A 200-word essay on raising silkworm babies

A few days ago, the science teacher sent us silkworm babies for us to raise.

I happily brought the silkworm workshop home, opened it and saw 6 silkworms eating feed. Next to it were a magnifying glass, a pair of tweezers, two feed sticks, and an instruction manual. Silkworm babies are so cute. They crawl around on the feed, shrinking and stretching.

It’s May Day holiday, so I have time to raise them. When I see that the silkworm babies' house is dirty, I clean their room and add feed to them if there is no feed. I found that they will change color after eating feed. They will turn light red when eating red feed, and light green when eating green feed. It is really strange.

I love my silkworm babies, I want to raise them fat and beautiful.

On the day of the Mid-Autumn Festival, our family went back to our hometown to celebrate the festival. I saw that the little silkworms raised by my third uncle were white and fat, about one centimeter long and very cute, so I came up with the idea of ??raising little silkworms. When we returned to the city, we had a box of silkworms and a bag of mulberry leaves in our hands.

After returning home, my father and I began to look for a suitable house for the baby. The shoe box was too small and the milk box was too deep. Finally, we found a mooncake box, which had just the right space and size.

As soon as the "housing" problem was solved, the food problem came again. Because the mulberry leaves are dry and large, they are too cold just after being taken out of the refrigerator, and the little silkworms cannot eat them at all. We had no choice but to take the mulberry leaves out of the refrigerator in advance, cut them into strips, and soak them in water in advance. Only then did the silkworms open their "golden mouths" and eat them with "big mouthfuls".

At night, I moved the silkworm babies to a warm bedroom and fell into a sweet dream with them. The next morning, I opened the lid of the box to visit the silkworms. I found that all the silkworms had grown up a little, some were 0.5 centimeters longer, and some were two or three millimeters longer. I saw that the mulberry leaf had become The contents of the silkworms' bellies had been eaten up, leaving only a few leaf veins. The silkworms were raising their heads, as if they were asking me for food. I quickly washed and dried the mulberry leaves, and evenly covered the silkworms' bodies. After a while, a subtle rustling sound came, and the silkworms were eating to their heart's content. First, he bites a small hole in the mulberry leaf, and then eats the mulberry leaves in circles around the hole, just like an excavator working continuously. I now finally understand what “cannibalization” really means.

A few days later, the silkworm babies’ bodies had grown a lot, but their food intake was less than before. I had an unknown feeling in my heart, so I quickly called my third uncle to ask them. Entered the "sleep" stage. They hold their heads high one by one and stay in a fixed place quietly, like a group of sculptures. There are two pairs of black ball-shaped patterns on the back, which is very cute.

After about a day and night, the silkworm babies "awoke" one after another. Their original coats could no longer accommodate their growing trunks, so the silkworm babies began to molt. As the body squirmed, the skin fell off after a while. At this time, the bodies of the silkworm babies looked thicker, and their length also increased by a few millimeters.

In recent days, the silkworm babies’ food intake has increased sharply, and the mother has no choice but to go to the wild to collect wild mulberry leaves for them to eat. After this feast, they ushered in the final stage of "life" - cocooning themselves.

My mother and I cut the cardboard into strips, cut the openings evenly, inserted them into each other, and made a "lattice cluster" for them, and then carefully moved them to the "lattice cluster" "At this time, the fat silkworm babies became thinner and smaller, and their bodies became golden and transparent. The silkworm babies each chose a "feng shui treasure land" and started making cocoons without stopping. The lower part of their bodies does not move, their heads swing back and forth, and the silk is pulled from here to there, and from there to here. With just a few "strokes", the general outline of the cocoon is "outlined", followed by the encryption work. . After a long time, the silkworm cocoon has completely covered the silkworm knot, but through the silkworm cocoon, you can still see a black shadow swaying around. At this time, people can't help but feel a tragic and heartbreaking feeling.

"The spring silkworm will not run out of silk until it dies, and the wax torch will turn to ashes before the tears dry up." Silkworms end their lives by "making a cocoon and binding themselves", how magnificent! How great! .

