Scientific knowledge manuscript 1
From the mysterious universe to everything around us, science is everywhere. What science will you write in your life? The following are three 500-word scientific compositions I compiled for you. If you like it, come and share it with me.
Scientific composition in life 1
newton
Found it when the apple landed.
law of universal gravitation
. When gas invented the steam engine, the bottle cap of boiling water was constantly jumped off by gas.
Archimedes
Found in the phenomenon of rising bath water.
Buoyancy theorem
In our life, science is everywhere. As long as you are good at discovering, you will understand that science is actually around us.
One day watching TV, I saw a motorcycle galloping on the inner wall of a circular barrel without falling off. I was attracted by this unique phenomenon, so I looked up the information and finally figured out its mystery: because when the car runs along the barrel wall, it will have a great centrifugal effect, and it is this centrifugal effect that pushes the car to the barrel wall, and the car can't fall off like it is attached to the barrel wall. Isn't that what we learned in physics?
centripetal force
Really? A small phenomenon contains great scientific knowledge, and what we have learned is only one tenth of the treasure house of life.
On my way to school, a small ant on the roadside caught my interest. It is climbing a 2-meter-high pole. Suddenly, the ant fell from a height of more than one meter. Just when I expressed my misfortune for the fate of this ant, it was still crawling on the ground unscathed! When I went home to check the information, there were also big articles. When an object moves in the air, it will be resisted by the air, and its resistance is in contact with the object and the air.
superficial area
Size is related. The smaller the surface area of an object, the greater the proportion of gravity, that is, the easier the resistance is to balance with gravity, so that it will not fall faster and faster. That is to say, tiny objects can fall at a small speed in the air, so ants will not fall to death when they land. So ants have so much knowledge!
Life is full of science. Let's explore every unique phenomenon with wise eyes, and we will gain success and joy!
Scientific knowledge manuscript II
I remember last summer vacation, my mother brought a few.
table tennis
Come back, we are competing to get table tennis. We throw table tennis on the ground like a pinball and let it bounce. Suddenly, the sound of "ga" attracted our attention. It turned out that my cousin's ball was accidentally crushed by him, and he immediately sat on the ground and began to cry. Mother put its ball in a bowl filled with boiling water. Slowly, the ball bulged. My cousin didn't want the wet ball, so he changed it with me. I asked my mother, "Mom, why did the flat ping-pong ball swell up in boiling water for a while?" Mom said, "That's the use.
Expand while it is hot
The principle is that the air in table tennis expands after being heated, and when the flat place is pushed up, the table tennis will be restored to its original state. "
One winter, I found another problem.
One night, when I took off my thick sweater to get ready for bed, I heard the crackling sound of my sweater and was very curious. I ran to ask my mother, "Mom, why does my sweater make noise when I take it off?" Mom said, "It may be static electricity. I have no idea. "
I'll get dressed right away and check the information. Oh, it turns out that this is electrostatic discharge caused by friction. When we wear sweaters during the day, our bodies and clothes are charged because of constant exercise and constant friction between sweaters and shirts, shirts and bodies. These positive and negative charges overlap and discharge, so we will hear a "click" sound. Ah, I see. It turns out that there are so many tips about science in life!
So we should explore bravely and acquire knowledge by ourselves.
