Observe earthworm diary

It's almost over. There must be a lot of feelings in my heart. Please write them down in my diary. But how can I keep a diary to shine? The following is my diary of observing earthworms, hoping to help everyone.

Observe the earthworm diary 1 This morning, in order to complete the task assigned by the science teacher, we were planting onions. Because there was no soil, my father and I went to the flower beds in the community to get some soil.

Suddenly, I found a red earthworm crawling around in the soil, so I quickly picked it up, but the earthworm struggled in my hand and scared me, but I finally caught its ring and put it in the onion-growing soil. I found this earthworm digging a hole in the soil with its mouth, and soon it disappeared into the soil.

At this time, I dug up the soil again, but the red earthworm couldn't wait to get into the soil again, and it was very fast. I dug the soil again. Unexpectedly, this time the earthworm gave me an acrobatic performance. It slowly raised its tail like a small flagpole, and immediately got into the soil after this action. I dug up the dirt again. This little guy and I played a "game"-hide and seek. First, he held his head high, and then hurriedly hid in the dirt. As if to say, "wait a minute, come back to me when I hide."

Afraid of hurting it, I carefully fiddled with the soil with my hands and finally pulled it back with great effort. Earthworms at the moment are really like a little friend who is playing hide-and-seek with me! Through this careful observation, I know that earthworms dig holes with their mouths, and it is not easy to dig out the soil with their soft mouths!

Observe the earthworm diary. It's cloudy and sunny on Sunday, May 9th.

Yesterday morning, Wang dug the soil with a small shovel picked up from outside. According to him, he dug a hole beside the bush to look for earthworms. I said, "How can there be earthworms now? It's so hot! " But he is still digging for earthworms buried in the soil.

I won't stop him. After a few minutes, he said in surprise, "Look, there are earthworms here!" " "When I heard this, I didn't care about my own business, so I quickly leaned down and asked," Earthworms! ? Where is it? Come on, show me! "

He pointed this out to me. I saw earthworms crawling in Wang's shovel, and there was some dirt in it. He put the earthworm on the ground and let us observe it together. Earthworms are crawling to places with dirt, probably to eat dirt! However, instead of eating dirt, he climbed onto the grass. As soon as I saw it, I quickly took out a branch to block its way. The earthworm saw it, thought I was teasing it, and "danced" wildly. I was shocked and left the branch in horror. I said to the king, "Look, isn't this scary?" "Wow, yes, it's scary!" After that, he turned to dig earthworms.

"You see, there is an earthworm next to the soil on the right! As I expected, there is an earthworm hidden in the soil. It keeps moving, as if it were going to fall.

Look, this is my record of observing earthworms!

Observe the earthworm diary 3 20xx10 June 14 Sunday sunny.

I am a little earthworm, named Honghong, and I live happily with my friends. I like dark and humid places. As long as there is light coming at me, I will immediately hide in the nearby soil. Our earthworm family suffers from acrophobia. Sometimes my master plays with me and picks me up with a small stick. I dare not move for fear of falling. My greatest pleasure is to drill around in the soil, play hide-and-seek with my friends and loosen the soil for my dear Mr. Tu. As long as I have the conditions, I also like to go out to play with my friends, which is also a kind of fun. We also hold a group to keep warm. At this time, you will ask me, where is your home? Hey, hey, to tell you the truth, I have no home. Living in the soil is enough, and I don't have to dig any caves.

This is my life. I enjoy life very much. Oh, well, I don't have time to talk to you. I want to play with my partner.

I like many insects. Today I will introduce you to an insect. Its name is earthworm.

Earthworms like temperature, humidity, quietness, light, salt and tannin. Living in moist and well-ventilated soil during the day, the habitat depth is generally 10-20 cm, and coming out for food at night.

It feeds on rotten leaves, dried leaves, vegetable residues, crop straws, livestock manure, melon and fruit skins, waste residue from paper mills, breweries or flour mills, and domestic garbage in residential areas. I especially like sweet food, such as rotten apples, and I also like sour materials, but I don't like bitter materials and tannic materials. Salt has a toxic effect on it. Earthworms are animals with poor aerobic capacity. It is very sensitive to its surroundings. Suitable for loose soil with 15-25 degrees, humidity of 60%-70% and ph value of 6.5-7.5. If the conditions are wrong, it will climb out and escape.

Anyway, after listening to my introduction, you also like earthworm. In fact, many insects don't bite. You might as well go home and raise a few earthworms and observe. Maybe you will find more habits.

At school, the science teacher said that cutting an earthworm in half would turn into two earthworms. I want to do this experiment.

