Introduction: This paper is divided into four parts. The first part is about the benefits of writing popular science compositions. The second part, how to write popular science composition; The third part, the display of students' works; The fourth part, how to choose popular science books for children. I hope it can inspire and help you!
The first article: the benefits of writing popular science compositions.
First, improve the writing level.
According to the survey, among 58 people in an experimental class, only 9 people are interested in textbook composition, accounting for15%; 58 people are interested in popular science composition, accounting for 100%. Interest leads to achievement. The good rate of popular science composition is above 85%, which is much higher than that of textbook composition. Recently, the teacher made a questionnaire survey for parents, and all the questionnaires were withdrawn, indicating that they were very happy, satisfied and in favor. Some people even think that this is a "new thing" and a "compulsory course for primary school students in 2 1 century". A student's mother said, "I can hardly imagine what a primary school student can write about popular science." I was shocked when I read "The Enlightenment of Fireflies" written by my daughter. It is not only clear in theme, but also very logical, and I am greatly inspired. "
Second, broaden the theme of writing.
Traditional writing is limited to humanities, such as writing people, taking notes, writing landscapes, writing objects and so on. Moreover, the use of common themes such as kindness and charity makes the composition lose its aura and vitality. The emergence of popular science composition has broken the unification of humanistic themes, and the scope of material selection has expanded from astronomy and geography to flowers, birds, fish and insects, covering the whole world, and there is no repetition from topic to content every time.
Third, active thinking ability.
Doubt is the starting point of thinking. Popular science composition begins with asking questions, which provides infinite space for the development of thinking. There are 100,000 whys, 1 million whys and 1 million whys in the universe. In the process of exploring these reasons, students will gradually develop the thinking quality of daring to question, criticize and create. According to statistics, in the process of popular science composition writing, 65,438+000% is consulting, 50% is consulting others (teachers, parents, relatives and friends), 32% is on-the-spot observation, and 38% is from experiments, which effectively promote the development of thinking ability.
Fourth, cultivate scientific spirit.
What is scientific spirit? In short, it is to love science, learn science and use science. Love is the premise, learning is the means, and use is the purpose. Improving the scientific quality of the Chinese nation is related to the rise and fall of China in the new century. It is urgent to popularize science from children. The practice of popular science composition has laid a solid foundation for cultivating students' scientific spirit.
The second part: How to write popular science composition.
The operation process of popular science composition is: asking questions-consulting materials-on-the-spot observation (or experiment)-writing articles. It can be summarized as the "four steps" of popular science composition.
Step one, ask questions. At the beginning of each semester, students observe reading and ask questions related to popular science as research topics. The more questions, the higher the quality, and the more sensitive the students' thinking tentacles; The broader the thinking space. Then publish these questions in the class for everyone to choose. You can choose one or two problems as your main goals in the near future.
The second step is to consult the information. Is to read with questions. This kind of reading is different from ordinary reading, with strong purpose and pertinence. In order to complete a popular science composition, most students go to bookstores and science museums to look up information, take notes, find answers and take pains to appreciate it.
The third step is field observation (or experiment). Observation can be divided into directional observation and opportunity observation. This refers to the directional observation used to explain a phenomenon. For example, some students found that there was a kind of colloid on the feet of Parthenocissus tricuspidata through observation, which revealed the secret of its "wall climbing ability". Some problems can't be solved by observation alone, but also by experiment. Of course, for primary school students, there are many scientific and technological problems, which are difficult to observe and inconvenient to experiment, and can only be solved by consulting materials. Such as "Is there water on Mercury?" "Dioxin-the devil that harms human health!" "Why are there stripes on the tiger?" Wait a minute.
The fourth step is to write a composition. This is the last step, the purpose, and it is carried out on the basis of fully possessing information. Its basic idea is to ask questions-analyze problems-solve problems. This article is written to reveal the process and results of analyzing problems.
The third part: Composition examples.
