Usually, my parents cook us a lot of rice about eggs, such as egg soup, fried eggs, stewed egg brains and so on. These are all our favorite foods, but students, do you know that an egg can be eaten besides the yolk, and the eggshell is also useful! ! ! If your glass cup or bottle is dirty, you can break the egg shell in half, then put it in the cup or bottle, cover it and shake it, so that your bottle will be as good as new.
Oh, by the way, this is the bottom of your pot. Some parents are obsessed with cleaning, and the burnt place at the bottom of the pot is hard to get. Don't worry, just crush the eggshell and rub it back and forth. Isn't it simple? What? Is your plastic basket dirty, too? Don't worry, as long as you put the broken egg shells in socks and wipe them back and forth in the basket, your basket will become clean! How about eggshells? They are very useful. In fact, as long as you are good at discovering the little things in life, life will be very interesting in your eyes.
By the way, I'll tell you a delicious drink-egg honey juice. You pour the juice into the cup first, then add the milk and honey, and finally add the egg yolk to stir, and a cup of delicious egg honey juice will be fine! Why don't you try it at home? It is delicious.
2. Composition of making twelve things with eggshells There is a lonely little eggshell in the stinking garbage dump. It used to live in the refrigerator and blow air conditioning, but now it seems that it has come from heaven to hell.
Days passed day by day, until one day, in the tropical storm warning called "Bliss", the strong wind with heavy rain approached the garbage bin where the little eggshell lived. The strong wind wrapped the little eggshell and its partners unscrupulously. After running all the way from day to night, they came to a distant place. "Bao Qisi" sent the small eggshell to a clear river.
After washing away the dirt in the clear river, the small eggshell lay on the soft and fluffy grass, smelling the fragrant breeze and was taken back to its nest by a bird.
Birds use small eggshells as bowls for dolls. Although this kind of life is a bit boring for the small eggshell, it is full and happy inside. It watched the bird grow up day by day and felt the greatness of life. Finally, the birds and dolls will leave their mothers and live alone. They kissed the little eggshell and sent it back to the grass. At this time, the little eggshell is a little reluctant to leave these lively, lovely and clever birds, and it is almost in tears.
Later, the small eggshell became an ant's boat, a cradle for small crickets and an umbrella for small beetles. ...
Small eggshells help one small animal after another. It lives among its partners and finds life meaningful. I am a happy little eggshell. I am much happier helping others, and I am happier giving than taking.
If you give me an eggshell to write a composition, there will be an interesting little experiment on Sunday. I did an experiment with my classmates in the interest class.
Teacher Liu from the interest class came into the classroom with a big smile on her face. "Students, have you brought all the eggshells?" "I brought it!" We answered with one voice.
"But what can eggshells do?" "Be a tumbler?" We whispered to each other. "Today, we are going to do a small experiment with these two and a half eggshells.
Please guess before you do it. I poke the eggshell vertically with this pencil. Which eggshell will break first? ""Mouth down will break first! "Most boys pointed to half a shell and said," Keep your mouth up first! " Xiao Xue said flatly.
Many girls are sitting and hesitating. "That's great! Let's do it and see whose answer is correct. "
The teacher turned to a classmate for help. He put his mouth against the teacher's hand and pointed a pencil at the eggshell. As soon as his hand was released, the pencil fell on the eggshell, which was not broken. The second time I dropped the pencil, but it fell into the teacher's hand, and then fell to the ground. pencil lead broke it.
The teacher took out another pencil, this time she made it herself. The pencil was dropped only twice, and the eggshell with the bottle mouth up was broken. Then, the teacher picked up the pencil and poked the eggshell with his mouth down.
"Once, twice, three times ..." We counted them together, but this half eggshell is like wearing a diamond armor, and it won't break after being stabbed nine times. "long live! I guessed right! " Xiaoxue danced with joy.
"good! Next, I will let the students do it themselves to see if this is an accidental phenomenon. " "Yes, don't be too proud!" We don't believe it.
Later, the teacher said: "The same two and a half eggshells are tied vertically with a pencil, because the downward eggshell is concentrated, so it is easier to be tied;" The eggshell with its mouth down is scattered and not easy to be punctured. "We suddenly realized that it is no wonder that workers on construction sites usually wear face-down helmets. It turns out to be a truth! This experiment not only helps us learn scientific truth from it, but also enriches our horizons.
My mother said to me, "If you hold the egg in your hand, no matter how you pinch it, it won't break." I listened with a grain of salt: the eggshell is so thin that it will "break" with a light tap, let alone a hard pinch. Try everything, only what you have tried is the truth. Then I will do a small experiment to prove whether the eggshell will break when I hold it in my hand.
