The so-called "makers" are those who dare to think, innovate and fear authority. They don't always follow the rules, but dare to overthrow the routine life, like invention and creation, and are not afraid of fallacies. And our writing innovation interest class is just for these students who love invention and creation.
In my opinion, the real maker doesn't just stay in the lab all day and make a knowledgeable appearance, but can study some seemingly insignificant small problems in a monotonous life, so as to find the fun and sense of accomplishment of innovation. Innovation is not just a slogan, but a product of bold ideas and personal practice again and again. So, in fact, there are many makers around us!
Water Cut, Exploring the Secrets of Seed Growth, Steaming Ice ... In my spare time, I always do some small scientific experiments like this, and sometimes I write down my experimental steps and some feelings afterwards. I feel that I am not only doing experiments, but also being in close contact with nature and exploring the mysteries of science and innovation in the vast universe.
"Too superficial, I don't know anything." Of course, as a qualified maker, it is not enough to know a little written theoretical knowledge. You must create it yourself, so that you can understand the principles and mysteries. Last weekend, my classmates and I jointly designed a portable strong light small desk lamp. Although our knowledge is limited, its circuit is broken and it is easy to leak electricity, but this small desk lamp is the first product we designed together, and its significance is not light to us.
The first person who put forward this interesting idea was my deskmate in my interest class. She is usually a very thoughtful person who once designed a clay sundial herself. At that time, after hearing this idea, we were all very excited and immediately collected materials to implement it. Unfortunately, it's probably because we are too impatient. The result of our first experiment was not as exquisite as we thought: the cover of the desk lamp collapsed and the battery could not be connected.
However, we are not discouraged, but continue to experiment to preserve its advantages and avoid its disadvantages. Finally, we finally worked out a satisfactory plan. We made a simple bracket for the cover of the desk lamp, and then spliced it with various kinds of clay, so that it won't collapse in when it is used. As for the circuit problem, after puzzling, we asked the science teacher to help us plan. We are very satisfied with the result of this experiment. Although this desk lamp is still on and off, it is a precious treasure in our life.
After the design of the desk lamp, our respective innovative notes turned a new page full of brilliance. It seems that we can all see the bright light reflected by it, which is not only the light itself, but also the light full of our efforts and sweat, which is the light of our dreams!
My ideal is to be a scientist and invent many good things. Because scientists can always invent many good and strange things, I especially want to invent some. But I am so young that I will invent it when I grow up. But when I was a child, I would gradually cultivate my spirit of continuous exploration.
Actually, I still have many, many, many ideals. Such as painters, musicians, calligraphers and so on. But I can only do one task, because I don't have that much time, so I can only be a scientist.
When I become a scientist, I will first invent a time machine. This time machine can let you enter the human body, but be careful when entering other people's eyes. You'd better go in from the corner of your eye, otherwise it's not good to blind your eyes. You can also enter all parts of the world through the time machine, and you can go anywhere in just one minute.
I'm going to invent a laser gun, and there are endless bullets. If you meet an enemy, as long as you shoot, the enemy will go out immediately.
I also want to invent my own world, where the trees are very green. In winter, the grass is also green. There is still a lot of water there. Because there is little water on the earth, I must transport some water from my world to our earth.
I want to keep some Changjiang cakes as my pets. But Yang Zihua likes meat very much. What shall we do? Because I am a scientist, I invented some pills and let the Yangtze River eat them, and it will become a vegetarian. I also want to build countless ponds and keep my pets in them. I have other good things besides Yangtze cakes there! Such as reindeer, butch, dinosaur and so on. Dinosaurs are my favorites, such as Tyrannosaurus Rex, Liang Long and Stegosaurus ... because the world belongs to me and I like it very much. Of course, I also welcome my friends to visit my world. Will you come?
I remember on a Sunday morning, my sister and I played table tennis at home, and we had a good time. The ping-pong ball was dented because of excessive force. I looked at the sunken table tennis with a sad face and suddenly had a brainwave: can I change the sunken table tennis back to its original appearance? So, I took a ping-pong ball and asked my father.
"Dad, how can I restore the sunken table tennis to its original appearance?" I asked. Dad said, "put the ping-pong ball in the cup and then rinse it with boiling water." I did as my father said. When I rushed to the table tennis with boiling water, the depression of the table tennis slowly expanded and changed back to its original state. I asked happily, "Dad, why is it so amazing?" Dad smiled and said, "It's not magic, it's because of the principle that heat expands and cold contracts. Thermal expansion and cold contraction are the basic properties of objects. Generally speaking, an object will expand when heated and contract when cooled. All objects have this property. "So that's it! I didn't expect such a big mystery. "
From this experiment, I understand: in fact, in our daily life, as long as we observe attentively, we will find more interesting things, stimulate our greater thirst for knowledge and explore higher scientific knowledge and mysteries.
On Sunday, I was reading a science book. Suddenly, I was fascinated by a scientific experiment. Draw a hole with the size of fifty cents on the paper, and a one-dollar coin can pass through it. How is that possible? A dollar coin is smaller than a dime and will not pass, but can it be proved by experiments?
The experiment began. First, I prepared a one-dollar coin and a fifty-cent coin. I first drew a hole the size of a dime on the paper. Next, I am confused. How can I let the coins pass? Straight through? Give it a try! As a result, the paper broke and the first experiment failed. But nothing is difficult in the world. As long as you are willing to climb, nothing in the world can be successful at once! I decided to do it again.