A 600-word essay on raising silkworms

Today I can raise silkworms myself! I'm so excited that I don't know how to describe it! The science teacher said that they should be given fresh and tender mulberry leaves to eat every day, which should be washed and dried. This is really a difficult task!

I was really scared when I came into contact with the babies for the first time, thinking that these soft molluscs would bite me unexpectedly. When I get home from school every day, the first thing I do is to feed the babies one by one, and I also have to clean their house. I work really hard to ensure that the babies have food to eat. One day, because I was worried that the babies would not have enough mulberry leaves to eat, I went around the school asking people for mulberry leaves, but none of my classmates were willing to give them to me, so I had to go home dejected. I looked at the hungry look of the babies. I was so sad that I couldn't help but shed tears. I kept mumbling: Will the babies die? So how do I explain it to the science teacher? Just when I was frowning, my father came back with two packs of mulberry leaves in his hand. I was so excited, ah! The babies are finally saved! I couldn't wait to wash the two packages of mulberry leaves, and then took them directly to the sun to dry them, eager to feed them to the babies. The babies twisted their bodies and ate the mulberry leaves with gusto, and made the sound of "sand-sand-" from time to time, just like the song sung by Miss Chunyu. I'm so happy that the babies escaped this.

From the whole process of raising silkworms, I finally understood the original meaning of the word "cocooning oneself". Time flies. Under my careful care, the babies spit out snow-white filaments and made thick cocoons. They gradually turned into moths inside, and finally broke out of the cocoons, leaving countless children behind. Countless future generations, let them continue to benefit mankind. This reminds me of the reason why the eternally famous saying written by the poet Li Shangyin is so touching: "The spring silkworms will die when the silkworms die, and the wax torches will turn to ashes before the tears dry up."

The experience of raising silkworms not only taught me a lot of scientific knowledge, but also made me understand a profound truth: the value of a person lies in dedicating his or her life.

After the beginning of spring this year, my grandma raised half a silkworm baby.

On May 1st, Labor Day, grandma went to get half a sheet of silkworm seeds. When I was waiting for my grandma to bring half a sheet of silkworm seeds home, I went to greet her before she came in. I took the silkworm seeds from grandma's hand and ran to the silkworm room.

When I came to the silkworm room, I couldn’t wait to put the silkworm seeds on a plaque and spread out the paper. At this time, I saw that there were many small black spots there, and a few very thin silkworms had hatched out of the eggs. It is crawling slowly on the paper. Grandma walked in quickly. She was not at all as slow as usual. She took the paper from my hand and put it on a stove.

The next day, all those little silkworm babies hatched out. They squirmed on the paper. Grandma put some mulberry leaves cut into the size of rice grains on the little silkworms. Those silkworms were quickly eaten. I found it very interesting and grabbed a handful of finely chopped mulberry leaves and sprinkled them on the little silkworms. Grandma said: "Okay, don't scatter the leaves. Don't let them eat too much. Otherwise, they will eat bad." I stopped scattering the leaves.

Now they have slept three times. These silkworms have grown up, but they are still far from going up the mountain!

One day later, I saw my grandma feeding mulberry leaves to the silkworm babies. I wanted to tell grandma that I would help you feed them. However, I saw that the silkworms were very big. Some looked like caterpillars, and I felt a little scared, so I said to my grandma: "I don't dare to feed such big silkworms." Grandma said: "It's really useless, even these silkworms are scared!" What was I thinking? Silkworm baby, it’s obviously a caterpillar.

I looked carefully and found that the body of the silkworm was similar to that of a caterpillar, and it was also white in color. There was a small black thorn on the top of the tail, and eight small legs on the bottom of the body. There is a small black-gray circle under the head. There are threads on the back of the silkworm. I carefully counted a few silkworms and found that most of them had seven segments. Their sleeping posture is also different from ours. Instead of lying on a bed, they sleep with their chest raised and their head raised.

I was very surprised and curious to see these silkworm babies sleeping. They only eat mulberry leaves and nothing else. I think these silkworms are really picky eaters. When I grow up, I will change their eating habits so that they can eat anything.