Gossip hands-free, do it right away. I carefully took an egg, put it in my hand, and slowly closed my palm, for fear that once I clenched it, the egg white and yolk inside would splash out like a fountain, and then my clothes would suffer. However, the experiment must be carried out. I slowly clenched my hand into a fist, and the tighter I held it, the tighter I held it. At this time, my heart is like fifteen buckets of water-seven ups and eight downs. But this egg is as hard as a stone, and there is no trace of cracking. Hey, this egg didn't let me down. This is a crucial moment to witness whether the eggs will be crushed. My heart is pounding with excitement. I clenched the egg hard, but nothing happened. This second time, I tried my best to suck milk, but the egg was like a hard shield. This is really great! Strong curiosity guided me, and I asked my mother with a full stomach of questions. My mother said: "The shell of an egg belongs to an arch structure. When it is subjected to external pressure, the force can be evenly distributed on the surface of the eggshell. When you hold an egg with your whole hand, the stress on the eggshell is large and the pressure is low, so no matter how you hold the egg, it won't break easily. It is this principle that makes the robust Zhao Zhouqiao so powerful. " After listening to my mother's explanation, I suddenly realized that eggshells are really wonderful!
It turns out that eggshells have such a mystery. We really should pay attention to the things around us, and we will always find something and gain something. You always ask questions at the end of everything you do. If you don't understand, do the experiment yourself, and you will always find the answer to the question. Only the result of the experiment by yourself is the best answer.
5. How to write a composition with pictures of egg shells? School will be over on Thursday night. The teacher suddenly said, bring an egg on Friday. Suddenly I felt very puzzled: "What eggs do you want to bring? Do you want us to learn to cook scrambled eggs tomorrow? " What medicine does the teacher sell in the gourd? Later, I learned that we were trying to protect the eggs from breaking. "What's so hard about it? How can a good egg be broken without touching it? I think.
Although the task is simple, I will carry it out seriously. I must be a qualified egg keeper, otherwise, I will feel sorry for the mother hen who gave birth to this egg.
As soon as I got home, I chose eight eggs with good quality. Choose the one with the thickest shell and wrap it with paper towels and cotton (so it will be as big as an ostrich egg)
As soon as I arrived at school the next day, I heard my classmates shouting, "Whoever dares to touch my eggs, I will fight with him!" " "I really love eggs like life!
In the end, my egg was still intact. In the last class, the teacher asked the students to tell their own tricks to protect eggs. Some students put the eggs in a small box, then put a sponge around the eggs and cover them. Some students, like me, almost always wrap the eggs, so that even if the eggs are broken, the egg liquid is not easy to flow out. The teacher said that we were protecting ourselves, not eggs. But Zhou Ying in our class is not protecting herself, but really protecting the eggs. She made an egg protector for eggs. Set up a pyramid-like shelf with iron wire, put the egg in the middle, fix it with rope, and then wrap it in plastic foam, and the egg protector will be ready. Not convinced, we did an experiment-put the egg protector down from the fourth floor to see if it would break. We ran to the first floor like wild horses, waiting for Zhou Ying to throw the egg protector. The fourth grade students downstairs saw it inexplicably.
After a while, Zhou Ying went up to the fourth floor and left her masterpiece behind. Several girls screamed. The egg fell to the ground, and everyone gathered around to see "broken, broken!" "Several students inside shouted first. I walked over and found it was broken. The egg liquid flows out from a corner of the egg protector.
The experiment ended in failure. It turned out that a rope was loose. Although the experiment failed, we threw it away happily. At the same time, this activity taught me a truth. Some things seem simple, but in fact there is a lot of learning. As long as you think more, explore more and discover more, success belongs to you.

6. How did the eggshell become soft? In Chinese class, our teacher's atmosphere is very active. The students stared at the small cups on the platform with wide eyes and watched the teacher do the experiment of dipping eggs in vinegar.
The teacher first put a shiny oval egg into the cup, and then poured a large half bottle of vinegar into it. Then he said, "We'll see the reaction of the experiment tomorrow."
The next morning, I got up early and went to school happily with my schoolbag on my back. I am not allowed to fly to the teacher at once to see the reaction of the experiment. The * * * of Chinese class finally rang. I saw the teacher come into the classroom with a smile on her face. Let's wait in line to see the reaction of the experiment. When it was our turn, at first glance, the luster of the original eggshell disappeared. I touched the eggshell with my hand again.
What is the reason? The teacher seems to have guessed my question. She said kindly, "There is lime in the eggshell. When lime touches vinegar, it is destroyed, so the eggshell becomes soft." The teacher also gave us examples from life. For example, why do you use vinegar to cook ribs? Why do you have toothache when you eat sugar at night? Now I understand the function of vinegar.
This little experiment has added new knowledge to us.
