Through experiments and analysis of examples, the students 'ability to observe, analyze, and summarize was cultivated. 2. Guide students to use what they have learned to explain practical problems related to energy conversion and transmission, and improve students 'knowledge transfer and application ability. ###(3) Emotions, attitudes, values, goals 1. It would allow students to experience the commonality of energy conversion and transmission in daily life and nature, and stimulate students 'curiosity and desire to explore physical phenomena. 2. Through group cooperation and exploration activities, students 'teamwork and communication skills are cultivated. ##2. Difficulties in Teaching ###(1) Teaching Focus 1. Grasp the principle of mutual transformation and transmission between different forms of energy. 2. Understand the law of the total amount of energy in the process of energy conversion and transmission. ###(2) Difficulties in Teaching 1. How to guide students to abstract general concepts and laws from specific examples of energy conversion and transmission. 2. Using the law of conservation of energy to analyze complex energy transformation and transmission phenomena. ##3. Teaching Method Teaching method, experimental inquiry method, discussion method, case analysis method ##4. Teaching preparation 1. teacher preparation - Create a multi-media course that includes examples of energy conversion and transfer, such as electric light (electric energy converted into light energy and internal energy), car driving (chemical energy converted into mechanical energy, etc.). - Prepare demonstration equipment, such as batteries, wires, small light bulbs, small electric motor, small fans, etc., to demonstrate the conversion of energy. - Prepare daily items related to energy conversion and transmission, such as lighters (chemical energy is converted into internal energy and light energy), solar lamps (solar energy is converted into electrical energy and then converted into light energy), etc. 2. Students, get ready in groups. - Each group prepared some simple experimental materials, such as rubber bands (elastic potential energy related experiments), sandpaper (mechanical energy converted to internal energy), etc. ##5. Teaching process ###(1) Introduction to the new lesson (5 minutes) 1. By playing a video that contained a variety of energy conversion and transmission phenomena, such as waterfalls (mechanical energy conversion), electric lighting, thermal power generation, etc., the students were guided to observe and think about the forms of energy involved in the video and whether there was any connection between these energies. 2. Ask the question: What other similar phenomena are there in our daily lives? What kind of scientific principles were hidden behind these phenomena? This led to the main topic of this lesson-the transformation and transmission of energy. ###(2) New lesson (25 minutes) 1. Form of Energy (3 minutes) - Explain the main forms of energy, including mechanical energy (kinetic energy and potential energy), internal energy, light energy, electric energy, chemical energy, nuclear energy, etc., and briefly explain the embodiment of each form of energy in life, such as moving cars have kinetic energy (mechanical energy), hot water has internal energy, and the light emitted by the sun has light energy. 2. Energy Conversion (12 minutes) - The teacher demonstrated the experiment: - The students were guided to analyze the energy conversion in this process, that is, the chemical energy of the battery was converted into electrical energy, and the electrical energy was converted into the light energy and internal energy of the small light bulb. - The battery was connected to a small motor, and when the small motor started to rotate, it would drive the small fan to rotate. The process of converting chemical energy into electrical energy and electrical energy into mechanical energy was analyzed. - The students were divided into groups to conduct a simple experiment: - Let the students stretch the rubber band and then let go. Observe the process of the elastic potential energy of the rubber band transforming into kinetic energy. - Rub the metal rod with sandpaper and feel the conversion of mechanical energy into internal energy (you can feel it by touching the metal rod to heat it up). - Lead the students to discuss and conclude that under certain conditions, different forms of energy can be converted into each other. Ask the students to list more examples of energy conversion in life, such as burning coal (chemical energy is converted into internal energy), solar water heater (solar energy is converted into internal energy), etc. 3. Energy Transfer (8 minutes) - Using heat transfer as an example, he explained the concept of energy transfer. For example, if a cup of hot water was placed into cold water, the internal energy of the hot water would be transferred to the cold water, causing the temperature of the cold water to increase and the temperature of the hot water to decrease. - Demonstrate the working process of the small solar lamp. It shows that solar energy is first converted into electricity, and the electricity is transmitted to the light bulb through the circuit. The light bulb then transforms the electricity into light energy. In this process, there is both energy conversion and energy transmission. - Let the students think about and discuss other examples of energy transfer in life, such as using an induction cooker to heat a pot (electric energy is transferred to the pot, so that the internal energy of the pot increases). - To summarize the characteristics of energy transfer, such as energy transfer from high-temperature objects to low-temperature objects (the direction of heat transfer), or from objects with more energy to objects with less energy (the trend of other forms of energy transfer, etc.). ###(3) Law of Conservation of Energy (10 minutes) 1. The question was, during the process of energy conversion and transmission, would the total amount of energy change? 2. The teacher demonstrated the process of energy conversion and transmission through the multi-media class, such as the conversion of gravitational potential energy into kinetic energy of an object falling from a high place. The total amount of energy remained unchanged throughout the entire process. 3. Explain the content of the law of conservation of energy: Energy will not be destroyed out of thin air, nor will it be produced out of thin air. It will only be transformed from one form into another form, or transferred from one object to another. During the process of transformation and transfer, the total amount of energy remains unchanged. 4. Let the students divide into groups to discuss and list examples of energy conservation in life. For example, when a person rides a bicycle uphill, the person consumes chemical energy. Part of it is converted into mechanical energy for the bicycle and the person, and part of it is converted into internal energy (overcoming friction to do work), but the total energy is conservative. 