Eggs contain almost all the nutrients needed by the human body, so they are called "ideal nutrition banks". Nutritionists call it the "complete protein model". One of the experiences of many long-lived elderly people is to eat an egg every day.

Many health medicated diets circulated among the people in China are also inseparable from eggs. For example, Polygonum multiflorum Thunb boiled eggs, eggs boiled pig brains, egg congee and so on.

Eggs are ideal natural food for human beings, but we should also pay attention to science in eating. For the elderly, cooking, lying down, steaming and tossing eggs are better. Because frying, frying and frying are delicious. But it's hard to digest.

If eggs are processed into salted eggs, their calcium content will increase obviously, from 55 mg per 100 g to 5 12 mg, which is about 10 times that of fresh eggs. It is especially suitable for middle-aged and elderly people with osteoporosis.

Protect the liver

Protein in eggs can repair liver tissue damage. Lecithin in egg yolk can promote the regeneration of liver cells. It can also increase the amount of human plasma protein, enhance the body's metabolic function and rabbit epidemic function.

Prevention and treatment of arteriosclerosis

American nutritionists and medical workers have made amazing achievements in preventing and treating atherosclerosis with eggs. They extract lecithin from eggs, walnuts and pig liver and give it to patients with cardiovascular diseases, 4-6 tablespoons a day.

After 3 months, the patient's serum cholesterol decreased from 1000 mg to 180 mg. This research has attracted the attention of the world medical community. This method has been used in clinical practice in many countries and achieved satisfactory results.

cancer prevention

Eggs contain more vitamin B2, which can decompose and oxidize carcinogens in human body. Trace elements in eggs, such as selenium and zinc, also have anti-cancer effects.

According to the analysis of human cancer mortality in the world, it is found that cancer mortality is inversely proportional to selenium intake. In areas with high selenium content in blood or eating selenium-rich foods, the total cancer mortality rate is lower than that in areas with low selenium intake.

Brain-strengthening and intelligence-improving

Lecithin, triglyceride, cholesterol and yolk protein in egg yolk. It has a great influence on the nervous system and physical development. Lecithin can be released after being digested by the human body, and choline will reach the brain through the blood.

So as to avoid the mental decline of the elderly and improve the memory of all ages. Therefore, to maintain a good memory, whether teenagers or middle-aged and elderly people, just eat one or two eggs a day.

Eggs will float. A 500-word composition is urgent. After I finished my homework today, I had nothing to do, so I did an experiment in which an egg floated in the water.

I prepared some experimental instruments first: a transparent glass cup, a spoon, raw eggs and a big pot of salt.

I first scooped half a glass of water in the cup, and then put the eggs in the cup.

I saw the egg suddenly sink to the bottom of the cup.

Then, I put the salt in the cup and stirred it carefully to accelerate the dissolution of the salt in the water.

I stirred and stirred, and suddenly found that the egg had left the bottom of the cup, but after a while, the egg sank again.

At this time, I put some salt in the cup.

I was about to put it on when my mother came back.

When she saw the scene unfolding on our desk, she immediately nagged, "Look, you're fooling around again, and you're not doing anything serious.

""No, I'm doing an experiment. I am doing an experiment on how to make eggs float in water.

"However, when my mother heard this, she hurriedly handed me a bag of fine salt and said," Fine salt dissolves faster than coarse salt.

"So, I added a few spoonfuls of salt and stirred it gently, and the eggs really floated, and they also surfaced.

I cried happily, "the experiment succeeded, the experiment succeeded!" " "When I was dancing with joy, my mother asked me seriously," Do you know the reason why eggs float? "My mother's problems took away more than half of my happiness. I was really tongue-tied and couldn't figure it out.

But my mother "forgave" me and gave me time to look up the information myself to find the answer.

Later, I found the answer on the internet: when the weight of an object is greater than the buoyancy of water, it sinks; When the weight of an object is less than the buoyancy of water, it will float.

Water has a certain proportion.

When we add salt to water, we increase the proportion of water.

When it increases to a certain value, the specific gravity of water is equal to the weight of eggs, and eggs will be suspended in water; When the specific gravity of water is greater than the weight of eggs, eggs will surface.

It turned out that my mother asked me to add salt to the water in order to increase the proportion of water, so the eggs surfaced.

Hands-on, experiments, brains, and information can really learn skills and acquire knowledge.

How interesting!

Today, the science teacher told us to go home and do the experiment of "eggs float".

