Time flies like a horse, and a day has passed. What's your summary? Why don't you keep a diary now? What are the novelty and richness of diary writing? The following is my observation diary (general 10) about eggs soaked in white vinegar, hoping to help everyone.

Observation diary of eggs soaked in white vinegar1Sunday, September 22nd, the weather was fine.

I put an egg in a cup, then pour rice vinegar and soak the whole egg in vinegar. After about 10 minutes, I found that many small bubbles appeared on the surface of eggs, and they became denser and denser, just like soda water just opened. The bubbles were linear and looked like white eggs in an oil pan. An hour later, I observed the egg at this time and touched it with my hand. I found that the surface of the egg was a little peeling. But the egg skin is still hard.

It rained on Sunday, September 23rd.

Get up in the morning and watch the changes of eggs in a hurry. I saw something like a movie floating in the cup. The color of the egg skin has become lighter. As soon as I touched the egg skin, it faded, revealing a lighter egg skin, which became a little soft. The color of vinegar is a little lighter.

Monday, September 24th is fine.

Eggs have been soaked in vinegar for three days, and the skin is still peeling, but there are no bubbles on the eggshell, which has softened a lot. When I gently pinch an egg, I feel a bit like holding an eraser in my hand. The eggshell has cracked. Maybe I pinched it.

Tuesday, September 25th is fine.

Gently press the eggshell with your hand, the eggshell sinks, release your hand and the eggshell bounces back. I feel like a rubber duck when I was a child. The brown film in the vinegar sticks to the edge of the cup, and the vinegar becomes clear and no longer turbid.

It will be sunny on Wednesday September 26th.

In the evening, I continued to observe the vinegar soaked eggs and found that the vinegar became very turbid. It's really weird. When I read it in the morning, it was clear vinegar. Touching the eggshell makes the skin softer. I can't help thinking: is it because of the crack in the eggshell that eggs and vinegar go bad? Did my vinegar-soaked egg experiment fail? In order to find out the reason, I decided to soak an egg in vinegar to solve the problem. ...

On September 27th, I soaked another egg in vinegar. Today, it was observed that vinegar turned into black tea color and eggshells became soft, so a new conclusion was put forward. The last time the vinegar turned cloudy, it was because I accidentally cracked the eggshell and shed a small amount of egg white.

Observation diary of eggs soaked in white vinegar 2 10 June Saturday sunny 1

A few days ago, Mr. Qian asked us in class, "What would happen if we put eggs in white vinegar?" The classroom suddenly exploded and the students talked about it. "It may be cooked!" "The shell will soften." "No, no, the shell will fall off!" "Not only will the shell fall off, but the yolk and protein inside will also turn into water!" I listened with relish and my heart was full of curiosity. I really want to do it myself.

I happily poured the white vinegar slowly into the cup, then took an egg and carefully put it in the white vinegar. The egg was about to swim to the bottom of the cup, but halfway through, it floated up again, revealing a shell, like an island floating in the vast white sea. I gently pressed the eggshell into the white vinegar, but the egg floated again, as if to see the outside world. After a while, many small bubbles appeared on the egg, like wearing a tulle dress, which looked like kiwi fruit from a distance. By looking up the information, I know that the main component of egg shell is calcium carbonate, so soaking in white vinegar will give off a chemical reaction, and the generated substance will contain carbon dioxide gas. I really look forward to what will change tomorrow!

1It will be sunny on Monday, October 3rd.

I can't see any change in the eggs today, but the small bubbles around the eggs have become bigger. I touched the egg with my hand, only to see bubbles left at the place where I touched it, and I also brought a thin silky dark yellow "paper" with a small hole in the middle, which was very beautiful. The place I touched turned a little white, so I gave the eggs a bath with water. The egg turned white immediately, but the armor on the egg was not completely broken by white vinegar, which was a bit hard.

65438+1Wednesday, October 6th, cloudy.

