Salt water floating eggs excellent essay 300 words Part 1

One day Mr. Hu asked us to do an experiment of salt water floating eggs. After doing my homework I was excited to start this little experiment.

I prepared these experimental equipment: a raw egg . A chopstick. A cup of water. A cup of water. A packet of salt.

I prepared these equipment: a raw egg. a chopstick. a cup of water. a packet of salt.

First of all, I take a raw egg carefully into the water, only to hear the "fluttering" sound of the egg quickly sunk to the bottom, so I put a spoonful of salt into the water, eh? How no movement ah! Then I continuously into the 5 spoons of salt, salt into the water for a moment, I found that the egg floated up a centimeter, I was very excited! I was so excited! But soon the egg sank again. Then I simply took the egg out and put it on the table, and then put the opposite side of the chopsticks in the water and stirred it a few times. I thought: wait until the salt melted, the egg must float ah, otherwise the experiment may fail.

Finally, I put the egg into the water again. The egg finally floated, and also revealed a small "head" it! I was so happy: "Mom and Dad! Come and see, I've done it!" Mom and Dad ran to see, said in unison: "Son, you're great!"

The "salt water floating egg" experiment is really wonderful ah!

On the way home, I heard my classmates say: "Salt water can actually float eggs." I went over and asked my classmate, "Can salt water really float eggs? I don't believe it." The student said: "If you do not believe it, go home and do the experiment."

The student said: "You just need to put a little more salt in the water, and then step by step to do, first take out a cup larger than the egg, but can not take a cup too big, otherwise you have to put a lot of salt." Then I put the eggs in and added a few spoons of salt. But the egg didn't listen to me and wouldn't float. This is what we can do?

I thought, "Why do eggs float in the sea? It's because the sea is buoyant, and that's why the eggs float. But I had already put in a lot of salt.

Suddenly, my mom came over and said, "Son, what's bothering you?" I said: "Mom, I put the salt in the water, and then put the egg in. But why don't the eggs float?"

Mom said, "Maybe the salt hasn't melted yet." I took the eggs out and stirred them with chopsticks, and the salt melted. I put the egg in, and it floated right away. I was so happy that the egg finally floated!

"Wow!" Today, our school is going to hold an activity. It's neither an airplane folding nor a running race, it's called: Floating Eggs. Everyone heard all the cheers, the material? Please look down!

The materials are: a pair of chopsticks, a bottle of water, and a packet of salt and an egg.

The teacher put an egg into the water. In a few moments, the egg "bang" jumped into the water. Shake their fat belly sleep in the cup. The teacher took out salt and chopsticks. The salt was poured into the water, and the chopsticks began to stir, and the egg turned faster and faster like a small gyroscope, and still slept lazily after stirring. The teacher poured all the salt into the water. At once, the egg was like a swimming ring. Immediately floated, the students applauded, the students said the teacher did a good job.

The students asked: "Why will the eggs float?" Teacher said to us: "In the water with salt, the density of water is greater, the buoyancy also followed by greater, the egg also floated."

"This experiment is really interesting ah!" Not only is it interesting, but it's also a learning experience.

Salt Water Floating Eggs Excellent Essay 300 Words Part 4

I wanted to verify that the eggs can float in salt water. I prepared the materials for the experiment: salt, a cup, an egg, water and chopsticks. First, I put some water in a cup, sprinkled some salt on it, put the egg into the water and waited for the result. When I saw the egg at the bottom of the water, I was as disappointed as a deflated ball. I picked up the egg with chopsticks, added salt, stirred it with chopsticks, and put the egg into the water again with nervousness and hope, and found that the egg was still lying dead in the water. I had to fish it out again, or continue to add salt, stir, add salt, stir, add salt, stir when I began to doubt that the experiment can be successful, the egg actually floated in the water, I was excited bad, and then I tried to use chopsticks to poke him, the results of which just touched the bottom of the water on the "thump" and floated up.

It turns out that if you add salt to the water, then the density of the water will be greater than the density of the egg, the egg will float, the experiment was successful, I'm so happy! And this time I figured out the "eggs in salt water can not float" thing, so very sense of accomplishment!

Salt water floating eggs excellent composition 300 words Part 5

I heard that the salt water can make the eggs float to the surface of the water, I don't quite believe it, I want to do a test.

I first prepared a cup of water, a packet of salt and an egg. Preparation is complete, start to do the test.