The second experiment began. This time, I think it over. Suddenly, I had a brainwave. I found that the paper was squeezed into the middle and formed an oval shape. So that coins can pass through? My experiment is really like this, and I finally succeeded!
Through this experiment, I know that everything can't be easily believed and needs to be proved by experiments, so I can't draw a conclusion easily. We should constantly seek the unknown in the known to get more things.

After work in the evening, Helen the robot brought hot coffee. "What TV program do you want to watch?" "Well, Phoenix Information!" As soon as she pointed to the wall, the host was projected in front of us.
Helen opened the electronic menu. "Let's eat braised pork rice and hot and sour soup. I'm going to the movies after dinner. " "Wait a minute, dinner will be ready in three minutes." Helen said, "The movie tickets have been booked for you. The underground capsule system is under maintenance. The outdoor temperature is 20 degrees, and the air quality is excellent. It is recommended to travel by bike. It is estimated that 15 minutes will arrive at the destination! "
The cinema is as big as a basketball court. Just then, black music began, and a huge snow mountain rose in the middle of the cinema. Heavy snow, chill, snow-capped mountains shining silver. At the foot of the mountain is a colorful grassland. Suddenly, a group of Tibetan antelopes flew over the horizon, thousands of them, all dark and unstoppable, passing by the audience.
There was a loud noise, and the huge flying saucer hit the snowy mountain. In an instant, huge stones and flames hit the audience like an avalanche. I broke out in a cold sweat and exclaimed ...
"Hey, it's time to get up. At 9 o'clock, there is a speech about the city at the city hall! " Helen is my artificial intelligence secretary. Her face is pure, her eyes are deep, and her white coat and light blue jeans exude youth and skill. This is the artificial intelligence that our institute is testing. It looks like a real person and has the intelligence of an ordinary adult.
Looking out the window, it's a beautiful day. The whole city is lush and quiet, with only pedestrians and bicycles in twos and threes. Streets and communities are as beautiful as gardens. Urban air and ground have long been controlled, and citizens choose urban underground capsule system to travel.
Every family has one or two "city capsules". Using magnetic levitation technology and vacuum pipes, you can connect to the city's "cloud" intelligent system and tell your destination. No need to drive, no pollution, no noise, safe and free, and the longest time in the urban area is no more than 2 minutes!
Good morning, leaders and elites of cities! The theme of my speech today is that when the city has the wings of science, our future is no longer imagination. ...
Sixth grade scientific composition for 6 days! How can four small cylindrical paper tubes bear the weight of more than ten kilograms? But it really can. In Chinese class today, our group did this seemingly incredible experiment.
The experiment is simple. First, I took out a piece of A4 paper, divided it into four parts on average, and made four paper tubes with the same size from each rectangular piece of paper. Then everyone sticks the paper tubes one by one and makes them stand upright on the table. At this time, everyone is already eager to try. I had an epiphany and flew out a series of books on Chinese subjects. Everyone took out their books one after another, and the experiment began! I carefully put the book on four paper tubes, hey! Steady! Then everyone put the books one by one, five ... ten ... fifteen ... twenty ... Oh, my God! There are more and more books. I opened my mouth and looked at the small column below. I didn't even want to fall. Our experiment attracted students' dumbfounded expressions, but there seems to be 100 books in the following column, and the teacher was also amused by our group's experiment. The number of books has increased to thirty, and my mood is even more tense. How many books can I put? When will it fall? Too late to think about it, "pa!" The pillar fell down. Everybody count the books, forty-five books! I remember that when moving books, it took two male students to move forty books. It's not easy to move small pillars! When I got home, I weighed myself. A book weighs about 400 grams, which means that the small paper tube bears the weight of 18 kg!
But why can a small paper tube bear such a heavy weight? It turns out that the side of the paper tube is curved and the curved surface is arched. When the arch is compressed, it will resist the force from the arch column and transfer the force to the adjacent parts, so it can bear greater pressure. It turns out that the small paper tube has done so many things invisibly!
In fact, science is everywhere. As long as we observe carefully and think seriously with the eyes of discovering science, maybe you will become a scientist admired by thousands of people in Qian Qian in the future!
Have you tried science in your life? Maybe not, but I did it. Come and have a look!
I found this experiment on TV by accident. In wartime, in order to send information safely without being discovered by the enemy, intelligence workers used a method called "writing secret letters". Seeing this, I am curious. Why can't we see the written words? Better, let me make a scientific attempt!
I took out a science and technology book and found the steps to do the experiment. I dipped some white vinegar with a clean brush, then spread a piece of white paper on the table and wrote a poem on the paper with a brush. The words are dry, and there are no traces of words on the white paper. Then dip a clean brush in the carrot liquid and evenly spread it on the white paper, and the words will appear.
What is the principle? I checked the computer, and the computer showed that the secret of white vinegar secret letter was the natural pigment of carrot. As long as carrot juice is coated on an acid-containing object, it will appear on white paper. I'm especially glad I found the answer.
"It is more valuable to explore the truth than to have it." Einstein said this sentence is really a famous saying. As long as you are a conscientious person in life, have a keen heart and a pair of observant eyes, you can discover scientific mysteries that you never knew.