I went to observe the egg and found that it was dressed in white and felt round. The armor on the egg has been completely broken by white vinegar, as soft as a ball of cotton.

65438+1light rain on Thursday, October 7.

The egg is already very white, and there are some net lines on the surface. Put it under the lamp and take a picture. Ah! A miracle happened! Like the golden moon and the mysterious universe planet, it's so beautiful! Roll the egg, and you can see the yolk moving inside. Throw it gently, hey! Eggs bounce like bouncy balls. It was fun! A strange idea suddenly came into my mind: can this egg be eaten after it is cooked? Will it be sour? When you eat it, does it make the sound of "Luo Luo Yi Zi"? This series of questions lingered in my mind. Soak eggs in white vinegar. This experiment is really interesting. It taught me to pay attention to everything.

Observation diary of eggs soaked in white vinegar 3 10 Thursday shower 1

In Chinese class yesterday, Miss Li assigned a special assignment-soaking eggs in white vinegar and writing an observation diary. When I heard this homework, many small question marks popped up in my mind. What will eggs look like after soaking for a few days? Will eggs break? Will eggshells become as strong as Iron Man's armor? With a little question mark in my mind, I began to prepare experimental materials.

I prepared a glass, a raw egg and a bottle of white vinegar. I first washed the glass and eggs with clear water, then poured about 150 ml of white vinegar into the glass, and finally gently put the eggs into the glass filled with white vinegar.

An egg just put in white vinegar is like a naughty child. It dives to the bottom of the cup first, and then floats in the water like breathing.

The thought that eggs have been floating in white vinegar for two days makes me want to take a glass of bubbling eggs and study them carefully after getting up. There are many dense bubbles the size of rice grains on the surface of the eggshell, just like wrapping an egg with plastic wrap. There are some floating objects on the originally clarified white vinegar, and the white vinegar becomes a little turbid.

65438+1It will be sunny on Sunday, October 4th.

On the third day, the egg seems to get bigger and there are fewer bubbles on the surface of the eggshell. At this time, I realized that the egg may not float in vinegar, but it is stuck in the cup because of its large size. I put out my finger and poked the egg gently, and it slowly sank to the bottom of the cup. When my finger touched the egg, I felt the shell softened. I think this is probably the softening effect of vinegar. I still remember that my mother would let me drink a little vinegar if I got stuck with a fishbone while eating.

65438+1It will be fine on Tuesday, October 6th.

On the fifth day, I found that the eggshell became soft. The meat powder on the eggshell surface has fallen off, but the skin powder turned out to be white after falling off. Out of curiosity, I gently touched the egg with my finger. Who knows, some layers of powder and flesh that haven't fallen off have been rubbed off by my fingers. So I kept touching, and more and more objects gradually sank to the bottom of the cup. I was pleasantly surprised to find that there are two irregular "glass windows" on the surface of the eggshell. Through these two "glass windows", I saw the egg white and yolk inside.

65438+1Thursday, October 8th, sunny

On the seventh day, I gently poured out white vinegar and eggs. I found that the white part of the eggshell slowly fell off, and the number of "glass windows" on the eggshell increased. The area of the two "glass windows" in the previous two days also increased. I washed the eggs carefully, and the white layer on the eggshell was washed away quickly. At this time, the egg became a translucent marble, soft and elastic to the touch. Later, I found out that the main component on the surface of egg shell is calcium carbonate, while the main component of vinegar is acetic acid. When they react, they produce calcium acetate and release carbon dioxide. Calcium carbonate is slowly dissolved, so the eggshell is also slowly softened.

What an interesting experiment!

Observation Diary of Eggs Soaked in White Vinegar 4 20xx 65438+February 1 day

Today I'm going to do a little experiment of soaking eggs in vinegar. I took out a red-shelled egg from the refrigerator and found a glass. In order to observe it more clearly, I decided to soak the egg in white vinegar.

I wash the eggs first, put them in the glass, and then pour the white vinegar in until the eggs don't move. Through the glass, I looked at this vinegar soaked egg. Suddenly, something magical happened. Eggs put on "bubble clothes"!