When I got home and finished my homework, I couldn't wait to start the experiment.

(2) I prepared some experimental instruments first: a transparent glass cup, a spoon, raw eggs and a big pot of salt.

I scooped up half a glass of water and put it in the cup. Then I carefully put the eggs in the cup. The egg jumped into the cup like a diver and sank to the bottom of the cup, motionless.

Then, I added a spoonful of salt to the cup, but the egg didn't move.

I added two more spoonfuls of salt. Suddenly, the salt dispersed, like the mist when the goddess came down to earth, and the water became turbid. I stirred it hard and saw the egg slowly fly to the middle of the water, shaking its head like dancing, but it turned around and fell again.

I put another spoonful of salt in the cup and stirred it. Soon, the eggs floated! I cried happily, "the experiment succeeded, the experiment succeeded!" " "When I was dancing with joy, my mother came back.

My mother saw me doing the experiment of "eggs float" and asked me, "Do you know why eggs float?" My mother's question left me tongue-tied.

So I asked my mother, "Why?" But my mother asked me to look up the information myself to find the answer.

Later, I found the answer on the Internet: whether an object can float in water depends on its density.

After salt is added to clear water, it becomes salt water. When the density of salt water is greater than that of eggs, the buoyancy of eggs is greater than gravity, and eggs are naturally "supported".

(5) This experiment made me understand the magic of science. As long as we are willing to experiment and think boldly, then we will gain knowledge and reap the fruits of victory.

Write a composition of about 800 words on the topic of digging eggs. Today is my mother's birthday. I thought: can't I fry eggs? Today, I will fry an egg for her to celebrate her birthday.

I came to the room downstairs-a room dedicated to food.

I looked around, not to mention eggs, and I didn't even see the shadow of eggs.

I've looked everywhere, but I still can't find the eggs.

Have my hopes been killed like this? Just when I was about to despair, I had a brainwave: isn't there a hen that can lay eggs in the henhouse? I'll catch one, and then I'll "deliver the baby" with lightning speed, so that the eggs won't fall into my hands. I want to be beautiful.

I came to the chicken pen, holding chicken food in my hand and muttering in my mouth, hoping to attract its attention.

Sure enough, it took me only three rounds to carry the hen away.

I took it to the kitchen and closed the door, thinking, look at you, I'm going to kill you every second.

But reality is always so cruel.

I jumped at the chicken, but it dodged me. I jumped on the stove again. It spread its wings and flew to the other side. As a result, I was covered in dust and dirty.

I said, "I used to play with it, but now it plays with me as a monkey?" I was so angry that I grabbed the chicken leg and tied it with a rope. Although the chicken kept struggling, it was tightly tied by the "demon rope" and I couldn't get rid of it.

So I can do whatever I want.

I put the chicken on the chair, then put my hand under the chicken and waited for the moment when the hen laid eggs.

After a while, the chicken trembled. I thought it was a chicken to be born, and it changed from confusion to sobriety.

Suddenly, a piece of bad news and happiness appeared at the same time: I didn't have an egg on my hand, but a piece of shit.

I let out a scream of "Ah" and rushed to the pool to wash my hands.

It turned out that the hen wanted to go to the toilet, because her feet were tied and she couldn't walk, so she used my hand as a toilet.

You said, I didn't steal an egg, but I stole a piece of shit?

An Egg Composition Yesterday, the teacher asked us to bring an egg early until school was over.

Everyone is puzzled. What is the abacus in the teacher's mind? On the day of painting egg protection, or ... the next morning, I wrapped an egg in toilet paper, and then put the eggs in my "clothes" in several disposable cups, put them in a big medicine box and wrapped them in a bag.

I brought a heavily armed egg on the road.

Walking on the road, at first I held the eggs in the bag, but later I was afraid that I would not stand steadily, so I held the eggs in the bag in one hand and the bag in the other.

Pay attention to the people around you while walking, for fear of bumping into my "key protected object".

Class again, listening to nothing. I just think about my egg, touch it for a while, and open it when I have the chance to see if it is broken.

I always rush out of the classroom like a madman during recess.

But I'm not in the mood to play today, because I want to protect my "key protected object", supporting the table with one hand and protecting the eggs with the other.

At this time, our class has sacrificed a lot of eggs.

Finally, my egg was preserved.

I didn't expect a small egg to make me pay so much sweat.

From a small egg to the infinite care of parents.

