Silkworm rearing diary 400 words

I brought back some silkworm babies last week. They are black and black and white. They are very cute. In the evening, my father and I changed a piece of mulberry leaf together. First, we spread a piece of white paper on the table, then my father changed a piece of mulberry leaves left by the silkworm baby, and finally put the silkworm baby on it, covered it with a lid and tied it with a rubber band.

Three days have passed, and the black silkworm baby, which is less than one centimeter, has now become a white silkworm baby of more than one centimeter. This is my first time raising silkworms. When I brought them back, I put them in my hand and counted their legs. ...

I like sericulture!

Another week has passed, and the silkworm baby has grown up a lot, from black to white to yellow. I gave it a gentle press with my hand. White silkworm baby is hard, yellow silkworm baby is soft. As soon as I pressed it, it went soft. I held my head high as if to say, "Stop pressing it, it hurts!" " So as soon as I let go, the little silkworm ran away.

Mulberry leaves are fed too much now. I used to feed it twice a day, but now I have to feed it three times. I wish it could cocoon quickly!

Two weeks later, some silkworms have cocooned and there are four silkworms. They have cocoons of three colors: yellow, white and orange. Two of them are white, one is orange, the other is yellow, and the others have not yet cocooned. They are still eating, and some are looking for places to prepare for cocoon formation! I watch them grow up every day and feed them mulberry leaves.

I hope they will cocoon soon!

Silkworm rearing composition 400 words

I bought some silkworms yesterday and prepared to raise them. When I got home, I found a small box, the bottom of which was glued with transparent glue, and many holes were punched, and a piece of white paper was covered on it, and the "home" of the silkworm baby was ready! I carefully put the silkworm babies in their "home". They crawl around inside, some stick their heads out and keep swinging; Some crawl around on the paper at an extremely fast speed; Some people are dying and lying motionless on the ground ... I suddenly realized, how could I forget to feed mulberry leaves to silkworm babies? I quickly grabbed a handful of mulberry leaves and put them in the box. These little guys began to eat: some chewed from the corner to the middle, like digging a tunnel; Some dug a small hole in the middle and attacked the border region from the center; Others, whether they like it or not, pounce on the leaves as soon as they see them ... At noon, I saw that the silkworm baby was not moving and was resting. Their rest posture is really full of gestures: some are lying there motionless, as if they were fixed; Some are "feet hanging in the air" lying on their backs, as if they had a beautiful dream; Some people sleep on mulberry leaves, as if afraid that mulberry leaves will be taken away by others ... Ah, raising silkworm babies is so interesting! I want to take good care of silkworm babies, so that they can eat well, sleep well, grow strong and grow white and big (I hope it will help you, hope to adopt it! )

The observation diary is required to be more than 400 words (fourth grade level)

After Chinese class that day, the teacher asked us to go home and plant a plant and observe its growth process. As soon as I got home, I asked my grandmother for some soybeans and buried them carefully in the soil. My grandmother told me that it needs enough water to grow soybeans. After I planted the soybeans, I began to water them. A few days have passed and nothing has changed. A week later, I found that the soil where soybeans were planted was higher than other places. When I gently turned over the soil, it turned out that the soybean had a pale yellow bud. A few days after it was unearthed, the bud turned green again. Two days later, the light yellow one is small? Several leaves have grown in the garden, which are light green and very lovely. I want to see it every day. As the days passed, the buds grew taller and taller. I put some sticks in the soil, and the vines of soybeans climbed up along the sticks. Soon, they climbed to the top of the branch. After half a month, pods grew on the vines, and there was a thin layer of hair on the pods, which felt soft and interesting. The pods also gradually deepened from the light green at the beginning. Grandma told me this is my favorite edamame. I watched it grow up little by little, and my heart was full of joy. When the pods turn into Huang Shi, you can pick beans. I plucked the pods from the vine. Hey, this is a big gain. There are at least two soybeans in a pod. I always * * harvest 10 pods and more than 20 soybeans! Through this bean planting, I know that as long as I work hard, I will definitely get something.