I touched the eggshell with my fingers curiously, and a slight limp and numb feeling came to my mind. Mom said it was a chemical reaction between eggshells and white vinegar. This is really interesting. What will happen next? How I look forward to it!

20xx65438+February 2nd.

When I wake up in the morning, I go to see eggs soaked in vinegar. Look, it has gained a lot of weight. The color of eggshells is not as bright as it was yesterday. The glass mouth is full of bubbles, which have formed a layer of brown sticky things, possibly falling eggshells.

I put my index finger into the glass and gently dipped some vinegar in the egg. Gee, it's amazing that the hard eggshell has become a little soft now. I carefully put the vinegar-soaked eggs on the desk, waiting to see what tomorrow will be like.

20xx65438+February 3rd

Some soft eggshells yesterday have completely turned into soft translucent films today. The size of the egg has doubled!

The hard eggshell is gone. Where did it go? Eggs will get bigger. What happened? With a lot of questions in my head, I looked up the information on the Internet. The reason why eggshells become soft until they disappear is that acetic acid contained in vinegar dissolves calcium carbonate, the main component of eggshells, and the bubbles in eggshells are carbon dioxide bubbles produced by the dissolution reaction. As for the volume of the egg, it will double, which is caused by osmotic pressure. When the concentrations of substances on both sides of the film are not equal, osmotic pressure will be generated, and water in substances with lower concentration will penetrate through the film to the other side, so that the concentrations of substances on both sides of the film are equal. The concentration of protein in eggs is relatively high. After the eggshell is thinned, under the action of osmotic pressure, the water in the white vinegar enters the egg through the translucent film formed after the eggshell is dissolved, thus expanding the whole egg.

Ah, so that's it! Through the scientific experiment of soaking eggs in white vinegar, I learned about the wonder of chemical reaction and the joy of doing it.

Put the eggs on the flashlight and take a photo at night. This egg is as bright as a night pearl.

It is said that eggs soaked in white vinegar will become soft and transparent. Is that really the case? I decided to do it myself.

As soon as I got home, I couldn't wait to open the refrigerator, carefully take out the eggs, put them in a transparent cup and slowly pour vinegar on them. Gee, the egg was immediately surrounded by thousands of small bubbles, floating up bit by bit, wobbling and ups and downs, just like a drunk. After about a minute, the egg slowly poked its head out, revealing a small tip the size of a fingernail.

Into what? I got up the next day and went to see the eggs without washing my face. It is still floating, but there is a brown film floating on it. Is this an eggshell? I take a closer look, and the eggshell is still there! I touched it gently with chopsticks, and the surface of the eggshell was scratched, revealing protein inside. I continued to paddle on the surface of the eggshell with chopsticks, and more protein was exposed, and the egg became a big painted face. White vinegar also became cloudy, so I changed it once.

Today, eggs have given us a change. The hard shell turned into tiny foam, and the small bubbles became smaller. The egg becomes transparent, like a crystal clear amber and a water polo. I gently press it with my hand, and it jumps like a naughty crystal baby, like a ballet in diving, sometimes jumping out of the water and sometimes sinking into the water.

I fished the egg out of the vinegar and held it carefully in my hand for fear of breaking it. I carefully observed that the egg became thin and transparent, like an inflated balloon, which broke when blown. We can still vaguely see the yolk inside. I asked my mother, "Why do egg shells become crystal clear?" Mother said: "raw eggshells contain calcium carbonate, which reacts with acetic acid to produce soluble calcium acetate and produce carbon dioxide gas." It turns out that thousands of small bubbles around eggshells are carbon dioxide gas. I also know that soaking eggs in white vinegar can not only cure cough, but also beautify!

Observation Diary of Eggs Soaked in White Vinegar 6 March 22nd Saturday sunny.

What interesting things will happen when an egg meets white vinegar? Let's experiment, explore and uncover its mystery!