How difficult it is for my parents to raise me as a pupil! We are this little egg, and you hatched me from the chicken list.

As an egg, I can't forget my parents' concern for me when I was ill, the moment my parents sent me to campus for the first time, the process of raising me as a primary school student and their painstaking efforts.

Until today, I finally understand why the teacher asked us to protect the eggs. Parents are reluctant to give us food and clothes.

They still love us, although sometimes they are not harmonious. I can't forget the love of my parents.

Planting eggs Composition Planting eggs "As you sow, you reap!" This is a sentence I heard when I was five years old. I asked my mother, "As you sow, you reap." Mom said, "As you sow, you reap. Grow beans.

You'll get beans! After listening to my mother's words, a naive idea appeared in my young mind: "I like to eat eggs." If I plant eggs, I will get a lot of eggs! " I won't worry about eating eggs in the future! "I sneaked into the kitchen, took an egg and ran out of the house. I found a wooden stick on the ground in front of the building and poked it into the soil. I had a hard time poking a hole in the egg place. After I put the egg in, I buried it with soil, then made a mark at the edge of the pit, patted off the soil on my hand and left.

After a few days, the eggs did not germinate, and after a few days, they still did not germinate. I thought, "What's the matter? Why not sprout? I'll ask the eggs.

"I ran to the land to see where the eggs were. I looked anxiously everywhere, but there was no trace of the egg. I thought to myself, "the seeds of the egg tree are gone, my egg!" " "Neighbor grandpa wang came out. I knew he was a master of growing things, so I ran over and asked him, "Grandpa, what I planted didn't germinate, and finally it was gone."

"Did you water it? Grandpa Wang asked, "No.

"I shook my head and said.

Grandpa Wang said, "How can seeds germinate without watering?" "I see.

"I skipped home, thinking," It turned out that watering only germinated, and here I am.

"I took an egg, put it in a small pit, buried the soil, carried a small bucket of water and poured water into the egg pit.

I said to the pit, "Little eggs grow fast and grow into egg trees, so I can eat fresh eggs."

"A few days later, the egg hasn't come out yet. I thought, "Isn't there enough water? "I brought a big bottle, the water inside is too heavy. I had a hard time lifting the bottle. When it fell, the water washed away the soil in the pit.

Huh? Where are the eggs? The eggs are gone.

I thought, "Someone must have stolen my eggs!" " "I thought about it and said," I want to catch the egg thief! " "I hid behind the door, with a stick in my hand, staring at the pit where the eggs were buried, but after waiting all morning, there was no sign of the' bad guy'. I thought, "Didn't someone steal the eggs? Did the egg run away by itself? " At this time, my mother came to invite me to dinner. I told my mother about it. My mother smiled after hearing this ... and finally understood that eggs can't be planted.

Every time I see an egg, I think of this interesting childhood story!

Write a scientific experiment composition about 400 words about eggs, Several Experiments of Eggs. When the freshly boiled eggs are fished out of the pot and taken directly by hand, although they are hot, they are still passable.

After a while, the water on the eggshell dried up and it felt hotter than when it was first caught.

First, how to peel eggshells smoothly?

Because a layer of water film is attached to the newly fished eggshell, the water film evaporates and absorbs heat at first, which makes the eggshell temperature drop, so it doesn't feel very hot.

After some time, the water film evaporated.

The heat transferred inside the egg makes the temperature of the eggshell rise again, so it feels hotter.

Boiled eggs are soaked in cold water immediately, and are taken out and peeled after being completely cooled.

Principle: When an egg is immersed in cold water, the eggshell will contract directly when it is cold, but the temperature of the protein will not drop too much and the contraction is small. At this time, the eggshell will shrink.

Secondly, due to the different properties of different substances, when the whole egg is completely cooled, the protein shrinkage rate of loose tissue is greater than that of eggshells, which leads to the separation of eggshells and makes it easier to peel eggshells.

Second, the atmospheric pressure experiment selects a bottle with a diameter slightly smaller than that of an egg and heats a layer of sand at the bottom of the bottle.

First, light a ball of alcohol cotton and put it in the bottle. Then, block the bottle mouth with the small head of the shelled egg facing down.

After the flame went out, the egg was slowly "swallowed" by the bottle into its belly.

The burning of alcohol cotton makes the gas in the bottle expand by heating, and some gas is discharged.

When the egg blocks the bottle mouth and the flame goes out, the pressure of the gas in the bottle becomes lower than the atmospheric pressure outside the bottle due to the temperature drop.

