2020 Exploring Argumentative Writing Senior Three 1
After learning the article about the Dead Sea, I understand that some objects can produce great buoyancy and hold up heavy objects when dissolved in water. I'm curious: salt is common in every family, so can other spices in the kitchen have the same effect?
So, I went to the kitchen to find three seasonings, namely sugar, baking soda and salt.
I took out four glasses from the cupboard and filled them with the same amount of fresh water. Then I took out four eggs from the refrigerator. Add a spoonful of sugar, a spoonful of baking soda and a spoonful of salt to each of the three cups.
The experiment has begun! I stirred quickly to make these ingredients dissolve quickly. First, I put an egg in a glass with only fresh water, and I saw the egg sink directly. Then I put an egg in sugar water, baking soda water and salt water, but they all sank. I was depressed, so I asked my father: Why don't the eggs float?
Dad replied, "Maybe it's because of lack of concentration."
I listened and immediately added the second spoonful of sugar, salt and baking soda. ...
I put an egg in the sugar water, only to see it shake a few times and immediately sink to the bottom of the cup. I was about to cheer, but I didn't expect to be poured cold water. Dad seemed to see through my mind and said to me, "You haven't seen the back yet!" " "So, I put an egg in baking soda, and a miracle appeared! The eggs in it floated up slowly. I shouted with joy, "Oh, great!" "Then, I added an egg to the salt water, and the egg in the salt water slowly floated up. I am very happy that the experiment was successful!
I asked my father, "Why?" Dad smiled and replied: "Because they all contain an element called sodium, baking soda contains sodium bicarbonate, and salt contains sodium chloride, which may be because of sodium, so it can float."
I asked again, "Does everything containing sodium make eggs float?" Dad shook his head: "I don't know, maybe you can prove it by doing experiments when you grow up."

The discovery of countless new stars in the vast starry sky, the discovery of the American continent on the vast earth, the observation of the sun and rain, and the drawing of the human gene map should all be attributed to the unremitting exploration of mankind. There were ancients before, and there were newcomers after. Exploration goes hand in hand with mankind, starting together and ending together. It is the embodiment of human greatness and wisdom, and it is also the ladder of human progress.
Exploration has shown great value and played a great role in the scientific field. Archimedes cheered in the bathtub of exploration ―― the law of buoyancy was discovered, and Nobel cheered in the smoke of exploration ――TNT was successfully developed, Chen Jingrun took the crown jewel of science in a pile of exploration draft papers, and Yuan Longping won the reputation of "father of rice" in the field of exploration ... Throughout the ages, science and technology have pushed mankind from ignorance to wisdom, from barbarism to civilization, and exploration is the soul of scientific and technological development.
Exploration has also shown great strength in the field of literature and art and achieved fruitful results. Prose in Qin and Han Dynasties, poems in Tang and Song Dynasties, and novels in Ming and Qing Dynasties are all exploring China people's nirvana and self-renewal, building a beautiful landscape for the magnificent culture of the Chinese nation. Li Bai's "Wow, how can I solemnly bow and scrape to an official? No one will suffer from being exposed to an honest face", Su Shi's "I don't know the true face of Lushan Mountain, but toward which corner of the mountain", Zhu's "Ask where the canal is so clear, for there is flowing water from the source", Lin Zexu's "Standing on the wall without desire" and "Counting romantic figures also look at today.
Exploration also shows extraordinary power in the field of thought. Confucius' theory of "benevolence", Mencius' theory of "valuing the people over the monarch", advocated by Taoism, and said by Legalists, which system is not the great discovery of the sages in exploring social customs and human feelings; Marx's research on surplus value, his analysis of China's revolutionary situation, his theory of "one country, two systems" and Jiang Zemin's "Speech" are also the crystallization of wisdom contributed by human beings in exploration.
Exploration is as vast as the universe. Only by exploring can we not wander under the eaves of our predecessors and be trapped in the siege of our predecessors. We young people should learn an excellent skill, cultivate an indomitable spirit of exploration, explore in learning, innovate in exploration and show our talents in innovation! Explore with your hands, your heart and your brain!
Before leaving, let's listen to Qu Yuan's exhortation again: "The road is long, and it's Xiu Yuan, so I'll go up and down." Also remember Lu You's teaching: When "mountains and heavy waters are suspicious and there is no way", exploration will make you "another village with a bright future".