First of all, put the egg into the water, only to hear the "winter" sound, the egg sank to the bottom of the water, motionless, like a sleeping doll. Then, I put a spoonful of salt in the water, the tiny grains of salt quickly sunk into the water, disappeared without a trace in a short while, "doll" is still sleeping under the water. I put four spoons of salt into the water, some salt sank to the bottom of the water, I used chopsticks to gently stir a few times, the salt melted, the eggs quietly floated up some. Then I continued to put salt into the water, every time I put a spoonful of salt, the eggs jumped up a little, like a doll jumping rope. After adding five spoons of salt, the "doll" revealed her pointed little head, the egg shell around the emergence of many small bubbles, "doll" seems to be saying: "really breathable ah!

This is why? Dad told me: "The density of water is less than the density of the egg, so the egg will sink to the bottom of the water; the density of salt water is greater than the density of the egg, so the egg will float up."

By doing this experiment, I understand: as long as you think carefully, observe carefully, and practice boldly, you can explore more mysteries.

Today I did an experiment at home: called salt water floating eggs. This experiment requires very simple utensils, specifically: a glass of tap water, a spoon, a bulging egg and some salt.

The experiment began, I first picked up the egg into the water, only to see the egg quickly sunk. I took out the egg, put some salt in the cup and stirred hard, the water in the cup became cloudy, I put the egg into the cup, the strange thing is that this time the egg did not sink to the bottom of the cup, I was very surprised, I put some more salt, salt, while stirring, the egg floated a little bit, but not yet completely floated, and I put the salt to continue to stir, then the original cloudy water became clear, then the egg left the bottom of the cup! Exposed the surface of the water, like to breathe the air outside, too magical, why is it so? I was puzzled. Later, my mother told me the scientific reasoning: the original in the water add salt, the density of water will increase, buoyancy will increase, so the original sunk in the bottom of the cup of eggs in the salt water will float up. Eggs will "dance" in the salt water.

The experiment made me realize that science is everywhere. If you're interested, try it!

Today, I did a "Salt Water Floating Eggs Experiment". It was very interesting.

To do this experiment, you need to prepare a raw egg, a pair of chopsticks, a glass, a jar of salt and a small spoon. First I carefully poured half a cup of water into the empty glass. Then, I gently put a raw egg, which quickly slipped into the bottom of the glass, like a brown bear lazily lying unwilling to move. Then I added salt to the cup, and after stirring gently with chopsticks, the salt slowly melted into the water. I was staring at the cup, but the egg still didn't move, I think I put too little salt in it. So I scooped several spoons of salt into the cup one after another, and continued to stir gently with my chopsticks until the salt slowly melted all the way through, and I watched intently, my heart in my throat. Suddenly, a miracle happened - the sleeping "brown bear" was finally awakened and wobbled to the surface. The experiment was a success! I couldn't stop waving my little fists upwards, jumping up and down with excitement.

This experiment let me know - the buoyancy of salt water is greater than the buoyancy of water, the egg will float in salt water. This experiment not only let me harvest the happiness, but also let me harvest the knowledge, really benefit a lot!

Sunday afternoon, I saw the "salt water floating eggs" experiment on the Internet, I was confused, ready to do this experiment.

Before the experiment, we have to prepare the materials: a transparent glass, an egg, a chopstick, a spoon and a packet of salt. I prepared the materials, I can not wait to do the experiment, mom is also in the side of the expectant look at me.

The experiment began, I first poured half a cup of water into a transparent glass, and then gently put the egg into the water. The egg is like a small stone, shaking to sink to the bottom of the cup, not moving. I realized that the water could not make the egg float at all. Then, I began to add salt to the water, I took a spoon and put three spoons of salt into the cup, the salt slowly drifted into the bottom of the cup like a snowflake, and then took out chopsticks and stirred and stirred and waited for the salt to dissolve, I stirred and stirred and found that the egg slowly floated up. I was happy and shouted: "Great, I've done it."

Mom also ran over to praise me: "Children you are great!" I asked my mom curiously: "Mom, why fresh water can not let the eggs float, but salt water can?" Mom said to me: "Because salt water than fresh water buoyancy."

Oh, so that's it! Science is amazing.

Today, the students are particularly excited in class, because the teacher will give us to do "salt water floating eggs" experiment.

First, the teacher prepared a transparent cup, an egg, some salt and a spoon.