In the evening, my father and I catch earthworms in the flower beds of the community. After a while, we found a long earthworm. We picked up the earthworm with chopsticks and were about to put it in the paper cup when the flexible earthworm suddenly ran away. We have no choice but to wait patiently for the earthworm to appear again. At this moment, I had a brainwave and ran home to get a shovel. I shoveled a lot of soil directly into the paper cup with a shovel, and several earthworms came out at once, which startled us.

We can finally do the experiment. I first put a skipping earthworm into another paper cup, then cut it with a knife and pencil, and the earthworm twisted into two parts. Sure enough, as the teacher said, two earthworms can still survive. And my knife and pencil are stained with red blood. I didn't expect earthworms to bleed. The next day, I went to observe earthworms again. Sure enough, there are two earthworms crawling in the paper cup. It seems that they are not earthworms injured last night. Their wounds disappeared and the band grew. Earthworms have great vitality!

Earthworms are really a magical and interesting animal!

I came here after school yesterday afternoon-my uncle's home in the country. I was worried before going to bed last night and didn't know what to write.

At noon today, I found an earthworm in the ditch in front of my uncle's house. I thought to myself: Let's observe the earthworm. Earthworms look like what I saw on TV. His body is as long as chopsticks and the color is reddish brown. His round body is as thick as my little finger. When I found it, it was twisting from side to side, crawling forward, crawling and crawling, and getting into the soil. I quickly pulled it out of the soil, played with it for a while, and found that it would eat dirt and poop with it.

After lunch, I went to see the earthworm again and found a shriveled body. Why do earthworms die? Later, I looked it up and found out that earthworms like wet places. In the morning, the sun is very hot, drying the ground, and the water in the earthworm will be lost, so it dies.

Today, I saw a man digging earthworms, saying they were used for fishing. He also said: "If an earthworm is broken in half, the one without a head can regenerate its head and the one without a tail can regenerate its tail." I listened with a grain of salt.

Is the regeneration ability of earthworms really that strong? I decided to verify the truth of this sentence. I dug an earthworm as thick as wool. I put it on the plate and saw it squirming, arching forward for a while and shrinking back for a while.

I first prepared two plastic bottles, punched a lot of air holes in them, and then put some wet soil in them. Finally, I cut the earthworm with a knife, and its two bodies were struggling desperately. I put two earthworms in two plastic bottles and some wet soil. I'm waiting for a miracle.

The next day is the time for me to test the results. I really hope the experiment will succeed, but I'm a little worried. I carefully poured out the soil from two plastic bottles.

Ah! I saw two parts of the earthworm crawling, and they were both alive. Those without heads have heads and those without tails have tails. Earthworms have such tenacious vitality in their small bodies!

I saw the earthworm when I was reading a science book, and I observed it during my holiday!

One day, I caught an earthworm and put it in a bottle with sand. I don't think I can move, so I want to go out to play. As soon as I took a step, it crawled in the direction of the bottle mouth and I watched it. It crawled for a while and then fell down, and crawled and fell down again. It climbed many times in a row, but it didn't climb up, and it tired itself to death. After a while, I found a black thing in it, so I poured it out of the bottle. It rolled on the ground and its slender body twisted. I broke it with pebbles. It looks like feces and dirt. I don't know what that is. However, I made two pieces of earthworm and turned it over on the ground, as if nothing had happened. The book says this is the regeneration function of earthworms, which is really amazing!

I learned some knowledge about earthworms during this observation. The most important thing is that earthworms have the function of regeneration!

Observe the earthworm diary. It will be fine on Wednesday, September 3 1 Sunday.

There are many earthworms in our family, which are used for fishing.

Earthworms raised at home are different from those raised in the field. The earthworms in the field are black, long and thick, while our earthworms are red, not as thick as the earthworms in the field. It is lovely for fish in the river to eat earthworms raised in our family.

Listen to my father: "Earthworms have strong vitality and regeneration function."

I want to have a try.

So, I took out some chopsticks from my earthworm box to do the experiment. I took a knife and cut the earthworm in half. Earthworms immediately jumped up on the ground and struggled painfully. As soon as I saw it, I called my father and asked, "Dad, is the earthworm going to die?"

Dad said, "Never mind, it will be all right soon. You put him in the wet soil quickly. "

I quickly put it in the wet soil prepared in advance.

Two hours later, I went to see the earthworm that I cut in half with a knife. Thinking in my heart: will he die?

However, when I opened the soil, ah! My earthworms are not dead, they are crawling happily in the soil! Really, as my father said, earthworms have strong vitality and have the function of regeneration like gecko tails.

Observe the earthworm diary 10 It was a Sunday morning. I dug four earthworms from the vegetable garden and took them home. I cut off two of the front 15-20 sections, and the other two cut off the tail (about one tenth of the whole body length). I put these four cut earthworms in the soil of the flowerpot. The soil kept moist. In order to prevent the flowerpot from accumulating water, I made several holes in the bottom of the pot and put the flowerpot in a dark place.