5. Students were guided to think about the importance of the law of conservation of energy in modern science and technology and social development, such as the rational use of energy and the development of new energy sources. ###(4) Class summary (3 minutes) 1. Guide the students to review the main content of this lesson, including the existence form of energy, the transformation of energy, the transmission of energy, and the law of conservation of energy. 2. It emphasized the commonality of energy transformation and transmission in daily life and nature, and encouraged students to continue observing and thinking about the energy phenomena around them after class. ###(5) Class Practice (2 minutes) Give some simple exercises on energy conversion and transmission, such as pointing out the energy conversion in the following phenomena: (1) drilling wood to make fire;(2) electric lights shining;(3) the water turbine in the water power station drives the generator to generate electricity. Ask the students to answer quickly in class to consolidate what they have learned. ##6. Reflection on Teaching 1. the key of success - Through the combination of various teaching methods, such as demonstration experiments, group experiments, discussion methods, etc., students were more involved and could better understand the concept of energy conversion and transmission as well as the law of conservation of energy. During the teaching process, the students thought actively and could list many examples from life, indicating that their ability to master and transfer knowledge had been well cultivated. - In the design of the teaching process, from the introduction to the new lesson, to the summary of the class and practice, it progressed step by step, in line with the students 'cognitive laws. The imported videos could attract the students 'attention and stimulate their interest in learning, while the classroom exercises could consolidate the knowledge that the students had learned in time. 2. deficiencies in - During the analysis of energy conversion and transfer examples, some students might not have a deep understanding of some more complicated phenomena. For example, in the examples involving multiple energy conversion processes, such as the working process of a car engine (chemical energy is converted into internal energy, internal energy is converted into mechanical energy, and some energy is converted into other forms of energy such as electricity), some students were confused. In the future, he could add more analysis and explanation of such complex examples, or use more intuitive animation to help students understand. - In the group experiment, although the students could carry out the experiment and draw conclusions, the division of labor in some groups was not clear enough, resulting in low efficiency. In the future, students needed to be trained in group cooperation in advance to clarify the responsibilities of each member and improve the efficiency of group cooperation. 3. improvement measure - For the understanding of complex energy conversion examples, more detailed animations or multi-media coursewares could be created to break down the complex process into multiple simple steps for demonstration. At the same time, students could be guided to gradually analyze the energy conversion and transmission in each step. - In terms of group cooperation, not only did they have to clarify the tasks of each student before the experiment, but they also had to explain the process and requirements of group cooperation in detail. They also had to strengthen their inspection and guidance during the group experiment to find problems and solve them in time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Some of the plots in the novel involved the father heartlessly throwing the child down the building. For example, in the president's heart-wrenching novel," You're a Wound in My Heart," the husband of a high-ranking official on the tenth floor threw the child out of the window with his own hands, and then the female protagonist resolutely jumped down. In reality, there were also some tragic incidents similar to fathers hurting their children, but this was fundamentally different from the heart-wrenching plots in novels. The novels often used extreme plots to shape characters, promote the development of the plot, and trigger the reader's emotional resonance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Ren Jialun rarely participated in variety shows. His " On Phoenix Stage " would enter a variety show as a semi-resident after filming next week. Bai Lu would participate in the recording of the variety show " Bai Yue Fan Xing " after " Lin Jiang Xian " was completed. Previously, there was news that Ren Jialun and Bai Lu had participated in a variety show together, but there was little interaction on the show. Other than the necessary drama announcements, there was almost no interaction. Even if they recorded variety shows together, there were very few conversations. They would even sit separately when they transferred to the bus, which was obvious to avoid suspicion. However, they had once participated in a double interview with " The Godly Drama Is Bright." In the interview, Bai Lu revealed that both of them had bad backs. One could not bend down, and the other could not straighten up.

There were some ancient romance novels that involved Qi Hao and Gu Jinli. From some of the plot fragments, one could tell that Gu Jinli was in a more complicated situation in the story. If he had to take care of Yin Suwan's daily life, Qi Hao would even use the servant girls around her to threaten her. On their wedding night, Qi Hao had stabbed Gu Jinli's chest with his sword. She wanted to escape from Qi Hao but was imprisoned physically and mentally. After she was fed abortion medicine, her heart turned ashen. In the end, she jumped off the cliff, and Qi Hao screamed heart-wrenchingly. In the novel " Hatred of Mandarin Duck: How to Have Joy with Qing ", these two characters were portrayed more fully. The author, Clear Soup, had buried a lot of foreshadowing in the story to make them lively and interesting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

On the surface, Zhang Chulan was lazy, easy-going, and liked to complain, but in reality, she was meticulous and had a temperament that far surpassed others. She was a person who was more rational than emotional. In his experiences in the variant human world, he could often understand the situation and cleverly deal with the schemes and struggles of various forces. For example, he knew that his identity as the successor of the Qi Body Origin would attract covetous eyes from all sides. Therefore, in the whirlpool of conflict in the supernatural realm, on the one hand, he used the contradictions of all sides to protect himself, and on the other hand, he pushed things towards his own goal. In Chen Duo's case, he seemed to have removed himself from the incident, but in fact, he was the only one who could see through Chen Duo's inner desires. When he was being used to break into the Tang Sect, he was still able to deal with this complicated situation even though he was being schemed against by various forces. All of this reflected his ability to see through the world in the complicated variant human world. The original manga " Under One Man " was equally exciting.