Gently put the egg into a transparent cup, unscrew the cork of white vinegar and sprinkle it evenly on the egg like the seasoning of cold dishes. Suddenly, a strong choking smell rushed to the nose with malicious intent. Needless to guess, everyone knows that this is the unique taste of white vinegar. Look, the eggs are writhing impatiently in white vinegar. It turns out that it doesn't like the taste of vinegar either.

Look! On the slightly rough ball skin, I don't know when countless tiny bubbles appeared. They are restless. From time to time, they form small teams and fly to the surface, eager to get rid of this narrow space. After a large number of bubbles flew away, even smaller bubbles grew on the egg surface, and they became bigger and bigger. From a distance, the whole egg looks like a white fluffy ball and a soft cloud. I couldn't help reaching out and squeezing it. Wow, that's cool! Small bubbles formed an "air cushion" on Zhang. Bubbles shuttled between fingers, itchy and crunchy, and an inexplicable pleasure echoed at the fingertips, making me want to pinch.

The bubbles on the eggs become as big as sesame seeds. They are crowded together, like a white pine cone ball with powder, which makes people want to reach out and touch its head at once. It's like ... at this moment, my father shouted in surprise: "Lele, look, look, the eggs are floating!" " "Really, under the light, the egg is covered with a layer of holy luster, and it is slowly-I think it is very tired and difficult to float in the cup like this. The pointy little hat can't wait to get out of the water first. Hehe, eggs, do you want to get some air and see the outside world?

After waiting for a long time, I really couldn't control the little man named "Curious" in my heart to reach out and gently pinch the egg in the cup, but ... at the same second, I stood at the table at a loss, holding the egg that was about to slip, and shouted incoherently: "Dad ... please, I ... I can't hold it!" It turned out that the egg in my hand seemed very satisfied with the white vinegar bath and wanted to take off its hard coat, but its soft boneless body caught me off guard.

Is it going to "transform"?

It will be sunny on Sunday, March 23rd.

Run to the eggs as soon as you get up in the morning. After a night of transformation, bubbles have grown up a lot. Look, their full bodies are almost comparable to those of red beans, black beans and mung beans.

The most amazing thing is these little bubbles. Looking through the side of the cup, the smooth surface of the egg looks like a shrinking star. What about the transparent bubbles attached to it? Isn't it like a beautiful little house? Hold your head high, as if anxiously waiting for the return of your master. Will their owners be alien elves?

Hey, what's that? Dark brown fine lines are all over the egg's face. Is it the thread carelessly left by a careless mother? I washed them carefully. Ah, where my fingertips touch, white dots are clearly visible. They must have just appeared. They look like footprints left by naughty children on the beach.

I carefully took out the eggs and washed them with fine water to remove the dirt. Under my careful efforts, a perfect "image endorsement egg" has been released! Under the light, the elastic ball exudes a charming light yellow luster, like jade, like amber, and more like a luxury that ancient dignitaries played with. A closer look shows that there is a golden ball hidden in the translucent egg, which rolls with the egg, just like a mini version of "Little Sun". Hehe, it turns out that there is a golden secret hidden in the small egg!

These balls are now completely a standard ball. It can bounce on the table, somersault, and even resist my beating on it. It can be said that it is worthy of the honorary title of "the hero in the egg".

Why can white vinegar transform eggs? With doubts and questions, I opened Baidu. It turns out that the main component of eggshell is calcium carbonate and the main component of white vinegar is acetic acid. When they meet, a wonderful chemical reaction will take place, and the eggshell will disappear quietly in the "war" between them.

Haha, the egg meets white vinegar, and the ending is estimated to be only "ball".

I am in high spirits this day and want to see what happens when eggs are soaked in vinegar. After the preserved egg is peeled off, you can see that its protein is dark green with some patterns, while the yolk is orange-red and feels tender. After the salted duck eggs are peeled off, the protein inside is white, the yolk is golden yellow, the color is bright and it looks beautiful.

