Egg swimming essay, how to write an egg essay that can swim

How to write an essay on an egg that can swim as follows:

When class started, the Chinese teacher walked into the classroom with a smile. Take out a pair of chopsticks, a cup, a packet of salt, and an egg and place them on the lecture desk.

Teacher, what is this for? The students looked at the teacher in confusion and discussed.

The teacher is going to practice holding eggs with chopsticks in the classroom! ”

It is estimated that the teacher will give us a live performance of scrambled eggs in a cup. ”

You're not right, the teacher is going to show us how to dance with eggs. ”

In the curious eyes and discussions of the students, the teacher picked up the egg and said to the students secretly: "Eggs can swim, do you believe it or not?" ”

What? Can eggs swim? Make no mistake! ”

Everyone opened their mouths wide in shock, and their faces were not in disbelief.

The teacher picked up the transparent cup, poured half a glass of water into it, and gently placed the egg in the teacup. As soon as the egg plunged into the water, it sank directly to the bottom of the cup, not moving, like a child sleeping at the bottom of the cup.

The eggs didn't swim, and the classmates looked at the motionless eggs in a daze.

The teacher said, "The time has come to witness the miracle. ”

When the students heard this, they all stared at the eggs in the cups with wide eyes, but the eggs still didn't move.

The teacher picked up the salt bag, poured some salt into the cup, and stirred it with chopsticks. The egg in the cup kept spinning in the cup, and when the rotation stopped, the egg was still lying at the bottom of the cup, and there was no movement. The miracle didn't happen, and everyone laughed.

At this time, the teacher also smiled and said, "Today's egg is very naughty, it will be tricky, look at the master's methods." With that, he continued to pour salt into the cup. This time, the egg slowly floated up, finally revealing its little head on the surface of the water, and rolling on the surface of the water.

Swimming, really swimming! The class burst into applause.

Looking at us who were excited, the teacher revealed the secret: the reason why eggs can swim is because after adding salt to the water, the buoyancy becomes larger. There are many things that can be done by using the buoyancy of water.

It turns out that buoyancy has such a magical effect.

I was eating eggs this morning, and my mother smiled at me and said, "Feifei, do you think eggs can float on the water?" "When I heard this, I almost threw up all the eggs, how could the eggs float on the water.

So what if I had a way to make an egg float on the water? "If you let the eggs float on the water, I'll, I'll write my name upside down." ”

Okay, you said it. Mom is full of confidence'said".

So, my mom and I got up and did this interesting science experiment.

My mother told me to prepare my tools: two eggs, two hundred milliliters of water, two empty cups and a packet of salt. I wonder why I take a packet of salt.

What does it have to do with eggs and salt? I couldn't figure it out, so I asked my mother, "Why does mom take salt?"

Mom smiled mysteriously and said, "You'll find out later." ”

Mom first took one of the water cups for an experiment, brought the cup over, and then carefully put the egg in it. The egg did not float on the surface of the water, but kept sinking slowly in a circle until it sank to the bottom. I smirked and said

How's that, eggs can't float on the surface of the water for years! "Don't get complacent too soon, the best is yet to come!" I saw my mother take out another cup, put an egg in it, and then put a little salt, but the egg still did not float, and then put salt until I poured out half a bag of salt, and the egg began to float up slowly!

I excitedly said to my mother, "Mom, you are so amazing! "It's not that mom is great, it's a scientific principle.

So my mother told me about the scientific principle: the specific gravity of clear water is not as important as that of eggs, and the gravity of eggs is greater than the buoyancy of water on eggs, so eggs should sink in clear water; If salt is added, the specific gravity of the brine is greater than that of the egg, so the buoyancy of the brine on the egg is greater than the gravity of the egg itself, so the egg will float in the salt water. ”

Oh, I see. "Fifi. "Huh? "About the thing that your name is going to be written backwards......"Oops, Mom! ”

Eggs can swim, and if you say this, I'm afraid you'll have to laugh off other people's big teeth. But, I believe.

One day, Mom was cooking. Suddenly, she walked out, still holding an egg in her hand, and said to me mysteriously, "Eggs can swim, do you believe it?"

When I heard this, I immediately laughed and said, "What? I heard you right, eggs can swim, I don't believe it.

You really don't believe it? I confidently said to my mother, "I don't believe it!

Mom laughed: "I haven't done the experiment myself, don't jump to conclusions!" So, the mother put down the chicken and foolishness, smiled and walked away.

I sat in my chair and looked at the egg, picking it up and putting it down. After struggling with my heart for a long time, I finally decided to do an experiment myself.

I went to the kitchen to get a big mug and started experimenting. I filled the cup with tap water and carefully put the eggs into the cup. I saw the egg plunge into the cup, sticking to the bottom of the cup like a magnet.

At this time, the egg is like an old man, unable to move. I angrily said to my mother, "You lie, eggs don't swim at all."

Mom smiled and said, "You didn't give the eggs a float." "What floats?

That's – salt. "Mom brought me the salt.

I'm a little confused, what did my mother give me salt for? Is it going to be put in the water? I put two spoonfuls of salt in the water and stirred gently, but the egg didn't appreciate it and remained motionless.

I didn't give up and put another spoonful of salt, but the egg still didn't move. I was frustrated, but I was not reconciled, I wanted to see the eggs swim too much. Could it be that I don't have enough salt?

So, I continued to add salt to the water, one, two, three ......With the salt'As it increased, the weight of the bright egg seemed to begin to lose, and it reluctantly left the bottom of the cup and floated upward. I added more force, but when I added eight spoonfuls of salt, the egg jumped from the bottom of the cup to the surface of the water like a mischievous child. I was ecstatic and shouted:

Mom, eggs can finally swim! ”

It turns out that with a hands-on try, science can be so wonderful.