7. What can egg shells do? Wonderful use of eggshells (2)
1. Treat female dizziness. Stir-fry eggshells with slow fire, grind them into powder, mix them evenly with licorice powder, and take 5g of them and take them with appropriate amount of yellow wine twice a day.
2. Treat diarrhea. 30g of egg shell, 9g of tangerine peel and 9g of endothelium corneum Gigeriae Galli are decocted in a pot and ground into powder, and 6g is taken with warm water three times a day for two days.
3. Make a stove. Crush the eggshell and wrap it in paper, which can be used to make a fire in the stove. The effect is very good.
4. Kill ants. Eggshells can be ground into powder after burning and scattered in the corner to kill ants.
5. Drive away slugs. Dry and crush eggshells and put them around kitchen walls and sewers to drive away slugs.
6. Grow flowers. Pour the water for cleaning eggshells into flowerpots, which is helpful for the growth of flowers and trees. Crushing eggshells and putting them into flowerpots can not only keep moisture, but also provide nutrients for flowers.
7. Let the chicken lay more eggs. Pouring eggshells into powder and feeding them to chickens can increase the egg production of hens without laying soft-shelled eggs.
8. Prevent calcium deficiency in poultry and livestock. Eggshells are baked and ground into powder, which can be mixed into feed to prevent calcium deficiency in poultry and livestock.
8. Changes in the composition of eggs In a science class, we learned about the changes in the nature and form of substances.
This makes me understand: the change of material properties means that objects have new materials; The morphological change of matter is that no new matter is produced. After class, the teacher assigned us another task, that is, to do an interesting experiment to see what happened to a raw egg and a glass full of vinegar. Is it a change in nature or form? I went straight to the kitchen after school.
First, I chose a shiny oval egg, put it in a glass, and then put vinegar in the glass to ask the vinegar to overflow the egg. Then I put it on the table and wait for the result tomorrow morning. The next morning, I went to see my experiment with eagerness and curiosity.
I was suddenly surprised to find a string of bubbles around the egg. These bubbles are small and dense, almost covering the eggs. Can't wait to pick up the egg, it's really "I don't know if I don't take it, I'm shocked if I take it."
Touch it with your hands, and you will find that the eggshell has softened after soaking all night, and you have to let it go from time to time. Suddenly, I found the eggs floating out of the vinegar again.
Strangely, I pressed the egg with my hand, and it sank to the bottom of the cup again, but after 30 seconds, the egg slowly floated up again. I carefully took out the eggs, wiped off the bubbles in the eggshell and put them in vinegar.
Ah, the egg sank again! After a while, the eggs were covered with bubbles and floated again. "What is the reason?" I can't help asking my questions.
So, with those questions, I went to the computer, a treasure house of knowledge, to explore the mystery. It turns out that eggshells are soft because eggshells contain a lot of calcium carbonate, and vinegar is a weak acid. Calcium carbonate will generate calcium hydroxide in the presence of water and gradually react with vinegar, so the content of calcium carbonate in eggshells becomes less and softer.
The reason why eggs float repeatedly is that they sink under the action of gravity, but the main component of eggshell is calcium carbonate, which will react with acetic acid to produce carbon dioxide, so that the eggs float again, and the floating eggs will sink under the action of gravity. In class, I explained the process of the experiment to the teacher, and I also understood the truth that "everything on paper is shallow in the end and I never know how to do it".
Only by asking questions in learning and in middle school can we soar freely in the sky of knowledge and seek true knowledge.
9. The magical eggshell ingredient is Ding Lingling. When the bell rang, our science teacher, Mr. Zhu, came to the classroom and said, "We will do a little experiment in this class."
I saw Teacher Zhu take out two and a half eggshells and a sharpened pencil. The students began to discuss noisily.
Teacher Zhu said, "What experiment can two and a half eggshells do?" The teacher said very seriously, "Now the experiment begins." So the students stare big eyes and look carefully.
I saw Mr. Zhu put two eggshells with one mouth facing up and the other mouth facing down, then picked up the sharpened pencil, held the eggshells with their mouths facing up in his hand and dropped them vertically with the pencil. Once or twice, there was a hole in the eggshell.
Teacher Zhu holds an egg shell in his hand, with his mouth facing down, and lets the pencil fall, once, twice and three times.
It took twelve times to break the shell. Teacher Zhu said, "Students, do you know what this is?" The students said a lot, but none of them were right.
The teacher said to us: "The eggshells on the mouth are concentrated and easy to break;" The egg shell with its mouth facing downwards is arched, and the force is scattered, so it should not be fragile. "I heard, an epiphany.
I think that the hats worn by workers on the construction site are also made according to this principle. Bricks and dangerous things are not easy to get hurt when they hit their heads, and there are arch bridges built by ancient people. Humans are really smart.
