Observe snail's fourth grade composition

In the daily study, work or life, many people have had the experience of writing, and they are all familiar with writing. By writing, we can gather scattered thoughts together. How to write a thoughtful and literary composition? The following is my composition about observing snails in grade four, for reference only. Welcome to reading.

When the weather was wet, I came across a snail. I want to leave it and let me solve all its secrets.

Thinking of this, I ran into the house without hesitation, took a magnifying glass and began to observe. I watched carefully with a magnifying glass and looked at it from different angles. I found that snails have two pairs of antennae, one is long and the other is short. I personally touched his long antenna again, and it shrank back at once. I think this snail is a little timid.

I looked at its short tentacles again and found that they were blinking. I guess it may be snail's eyes. In order to confirm the answer, I asked my mother again, and her mother said, "Yes, you guessed right!" " "

Later, I became interested in the snail's house and observed it. In order not to hurt this snail, I caught a few more as an experiment. I gently pinch their house, alas! It's all broken. It seems that the snail's house is not very strong.

In order to know more about snails, I continued to observe, and this time I observed more carefully. After my observation, I have come to a new conclusion: the snail's shell is sealed, and it will not die of thirst after living in it for three to five years. This is why snails like to stay in wet places.

Through this observation, I also know that being good at observation is a good habit, which can help us explore many mysteries of nature.

Observing Snails Composition 2, Grade 4 Today I observed snails. In my opinion, my heart has long wanted to know how snails breathe. What do snails eat? Snails have no feet. Why can it climb? So I have to take a good look.

First, I want to know what snails eat. I put the snail in a bottle, and then put some mosquitoes, some bread crumbs and some vegetable leaves in the bottle. At this time, the snail slowly crawled to the vegetable leaf, and then the snail began to eat the vegetable leaf. I understand that snails like to eat vegetable leaves. The second problem is that snails have no feet. Why can it crawl? I put the snail in a transparent cup and observed it carefully. It turns out that snails crawl with their stomachs and feet. The next question is how do snails breathe? I went to ask my father, and my father said, "A snail has a mouth, and it breathes through that mouth." I found a mouth on it. It used to breathe. After a while, I found the snail asleep. I want to wake it, but I don't know how to wake it. I asked my father again. My father said, "You put it in the water." I put the snail in the water, and the snail woke up slowly and climbed out of the water.

Snails are really interesting. I like watching snails!

Observing Snails Grade 4 Composition 3 There are two snails in my family. A shell is big and heavy, and the pattern on the shell is bit by bit. I named it "Congcong"; There is also a smaller shell, and the patterns on the shell are one by one. I named it Mingming.

Snails have long tentacles. I measured them, and they are 3 cm long. The "black gem" at the top of the antenna is its eye. There are two small tentacles under the tentacles, and under the small tentacles is a snail's mouth that can't be smaller. I looked at it with a magnifying glass and only saw a crack. I said to my mother, "This mouth might as well be called a crack." Snails' bellies are used for crawling. Its abdomen has many small feet, which are called "abdominal feet". Snails use these abdominal feet to crawl in waves. It also has an organ that secretes mucus in its abdomen, so the snail will leave mucus where it climbs.

Once, while cleaning the snail house, my mother wrote "Congcong" and "Mingming" on a napkin. After a while, I was surprised to find that "Congcong" and "Mingming" actually fought! Congcong went to Mingming, but Mingming couldn't get rid of Congcong after several struggles. Finally, her mother separated them.

Observing snails not only taught me a lot of scientific knowledge, but also brought me into close contact with small animals.

Today, I went to play outside. I found a small snail in a dark and humid place in the wild, so I became interested and took it home.

I put the snail in a light yellow box, and also put some green leaves and vegetables. As soon as it saw the delicious food, it ran over at once. After all, it was slow, so I ran for a whole 1 minute. I suddenly found white lines everywhere where it ran, which should be snail-eating mucus. Later, I got scientific confirmation. I accidentally bumped into it when I finished it. It seemed to feel attacked and shrank into its "small house" in the blink of an eye. I can't knock it out. It seems to be consumed with me.

I waited 1 minute, and then it poked its head out carefully and continued to watch quietly.

Look at this. I found that snails have no feet and walk with their bellies. I also found that snails have a toothed tongue, which is how snails eat. I brought a magnifying glass and carefully scanned the snail's whole body. It is found that the snail has two small eyes on its tentacles. Those eyes are so small that you can't find them without careful observation.

Snails are full of treasures, and they really like them more and more.

It rained the other day, and I was bored, so I played in the garden downstairs with my mother. Suddenly, I noticed many snails taking a leisurely walk in the morning!

