2. Composition "Ants Not Scared" Weekly Notes (seven days) Title: Ants not scared are watching TV at noon today, and a popular science story is being broadcast on the program: ants will not die if they fall from the sky.
After reading it, I was dubious: if a person falls from the sky, he will not die, but he will also fall to death. What magical power does the little ant have to let it escape? I went to the ant cave with questions, trying to catch an ant and find out. I held the ant in my hand and thought with a smile: Now I can finally know this problem, haha.
But when I wasn't paying attention, the little ant flew away like the wind. However, it didn't know I would step on it.
I was very sad when I saw the ants being trampled by me. Lift your feet and leave, and the ants actually move again, climbing forward step by step.
Ah! It's amazing! I happily picked up the ant, raised it above my head, and then let go. I quickly squatted down to observe the ants.
Not bad, still climbing step by step. I think: it is definitely not high enough.
So I moved a chair, climbed it carefully, and then "dropped" the ants according to the previous steps. Ah! He must be dead this time.
I rolled and crawled down from the chair and saw the ants lying motionless on the ground. It turned out that it was wrong on TV.
That's what I thought. Suddenly, the ant moved again.
I saw it. I can't believe my eyes. From this incident, I understand a truth-there is knowledge everywhere in the world, which can only be seen by careful observation.
3. An essay about why ants don't fall to death 600 Ants are a common insect and easy to identify. Generally, the body is small (0.5mm-3cm), with four colors of black, brown, yellow and red, and the body wall is elastic, smooth or hairy. Chewing, the palate is developed. The antenna is knee-shaped, with 4~ 13 nodes, long-handled nodes and 2~3 nodes at the end. The abdomen 1 or 1 and 2 are knotted. Winged or wingless. The front foot has a large spacing and is comb-shaped. It is a corner cleaner (used to clean tentacles). But why can't he fall and die?
So, I did an experiment. I caught five or six small ants. Put them in a test tube. Then I surrounded a piece of land with building blocks and wrapped it in paper to prevent the ants from being thrown outside. After that, I started the experiment.
I threw it from 1.3 meters, and I'm still alive after a closer look. Then my brother came over and said, "What record?" I said, "Not bad, I succeeded for the first time, and I'm still alive. Yes, you help me write it down. " Later, I did the second experiment. After throwing it away, I found that he did not move. So I called my brother and he said, "Maybe he's playing dead." Sure enough, after a while, he climbed, and I did it for the third time, and it was still the same. It turns out that ants really don't fall to death.
So I went online to find the reason: the secret that ants don't fall to death is actually this: when an object moves in the air, it will be resisted by the air, and its resistance is related to the surface area of the object in contact with the air. The smaller the object, the greater the ratio of its surface area to gravity, that is, the easier the resistance is to balance with gravity, so that the falling speed will not increase, that is, tiny objects can fall in the air at a small speed, so ants will not fall to death when they land.
We can also imagine a way to make ants fall to death (of course, this operation is inhuman and only theoretically analyzed): put ants in a long vacuum glass tube. When ants fall into this pipe, because there is no air resistance, if the pipe is long enough, ants may fall to death.
4. Why don't ants fall to death? Ants are one of the three "social insects" in the world, and they are also the most abundant and widely distributed creatures on the earth. They like to live in groups in their nests. Although ants often appear in our lives, we have not studied them carefully.
In my childhood, ants were frequent visitors. They always appeared in front of me from time to time. One day, I saw ants again, so I thought: Did ants fall to death? I immediately caught the ant, walked to a large clearing and fell heavily. Ants fell to the ground like dandelions, turned over and ran away. What happened? Why don't ants fall to death? That height is a skyscraper for ants! Am I wrong or accidental? I still don't believe that falling can't kill you! Then, I caught an ant and fell to the ground even harder. The result is still the same, but what happened? Are ants gods or am I not strong enough? By rights, they should fall to death. However, it is useless for me to guess here. I have to check the information. So, I went back to watch "100,000 Why" and found out why ants don't die when they fall. It turns out that all objects will be affected by air resistance when air moves, and the size of resistance has a great relationship with the surface area contacted by objects. The larger the surface area of an object, the greater the buoyancy, and the easier it is for air resistance to balance with the gravity of the object, thus making the falling speed of the object slower and slower, that is, tiny objects can fall at a very slow speed when they land. I think: not only ants can't die, but also many animals can't die. This experiment made me understand the relationship between air resistance and objects, and the reason why ants don't fall to death. I also get a lot of happiness from it. I will study hard and become a scientist in the future.
Now that the mystery is solved, I have done another beautiful thing. I found that there are many wonderful places in nature, waiting for us to explore and discover. Now that science is so developed, we can learn more knowledge, such as nature, biology, astronomy, geography and so on. In the past, people were always afraid of many natural landscapes. Through the efforts of scientists, many phenomena have been discovered and explained, making people no longer afraid. Therefore, we should believe in science, support science, popularize science and lead people to get rid of superstition. In this beautiful 2 1 century, science is everywhere, so we must explore and discover many natural landscapes. Here, I want to say: I love science, I love nature! I hope that scientists in China can make important discoveries. In the future, I will also make a contribution to China!
