Wu Yuanyang made his silkworm beef grow so fat. This medium-sized silkworm covers two large mulberry leaves at once, and its mouth is wide open, which seems to eat a small mulberry leaf at once. It saw a big mulberry leaf and ran over. It immediately took a few bites with its mouth and found a soft place to eat.

This is my friend's silkworm.

Observing the Silkworm Diary 1 1 A few days ago, my family raised a big white silkworm baby. Now, my silkworm baby has become a pupa. This time is very interesting!

At first, my silkworm baby shed its skin twice. Very cute. I put it in a small box and put some mulberry leaves. It regularly eats mulberry leaves from top to bottom. A few days later, my silkworm baby molted once. This time, its skin seems to be much bigger than before.

Let me take a closer look, hey!

My baby silkworm seems to have many small eyes. Oh, so this is called compound eye. Compound eyes are made up of many small eyes. In this way, a few days later, my silkworm baby shed its skin again, but this time it was different. My silkworm baby began to turn yellow without eating mulberry leaves. I asked my father that it was to spin silk! Many of our quilts are made of it. Sure enough, my silkworm baby began to spin silk. Slowly, my silkworm baby turned into a cocoon. Oh, how nice!

Silkworm Observation Diary 12 20xx April 18 Friday Fine Today, I bought five silkworms at the stall at the door, and I observed them.

Saturday, May 20th, 20xx is fine. Today, they all break out of their cocoons and become silkworm moths. Silkworm moths are white and have gray wings, but they can't fly. In addition, they began to lay eggs. Their eggs are yellow, sesame-sized, and a little sunken in the middle.

Silkworm rearing is really interesting and fun!

Observe the Silkworm Diary 13 In April, the silkworm eggs in my schoolbag will hatch. Silkworm is very strange. I thought they should be white when they just hatched, but what I saw was black, only the size of sesame seeds. I observed it carefully with a magnifying glass and found that the silkworm's body was covered with fluff, uneven in color and black and white.

At first, I couldn't find mulberry leaves. Later, the science teacher told us that silkworms should also eat raw vegetable leaves. So I asked my mother to go to the market to buy lettuce. I immediately picked lettuce leaves for young silkworms to eat, but they didn't seem to like them very much, so I decided to look for mulberry trees. After "hardships", I finally found a mulberry tree in a nearby community. Now my silkworm eats the mulberry leaves I picked every day and grows vigorously. They have been "born" for nearly a month now, and the largest silkworm is 2.3 cm long.

I hope they will grow up quickly, become silkworm moths and lay a lot of eggs.

Silkworm observation diary 14 Silkworm is the main raw material source of LEPIDOPTERA insects and silk, which plays an important role in human economic life and cultural history. The following is a 200-word silkworm observation diary. I hope you like it. The observation diary of silkworm is 200 words each.

This morning, my father and I went to grandma's house to see silkworms. At first glance, the silkworm that used to be like a short thin thread has grown white and fat, as thick as my finger. One silkworm is cocooned and the other three are spinning silk. I watched with interest. Looking at these silkworms spinning cocoons, I suddenly understood the meaning of the idiom "make a cocoon and bind yourself". At this time, grandma came out of the house and said that the silkworm was full of treasures. It ate worthless mulberry leaves, but spit out gorgeous silk thread. Even the excrement it pulls out has a nice name-silkworm excrement. You can make a pillow and sleep with it, which has the health care function of improving eyesight and lowering blood pressure! After hearing this, I like my silkworm even more.

Next year, I will raise more silkworms.
