Learning in life
Learning is not only reflected in science, but also in life, which is just ignored by everyone. As long as you have the heart, you will find it. I found a knowledge-peeling eggs.
After dad cut the onion, he brought out a bowl of boiled eggs soaked in water and said, "Xiaoye, help me peel the eggs." I'll give it to you later "I cheered and took the egg off. Hey, it's really easy to peel! It'll be all right in a minute. Does everyone know what this is all about? Let's ask my father! "Dad, why are eggs easier to peel when soaked in hot water? ""Well, in many things, most substances have the property of' expanding when heated and contracting when cooled'. But each substance expands with heat and contracts with cold differently. Just like an egg, when the temperature changes little or evenly, there is little difference between the eggshell and protein, but when the temperature changes sharply (the current temperature is less than the temperature of the egg or the current temperature is greater than the temperature of the egg), the contraction pace of the eggshell and protein is inconsistent. "Do you understand?
What happens if you heat the eggs in the microwave oven? Eggs, with or without shells, should not be heated in the microwave oven. Because there is a film outside the yolk of the egg, the temperature of the egg rises rapidly after heating, generating a lot of steam, and then the steam will break through the yolk film and explode! So please don't do this!
Next, I'll teach you a "quick' undressing' method" for an egg!
1, prepare a fresh-keeping box, which must be well sealed and watertight.
2. Put the boiled eggs in the crisper, and then add cold water. Water should not be higher than eggs.
3. After sealing the lid, grab the crisper by hand and shake it vigorously for three minutes.
After three minutes, after opening the lid, you will find the eggshell floating on the water, but the egg is intact.
How's it going? Not bad! There is a lot of knowledge in life that you need to find, so act quickly. These are rare gems!
Composition 2: "Writing about Learning in Life" 800 words Writing about Learning in Life Disobedient Table Tennis "There is learning everywhere in life. As long as you pay attention to observation and are good at thinking, you can learn a lot of knowledge." The teacher always tells us this. At first, I always thought life was trivial.
How can you learn knowledge when your trifles are not worth mentioning? But since that incident, I realized the mystery of this sentence. It was a Sunday, and my father and I were playing table tennis. My mother cheered us on and commented on us like a commentator. Suddenly, I hit a "spin ball", which caught my father off guard. "Oh, I won 1 1 6!" My voice just fell. The table tennis shot into my glass with a bang. I was about to pour the table tennis out when my father shouted "slow" and stopped me. Dad smiled mysteriously: "Hehe, now please' please' this table tennis with your mouth." Huh? That's the problem? Dad came up with such a "childish" question to test me. Then I'm sure I can fix it as easy as blowing off dust! I lowered my head, held my breath and blew hard. But this table tennis is like a naughty child wandering at the bottom of the cup, and there is no intention of coming up at all. I was anxious and thought: Is this table tennis possessed? Anyway, I managed to keep blowing into the cup. But table tennis seems to be deliberately against me, twitching, or hovering at the bottom of the cup. Just as I was scratching my head to find a way, my father smiled.
Say, "What's going on? Give up! " That was really "aggressive". I couldn't think of any way, so I had to give up. "Look carefully! Look at my magic qigong! " It's a miracle that my father blew hard at the edge of the cup horizontally and the table tennis suddenly bounced out! I think it's strange. Isn't the way I blow it better than dad blowing it to the mouth of the cup? I never thought I could blow it out like this. I leaned against my father: "Tell me why, it's amazing!" " "Dad took a sip of water and told me that when blowing into the mouth of the cup, the flowing air put pressure on the mouth of the cup.
When the intensity becomes smaller, the pressure in the cup is greater than the cup mouth, the air naturally flows to the cup mouth, and the table tennis comes out along the airflow. Oh, this little table tennis has such profound scientific knowledge. Although I still don't understand what my father said, I really understand the profound truth contained in the sentence "There is learning everywhere in life".
Composition 3: "Learning in Life" 700 words Life is beautiful. It is not only full of happiness, but also full of all kinds of interesting knowledge.
I remember once, my mother and I set off by car to go shopping in Wanda Shopping Mall. When I came to the platform to wait for the bus, I found a strange billboard: If you want to cook rice, go to Fanwang. I thought to myself, "How do you pronounce this word? This question is hovering in my mind. I scratched my head and thought about it, but I just couldn't figure it out. I looked up at my mother, pointed to the billboard in the distance and asked, "Mom, did you see that billboard?" By the way, what is the word "herringbone plus one meter"? "When my mother heard this and saw this word, she frowned and said to me shyly," I'm sorry, little baby. "Mom doesn't know how to pronounce that word!" At this time, my mother stopped for a while, thought about it, and suddenly said with surprise, "Hey, dear, didn't you bring a dictionary?" You can use it to check! " "I thought: hey, mom seems to be right, I can look it up in the dictionary! I immediately took down small backpack, took out my dictionary, turned to the radical search method, and finally found the word: "Hmmm, pinyin dí? In other words, the meaning of buying rice is extended to buy. When I read it carefully, I sighed, "Oh, I see! "
Finally, the two of us got on the bus. I took out a book "Reading Friends" from my bag and watched it to relieve boredom. At this moment, I met a word I didn't know. "This word is very strange, how to stay on both sides? ! "My mother stuck her head out when she saw me sigh. When she saw this word, she smiled and said to me, "This word, pronounce méi, is used to describe people who are stupid, stupid and naive. How about it, it was thundered by this word! " As soon as I listened, I read the book carefully and laughed: "Haha, I was really moved by this interesting uncommon word!" " "
There is learning everywhere in life, see if you can find it; Look around, look! I was almost shocked by this word! You have such words around you. Come on! Have a look around. Maybe you will find them, too! ! !