God always likes to play some modest jokes on people. When you overcome many difficulties and are ready to embrace victory, you suddenly find yourself back at the starting point. If you can face it calmly at this moment, you must have a belief-"the next apple is waiting for me!" "The road to scientific exploration is full of twists and turns, and the process of exploration is extremely difficult. Only those who have strong will, superhuman perseverance and broad mind can constantly improve in repeated failures and setbacks and finally succeed.
The story of Edison's invention of electric light is a good example. In order to find the material for filament, he did countless experiments. He used ordinary metal wire and many other materials, but all failed. Some people laugh at Edison because of this, thinking that he has done so many experiments and it is worthless at all. But he smiled indifferently and said: "The value of these experiments lies in telling future generations that these materials are not suitable for filament, which can prevent future generations from repeating failures. Isn't this a step closer to success? " Indeed, any exploration in life is essentially successful. This is not only true of scientific exploration, but also of everything.
Remember 1993 a place called Monte Carlo? Remember when Samaranch announced the results to the world? Remember when Australians cried with joy and hugged each other tightly? Remember the extreme disappointment of 65.438+0.2 billion China people at that time? An apple that was about to be picked suddenly fell down. Since 1993, when Beijing lost its bid for the Olympic Games to Sydney, China people still remember every detail, and we have to bear the blow of this failure. However, failure failed to cool China people's enthusiasm for bidding for the Olympic Games, and frustration failed to stop the exploration of the dragon's descendants. Facing up to failure, being brave in exploration and perseverance are the excellent qualities of the Chinese nation. The "Apple" who learned the right to host the 2000 Olympic Games did not belong to China people. They lifted a ladder and aimed at the "Apple" who hosted the 2008 Olympic Games.
We worked hard and improved ourselves, carrying the banner of "New Beijing, Great Olympics", and finally realized the dream of 200 1 to bid for the Olympic Games. Looking back yesterday, in 1993' s "Olympic bid of the century" activity, Sydney, Beijing and the Olympic Games belonging to all mankind actually won! After failure, we constantly reflect and explore, let us abandon impetuousness and pay too much attention to form, and move towards maturity. In the end, we not only won the right to host the 2008 Olympic Games, but also made the self-confidence of the Chinese nation unprecedentedly high and the cohesion of the Chinese nation unprecedentedly enhanced.
To sum up, we will inevitably encounter setbacks and failures in the pursuit and struggle, but setbacks have the value of setbacks, failures have the meaning of failure, and success ultimately belongs to those who make unremitting efforts to explore. I explore, so I succeed!

Everyone knows that I am a famous curious baby, and I like watching 100,000 Why. I found many scientific mysteries in the book: why do cats and dogs fight? Why do dolphins help drowning people? Why do eggs float in salt water?
Well, when I came home from school today, I couldn't help putting down my schoolbag and couldn't wait to do the experiment of floating eggs in salt water. I will prepare a packet of salt, two round eggs, a spoon, two glasses of water, a cup of hot water and a cup of cold water. Ready for all these experiments, I gently picked up an egg, carefully put it in a cold water cup, and then put another egg in a hot water cup, and two baby eggs waddled down. I stared at the two precious eggs, which were as motionless as "sleeping" in the water and didn't want to float at all. I was eclipsed.
Then, I added two spoonfuls of salt to two cups, stirred them with chopsticks, and stared at the eggs unblinkingly for fear of missing the opportunity. In an instant, a miracle really happened. The eggs in the hot water cup slowly floated up from the water, as if wearing an iron ring charm on their heads. Master Tang Yan said a spell, and the egg floated painfully. "Wow, it worked. It worked. The egg floated. " I clapped my hands and cheered.
After the excitement, another question appeared in my mind. I asked my father inexplicably, "Dad, why can the eggs in the hot water cup float after being salted, but not in the cold water cup?" Dad told me without thinking: "this is because hot water melts salt and turns it into salt water, which increases the buoyancy of water and makes eggs float." Cold water can't completely melt salt, and eggs can't float without buoyancy of water! "Oh, I see.
Science is really wonderful! If you are interested, please have a try!

"Hey? Why is this? " "Why is this?" ..... These are all words I often say, so I am often called "little question mark" by my parents. I especially like science and biology. I often read such books and look up all kinds of information on the Internet. However, I prefer to observe animals and plants directly, just like bees collect honey and butterflies collect powder. I am very interested in them.
In the corner of my yard, there is a big spider web. When we first moved to our new home, it was there. I begged my parents not to remove it. Anyway, he was the first to greet guests in his new home.
One Saturday afternoon, after I finished my homework, I went to visit my "old friend"-Black Spider as usual. Ah, look! A big fly with a green head stuck to the net. It struggled to break free from the net. The net shook violently with its struggle, but the more it struggled, the tighter it stuck. At this time, the spider casually crawled far on the internet, leisurely basking in its slender legs. After a while, the fly really has no strength to move. At this moment, the spider moved. It crawled over, spit a few filaments around the fly, bit it with its mouth a few times, then stepped back and rested again. I wait patiently, and then what will it do? In about five minutes. The spider crawled towards the fly, stuck it into the fly with a small thorn in its mouth, and seemed to be sucking greedily. Although I can't see its expression, I think it must be enjoying this delicious meal! Why can't even such a big fly break through such a fine spider web? Why don't spiders just bite their prey and eat it? ..... A series of questions surfaced in my mind, prompting me to look up relevant information online. It turns out that ordinary cobwebs can bear the weight of 500- 1000 grams. When they eat, they first inject their prey with a poisonous juice that can turn insect meat into water, and then suck it slowly. ...
Seeing this, I looked at my spider friend and thought: Nature is full of miracles. It turns out that such a small animal has such great wisdom. It has made me gain a wealth of knowledge and increased my interest in exploring this vast world.