I was curious, so I caught a few and observed them carefully. A snail's shell is its house. Its shell is spiral, with flowers and black, which is different from others. All the snails I caught were right-handed, and none of them were left-handed. Snails have two pairs of antennae, one long and the other short. It has a pair of small wind eyes on its long tentacles. I can't find its mouth. Strange, does it have no mouth? That's how you eat! Finally, I found a thin line under its short tentacles, and that is its mouth. I also found that the snail would leave some white liquid where it crawled. What is this? I looked up relevant information on the internet. It turns out that the mucus at the bottom of the snail can make the bottom of the snail wetter to avoid being scratched by the snail. It usually eats some tender leaves and vegetable leaves. Mother told me that snails like to live in wet places, and finally I put them back on the edge of the garden.

Today's observation is really interesting. Different animals have different characteristics. I will also find more information about snails on the Internet.

After the last science class, I still don't want to release my snail and keep it in a bottle. Every time I finish my homework, I visit. Once, I was surprised to find that I didn't know which snail had a baby. I was overjoyed and hurried to inform my sister who was doing her homework.

So from that day on, I became interested in snails. I found that snails leave white mucus where they climb. It has two pairs of tentacles, and its long tentacles have eyes. When I gently touch its shell, it will shrink into a strong little house. It is said that snails have many teeth. Although I didn't open the snail's mouth, I didn't know how many teeth it had, but the book said there were about 25,600, and how many were unclear, as many as the stars in the sky. I am very surprised! How many holes does a snail have? I found three. How can it be three? Then listen to me. One is a defecation hole, the other is a water spray hole, and the last one is a baby hole. As for their position, I need further observation.

Observing Snails Composition 7 Recently, I began to like to observe snails again. If the students are interested, I will continue to write.

Snails like dark and humid places, so rainy days are best. Snail day. In this weather, you can't find snails in the grass at most, so just grab one at will.

The snail caught is as big as a ball; Some are very small, like pearls. However, even though their bodies are very different, they still like to eat vegetables and fruits. One morning, I put a cucumber in the snail's "home". When I came back from school in the afternoon, there was only one cucumber skin left. The snail looked up when he saw me, as if to say, "Master, master, you must give us another cucumber tomorrow!" " "Snails have several interesting places on their bodies-eyes, tentacles and body. Let's talk about eyes first. Snails' eyes will slowly retract into their bodies as long as they touch them, and so will their tentacles. The body will slowly retract into the shell. When a snail crawls, there is always a transparent, slippery and sticky thing behind its body. It's mucus secreted by snails, which can prevent it from falling off the wall, so it will "fly over the eaves" like Spider-Man.

How, after reading this article, do you suddenly feel that small snails are very powerful? Do you think snails actually have many interesting places?

I bought two snails in the flower and bird shopping mall today.

As soon as I got home, I carefully observed the snail and found that the snail's shell was spiral, and the markings on the two snail's shells were different: one was that the markings turned left, which was called left-handed pattern; One is that the stripes rotate to the right, which is called right-hand stripes. Is it funny? They have two pairs of strange antennae, one long and the other short. If you touch its tentacles with a pencil, the tentacles will shrink back with a whoosh.

On the same day, I went to my garden to pick up some leaves and branches, dug up a little wet soil, and then decorated the living environment of snails with these things to make them adapt to the home I gave them.

Snails and I are funny! The fact that I feed snail food is an example: when I first fed snail food, I thought it ate leaves and put it in. But the next morning I saw the snail didn't touch the leaf, and didn't even look at it! I must decorate with leaves. This time, I put another piece of Chinese cabbage, I hope it will like it. I am looking forward to it!

Let me tell you a little secret. In fact, snails are divided into male and female. It is difficult for a snail to be both a father and a mother.

I caught a snail today, and I'm going to take a closer look.

Snails consist of shells. Antenna. Abdomen. Mouth, wait. I gently put the leaves on the snail's mouth. Snails eat slowly. I waited a few minutes before the snail ate half a bite. I touched the snail's tentacles lightly with a pencil, and it immediately took them back. What a coward. I suddenly thought of another question, where did the snail pull the stool after eating? I looked at it carefully and found that it had a small air hole, so I thought, this is probably where snails excrete feces. At this time, I feel that snails are going to excrete feces. I quickly put the snail into a box and saw that it excreted feces from there, as I expected. I thought, do snails eat carrots and watermelon skins? Does a snail have teeth? Do snails move their tentacles when they eat? So, I gave carrots and watermelon skins to snails, and found that snails ate them with relish and saw that snails had no teeth. I looked again and found that when snails eat, their tentacles move.

Snails have so many characteristics!