I see. The golden cicada will shell.
That night, I followed my mother to catch a cicada, but I didn't expect to catch a cicada that was about to shell. I didn't know how the cicada became a cicada before, but this net made me understand.
At first, we turned on the flashlight and looked under the tree. We came across this molting cicada. I thought its shell was still alive, but my mother said, "Its shell is dead. Look at it. It is the top of the cicada in the dead skin. What a coincidence! Let's see how cicadas shed their shells ~ "So, I carefully took the cicadas that just started to shed their shells and quickly ran to the bright street lights to observe them carefully.
I found the cicada's head moving very slowly. Slowly, a thin crack appeared on its back. When it moved, the crack widened a little. One minute, two minutes, three minutes, the crack is getting bigger and bigger. Every time you move, more yellow and tender cicadas come out. After about twenty minutes, the cicada's back is gradually exposed, and its wings are gradually exposed (like two small green leaves. At this time, its strength seems to be getting bigger and bigger, and it keeps shaking. After about ten minutes, its whole body finally
I emerged from the shell, and my wings slowly spread out, from small leaf buds to small petals. The light yellow dress he was wearing turned into a gray-green coat.
"How can it change color?" I'm confused. Mother said, "It is tender in the shell. As long as it is blown by the outside air, its skin will gradually harden, and as soon as it hardens, its color will gradually darken. " I asked my mother again, "Why isn't this cicada black?" My mother said, "It won't get dark until tomorrow morning." At this moment, mother looked at her watch. It's almost ten o'clock. We took the cicada home, put it in a breathable bag and went to bed.
The next morning, when I went to see it again, it had turned black. I called my mother and we observed it for a while. After knowing the whole process of cicada's shelling, we happily put it back into nature.
Today, I am really happy, because I finally understand the meaning of "golden cicada shelling". I have grown into a university again.

Composition 5: "Learning in Life" 500 words Learning in life is everywhere, as many as leaves on a Millennium tree. As long as you are willing to explore, you will find that life is so wonderful. Let's go and have a look ~ no one would have thought that toys are also learned, but I found them. Once, I stayed at home doing nothing and playing with my bamboo dragonfly. I stood up the leaves and rubbed my hands hard, and the bamboo dragonfly flew like a helicopter ~ but I thought about why it flew, and I picked up my precious encyclopedia. It turns out that the leaves of bamboo dragonflies are inclined, allowing air to flow when they turn. Because the blade is inclined, it changes the downward airflow, and the lift generated makes the bamboo dragonfly take off. On the contrary, if you turn it upside down, it will fly downward. How interesting ~ you can try it. It turns out that toys have so much knowledge ~ they can actually make helicopters take off ~ knowledge in life is like stars in the sky; Like sand in the desert; Like water drops in the sea, countless. In the future, we should "play with our thinking and learn by doing." Looking for good knowledge in life ~
Instructor: Lin Comments:
Life is full of knowledge, the key is that we lack the eyes to find them. In this article, the author discovered the knowledge of toy bamboo dragonfly-flight principle. Although the article is short, there are many highlights, especially the beginning and end. Metaphorical sentences, parallelism sentences and final sublimation sentences are all brilliant places.
Composition 6: "Learning in Life" 400 words Learning in life
One day after dinner, I leaned back on the sofa and watched cartoons. My father came over and patted me on the shoulder: Dear daughter, help my father wash the ashtray. I got up and looked, wow, what a dirty ashtray, and there were some soaked cigarette butts floating on the water. Picking up the ashtray, a choking smell of smoke stung my nostrils. Dad, why do you always pour water into the ashtray and make it so dirty? Dad smiled shyly at me. I angrily took the ashtray to the balcony and poured the water from the ashtray into the chrysanthemum basin.
The next day, I happened to find that the little black aphid on the chrysanthemum was missing. A closer look shows that all the aphids are dead, and the small body is lying in the flowerpot. How did this happen? Is it because I poured it into the flowerpot last night?
To prove this idea, as soon as I got home in the afternoon, I put down my schoolbag and took the initiative to help my father clean the ashtray. Like yesterday, I poured the water from the ashtray on a flower with aphids, and then I watched the reaction of aphids intently. At first, the aphid didn't do anything. After a while, they got a little fidgety and started crawling around on the flower branches. A few hours later, I found that some aphids died on the branches and leaves, and some died in flowerpots. It turns out that the water from cigarette butts is actually a good medicine for aphids. I danced with joy for this. Now, if the flowers at home have aphids, I will soak some cigarette butts and spray them with water to ensure that the medicine dies. This unexpected discovery made me understand that there is knowledge everywhere in life. As long as you observe with your heart, knowledge is around you.