It rained lightly on Friday, September 30th.

I took out two eggs from the refrigerator, one raw and the other boiled. I carefully put two eggs in two bottles filled with nine-degree white vinegar, waiting for their changes. Five minutes later, two vinegar eggs floated up, and then many small bubbles appeared, as if taking a hot spring bath, as if to say to me, "This hot spring is really comfortable. Look, I'm bubbling all over. How fun! " Very interesting. I'm looking forward to more changes in vinegar eggs.

65438+1It will be sunny on Sunday, February 2nd.

The next day, I came to see my two jealous eggs again. The bubbles on the vinegar eggs did not decrease. I found that the shell of the raw eggs had completely fallen off, revealing a snow-white belly, which felt soft. However, only two-thirds of the shells of boiled eggs fall off, which is still difficult to feel. I thought to myself: You must hurry to refuel! So why do raw eggs "undress" when soaked in vinegar? I got the answer on Baidu. Com: Because vinegar contains a lot of "acid" substances, "acid" has a corrosive effect, so egg shells can be softened and peeled off.

65438+1Monday, October 3rd will be fine.

On the third day, when I came to see the two vinegar eggs again, I found that the cooked vinegar eggs had completely shown me their chubby bodies, and I couldn't help laughing. When I turned my eyes to raw vinegar eggs, I couldn't help being surprised! I can see that the vinegar eggs in the cup have become transparent, and I can also see the egg liquid flowing inside. I picked up the cup and observed it carefully. It turns out that the vinegar egg has been corroded, leaving only a thin film. I excitedly took the vinegar egg out of the cup. The vinegar egg feels very elastic and jumps into my hand as soon as it is taken out. So cute!

This observation brought me a lot of fun, just as Mr. Lu Xun said, "A drop of water is also a big world under a microscope."

Observation Diary of Eggs Soaked in White Vinegar Chapter 8 Item 1

It will be sunny on Wednesday September 28th.

It suddenly occurred to me today that salted eggs are salty and preserved eggs are transparent. Where are the vinegar eggs? I rushed home at a sprint speed of 100 meters, quickly took an egg in the refrigerator, gently put it in a cup, and then poured in white vinegar with a concentration of 9 degrees.

10 minutes later, I saw that the eggshell was covered with small bubbles, just like little pearls. It's amazing! From then on, I began a long expectation.

Rule number two

Thursday, September 29th is fine.

This morning, my mother woke me up: "There is a layer of powder on the eggshell!" " "When I heard this sentence, I was completely sleepy. I wonder what an egg will look like if it is soaked in vinegar. I immediately got up and ran to the living room, next to the "little egg" and observed it carefully. It is found that the eggs "float" and there will be a layer of powder where the vinegar is not flooded. I asked my mother, "What are those powders? Why is there? "Mom said," These powders should be calcium in eggshells, which will be separated when they meet vinegar. " I nodded and said, "I see. "I also saw the small bubbles originally attached to the eggshell scattered to every corner of the cup and left the little egg base camp.

Rule of Three

It will be fine on Friday, September 30th.

In the afternoon, I took a look at my "little balls" and found that the air inside seemed to have solidified, leaving only a little bubble. I touched the egg lightly with my finger and found it softened and turned into a small ball. When I press it, a hole is recessed, which is very interesting. There is more powder on the eggshell, which forms a circle on the eggshell, just like a small hole. I think this "vinegar egg" experiment is getting more and more interesting.

Rule number four

65438+1It will be fine on Thursday, October 6th.

I went on a trip on the 4th, and went to see my "little balls" as soon as I came back. I was surprised to find that it absorbed all the vinegar! It turns out that the "small ball" also has water absorption function. I carefully observed the eggshell. When I touched it, its powder stuck to your hand, leaving a piece of white where I touched it. Look at the whole egg, almost like a full little fat pig. What a big change in two days! What a surprise!

