also written a paper, the city has won the prize
washing powder I are familiar, but do you have a good study? Liang Yu, six of Cixi experimental primary school, made a series of experiments on washing powder, and wrote a paper with more than 3000 words and more than 10 charts, and won the two prize in the Ningbo Youth Science and technology innovation competition.
How did he think of doing this experiment? He has worked out how to make the washing powder more powerful. What kind of child is he? It can't help but curiosity.
his curiosity
How can we use it to make detergent more powerful?
How did you think of doing these experiments at that time? "One night, when I was in peace, I was doing my homework, and my mother was washing clothes on the side. I found that after washing the laundry powder, the dirty clothes were much cleaner. " Fang Liang, a 13 year old, thought it was interesting and planned to study it carefully.
he said he was very naughty, dressed in clean clothes to go to school every morning, but he went home and became a little kitten. There were various stains on his clothes. If you can think of a more powerful way to decontaminate detergent, mother can save a lot of work.
Fang Liang Yu first came to the supermarket with her mother and spent half a day studying various kinds of washing powder, washing liquid and soap, making a record and taking a lot of photos. The final decision was mainly on detergent, and there was a lot of enzyme detergent in the supermarket. Is it better to use enzyme laundry detergent to deal with stains? Is the washing powder cleaner with more clothes? By guessing, there is no answer. Fang Liang, who never washed clothes, began to experiment with facts and let facts speak.
in addition to different washing powder, he also prepared the same size cotton piece, paper cup, thermometer, chicken blood and other props. He explained: "in one experiment, there is only one variable so that it can be more accurate."
his experiment
he is most afraid of chickens. He faces chicken blood for two days, and makes a complete set of experiments,
what is the source of pollution? After comparison, Fang Liang Yu decided to use chicken blood. In fact, this bold boy is very afraid of chickens. "When I go to the market for chicken blood, I'm scared and pass the cup in the distance."
"does it go well?" "It's not going well. Take home, chicken blood solidified, how can not dye. Second days to go again, warm with hot water. " When
really did the experiment, Fang Liang Yu was distressed: "chicken blood is really disgusting, and it should also be rubbed and stirred." Would you like to change it to a simple point of ink? He refused. "My biggest feature is that things will be determined to insist on doing, the beginning can not end." So, the most afraid of his chicken blood for two days, finished the whole group of experiments, and got the conclusion of the several:
1. with enzyme detergent to deal with blood stains twice the result. In addition, it also has the same effect on sweat stains and oil stains.
2. when the water temperature is around 35 C, the washing effect of enzyme detergent is the best. If the temperature is too low or too high, it will affect the effect of washing powder.
3. washing powder with different concentrations has no significant effect on the washing effect of blood stains. The larger the concentration is, the better the washing effect is. But after too much concentration, the washing effect will not be very different. The shorter the residual time of
4., the easier it is to wash.
his paper
expert: experimental methods and conclusions have a scientific basis. After two days of experiment,
, Fang began to organize records, draw forms, write papers, and after repeated revisions, even adults feel annoyed, but he feels very interesting. "Yes. It's not boring at all. It's fun to write down the results of the experiment and answer the doubts at the beginning. The little guy said proudly.
Hu Minjie, director of the center for analysis and testing of Ningbo University of Technology, said affirmatively, "the methods and conclusions of this little friend are scientific and reliable."
the staff of Ningbo Association for science and technology told reporters that sometimes even a conclusion is incorrect for a child's thesis, which is also a good thesis. A pupil challenged a bee's voice by vibrating wings. He did a series of observation experiments and wrote a paper on "bees are not singing on wings." Finally, the conclusion was denied by the expert, but the thesis still won the prize in the national and world competitions. "Because the children love thinking, the spirit, the hands-on experiment ability is most valuable."
he's a man with a super big idea to show super good
"last year's tech innovation competition, his paper won the first prize." In the opinion of Wu Xucong, the instructor of the paper, Fang Liang Yu is very fond of science class. There will be many ideas and will be verified in various ways. This makes him different from a lot of students.
"super daring, super thinking, excellent performance before camera!" Zhong Xiaoyan, a teacher in charge of the class, almost used the 3 "super" to describe the student who had been teaching for 6 years. She gave an example: "whether it's a speech contest or a story competition, he will take part in it. Questions and answers in class are very personal. Many of the students came to stage fright on the Cixi TV station. He was very active. As long as he is there, there will be no cold. "

often, boys who prefer science and science will be weaker in the liberal arts section. "Fang Liang Yu" said: "Fang Liang Yu language" The text is very good, especially the composition. All the National Games have won the prize. It has a lot to do with family education. His parents are ordinary workers, and their cultural level is not very high. However, children are well guided, encouraged and supported to do experiments and participate in all kinds of activities.
after listening to the teacher's praise, Fang Liang Yu's mother was somewhat embarrassed: "he loved to read science books from childhood, and we bought a lot of back. The hands-on ability, in general. If he wants to do experiments, we are very supportive and help him with his ideas.
doing scientific experiments will affect children's performance. This is the concern of many parents. Perhaps Fang Liang Yu's "gorgeous" winning experience can refute this. In the past two years, he won the silver medal in the national original literature competition, the whole national silver prize for reading and writing competition, the first prize of the Ningbo Youth Science Carnival competition, and the three prize of the "Hope Cup" national mathematics invitational tournament.
the 13 year old boy told reporters: "when I grow up, I want to do things in science. I'd better study animals and plants." One of his favorite books is "the mystery of the world" bought three years ago. The mystery of the lake's monster and the mystery of Pyramid made him see many times. "Aunty," Sima Yi management "," Li Jiacheng learning "and" Li Jiacheng learn people "are also very good, recommended to you!"