Battery regeneration
On Sunday, I listened to English on the repeater, but my voice became louder and louder. I looked up and there was no electricity. I just wanted to ask my mother for money to buy a battery, but then I thought, one battery, 1.5 yuan, four at a time, and the new battery was running out; In addition, abandoned batteries will pollute the environment ... by the way, I have read about the reuse of old batteries in books before. Why don't I try? So I went to the bookcase and rummaged through the books. At this time, my mother came over and asked, "Yang Yang, why don't you listen?" "Oh, the battery is dead." "Then buy two festivals!" "No, I want to make my own battery." My mother looked at me incredulously and said, "You are daydreaming!" "Just watch!" Finally, I found this book. According to the method introduced in the book, I found four old batteries, scissors and nails, and made some fertilizer from flower fertilizer. In order to persuade my mother, I specially asked her for help. First, I peel off the skins of the four batteries with small scissors (don't damage the prototype of the battery), then I use small nails to make holes in the battery surface, pour fat water into it, and then seal the holes with wax. So it's over. I put the battery in the repeater. Although there is electricity, the power is too small. I think there is probably too little fat and water. I did it again, but not yet. What's the problem? On second thought. My mother smiled and said, "I said no, you see, it failed!" " "I am not reconciled, thinking: the electricity for making batteries comes from fertilizer water. Can you exchange it for other raw materials?
Later I injected saline in the same way. The repeater was fully charged and took a long time. Mom saw it and said happily, "Haha, the battery factory is going to close down!" " "
It seems that waste is not necessarily useless!
The wet clothes are dry!
When I was a child, I often saw my mother hang wet clothes on the drying rack. After a while, mother took off the dry clothes from the clothes rack. I was curious and thought: Is there any magic in the clothes rack? Can wet clothes be hung up to dry? Later, with the growth of age and rich knowledge, I finally understood the mystery. The original water drop spirit hidden in clothes wanted to go to the outside world to play, so it slowly turned into wisps of steam and flew away hand in hand. So, the clothes are dry! In summer, the weather is very hot, and the elves are so hot that they shout, "Oh, it's so hot! How hot it is! Let's find a place to spend the summer, or we'll get heatstroke! " After that, they turned into steam and flew to the shade to enjoy the cool. In this way, the clothes will soon dry! Grandma Feng came, and the elves cheered: "Take Grandma Feng's car to play!" " "with these words, they spread their wings and flew to the journey of freedom ... so, the clothes soon dried up! Students, now, you should understand why wet clothes are dry! In fact, there are so many sciences around us, as long as you observe and think carefully, you can find them! With science, our life is more convenient and better!
Chapter four: How to help children choose popular science books.
Experts pointed out that choosing a suitable popular science book for children can start from the following aspects.
First, try to buy suitable popular science books according to your child's age. Due to the large age span of children, there are differences in literacy and understanding. Generally speaking, children (preschool children) are more sensitive to pictures than words, so they are more suitable for reading popular science books based on pictures. Students in the lower grades of primary school can start reading illustrated popular science books. Children in the middle and senior grades of primary schools can read popular science books mainly based on texts because of the improvement of literacy and understanding ability. Students in junior and senior high schools can choose more popular science books. Therefore, when publishing a book, publishers generally make different arrangements in terms of text depth, number of pictures, layout and so on according to different readers' levels. For example, the children's publishing house published a series of books entitled "100,000 Why", and developed a children's edition, a new century children's edition, and a new century pupil's edition. According to different age levels, they are provided to preschool classes, lower grades of primary schools, junior high schools and upper grades of primary schools.
Second, whether the form and content are suitable for children are two issues that must be considered when choosing books. The form of popular science books is often the first factor to grasp children's hearts, and the content determines the value of this book to children. Some parents, in order to make their children like reading, start with pictures and forms that children are interested in, but ignore the content and content of the book. As a result, the children read books, but their real knowledge did not increase much. And some parents, from the economic point of view, think that those text-intensive popular science books bring more things to their children, so they benefit a lot, but they don't take into account their reading psychology. Experts pointed out that those popular science books that combine form and content are worth choosing, such as Sanmao World Series and Knowledge Rubik's Cube Series, which have beautiful pictures, attract children, are rich in knowledge and are worth the money.