Composition 9: 600 words on learning in life 600 words on learning in life Little Eggshell University Q Hehe ~ The sun came out from the west, and the Chinese teacher actually started to do experiments. Strange ~ strange ~ the teacher used the same sharpened pencil and put it at a certain height, which fell vertically in the eggshell with the opening facing up and the eggshell with the opening facing down in turn. As a result, the open eggshell was broken, but it was still intact after being hit several times. "Oh, my God, what's going on?" The students' eyes widened in surprise and turned into a buzz. In order to further verify the experimental results, the teacher asked us to operate by ourselves. At this time, I can't hold it for long. I can't wait to pick up the first eggshell and buckle it on the table. Then I hold the tip of the sharpened pencil with my right hand and put it at a height of about 3} j cm from the eggshell, so that the nib is perpendicular to the eggshell. I put down my pen and fell, and the pencil fell to one side with a bang. I picked up the eggshell and studied it. "Ah ~" The eggshell is really intact. I thought there was something wrong with my eyes, so I rubbed it and did it again and again ... but as a result, only small black spots were left on the surface of the eggshell, but the naughty eggshell was unscathed. Admire ~ admire ~ then, I picked up another eggshell and put its mouth up on the table, in order to

Let it stand upright on the table, I will fix it with my left hand, use the same pen and hit it in the same way. The result surprised me. The eggshell paid a painful price for this sneak attack kiss, and it was injured. The result is exactly the same as the teacher's. Hey, what is the reason? The mystery in our hearts is getting stronger and stronger. Finally, the teacher unveiled the secret of eggshell for us. It turns out that the stress on the eggshell with an upward opening is concentrated at one point, and the force will not be dispersed, so the eggshell is easily broken. The inverted eggshell is not easy to be broken because it is arched, and the force can be evenly dispersed around. Alas ~ I didn't expect the problems of college to be hidden in a small eggshell.

Light the stove
This morning, grandma took out the stove at home and prepared to make it. Just as grandma was about to make a fire, my sister came over. She wouldn't let grandma do it, so she wanted to try the stove herself.
My sister first took a piece of wood from the bungalow and broke it into several pieces. Then she brought me the pine cones she picked up a few days ago, put some on the bottom of the stove, put the wood blocks on it, and finally put the coal on the wood blocks.
After all this was ready, she took the paper and put it on the stove to make a fire, but it didn't light. She had to take out the pine cones under the stove and replace them with specially dry pine cones, then fill the stove and light it, but it still didn't help. Now she is in a hurry and sees her walking around the stove. I just wanted to help, but I saw her go into the back room. After a while, she took out a bottle of white wine. She jerked up the bottle cap and poured some into the stove. This time, she lit a fire and finally lit it ~ however, the fire was too small and soon went out, and the stove was still not lit.
At this time, grandma came back. Seeing the smoke in the room, she hurried to the front of the stove, pulled the bottom of the stove open and lit it again. After a while, I finally heard it.

The "whoosh" burning sound grandma explained to my sister and me the reason: the stove should be lit from below, and the vent should be opened to help burn.
There is so much knowledge in the cooker. It seems that we should ask more questions and learn more in life to avoid making mistakes.