Four-grade observation diary 400 words

Ducks are in the city, facing tall buildings and cars coming and going every day, and they feel bored after watching them for a long time. Every once in a while, I will go to my grandfather's house in the country to play. There are wide farmland, green rice, grazing cattle and sheep, and especially I feel very comfortable when I see the lively ducks in my grandfather's house. My grandfather's duck is very cute, with a round flat mouth and round eyes on both sides of my head. I always like to look around. Ducks like to wear clothes of various colors. The sun shines on them and they look beautiful. Duck's wings are a little big. When it is fanned, it is cooler than a fan. A pair of yellow feet support a fatter body and walk arrogantly. Ducks swim in the river every day. Sometimes they catch small fish and shrimp in the river. After swimming, they will go ashore and go back to my grandfather's yard, quacking. At this time, grandpa poured some corn from the house on the ground, and the ducks began to compete for corn. After eating, they lazily returned to their nests. Some ducks lay eggs in their nests. Grandpa always says "Ducks are really capable" when he sees ducks laying eggs. Grandpa's duck is still a good helper at home! Every time a guest comes, the ducks will gather around and quack, and when people leave, they will quack constantly, as if to say to the guests, "Go slowly, go slowly." Ducks often play with me. Sometimes they pull my pants with their mouths. Sometimes they flap their wings, twist their heavy bodies and dance for me. Every time I leave my grandfather's house, they follow me for dozens of steps, as if reluctant to part with me. I like my grandpa's lively and lovely ducks very much.

It is required to observe the diary of bug about 400 words.

A suit of black armor and two slender tentacles make up a brave little black creature-ant. Every time I walk in the golden campus, I will find a few small "!" Bypass my foot, that's an ant. It doesn't seem to realize the behemoth next to it, and it still walks slowly. The arrogant gait can't help but hurt my self-esteem, and the little ants dare to put on airs in front of me. There is no need to bleed, just poke it gently on its two "antennas" with a small wicker, and it will be scared to run around. At this time, I will be as excited as defeating a powerful enemy, but it is a small ant after all. Perhaps because of my naughty, I started a "war" with such a kind and weak ant, which is obviously unfair to it. But since I read an anecdote about ants, I can't help but admire this niche product. This anecdote is: What animal has the greatest strength in the world? The answer is ants, because ants can carry objects six times their own weight. Even if the weight is 100 times heavier than that of ants, it is just a little effort for people, but it is a great job for small ants. Little creature, little creature, I didn't expect your little body to contain so much power. Happy-go-lucky, vast fertile land is a comfortable home for ants. One by one, small creatures united to form a powerful ant family. Worker ants and queen ants do their best, but they don't "distribute according to work". Worker ants have worked hard for many years, serving the queen ants and feeding the young ants until they die of heart failure, while the queen ants dominate the world and live a pampered life. This is really unfair. I can't help complaining about the fate of worker ants. I really hope that one day the peaceful sunshine can shine into the dark ant nest. —— Diary of observation on silkworm growth. Today, the motionless ant silkworm didn't move at all, just swept it gently with its blade and rolled away. In fact, its body is already stiff, but I don't want to accept this fact. Today I officially declare it dead, but I will keep it in a silkworm box for a day and throw it away tomorrow. At the same time, I also announced that an ant silkworm was missing, because I couldn't find its trace. There is another one that is not good-looking, but this one, I prefer to understand as molting. The other four little silkworms are still moving, as if they are tireless. A lot of their droppings were left on the napkin. These feces are pure black, much smaller than sand. With a light blow, these small particles ran away without a trace. In order to observe, I often open the silkworm box and take a closer look with a magnifying glass. I wonder if they are afraid of this move, and to what extent? These days, the temperature is too low (for their lives), the surrounding sounds are noisy, and sometimes there are strong lights. I think these factors will affect their normal life. For them, they are stars now, and we are more like paparazzi in Hong Kong movies, constantly harassing and exploring their secrets. Today's three second-instar silkworms are 6 mm long and their heads are black and small, so it is not easy to observe more detailed features. The chest is bigger and longer than the head and abdomen, and three pairs of claws grow here. The abdomen has seven segments, the length is similar, and there are four pairs of abdomen feet longer than this. Which specific paragraphs remain to be further observed tomorrow. Now these young silkworms have been excreted, of course, they are eating, which can be judged from their leaves. But silkworm leaves are not as much as I expected, and there are few gaps in the leaves I have eaten. Maybe it's that silkworms have a small appetite and can't eat more mulberry leaves. I have been observing for 5 minutes, and three silkworms have been crawling from the back of mulberry leaves to the front, and then from the front to the back. Occasionally stay by the leaves, don't talk, just turn your head. Big silkworms eat for a living, but these little silkworms spend their main time playing and having fun. I think of cats, dogs and even children. Isn't it always like this? Does this property also exist in young silkworms? Silkworm's life is only a short month, and they use these short days to enjoy the happiness of childhood, which is what we are willing to accept. Spider Today, I caught an Okumo from the yard. It has eight slender legs with some fluff on them. Its head is white, its abdomen is golden yellow, and there are some brown patterns on it, which gives people a feeling of beauty and fear. I put it in a plastic box and prepared to feed it for a while. Because I like insects, and I prefer to raise insects, from which I can learn a lot that TV and books can't. I'm going to observe how spiders weave webs first. That night, I took a flashlight and began to observe carefully. I saw it hang a silk from the tail to form a straight line, and then it repeated this action from all angles to form a pentagonal frame. Then, it began to weave around the frame from the outside to the inside. A few hours later, it finally wove a big net. The most interesting thing is predation. I caught a small cockroach and put it in its net. The cockroach is trapped in the net. I saw that the spider, like a wild animal, wrapped the cockroach in a net with lightning speed, plunged two tusks into the cockroach, paralyzed it, and began to enjoy this delicious meal slowly. Something happened that made me depressed. The spider in the box is missing. Just when I was worried, I suddenly saw a slender spider silk, facing the ceiling. Looking up, it turned out that the spider had woven a bigger net on the ceiling of the balcony, and it was lying quietly on the net. A sudden gust of wind blew the cobwebs to pieces. It began to mend the net. I saw it hanging down the broken wall and climbing to another wall, and found that it had woven a shiny silk. After several rounds, it finally mended the net. Just as it was resting, another branch fell on the net, and the spider lost all its efforts. I thought it could never be repaired, and I was sure to find another place to knit another one. But I was wrong. It began to repair again, and after a few hours, it finally succeeded. I think we will give up when we finally get a little setback in life. Should we learn from spiders? Fruit this morning, I caught a fruit in the grass in front of my house. I carefully observed that its body is green, with a long beard and six feet. The first four feet are used for walking and the last two feet are used for jumping. Its mouth is transparent and consists of four parts. It has no teeth. When eating, grab it with one foot first, then grind it slowly with your mouth before eating. Fruit has a sharp tail and always likes to put its feet in its mouth. It also likes to climb high. If you put it on a fan to tease it, it will soon be panting and sweating, which will be very funny. It can also jump, jumping very high. Guo Guo sings by rubbing his wings, not with his mouth. He is a born singer. Guoguo also likes eating locusts. I put a locust in the cage of Guoguo. After a while, I want to take it out to play. When I saw it, the locusts had disappeared. Is it out? In order to verify, I caught another locust and put it in. This time, I clearly saw that locusts were slowly eaten by slugs. I only know that fruit likes to eat vegetables and grass, but I never thought that fruit also eats insects. It turns out that fruit is also a beneficial insect!

