This little thing aroused my infinite thinking. Why do several friends say they don't know such a common plant? Maybe this is the blindness in life! After careful reflection, I think the reason for this phenomenon is that there is no habit of careful observation in life! It seems that careful observation is a valuable quality! You see, there are so many great inventions in history (Lu Ban invented the saw, the Wright brothers invented the plane, Archer invented the story of stamp perforation, and Watt invented the steam engine ...), which one can't do without careful observation of familiar things around him and serious thinking? It can be seen that observation and thinking are not only an act, but also a kind of consciousness, an attitude and a habit. This incident made me as a teacher, especially as a science teacher, re-examine my teaching philosophy. Personally, I think that scientific inquiry activities should be really carried out in primary school science classes, so as to cultivate primary school students' scientific literacy. Training them to really learn to observe and really learn to think is the premise.
How can we cultivate children and make observation and thinking a living habit? We try to explore in teaching:
First, stimulate the interest in learning, observing and thinking before class.
When scientists do science, they are first curious about things, which leads to a series of problems, and then apply the scientific process to these problems cautiously and appropriately. Of course, our science class can't expect children to study scientific problems like scientists, but during the whole learning process, they can know how scientists think and work, and they can also explore their own problems in a way similar to that of scientists.
(1) Carefully choose the topic of study and observation before class.
For example, last winter vacation, the school's moral education office arranged an assignment to carry out a scientific and technological activity. I will combine the theme of life education to let children observe and explore the whole process of hen hatching chicks. (Because there is this part in the fourth grade textbook "Freshness", and it is also in the third grade unit "Animal Life Cycle")
(2) Carefully guide and observe before class.
My approach is: first, introduce the whole process of hen hatching chicks to children, which takes about 22 days, so that children can find the relevant information of hen hatching chicks online. Then let the children go out in groups to observe the event. Our school is in the countryside, so it is easier to find information and carry out this activity. The teacher came forward and hired a student's parents as the activity instructor, so that the activities could be carried out directly in the students' homes. I asked the students to design their own observation records, and let them observe the process of hen turning eggs, hen eating and the daily change of eggshell color every day. And every few days, record the observed object with a camera. ) On the 2nd1day, a chick is trying to peck through the eggshell, and a new life is about to be born. The children's desire for observation boiled at once. How dedicated and curious their little eyes are! During the activity, the mother of Zhang Yujie, a student in Class 40 1 class, said excitedly, "Great. At 6: 42 pm, the first chicken pecked its shell, and my daughter squatted beside the chicken nest for a whole hour. She forgot dinner, and she gave birth to a new life with her tender little hands. " Enter it into the computer immediately after filming, even if you sit down and write an observation diary. I was really moved by her that day. "What a good observation practice process before class. The children went through this process wholeheartedly, during which they observed and thought about the birth and preciousness of life. The motivation of this observation comes from the teacher's interest in children's observation and thinking before class.
Activities of the same nature-observing the life of silkworm babies. We are organizing students to carry out group activities.
(3) accumulation and arrangement after observation and thinking.
After the activities like the above are carried out, I will ask the students to organize the activity records and photos in time and write an observation diary carefully. These can be displayed on the classroom "booth", and when this part of the content class is attended, these will become valuable teaching materials. Because it comes from students' personal life experience!
I think, as long as our teacher can pay more attention everywhere, be good at stimulating students' desire to observe and think before class, and cultivate the habit of observation for a long time in life. If the above activities are carried out several times, then in the teaching process, the study of scientific knowledge, the development of inquiry activities and the cultivation of emotional attitudes and values will certainly achieve natural results in classroom inquiry activities.
During the activity, I felt the happiness as a science teacher, and also gained the sense of accomplishment as a science teacher-cultivating future scientists. They should be taught that they have taken the first step in scientific exploration and research. At this time, Darwin's philosophical words came to my mind again: "I have no outstanding understanding or extraordinary wit, but I only perceive those fleeting things and observe them carefully." Obviously, observation before class is very important. What's more, our training object-students!