After a week, I went to observe them. Gently push away the soil, earthworms exposed, but found no big changes, only to see that their wounds have healed. I covered them with dirt and put them back.

Another week later, I went to observe them again. When I looked at the soil, I found that earthworms had grown a lot. I decided to keep watching, cover them with wet soil and put them back.

Another week has passed. On this day, I went to observe them as soon as I got up. A miracle happened. When I gently parted the soil, four complete earthworms appeared in front of me, which made me blindsided. I cried excitedly, "Earthworms really have long tails! Earthworms are reborn! "

Observe the earthworm diary 1 1 Today, Miss Wang gave a worm to a group of four, and the classroom suddenly exploded.

After careful observation, we found that earthworm seems to have no eyes and mouth. Its body is as long as a match, and there is an endless belt on its brown-red fur. The head is near the girdle and the tail is far from the girdle. Turn it over and you will see a black line. This is its stomach.

Earthworms have no feet, but they crawl very fast, and their bodies stretch freely, as if they were dancing in a stretching dance. I hold it in my hand, and it has a long gold thread when it wriggles. I thought it was its urine. I asked the teacher, and the teacher said it was the trace left by its abdomen when it wriggled.

Teacher Wang asked us to do an experiment: cut the earthworm in half to see if it has the ability to regenerate. I suddenly have a thousand-pound stone in my hand. Chen and I summoned up our courage, picked up a ruler and chopped hard. It is divided into two halves. This part is struggling separately, as if to say: ah! It hurts! You executioners! Teacher Wang said: In less than three days, a tail will grow on the head, and the tail part will grow. After that, Miss Wang picked up the cup and showed us her earthworm. I was stunned. There is a drop of red blood on the cup.

Earthworms are really a strange animal.

Observe earthworm diary 12 It has been raining these days. Thank goodness, the sun finally came out. At this time, I was taking a leisurely walk on the grass. Habitually, I kicked off a big stone. Hey, what's this? When I looked carefully, it turned out to be worms. I carefully put one of the earthworms into the biscuit box and put a lot of soil.

I observed that the earthworm's body is soft, long and round, composed of many nodes, and its surface is rich in mucus. In order to know more about the life habits of earthworms, I did the following experiments:

I put a pile of dry soil, a pile of wet soil, a pile of fine sand and a pile of salt around the earthworm. Earthworms slowly want to move the wet soil. Earthworms seem to like wet environment.

I put a box across the table so that earthworms can climb in at any time. I shone a flashlight on the earthworm and it moved into the box at once.

Through these two experiments, it can be proved that earthworms are visual and like dark and humid environment.

I gently rolled the earthworm in the dry soil powder, and its skin began to become dry and twitch. I moistened the earthworm's skin with water, the spasm disappeared and the earthworm returned to normal. Later, I read in a science book that earthworms used to breathe through their skin.

The science book also says: "Earthworms are a useful animal. He can dig caves, which can loosen the soil, so the air can reach the roots of plants more easily. These caves are also conducive to drainage. "

Observing earthworm diary 13 In science class, we can observe many creatures, such as earthworms, snails, goldfish and so on. Then let's talk about earthworms!

In class, the teacher explained to us that earthworms are annelids. It likes to live in wet and soft soil and help farmers loosen the soil. Then the teacher took out a small earthworm, which looked like a thin long rope. It is motionless on the table and its body is very smooth. Why can it be soft in hard soil? Maybe it noticed that there was no danger and began to move slowly. When we provoked it with something, it actually bounced, like an excellent high jumper, and the originally calm atmosphere suddenly became active. I don't know what the earthworm ate with such good jumping ability. This increased our curiosity. Hearing the teacher say that the earthworm still has strong vitality and can be regenerated, we can't wait to cut the earthworm in half. Strange! How can there be no blood? Cut off two halves, and it can continue to crawl, so what is it breathing?

A little earthworm is amazing! I am more and more interested in earthworms. I must study this treasure house of knowledge and answer unanswered questions better.

Observe Earthworm Diary14 20xx It turned cloudy and sunny on Sunday, May 9th.

Yesterday morning, Wang dug the soil with a small shovel picked up from outside. According to him, he dug a hole beside the bush to look for earthworms. I said, "How can there be earthworms now?

Its body is as long as chopsticks, its color is reddish brown, and its round body is as thick as my little finger. When I found it, it twisted left and right, crawled forward with difficulty and climbed into the soil. I quickly dug it out of the soil.

After lunch, I went to see the earthworm again and found a shriveled body. Why do earthworms die? Later, I looked it up and found out that earthworms like wet places. In the morning, the sun was very hot. When the ground was dried, the water in the earthworm would be lost, so it died.
