Write a 600 word essay on the topic I found out

I discovered a way to distinguish between raw and hard-boiled eggs.

There is no difference between raw and cooked eggs in appearance. If you accidentally mix them up, is there any way to separate them? You don't have to use such a stupid and stupid way as cracking the eggs one by one to determine which is raw and which is hard-boiled!

One morning, I was reading at home while my dad was busy in the kitchen. I don't know when the **bell rang, and my father came out to pick it up and said to me: "Linlin, my father is in a hurry, I want to go to the unit immediately, my mother is not at home, you have to watch the door."

Also, yesterday my grandmother accidentally put some hard-boiled eggs into the basket where the eggs were placed, so that there were both raw and hard-boiled eggs in the basket, can you separate them? It would be great if it could; If you can't help it, don't touch it. Dad hurried away after saying that.

I went to the kitchen and looked at the basket of eggs, thinking back to the tone of my father's voice. I thought to myself, is this going to stump me? So I desperately searched my mind for everything I could know about eggs; The eyes are desperately searching for clues to distinguish between raw and hard-boiled eggs; The nose desperately smells the different smells of raw and hard-boiled eggs.

Alas, it took a lot of effort to distinguish which one was raw and which was cooked.

I was dejected and ready to continue reading, but the thought of my father's words "If you can't help it, don't touch it" made me more competitive, and I said to myself: Can this little thing stump me? You say I can't help it, I'm going to break it up.

So, I poured a glass of water and sat down to take a break before continuing to divide. When I sat down, the hand holding the water accidentally shook and the water in the cup shook with it. So I put the cup on the coffee table and noticed that the water in the cup was still shaking.

I looked at the water, and then at the eggs, I had an idea, there was a way, this glass of water gave me a lot of inspiration: you can use the effect of inertia to divide raw and hard-boiled eggs!

So I put the egg on the coffee table, then rotated it quickly, and then held the egg down with my hand, and then the egg would stop. After the egg stops, immediately let go of your fingers, if the egg stops moving, it means that the egg is cooked; If it continues to spin, the egg is raw.

This is due to the action of inertia, raw eggs are liquid inside, while cooked eggs become solid during the cooking process. Although the shell of the raw egg does not move, the liquid inside has not stopped, so let go of your fingers, and the liquid will rotate the eggshell again; This is not the case with hard-boiled eggs, because the hard-boiled eggs are solid inside, the eggshell does not move, and the solids inside do not move.

Dad came back and tried it, and sure enough, it worked.

Through this incident, I not only discovered how to distinguish between raw and hard-boiled eggs, but also made me understand that everything in the world will be satisfying if you use your brain.

Discover ......There are many things in life that I am constantly discovering ......

Mom is a very clean person. Washing clothes is a "job" that she would rather not eat or sleep than do it, she puts her dirty clothes on the washboard, rubs them, rubs them, and does not always wipe the sweat on her forehead without foaming her hands and pounds her sore waist. The scene of my mother's laundry is like a scene in a movie, constantly "**".

Finally, one day, I took my dirty handkerchief and secretly washed it while my mother was not looking. After a great deal of effort, I finally washed the handkerchief, and I let out a sigh of relief. At this time, I noticed that my mother, who was already leaning against the door, had a relieved smile on her face.

My dad was very concerned about my studies and always knew how I was studying, but he never accompanied me or checked my homework. He always said, "I believe in children.

When I heard this, I had an inexplicable motivation in my spirit - I must study hard. I proved it all with my results. When I presented the red certificate to my father, I noticed that a bright smile appeared on my father's face, who didn't like to laugh.

My grandmother is over 70 years old, and she loves me very much, and when my aunt comes to visit her, she always brings a lot of delicious food, but my grandmother is always reluctant to eat it herself. She said, "Let my good granddaughter eat it, so that she can grow up."

I understand my grandmother's love for me. So I desperately submitted, and used the money to buy a bag of milk powder, and when I put the milk powder in front of my grandmother's eyes, I found that her already cloudy eyes flashed with tears.

The discovery made me see my mother's relief; Discovery made me understand my father's hope; Discovery, let me repay my grandmother's love. Discover ......

My findings.

Once, the teacher left us a special assignment - let us use waste items to make a work with scientific and technological content.

I thought about it and decided to "build a ship".When I got home, I found waste styrofoam for the hull, old toothpicks instead of steel nails, blue pen drawings for the windows, and small red flags made with labels for Arowana oil. Everything is in line with the principle of waste utilization. A catamaran passenger ship was finally made.