Second, create observation and thinking situations in inquiry activities.
The purpose of real scientific research is to describe and explain the world, and the way to describe and explain the world is observation and experiment. In fact, experiments can be regarded as indirect observation by means of instruments or manual observation, so observation is the basis of any scientific research. "Zhejiang Primary School Subject Teaching Suggestion Science" also tells us: "The main learning methods of primary school science are observation and experiment, and students can acquire knowledge, cultivate interest and scientific attitude through personal inquiry." Observation is a common form of scientific inquiry in our primary school teaching. Its purpose is to discover the substantive laws contained in things, not superficial phenomena, and it is the main means of scientific learning.
Some time ago, I was lucky enough to enjoy the lesson "How Sound is Generated" that Zhejiang special-grade teachers showed us. At the beginning of the class, Chen Te slowly touched the treasure in his pocket, but he couldn't touch it for a long time. I was anxious to sit down and listen to the class, and a curious desire immediately arose-what was it? I looked at Chen Te's hand and pricked up my ears to listen to Chen Te's every slow word. For a long time, he took out an ordinary steel ruler from his pocket and put one end of the ruler on the table. Said, "Is there any way to make this ruler make a sound?" That's the simple opening remarks. Let's wait, observe and think carefully. At this time, I noticed that all the students and all the science teachers attending the meeting were staring at the steel ruler in Chen Te's hand and thinking about Chen Te's question-"Is there any way to make this ruler make a sound?" A few seconds later, a classmate raised his hand and said, "Press hard and let the ruler make a sound." Chen nodded, affirming that the student had his own ideas, and asked him to sit down. Turn around and write the word "difficult" on the blackboard. "Can hard work really make the steel ruler make a sound?" This is Chen Te's second inspiring words. I saw that his left hand pressed one end of the steel rule, and his right hand pressed the other end of the steel rule hard until it was bent to a certain angle. Then gently and slowly reset one end of the steel rule. (At this time, there was silence in the classroom, and everyone listened attentively. ) Chen Te asked again, "Did you hear the sound?" "No" students answered in chorus. Under the careful design of teacher Chen Te, a scientific inquiry activity made all the children and our teachers devote themselves to careful observation and serious thinking. And in the process of exploration, the practice proves that the idea of the first classmate (pressing hard can make the ruler make a sound) is wrong. So how can we make the steel rule make a sound? Therefore, students naturally transition to the observation and thinking of the second inquiry activity. ..... in-depth, keep asking questions, guide students to keep observing and thinking, and explore in an orderly way that sound is produced by vibration. Chen Te's class is like a trickle in the classroom. What flows to children and our hearts is a valuable spirit of scientific inquiry-making observation and thinking a living habit. In this class, you can see that Chen Te did not use any gorgeous courseware, but created a scene of observation and thinking for students' inquiry activities without trace. He designed it purposefully, planned and hierarchically, raised questions related to the teaching content, stimulated students' enthusiasm for knowledge, and introduced students into a scene related to the questions. In the problem scenario, give students enough time and space to imagine freely, and encourage students to see, listen, think and discuss more while igniting their thinking sparks. Let students go through the process of scientific inquiry, from which they can easily learn scientific knowledge and sublimate their emotions. After listening to the class, I chewed the realm of this class carefully, which was quite intriguing. This realm is worth my constant thinking and learning.
Third, pay attention to the observation and thinking after the inquiry activity.