The experiment began! The students stretched their necks, eyes wide open, full of expectation to watch the teacher. Only to see the teacher first put an egg into the cup of water, but the egg is like a stone to the bottom of the water, then the teacher added three spoons of salt, stirred, salt like snow like scattered in the water, the water from the transparent and clear into milky white, but the egg is still stubbornly lying in the bottom of the water, not moving. The students were very puzzled, thinking: Can this experiment be successful? Only to see the teacher is confident, not panic and added 6 spoons of salt, the egg finally floated up, revealing a piece of naked scalp, like a small island. The students cheered with joy: "Wow! It's great, it worked, the egg floated up, Oye!"

The teacher revealed: "Add salt to the water, increasing the density of the water, increasing the buoyancy of the egg, so the egg floats.

What an interesting experiment! We usually have to observe more, think more, hands-on practice, you will find a lot of magical things waiting for us to find.

Saturday, we in the large language classroom, with the teacher to do an interesting and fun experiment, called "salt water floating eggs".

First, we poured half a cup of water into the glass, and then poured in a spoonful of salt, we carefully put the egg into it, but the egg has not floated. Could it be that the salt is too little, we poured three spoons of salt into the glass, the water became cloudy, but the egg has not floated, as if a baby, lazily lying at the bottom of the glass, I was a little disappointed, thinking: "Is this experiment is a lie? But can not give up halfway ah! So we added two spoons of salt to the cup, watching the salt melt a little bit, a magical scene happened, the baby eggs finally shook and floated up, like a drunken drunkard, I was happy, looking at the magic water, could not help but drink a mouthful, mama! This is too salty!

After that, the teacher told me: "Add salt to the water, the buoyancy becomes greater, the more salt added, the greater the buoyancy, the egg floats!

After this experiment, I want to do more experiments, this experiment is really amazing!

Saturday we did an interesting experiment with Mr. Dong, began a wonderful scientific journey.

First I put the white eggs into a transparent glass, pour clean water warm water, if poured particularly hot water, the eggs in the water will certainly be scalded, if poured into cool water, salt is not easy to melt. Then I used a spoon to scoop a spoon as snowflakes like salt, slowly poured into the water, the eggs did not float, but we were confident, because we know: failure is the mother of success! So, we repeated the action, hey, to the sixth spoon, the egg slowly floated to the center. "Wow, we got it!" We can not help but cheer up, the seventh small spoon when finally revealed the small head of the naked, we are happy and jumping.

Unexpectedly, Mr. Dong actually thought out of the blue, painted on the egg with two big eyes and a big long mouth, I couldn't help but say: "Teacher, I want to ask, this is the devil's face?" The students laughed.

It turns out that as the amount of salt increases, the egg slowly floats, and this experiment also tells us one thing at the same time: as long as you work hard, you will be successful.

This morning I saw in the program "one of my extracurricular books" a reading master made a salt water floating egg experiment, I want to try it, my mother is very supportive.

I found a transparent water bottle, an egg, a large spoon, a chopstick, my experiment is ready. Then I put the egg into the water bottle, filled it with water, and the experiment began.

At first, the egg was sunk at the bottom of the bottle, I followed the example of the TV to add salt to the water, and then stirred with chopsticks. Stirred for a while, the egg is still sinking to the bottom of the water, I was a little anxious, mom said the concentration of salt water is not enough, let me not be anxious, slowly.

I added salt, and then stirred, even added three times, the egg finally slowly began to float, so happy!

I added salt and stirred again, three times in a row, and the egg slowly began to float, so happy!

After the experiment, my mother told me that this is a physical phenomenon: because the concentration of salt water is large, the buoyancy of the water on the egg increased, and when the buoyancy is large enough, the egg floated up. This is a really interesting experiment! Science is really fun and deep!

Do you know this little experiment of salt water floating eggs? It is not only interesting, but also contains scientific truth.

