Essay on science Urgently needed

An interesting experiment.

Once, I was eating an egg when I suddenly had an idea: Can I write on the egg? So I hurried to ask my father as if I had discovered a new world

Dad, can you write in the egg? "Absolutely! Dad said suspiciously.

Can you teach me how to write? I asked ...... urgently

I excitedly ran to the kitchen to ......

I took out an egg, washed it, and then carefully dried it; Then he took a brush dipped in sour vinegar and wrote the word "Song" on the eggshell, and then put the egg in the air for a while, because according to Dad, he had to wait until the vinegar evaporated. I saw that the time was almost up, and put the eggs in the pot - boiling. A minute passed, and I took out the egg, "Hey, why isn't it cooked yet!"

Time flies! I reluctantly put it back in the pot. Two minutes, three minutes passed, and I couldn't wait to take out the eggs, "Haha, cooked!"

I smug myself to myself. The egg was put into cold water by me, waiting to cool, and I stared intently at the egg, the fruit of my labor. Fifty seconds passed, and I excitedly peeled the egg and looked at the white and smooth body, "Oh my God!

The song I wrote on the eggshell was actually printed on the egg. I said in surprise. However, this experiment still puzzled me.

Holding this unusual egg, I rushed into the study with doubts, turned on the computer ......It turns out that after acetic acid dissolves the eggshell, it can also dissolve a small amount of protein, and the protein has an amino acid group, which will be hydrolyzed under acidic conditions, showing blue or purple. "I see! It really made my mouth start!

From this experiment, I understand that in fact, in daily life, as long as we observe carefully, we will find many interesting things, and if we can put them into action, we can also gain more knowledge, wouldn't it kill two birds with one stone!

Everyone has a lot of strange and impressive things when they are young, and I remember when I was a child, my dream was to be a scientist, so I invented a game called "Engage in Research".

That day, my friend and I were on the balcony of our house, enjoying the scenery, and after a while, I remembered my dream of being a scientist, I followed the example of a scientist on TV, took a plastic cup, poured a little laundry detergent into it, and added a little incense ashes, and my friend saw that I was playing with these and started playing. Then, I picked up my plastic cup and walked into the toilet, I added a lot of water to the cup, and also added some various hand sanitizers, shampoos, shower gels--- I was tired, sitting on the chair looking at my practice, I couldn't help but touch it with my hand, "Wow! It's so hot" I screamed, my friend came over and touched it, and said it was very hot, I smelled it, and vomited!

We almost threw up, a very stinky smell of rotten eggs, we hurriedly threw away the plastic cup, and poured it on the orchid like a drug, thinking that tomorrow to see if the orchid would die, and so the day passed unconsciously.

Through this I found that I have an advantage, no matter what ideal I will always act, like my ideal now to be a **, I will play the game "Horse Riding and **" every day to learn to rule, looking for the feeling of being **, so I asked my dad to play more games for me, so I can be ** in the future, but I also have a shortcoming, my ideal is always changeable.

Later, I finally found out that the laundry detergent and shower gel would heat up and smell when mixed together! My feeling is that I do it better than action.

Hope it helps you, thanks.

1. Science in life.

2. Text We all know that there is science everywhere in life, and we can never do without science in life, and the science in life is really endless, and I have found a lot.

Once, I went to play table tennis with my friends in the ICBC courtyard, and I was playing, suddenly, I didn't catch it, the ball fell to the ground, I immediately went to pick up the ball, and as a result, I accidentally stepped on the ball, and we were very anxious, not knowing what to do. Eventually, I decided to go home and go to my mom to see if she could do anything. Mom said to soak the table tennis ball in hot water for a while, I did as my mother said, after a while, the table tennis ball gradually returned to its original state, we were very happy, but also very curious, I asked my mother what the principle is, my mother asked me to find the answer by myself, so we decided to check the Internet what the principle is.

I looked it up on the Internet to see how it works. It turns out that the table tennis ball itself is sealed, and the reason why it is flattened is because the pressure from the outside world is greater than the capacity it can bear, but it is not the same when soaked in hot water, because the table tennis ball will expand and contract, and the heat from the outside world is very large.

That's the science of life. In fact, there are many sciences in life, and the key lies in whether we explore and discover them. As long as we explore and discover the science in our lives, we will know more and more, more and more.