Five years of teaching knowledge and five years of teaching experience in science have given me a lot of thinking and accumulated some teaching experience. I recall the teaching methods of natural courses I studied in Huzhou Normal University, the teaching experience of common sense courses in Gao Yu Primary School and the teaching experience of science courses in Liangpeng Primary School. My teaching experience seems to coincide with the process of curriculum reform. In this process, the teaching materials are constantly changing, and my teaching philosophy is also updated in repeated training and listening to wonderful lectures by teachers Yuan and Ye. I don't think inquiry activities should start in the classroom and end in the classroom. Instead, we should pay more attention to observation and thinking after inquiry activities while stimulating the interest in learning observation and thinking before class. Isn't Anji county holding a youth science and technology competition every year? I think if we can pay more attention to students' observation and thinking after the classroom inquiry activities, then students will be interested in small inventions and writing small papers in the competition. Interest is the best teacher, and we will have no strength to coach. I tried to guide students in this way a few years ago, and I did achieve some results.
"Observe, observe and observe again" is a famous sentence inscribed by Pavlov, a world-famous physiologist, on the stone tablet at the entrance of his institute to emphasize the importance of observation for research work. I keep this famous saying in mind, which guides my teaching thought and spurs my teaching behavior. Strive to train my students to really learn to observe, really learn to think and really learn to explore. Let observation and thinking coexist with inquiry learning, and let observation and thinking become a living habit.
Observing life and thinking about life, are you still worried about the heat in summer? Are you still sad about the fallen leaves in autumn? Are you still afraid of cold in winter? Friends, don't be sad, don't be impatient, as long as you observe carefully in your life, you will find that Miss Chun has quietly come to our side.
Happy people in spring
You see, the streets and roadsides are full of busy and happy people, especially dazzling in the sun. At this time, Miss Chun soon planted the seeds of happiness in people's hearts. In the field, children are flying kites happily. The design of the kite is a beautiful fairy. From a distance, it seems that Miss Chun is greeting everyone. The seeds of happiness grow fast! At school, a group of lively little girls are jumping rubber bands, and even boys are eager to try, not to mention how happy they are! "Apple trees …" When they beat, the seeds of happiness in everyone's heart are quietly growing, ah! Look, the seed has grown into a happy tree full of fruits!
Floating flowers in spring
Walking on the country road, I can't help but feel relaxed and happy when I look at the beautiful scenery of "a bright future, rain and snow". Suddenly, my eyes were attracted by what I saw. A small flower growing on a hillside stubbornly endured the wind and rain. Although this unknown flower was hit by the strong wind, it still didn't bow its head or give in. Its body is weak, but its life is tenacious. I was deeply shocked, and Bing Xin's poem rang in my ear: the flower of success, people are only surprised by its current brilliance, but its bud is saturated with the source of struggle and full of blood and rain of sacrifice. I suddenly realized that perhaps the reason why flowers are so unyielding is because they want to bloom their most gorgeous colors in spring! With respect for Xiaohua, I continued to walk on the path and watched the spring rain fall on the ground. I remembered an ancient poem: the rain in the sky is crisp and crisp, but the grass color in the distance is close at hand. I looked at the ground absently, only to find a grass trying to stretch its waist. "Wildfires can't be blown out, they grow taller in the spring breeze." Grass is common, common. Knowing that you can't be a towering tree, you made a grass, adding a touch of vitality, a green landscape and a green force to spring. Miss Chun's green skirt was given to her by the grass! The light rain in the mountain village gradually stopped and Grandfather Sun came out. Sister Rainbow will also come to play with Miss Chun. Flowers and grass stand up straight and accept the sunshine after success!
In my life, I found many interesting things and many beautiful people. Friend, it's spring. Have you noticed it in your life?
Write about things in life, observe and think, such as what you see in life and what you think afterwards. You always have your own opinions and judgments about everything you see in life. Or you can get valuable writing content from other people's expressions and language.
Find the theme you want to express and write your own understanding around it.
An ant is an insect. It belongs to Arthropoda, Insecta, Hymenoptera and Formicidae. There are many kinds of ants, including 1 1700 species in the world and 283 genera of 2 1 subfamily. More than 600 species have been identified in China. Recently, a new ant was discovered that reproduces asexually. Ants live a long life. Worker ants can live for a few weeks to 3- 10 years, while queens can live for more than ten years or decades, or even 100 years. An ant nest can grow from 1 to 1 in 1 places.