Before class, the teacher said, "Today we will do the experiment of floating eggs in salt water." The words just fell, we are happy to dance, high-five. The teacher took out the prepared materials: an egg, a packet of salt, a chopstick and a cup of pure water. Soon the experiment began. Minjun first carefully placed the egg against the wall of the cup and slowly lowered it down. The egg jumped into the water with a splash like a diver. At this time, it was like a huge pearl, entering the "dreamland" at the bottom of the sea. Everyone saw that the egg quickly sank to the bottom of the cup. At this time, Ye Sen slowly poured the salt into the water, Yu murmured to pick up a chopstick, the precipitation in the bottom of the cup of salt stirred evenly. After a while, the water in the cup slowly became cloudy and the egg floated up. But when the stirring stopped, the egg sank again. When people saw this, they talked and argued. Many people thought that the egg could not float, but some students believed that the egg could float, so Yu murmured and started stirring again. Unconsciously, a few minutes passed, the egg finally slow, wobbly wake up from the dream, put his head out of the water, as if to see the wonderful world outside, we are happy to jump three feet high.

I know from this experiment: after adding salt to the water, the density of the water becomes greater, the buoyancy also follows the greater, the egg floats up.

Today, I did an interesting experiment, it is called "floating eggs". I first took out a transparent bowl that had been prepared. In the light, the bowl is particularly bright, radiating light, my mood excited! After adding enough water to the bowl, I then took out the egg for fear of breaking it, so I carefully put it into the water, almost without even a sound.

Next, I put in the right amount of salt, which mixed with the water and made it cloudy and fuzzy. But I found that the egg milk like a lazy baby asleep, I was anxious, afraid that the egg will not float. When I use chopsticks to stir, surprised to find that the egg floated up, and it is like a dancer, dancing in the water, after a while, it seems to dance tired, and lazily back to the bottom of the water to sleep."

After a while, "the egg floated, I succeeded!" I was happy and dancing like a flying kite.

But what is the principle? My heart is full of questions. So, I mustered up the courage to ask the science teacher. The teacher said: "Because the salt can increase the buoyancy, so, the egg floats." I suddenly realized, it seems that there are many small knowledge in the world, can be found through small experiments. In life, there are not know how to be careful to ask, every scientist is through the solution of small problems slowly success.

Today we did a thrilling experiment in the classroom, our teacher in order to let us write a good essay, so we did a small experiment in the classroom.

We do this experiment to: "a cup, a pair of chopsticks, an egg and a bag of salt, the teacher first took out a transparent glass bowl that has long been prepared, to the bowl poured most of the bowl of water, and then, the teacher's hand holding the egg, holding the egg, carefully put the egg into the water, the egg in the water, the teacher's hand is also in the water, for fear of breaking the egg, the teacher let go of the hand. The teacher loosened his hand, the egg is still sleeping, sleeping very well, then, the teacher added a little salt in the water, with chopsticks in the cup, stirring, the egg woke up from his sleep with all his strength to swim upstream, but how to swim can not swim up, plus more salt, and then more water, or did not float up, the experiment failed.

We thought the bowl was too short, and replaced it with a taller one, and experimented again. At that important juncture, we stared at the cup, finally succeeded, the egg floated, our teacher used a ruler to poke the egg, the egg and potentially the bottom of the cup to sleep, not for a while, and floated up, poking out the little head, breathing fresh air.

We were very happy, shouted: "Success!"

We were so happy that we shouted, "It worked!" This experiment was very memorable for me.

The principle is that salt water is more buoyant than fresh water, so the egg can float on the salt water.

Salt water floating eggs excellent essay 300 words Part 16

I saw a strange experiment in the book, it said that the egg into the water, and then add salt, the egg floats, I was skeptical. I was skeptical. So I was ready to explore and find out the truth.

I came to the kitchen with curiosity, took out a glass bowl, a small bag of salt, an egg and a pair of chopsticks, and then poured the water into the bowl, I was careful to put the egg into the bowl, I did not see to what changes. I was very disappointed when the egg dipped to the bottom of the bowl and lay motionless on the bottom of the glass, but when I was about to give up, a light flashed in my head: "Oops! I have not put salt!" I rushed back to the table and added a little salt to the water, waited for a while, and then poured the salt into the water, stirring with chopsticks as I poured, "wow! It was like snowing in the cup, and it was pouring from the air to the ground. The "little fat man" in the water woke up from his sleep and slowly floated up to the murky water surface, revealing his smooth little head, which was so cute! At this time, I took the chopsticks out of the water, I gently touched the smooth "little head, pressed it into the water, I found that I let go, the egg from the bottom of the water and floated up, this is really interesting! But how to make it float up? It turns out that because salt water is more buoyant than fresh water, you can make a lot of things are floating, so you can hold the egg up.

The experiment worked, and I was happy because it taught me something.