5. Mystery of fairy ant composition 150 When I was doing my homework at home, a dark ant strolled in front of the table. I screamed with fear and decided to throw it to death. Then I picked it up angrily and slammed it on the ground, but the little ant fell to the ground like a feather, turned over and escaped safely.
I think it's strange that such a high place is a skyscraper for a little ant, but why didn't it fall to death? Curiosity drove me, so I took a heavy stone and put it on the ground outside the building. I ran to the fourth floor in one breath and threw the little ant on the big stone on the first floor. I think the little ant is dead this time.
But the little ant landed on the big stone slowly like an airborne soldier, and I was dumbfounded at once! I picked up the magnifying glass and saw that the ant was not dead. Look at its calm and arrogant appearance, it must be saying, "You just can't kill me, haha!" I can't figure it out. I must investigate. So, I found a computer to be my assistant, and looked it up on the Internet. It was a big deal.
It turns out that any object falling in the air is not only attracted by the earth, but also affected by the resistance of the air to it. Ants are very small. When landing in the sky, the attraction of the earth is very small. When the ants land, keep their balance and ensure that their six feet land first. Therefore, the ants are safe and sound.
I am very curious about this matter, which makes me understand a truth-you study hard everywhere.
6. Why didn't the ants fall to death? One noon, I was about to have lunch when I suddenly saw some ants moving rice grains. When I bounced the ants to the ground one by one, I said, "You nasty little things." After the ant went down, it didn't fall to death. Won't ants fall and die? I asked my mother and she shook her head.
On Sunday, some friends and I caught some small ants to do experiments. We started the experiment at five meters. As soon as the ants arrived, they ran away in a panic. This is done several times in a row, and the feet land first. Don't small ants fall to death, and big ants fall to death? We caught some big ants. We first spread a piece of white paper on the floor, then went to the third floor and threw it down one by one. Ants all jump down, and their feet land first.
What is the reason? I'm confused. My father seemed to read my mind and told me why ants wouldn't die if they fell. Besides two long tentacles, ants have six furry feet. Its six furry feet are more than four times its height. Ants are light because they are small. Coupled with the buoyancy of the air to it, those six furry feet may have played a balancing role. So when the ant lands, its six feet are like six springs, which cushion the body and keep the ant from dying.
It suddenly dawned on me that ants are protected from falling.

7. Why don't ants fall to death? 300 words in the afternoon, I saw a few ants. They seem to be out of date and are looking for teams everywhere.
I took the opportunity to start playing with them. I picked up an ant and threw it on the ground. I guess I must have thrown it. I don't even know my home. I looked down and saw that this little guy was fated to run away. I began to suspect that such a small ant fell from such a high place and didn't die! In order to solve this mystery, I caught a few ants and fell several times, each time getting higher and higher, and the result was still the same. The ant is safe and sound.
I think such a small ant falling from such a high place is no less than jumping from a place dozens of meters high. People will fall to death, but why are ants so tenacious? I was confused at that time. Just when I gave up, I saw the chicken bought by others. I was ecstatic when the chicken feathers fell off and landed lightly on the ground. I finally know that the air must have resistance to the falling light ants, and the ants' six legs keep sliding to adjust their balance! In order to be more correct, I checked the computer. It turns out that the six legs of ants can also play a buffering role, so that they will not die if they fall.
Through this research, I finally solved the mystery, and I realized that life is science. As long as you observe, you will always find something.

9. Why don't ants fall to death? 400 words 1. The gravity of an ant is equal to the air resistance it receives.
He will land at a constant speed.
He didn't fall fast enough to kill him.
2. The ant itself is light in weight, and it will encounter air resistance when landing. Plus its gravity and air resistance (buoyancy), the downward force it receives is very small!
3. Life physics tells us that all objects moving in air will be affected by air resistance, and the magnitude of resistance has a great relationship with the surface area of objects in contact with air. The smaller the object, the greater the ratio of its surface area to gravity, that is, the easier the resistance is to balance with gravity, so that the falling speed of the object will not be faster and faster, that is, the tiny object can fall at a slow speed in the air, so the ant will be slow when landing and will not fall to death. On the contrary, the larger the object, the smaller the ratio of its surface area to gravity, the more difficult it is to balance the resistance and gravity, and the faster the object falls, so people will die or even die if they fall from tall buildings. Even so, we can imagine a way to make ants fall from the sky and die: put ants in a long vacuum glass tube. When ants fall in this long vacuum glass tube at normal speed, they will fall faster and faster because there is no air resistance and they cannot balance with gravity. If the vacuum glass tube is long enough, ants may die. Similarly, when the pilot parachutes, because the open umbrella increases the resistance, it is in balance with the gravity that the pilot receives, so that the pilot's landing speed will not be too fast, and he can reach the land safely without falling.