Under the action of atmospheric pressure, eggs with certain elasticity are pressed into the bottle.

Third, the liquid density experiment immersed an eggshell in a large-caliber glass filled with clear water.

After releasing my hand, I found that the egg slowly sank to the bottom of the cup.

Take out the eggs and add salt to clear water to prepare a high-concentration salt solution.

Then immerse the egg in the salt solution, and after releasing the hand, the egg slowly floats.

The ups and downs of objects depend on the relationship between gravity and buoyancy.

The volume of an object immersed in a liquid is the volume of the liquid it displaces. According to Archimedes principle, the relationship between object density and liquid density can correspond to the relationship between gravity and buoyancy.

Because the density of eggs is slightly higher than that of clear water, when eggs are immersed in clear water, gravity is greater than buoyancy, so eggs will sink.

When immersed in salt water, because the density of salt water is greater than that of eggs and gravity is less than buoyancy, eggs will float.

Fourth, how to distinguish between raw eggs and cooked eggs.

Choose a raw egg and a cooked egg with similar appearance and put them on a horizontal table.

Rotate them in the same place with the same force.

What can spin quickly is cooked eggs, and what stops after a few turns slowly is raw eggs.

There is liquid egg white in the shell of raw eggs. When the external force acts on the eggshell and rotates, the egg white remains still due to inertia, so there is friction resistance between it and the eggshell, which makes the whole egg only rotate slowly.

The egg white in the cooked egg has solidified into protein, and the whole egg can rotate quickly when it rotates under the action of external force.

Fifth, the eggshell tumbler.

Choose a raw egg, make a hole in one end of the small head, and clean the egg white and yolk in the shell.

Slide the weight along the hole.

Take the big end of the eggshell as the bottom and hold the eggshell.

Light a candle, drip candle oil, and seal the heavy object at the bottom of the eggshell.

Candle oil can be sealed to about a quarter of the height of the whole eggshell.

After the prepared eggshell is pushed down, the eggshell can stand up automatically.

Be a "tumbler".

The weight of the seal at the bottom of the empty eggshell and the candle oil make the center of gravity of the whole egg close to the bottom of the eggshell, and the lower the center of gravity, the better the stability.

When the eggshell tilts away from the equilibrium position, the center of gravity of the egg rises.

Because the bottom of the eggshell is spherical, the egg body returns to its original equilibrium position under its own gravity.

Raw eggs cooked eggs ingredients raw eggs cooked eggs raw eggs? Cooked eggs? One Sunday morning, grandma went out to buy breakfast. She hasn't come back yet. There is only one egg in the bowl on the table. When I picked up this cooked egg and prepared to eat it, I suddenly found a basket of raw eggs on the table. It suddenly occurred to me, what's the difference between cooked eggs and raw eggs? I have a raw egg in one hand and a cooked egg in the other.

It seems that you can't see the difference between them at all.

I put down this raw egg, picked up another raw egg and identified it carefully.

It seems that even I can't tell which is the raw egg. Which is boiled egg? What shall we do? What shall we do? I'm hungry, but I don't know which egg to eat. I am scratching my head.

I racked my brains in vain.

It suddenly occurred to me that when grandma was cooking, the broken raw eggs were liquid.

A big egg yolk sank to the bottom of the bowl.

My eyes lit up at the thought.

Raw eggs are filled with liquid. When an egg rolls, the center of the liquid is constantly changing, so there is resistance when it rolls, and it is not so refreshing when it rolls.

Cooked eggs are just the opposite.

I put my two eggs on the table and let them roll at the same time.

I found that these two eggs were confused at first, and slowly.

One of the eggs is spinning slowly.

I seem to be carrying a heavy load, wobbling and unable to turn around.

While the other egg remains flexible.

I think: this kind of elastic egg must be cooked, because after cooking, the liquid has turned into a solid, and its yolk will not produce resistance as the egg rolls.

I picked it up and tapped it on the table. Wow, it's done.

Ha! This discovery surprised me very much.

Hee hee! I'm too smart.

I learned to boil eggs during the holiday.

The experience of boiling eggs is still vivid: 1. Wash the fresh eggs, soak them in a pot of water for one minute, and then boil them with low heat.

After the eggs are boiled on low heat, simmer for 8 minutes.

Boiled eggs should be taken out and allowed to cool naturally, or put in cold water or cold water for half a minute to cool, so it is easy to peel.

