There were many reactions that could occur with lime. First of all, the reaction between calcium dioxide and water would produce calcium dioxide, which would release a lot of heat during the reaction process. For example, in the self-boiling pot heating bag, quicklime (calcium dioxide) was the main heat source after coming into contact with water. Secondly, the interaction between the calcium dioxide and the indicator caused the purple litmus test solution to turn blue, and the colorless phenylethanes test solution to turn red. In addition, calcium dioxide can react with some non-metallic compounds to form salt and water; it can also react with some acid to form salt and water; it can also react with some salt to form another base and another salt. In addition, the production of calcium dioxide is mainly achieved by roasting limestone (carbon dioxide), and the process includes raw material preparation.(screening, crushing, drying, and other pre-treatments of limestone), roasting (sending limestone into a calciner and heating it at a high temperature above 800 ° C to decompose it into calcium dioxide and carbon dioxide gas), cooling (using cooling equipment to cool the high-temperature calcium dioxide to normal temperature), screening and packaging (screening and packaging the cooled calcium dioxide), and tail gas treatment (dust removal, sulfur removal, detoxification, and other treatments of carbon dioxide and other tail gas generated by roasting), etc. Read more exciting novels for free
The following are some of the key points to reflect on the teaching plan for the small class of Candy Bag Art: ** 1. Achievement of the goal ** 1. ** Knowledge and Skills ** - In many candy-wrapping art lesson plans, the goal usually included training children's hands-on skills, such as learning the candy-wrapping movements (wrapping, twisting, etc.). Judging from the work and operation process completed by the child, if the child could skillfully complete the action of wrapping the candy, such as successfully wrapping the candy with a candy wrapper and tightening it, it meant that the skill goal had been achieved. However, if the child has more difficulties in the operation, such as difficulty in grasping the strength of twisting or too many wrinkles when wrapping candy, it may reflect that the demonstration of the action is not clear enough or there are insufficient opportunities for practice. - For some of the goals mentioned in the lesson plan, such as feeling the variety of candy and the beauty of the color of the candy wrapper, you can observe whether the child has attention and interest in the color and pattern when choosing the candy wrapper. If the child could take the initiative to choose different colors and patterns of the candy wrapper, and mention the beauty of the candy wrapper during the operation, then this goal would be better achieved. On the contrary, it may be necessary to strengthen the guidance in the teaching, such as adding a special appreciation segment to guide the child to observe the characteristics of the candy wrapper more deeply. 2. ** Method and process ** - In the process of guiding children to explore the method of wrapping candy, it was important to give children enough space for independent exploration. If the child could actively try different methods when exploring the candy bag and could understand the correct method in the later demonstration session, it meant that the exploration session in the teaching method was more reasonable. However, if the child was still confused about the candy wrapping method after free exploration, it might be because there was not enough time to explore or the materials provided were not convenient for the child to operate. - Using nursery rhymes to help children memorize the steps of wrapping candy was also a method. If the child could recite the nursery rhyme and wrap the candy during the operation, it meant that this teaching method had a positive effect. If the child was not interested in the nursery rhyme or could not associate the nursery rhyme with the operation, it was necessary to consider whether the fun and simplicity of the nursery rhyme were appropriate. 3. ** Emotions, attitudes and values ** - Some of the lesson plans were to help Little Bear's situation, hoping to cultivate children's feelings of helping others. During the activity, you can observe whether the child actively participated in the activity of wrapping candy for the bear. If the child showed high enthusiasm and could politely interact when giving candy to the bear, it meant that there was a certain effect in emotional cultivation. If the child is indifferent to the situation of helping the bear, it may be necessary to create a more vivid situation or adjust the compatibility of the situation with the child's interest. ** 2. Teaching process ** 1. ** Introduction Stage ** - If the children could quickly be attracted to and understand the lesson plan introduced by the situation such as the shortage of the bear candy shop or the candy placed during the New Year, it meant that the introduced situation was related to the child's life and was interesting. However, if the child had difficulty understanding or was not interested in the introduction, they needed to re-examine whether the introduction content was in line with the cognitive level and life experience of the children in the small class. For example, for children in small classes, an overly complicated story background might confuse them, but a simple and direct introduction that was closely related to daily life (such as his experience of eating candy during the New Year) might be more effective. 2. ** Material preparation ** - The materials provided, such as candy paper, foam blocks, plasticine pills, etc., should be suitable for small children to operate. If the material is easily damaged (such as too thin candy paper) or too hard (such as materials that are not easy to shape), it may affect the child's operating experience and the effect of the work. At the same time, the amount of materials should also be sufficient to prevent children from affecting the progress of the activity because of fighting for materials. 3. ** Guidance segment ** - In the process of children's operation, the teacher's itinerant guidance was crucial. Teachers needed to pay attention to each child's operation and give affirmation and encouragement in a timely manner. If the teacher could provide individual guidance for different problems of the child during the guidance process, for example, to demonstrate and correct the child who did not wrap the candy correctly, it would help to improve the child's operational ability. However, if the teacher's guidance is too broad or fails to discover the child's problems in time, it may cause the child to repeat the mistakes in the operation. 