Ants are typical social groups. There are three social factors: individuals of the same species can cooperate with each other to take care of their larvae; There is a clear division of labor; At least two generations in the ant colony overlap (individual cases are not excluded), and future generations can take care of the previous generation for a period of time.
Ants are definitely experts in architecture. There are many compartments in the nest, and these compartments have their own uses. Among them, the queen ant has the largest compartment. There is an ant in the desert, whose nest looks like a castle from a distance, 4.5 meters high. When those nests are abandoned, they will be used by some animals as their own nests. The bottom of the nest is for the queen. The queen's task is to eat, mate and have children. The ant nest is solid, safe and comfortable, and the roads extend in all directions. There is also a circle of soil outside the ant nest, and there are some places to store food. Ventilation is cool, warm in winter and cool in summer, and food is not easy to deteriorate.
Ants are also famous architects in the animal world. They dig holes in the ground with their jaws and carry sand grain by grain to build their nests. The "room" of the bird's nest will keep its original shape unless the soil is seriously dry. Walter Chilgel, an expert in ant research, modeled the ant nest. He poured liquid metal, paraffin wax or orthodontic gypsum into the ant nest, solidified it and dug it out. He said, "You can get a structure that goes deep underground." According to his observation, the area closest to the surface has the most ant rooms, and the deeper the ant rooms are, the smaller the area is. He said: "In order to do this, ants must know their depth relative to the ground." But how they are "constructed" is still a mystery. According to Chilger, ants can measure the depth by sensing the carbon dioxide content in the soil.
Observe the bug's life, fly over the sea, fly over the sea, fly over the sea and the wide consequences and the wide consequences immediately restore the concierge; Just do it; Underground dry big dress admire the admiration of the plane. Oh, the green light goes through the generator tree
Observation experiment composition in life This afternoon, when Teacher Liu taught me to write a composition, she told me a secret. Teacher Liu
He said, "Take a cup and a piece of paper." Hearing this, Weicheng Pan immediately said, "Yes! Yes! I have also done this wonderful experiment. " Then Teacher Liu told me how to do this experiment. After listening, I can't wait to go home and do this experiment.
When I got home, I hurried to find something to do the experiment. I found a paper cup and a paper cover. Then I pour water into the paper cup, put the paper cover on the cup, and then I loosen the paper cover in turn. At this time, the water didn't overflow, but it usually flowed downwards. I haven't seen this situation yet. I immediately had a lot of questions in my heart. With my mother's permission, I went online to Baidu to find the answer. It turned out that the reason why the water didn't spill down was because I was worried about air compression. Now, I finally understand.
My mother told me, "If you look closely, you will find incredible things." After listening to my mother's words, I understand a truth: observation is very important, and only observation can lead to more discoveries.
In addition to the intense and fulfilling study life, I also have a relaxed and happy holiday life. That colorful content enriched my life, and also added some fun and leisure to my naive student life.
Going for a walk after drinking tea is my daily compulsory course. Walking among the flowers and plants in the community, breathing the fragrant air, keeping company with flowers and birds, enjoying the richness of roses, the nobility of lilies, the strangeness of dinner flowers, the beauty of magnolia and canna, I will gently say to myself, "Life is really beautiful." I sincerely feel the five people around me.
Observation of life and reflection on family style, 500 words early in the morning, we all set off for the seaside. We took many photos on the road. We arrived at the hotel at noon. After having lunch there, we went to the beach. We were so tired that we lay on the beach all afternoon and swam a lot. On the way back to the hotel, we went to buy presents. It rained at night. We all stayed in the hotel and played table tennis. We had a good time today.

How to write a composition about observing life? Life is the main source of students' practice, and observation is the main way for students to write a good composition. For the external information in life, it is necessary to observe it before it can enter the human brain. Only those who love life and are good at observing life can find writable materials from life and events around them, and they can't help but have a strong desire to write.