I looked for the reason of powder in a huge amount of data. As a result, I learned that eggs contain dissolved calcium carbonate, leaving a soft film on the inner layer of eggshells, so eggs will soften when soaked in vinegar. So eggshells produce such powder.

Soak eggs

The day before yesterday, the teacher assigned an assignment ―― soaking eggs in vinegar. During the holiday, my mother and I went to the supermarket to buy more than 9 degrees of white vinegar and some eggs. When I got home, I put raw eggs and cooked eggs in two glass bottles, poured vinegar on them and began to observe. About ten minutes later, raw eggs and cooked eggs began to take off their white clothes.

65438+1Monday, October 3rd will be fine.

bubble

This morning, I came to observe my vinegar eggs again. I found raw eggs soaked in vinegar and cooked eggs floating on it. It is really interesting! And the two of them have been spitting bubbles, one after another, just like children blowing bubbles. In addition, I also found that raw eggs are getting bigger and cooked eggs are getting smaller. How strange!

65438+1Tuesday, October 4th will be fine.

Egg discoloration

At noon, I came home from outside. Suddenly, I found that my vinegar egg changed color. Two eggs of the same color changed from light yellow to dark yellow, and the boiled eggs changed from yellow to white. How cute!

1It will be sunny on Wednesday, October 5th.

Eggs become soft.

Yesterday's eggs changed color, so what will happen to today's eggs? So, I came to the egg. The boiled eggs are unchanged from yesterday, but there are many small white spots on the raw eggs. These little white spots are called calcium, which is very nutritious. Thinking of this, I can't help touching the raw egg to see what it feels like. So, I carefully touched the raw egg, which surprised me at first, because my raw egg turned out to be soft, elastic and comfortable! It's not like before. It feels hard, as if it will break at any time.

This is the result of my observation of vinegar soaked eggs. From then on, I learned to be careful and be a careful little talent.

Observation diary of eggs soaked in white vinegar10 Tuesday, September 27th is fine.

Today, Teacher Deng gave us a special assignment: Let's put a clean and fresh raw egg in a glass filled with 9-degree white vinegar and observe what strange changes will happen to the egg.

So, in the evening, I went home, searched online with my father how to make vinegar eggs, and then we started making vinegar eggs. I took out a fresh raw egg, washed it and put it on the table for preparation.

Let's take a graduated glass, pour 180ml of water into it, and then pour the water from the glass into another glass. Then measure the height with a ruler and mark it, and then pour out the water in the cup. Finally, just pour the 9-degree white rice vinegar into the cup, and when the water level rises to the scale, you can put in the eggs.

When I first put the egg in it, there were many bubbles on it, just like a glittering and translucent gem. After a while, the egg actually floated, but it didn't take long to sink. Then he came up again, sank again, and was unconscious in the water, as if he had lost his way. After a while, the egg began to spin in the water and kept spitting bubbles while spinning. I didn't expect the change of vinegar eggs to be so magical. I will abide by it tomorrow!

It will be sunny on Wednesday September 28th.

As soon as I got home today, I couldn't wait to run to the dining table to see how my vinegar eggs were. Sure enough, the performance of vinegar eggs did not disappoint me. After a day, the vinegar eggs were much bigger than yesterday, and there were more and more bubbles on the water. This means that my vinegar eggs are almost finished, and now I only need to observe them for another day.

Thursday, September 29th is fine.

Today, when I got home, I found that the vinegar egg was a little transparent, so I punctured the eggshell soaked in 9-degree white vinegar with chopsticks at night and saw a red and golden yolk flowing out of it. I use chopsticks to pick out the flat egg shell from the cup, put it aside, and then mix the egg yolk, egg white and white vinegar evenly to form vinegar egg liquid.

Then mother poured some vinegar and egg liquid into the small bowl, and father poured some honey into it. I couldn't help taking a sip, which was sour and sweet. It's a pity that I'm not used to the taste. I only drank a little.

This is really an unforgettable experience!