For bacterial infection, it should not be put into tap water.

After the eggs were soaked in cold boiled water for a while, I couldn't wait to eat them.

That taste is very unusual.

Because I made it myself!

How to make an egg stand up! Let me talk about eggs in the East and the West. It's silly to drop an egg on the 25th floor. Listen to the beep. Breaking an egg is the same as breaking a brave and fearful skull. It weighs 30 grams. The egg fell on the fourth floor, swollen the bag and broke the skin on the eighth floor. 18. Fall from the 25th floor and kill fragile eggs. Fragile eggs have a fixed height, speed and strength. Don't treat it as weak as an egg Don't treat it as weak as an egg Environment can make hard stones tremble with fear. Question: Let the eggs stand. Let the eggs drift. Let the eggs stand up. Tap the top of the egg and break it. Let the eggs stand up. Eggs are banned. The price of destroying eggs is cruel injury. Let the eggs stand up like molds. Put the eggs in the mold and limit them moderately. Let the eggs stand up as support. Let the egg stand up, stand up. I should choose the right one. I invite you two to hold the eggs hard. I found that I can hold the egg very hard. Let's see if I can hold it very hard. As for holding an egg, I can knock it flat and shake hands gently, so that I can hold it with all my strength. I can knock the eggs flat. The goal set seems to use the goal set of strength to exert the egg power. The egg shakes hands, and the palm almost wraps the whole egg. I shook hands and spilled the whole egg. It seems that I use my strength to disperse my eggs. I let my whole body break through the thin eggshell. I saw the obstacle itself and broke through it. In fact, there are two ways to break eggs. Another way is to let the egg break itself from one end of the egg and from the outside. Eggs will destroy themselves. Break the eggs yourself, break them yourself. Eggs hatch by themselves, and a new life-chicken eggshell is hatched in the eggshell. Chickens peck through eggshells, break out of eggshells and break their original selves. Eggs want to be broken by external forces, just like eggs break, accumulating internal forces, breaking through, surpassing, realizing and regaining the hope of new opportunities.

The eggs are floating. Accompanied by the sweet music in class, Mr. Lu walked into the classroom with light steps, smiled at us with a lesson plan, turned around and wrote on the blackboard, "Can eggs float on the water?" A few big characters.

As soon as I finished writing, my classmates began to talk about it.

Some students asked inexplicably, "How can an egg float when it is so heavy?" Some students said as confidently as Zhuge Liang: "Since Teacher Lu said so, so can I!" Teacher Lu stopped us with a gesture and said to us, "Seeing is believing. Let's answer this question with experiments.

"The experiment began. Teacher Lu asked Xie Yuting to take out a transparent quilt, and then went to the water cooler to get a glass of water.

And magically took out several packages of spices: soy sauce, vinegar, monosodium glutamate, pepper and salt.

Then let me take out an egg. I put the egg in the cup carefully. The egg swam as deep as a diver and soon sank to the bottom of the cup.

The students stared at the eggs with their eyes wide open, waiting for a miracle.

Teacher Lu asked us to put the seasoning in the cup.

For the first time, we put soy sauce, vinegar and pepper into the cup, and then stirred it evenly, but the baby's eggs still didn't move; Then we add monosodium glutamate, vinegar and pepper in turn, and nothing happens after stirring; Then add soy sauce, monosodium glutamate, pepper, and the baby eggs still don't move.

This is worrying the whole class.

This baby egg is a little lazy. The sun is shining, and it is still sleeping.

Teacher Lu said slowly, "Don't worry, don't worry, take a closer look at the following experiment."

"Teacher Lu took out a bag of salt, poured it into the cup, and then stirred it evenly with a ruler. This naughty egg floated and sank like a round puffer fish trying to "stand up".

Teacher Lu continued to pour salt into it, and the egg floated upright, revealing a smooth little head.

Teacher Lu kept pouring salt into it and stirring it with a ruler, and the egg magically surfaced.

Perhaps it was because of exhaustion that I fell asleep after swimming.

Seeing this scene, the students swarmed and looked at the baby egg curiously: "Why is this? How can it float? " Teacher Lu told us earnestly: "Why is this? Because eggs are denser than water, they will sink in the water.

When salt is added to the water, the density and buoyancy of the aqueous solution increase and the eggs can be "lifted".

"It seems that from a small scientific experiment, you can also learn knowledge!

Please indicate the source for reprinting. An essay on the benefits of eggs.