It takes 400 words to keep a diary (new observation).

Observation diary (Fan Wen) found an ant hole today, under the corner next to grandparents' house. I caught an ant, which is made up of three small sesame seeds. The head and belly are black, like two bulging sesame seeds, and the middle is yellowish brown, like a shriveled sesame seed. The ant's body is about 0.5 cm long, and it is as bright as a layer of paint. Ants have two tentacles on their heads, which often shake gently. The ant's mouth is like a little tiger pliers, which opens and closes one by one. Ant's legs are thin and long, and there are six in one. Its legs are brown like its body, so it runs fast because it is long. I put a small piece of meat next to the ant hole, and an ant found it. It touched the meat and went back. After a while, it came to touch the meat and went back, and so on several times. At this time, three ants came again, and they also came to eat meat. One of them went back to the cave. Soon, several ants lined up from the hole and went straight to the meat. Then there are more and more ants. An hour later, I came back to observe and found that the ants had transported the meat to the door of the cave, and the meat was covered with ants. I spilled water on the ant hole. There used to be a pile of fine soil in the cave, but now it is wet and scattered. Then I saw many ants coming out. They kept pushing the soil out of the hole, and soon the hole was opened, and ants could go in and out at will. Through this observation, I think ants are United, hardworking and fearless animals. Today, the immobile ant silkworm is still motionless. The leaves were swept gently, and it rolled out a long way. In fact, its body is already stiff, but I don't want to accept this fact. Today I officially declare it dead, but I will keep it in a silkworm box for a day and throw it away tomorrow. At the same time, I also announced that an ant silkworm was missing, because I couldn't find its trace. There is another one that is not good-looking, but this one, I prefer to understand as molting.