I happily lowered the boat into the pool, but to my displeasure it floated on the surface of the water but did not move. How can I make it go? I pondered for a while.

Suddenly, my eyes lit up. One day not long ago, I was using a few soap discs, and while the boat was playing in the tub, I suddenly noticed that one soap dispers was moving, and the others were floating there. Intrigued, I picked it up and saw a small bar of soap stuck underneath it.

I thought to myself: Could it be this little piece of soap that works? yes, why not give it a try?

I cut off a piece of soap with a knife and stuck it to the bottom of the boat, but I didn't see the boat move. Why doesn't it work. Oh, maybe it's stuck in the wrong place?

I readjusted a few times, but it still didn't move, and at this point, I was a little disheartened. I thought forget it. Just as I was about to give up, "I had to think about it for months, and ninety-nine times I was wrong, but the hundredth time I was right."

This famous quote of Albert Einstein rang in my ears for a long time. Yes! How can you do things halfway?

I pulled myself together again and tried it again, and finally I dug a groove under the waterline at the stern of the boat and glued a small piece of soap to it. When the boat is flooded again, wow! I saw it slowly drive straight ahead.

Looking at the boat, I muttered, "Why does soap make the boat move?" Heard by the father on the side, he patiently explained: "It's because the surface tension of the soap is greater than that of water." It dawned on me.

Through this experiment, I finally understood a truth: only by boldly trying can we succeed.

I've discovered the magic of tea.

One day, while peeling an apple, I accidentally cut my finger, and blood gushed out. I was stunned and saw a cup of tea on the coffee table, and I stuck my finger in it. Unexpectedly, the bleeding stopped after a while, and the wound didn't seem to be so painful.

I thought it was a psychological effect, and I didn't take it seriously.

Then one time, I fell on the balcony. The skin of the palm of the hand was scratched in one piece. With the mentality of giving it a try, I dipped my palms in the tea again.

Strangely, the bleeding stopped again! I told my classmates about it, and they also started treating the small bleeding wounds with tea. They also told me that the stronger the tea, the better.

We were all curious about this effect of tea, so we consulted the teacher. The teacher guided us to look up the materials. It turns out that tea contains a large amount of ampophylline, which can temporarily anesthetize nerve endings, so that the local pain nerves in the human body appear dormant for a short time and do not feel pain.

Alkali can also sterilize, prevent wound infection, dissolve surface or subcutaneous sediment, make full contact between wound broken muscles, ensure muscle growth, and speed up wound healing. If the temperature of the tea is low, it will also make the capillaries of the wound tense and constrict, which will have the effect of sealing the wound, and the bleeding will stop.

Don't underestimate a small cup of tea, it also has such a wonderful use!

My findings.

Everyone may discover some mystery of something, and there will be many experiences in the process of discovery, of course, even I, a person who does not like to discover, will discover the mystery of things, if you don't believe it, please listen carefully.

It was ...... on a hot and cool summer day

My sister and I were playing by the pond. Suddenly, a small red fish jumped out, a graceful dolphin-style diving action, with water droplets like a naughty child landed on the lotus leaf, rolled, turned over, and jumped up again, a flawless diving action was born.

I think that the lotus leaf must have been wet with water droplets, and the lotus leaf has no towel, so it is easy to catch a cold, and it can't take medicine. I dried it to give it a chance to sunbathe. So, I dragged the lotus leaves out of the pond with my own mopping floors.

Touch the lotus leaf with your hand, well, fluffy, and the texture is not bad. Take a closer look, huh? How did you do it?

I didn't believe it, so I put the lotus leaves in the pond and soaked for a while, and when I picked it up, it was still dry. Is it that the lotus leaf is too hot, and when it is hot, it will be thirsty; When you're thirsty, you want to drink water, so you swallow it, right? It must be like this.

I would like to see how lotus leaves can drink water without a mouth. So, I didn't care if the lotus leaf felt cold or not, and let it soak for a while. This time, I watched with excitement with wide eyes, and my heart was still beating "thump" from time to time, for fear of missing the scene where the water droplets were eaten by lotus leaves.

However, it backfired, and the water droplets were not eaten by the lotus leaves, but "bounced" into the water like marbles.

Why don't lotus leaves get wet? "I walked into the study with questions and opened '100,000 Whys'. A check, oh, it turned out that there was a nano film composed of nanometers on the surface of the lotus leaf.

The nano film is spread on the surface of the lotus leaf, making the lotus leaf smooth, as if putting on a waterproof coat for the lotus leaf.

I want to invent a book that is only four pages. This.