4. ** Exhibition segment ** - Showing off the candy that a child had wrapped could enhance the child's self-confidence and sense of accomplishment. If the child was able to introduce the candy to his or her peers and share his or her results, it meant that the demonstration had played a positive role. If the child is not enthusiastic about the display, he may need to adjust the way of the display, such as adding some interesting elements, such as arranging the displayed candy into a candy park. ** 3. Extension and expansion ** 1. Some of the lesson plans mentioned extending the activities to regional activities, such as setting up a "candy house" game and providing more materials for making decorative candy for children to continue exploring. This was a very good way to expand, allowing children's interests to be further extended. However, if the materials in the regional activities are not updated in time or the connection with the teaching activities is not close enough, it may affect the enthusiasm of the children to participate. 2. From the perspective of the teaching plan as a whole, one could also think about how to combine the art activities of wrapping candy with education in other fields, such as letting children tell stories about candy in the language field, or learning the concept of numbers by counting candy in the mathematics field, so as to achieve a more comprehensive early childhood education development. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is an example of reflection on the first lesson of the online kindergarten course: ** 1. Teaching content ** 1. ** Attraction of content ** - In online classes for children, the fun of the content was crucial. Perhaps in the first lesson, some of the teaching content did not fully attract the attention of the children. For example, if the curriculum was based on simple knowledge and lacked vivid stories, children's songs, or game elements, the child might quickly lose interest. The cognitive characteristics of young children determined that they were more inclined to intuitive, vivid, and interesting content, such as bright-colored animations and simple and easy-to-remember children's songs. 2. ** Difficulty and Adaptability of the content ** - For online courses for young children, the difficulty of the content needed to be accurately grasped. If the content is too simple, the child may feel that it is not challenging enough to stimulate their desire to explore. On the other hand, if the content is too difficult, the child will feel frustrated. In the first course, some of the teaching content might not be well adapted to the child's development level. For example, in some manual courses, the steps were too complicated and it was difficult for the child to complete them independently. It required too much assistance from parents, which might affect the child's enthusiasm for participation. 3. ** Diverse content ** - The first class might not have Content diversity content. Children needed to develop in language, art, health, science, and many other aspects. If the curriculum focused on a certain field, such as too much language teaching and lack of artistic creation or sports activities, it might not be able to fully meet the needs of early childhood development. Moreover, a single form of content could easily make children feel bored. It should be a combination of storytelling, children's songs, hand-made, simple body movements, and other forms. ** 2. Teaching methods ** 1. ** Interactivity ** - The interaction with the children was the key in the online course. In the first class, there might not be enough interaction. For example, it was only a one-way explanation by the teacher, and the children were only passively watching. They lacked questions, answers, group discussions (although group discussions were difficult to achieve, they could be guided through small interactions within the family), and other links. When interacting with children, you can use more interesting ways, such as showing props on the screen to guide the child to say the name, or asking simple questions for the child to answer with expressions or simple words. 2. ** Parents participate in guidance ** - Children's online courses could not be separated from the assistance of parents. In the first class, there might not be enough guidance for parents. For example, parents were not given enough detailed instructions, causing them to be at a loss when helping their children learn. Parents should be informed in advance of the goals of the course, the key content, and how to guide the children to participate in the interaction. Parents should also be provided with some simple supplementary teaching resources, such as daily items that can be used at home to complement the course content. 3. ** Teaching rhythm ** - It was very important to grasp the teaching rhythm for the children's online courses. In the first class, there might be problems with the pace being too fast or too slow. If the pace was too fast, the child might not be able to keep up with the teaching process and fully understand the content; if the pace was too slow, the child might be distracted. For example, in the story-telling segment, the speed of speech and pause time should be adjusted according to the child's reaction. In the activity segment, the child should be given enough time to operate and explore instead of rushing to the next segment. ** 3. Technology and Equipment ** 1. ** Technology stability ** - In the first class, he might have encountered some technical instability. For example, the video was stuck and the sound was unclear, which would affect the child's learning experience. He needed to test the equipment and network in advance to ensure the fluency of the course. They could choose a stable online teaching platform and inform parents of simple solutions to technical problems, such as reloading the page, checking the network connection, etc. 2. ** Equipment operation convenience ** - Consider the convenience of the equipment for young children. If the course interface was too complicated and difficult for children to operate, it might affect their participation. After the first lesson, the course interface could be optimized and simple operation buttons could be set up, such as start, pause, next page, etc. It was convenient for children to operate with the help of their parents. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
