Reflection on the relationship between the shadow of the sun and the object
The following is an example of a reflection on the relationship between shadows and objects under the sun: ** I. Achievement of teaching objectives ** 1. ** Knowledge target ** - In the lesson plan, the aim was to let the middle class children understand that shadows were formed by objects blocking the sun. Most children could understand this concept after the activity. Through hand shadow games and observing the shadows of themselves and other objects, children could intuitively perceive that shadows were produced when objects blocked the sun. However, there were still a few children who did not have a deep understanding of this concept. In the follow-up questioning session, they could not accurately describe the reason for the formation of the shadow. Perhaps in the teaching process, the explanation of this abstract concept was not easy to understand. More examples or more vivid methods were needed to explain. 2. ** Skill Target ** - The activity was designed to let the children draw shadows to train their hand movements and observation skills. From the works of children, most of them could draw the shadow shape of simple objects, but the accuracy of drawing the shadow outline needed to be improved. This might be because the teacher's demonstration and guidance were not detailed enough when the children were drawing shadows. They did not fully emphasize the corresponding relationship between the shape of the shadow and the shape of the object. At the same time, in the activity of observing the changes in the shadow, the children could find that the shadow would change its size and direction with time (the change in the position of the sun). However, as for how to accurately describe this change, the children still lacked the corresponding vocabulary and expression skills. In the future, they needed to strengthen the guidance in this aspect. 3. ** Emotional goal ** - The entire lesson plan was designed to stimulate children's curiosity and desire to explore the shadow phenomenon. Judging from the children's performance in the activities, they showed a strong interest in shadow games and actively participated in activities such as shadow games and stepping on shadows. However, it was not enough to guide children to explore the other mysteries of the shadow. For example, in the discussion session, children's thinking was mostly limited to the questions raised by the teacher, and there was no more active questioning and exploration. Teachers should encourage children to raise their own questions and explore independently in future teaching. ** 2. Teaching content ** 1. ** Selection of content ** - Choosing the relationship between shadows and objects as the teaching content was more suitable for middle class children because shadows were a common phenomenon in children's daily lives, but they did not understand the principle behind it. Through simple experiments (such as using objects to block the sun to observe the shadow), games (hand shadow game, stepping on the shadow game) and other methods to let children explore the relationship between the shadow and the object, the content is interesting and operational. However, in terms of depth of content, some special situations about the changes of shadows of different shapes could be added, such as the shape characteristics of the shadows of curved objects, to further expand the children's cognition. 2. ** Organization of content ** - The organization of the teaching content basically followed the principle of from easy to difficult, from intuitive to abstract. First of all, the concept of shadow was introduced through shadow games, so that children could be interested in shadows in a relaxed and happy atmosphere. Then, by observing the shadows of different objects under the sun, children could have a preliminary understanding of the relationship between shadows and objects. Finally, through drawing shadows and discussing the changes of shadows, children could deepen their understanding of this relationship. However, the transition between the various links could be more natural and smooth. For example, the transition from shadow games to observing shadows could be added with some guiding words to let the children better understand the connection between these two links. ** 3. Teaching Method ** 1. ** Game Teaching Method ** - The use of game teaching methods such as hand-shadow games and shadow-stepping games effectively attracted the attention of children and stimulated their interest in learning. In the process of playing, children could learn the relationship between shadows and objects. However, during the game, due to the excitement of the children, sometimes they would deviate from the teaching goal. For example, in the shadow stepping game, some children paid too much attention to the fun of chasing and neglected to observe the changes in the shadow. In the future, teachers needed to better control the rhythm of the game. While ensuring that the children had fun, they could also guide the children to pay attention to the teaching focus. 2. ** Visual Teaching Method ** - By letting the children directly observe the shadows of objects under the sun, this intuitive teaching method allowed the children to have the most direct feeling of the relationship between shadows and objects. However, in the process of intuitive teaching, the teacher's guidance was not detailed enough for some observation points. For example, when observing the changes in the shadow at different times, the teacher could provide some simple measuring tools (such as a short stick) for the child to measure the length of the shadow more accurately. This would enable the child to have a more quantitative understanding of the changes in the shadow. ** 4. Teaching process ** 1. ** Introduction Stage ** - Using shadow games as an introduction was relatively successful. It could quickly arouse the interest of children and mobilize their enthusiasm. However, in the introduction stage, more children could participate in the performance of the hand shadow game instead of just the teacher's performance. This could better stimulate the creativity and imagination of the children. 2. ** Exploration segment ** - In the process of exploring the relationship between shadows and objects, children could get a preliminary understanding of the relationship between shadows and objects through their own hands-on operation (such as using objects to block sunlight) and observation. However, in this segment, the cooperation between children was not sufficient. Children could be divided into small groups and let them explore the shadow together. This would not only cultivate the children's sense of cooperation, but also allow the children to collide with more sparks of thinking in the group discussion. 3. ** Wrap-up segment ** - In the summary section, the teacher's summary of the relationship between the shadow and the object was clearer and more accurate. However, the children could be more involved in the summary. For example, the children could use their own words to describe how the shadow was formed and the relationship between the shadow and the object. This could better test the children's mastery of knowledge. ** 5. Teaching Resources ** 1. ** Resource utilization ** - In the teaching process, the main use of sunlight as a natural light source and some simple objects (such as toys) for teaching. These resources were easy to obtain and were very suitable for the teaching environment of the kindergarten. However, there was still room for improvement in the efficiency of resource utilization. For example, some reflective materials (such as mirrors) could be used to allow children to observe the impact of the reflection of the mirror on the shadow, further expanding the child's understanding of the relationship between light and shadow. 2. ** Resource Expansion ** - In the future, he could further expand the teaching resources. In addition to the use of sunlight, artificial light sources (such as flashlights) could also be introduced to explore shadows in an indoor environment. This would allow children to understand the relationship between shadows and objects more comprehensively in different lighting environments. At the same time, they could use the multi-media resources to play some animated videos about the principle of shadow formation, so that children could understand this phenomenon from different angles.

How did you prepare for the Hengshui teacher establishment exam?
The preparation work for the Hengshui teacher examination is as follows: First of all, the preparation time was usually at least three months, but this was not absolute. It varied from person to person. Normal students had a solid foundation in educational theory, so it was relatively easy to review and prepare for the exam. On the other hand, non-normal students had not studied related majors, which was equivalent to learning a new major, so it might be difficult to review and prepare for the exam. If they waited until the announcement was made before they started planning for the exam, the chances were slim. Secondly, he had to understand the information on the local teachers. There were differences in different regions, including the number of applicants, channels, and time. Finally, after the registration was successful, they had to prepare for the exam in time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Lord Angel can't beat the Archangel
In " Gundam SEED," the Archangel's " Loheng Grin Roan Green " Positron City-Breaking Cannon was extremely powerful. During the period of the SEED, no body or warship could withstand its firepower. Moreover, this cannon defeated the Archangel during the battle of Yakin Durai. The Archangel's " GottfriedMk71 Godfield " 225cm high-energy beam main cannon was less powerful than the Positron City-Breaking Cannon but stronger than the linear railgun. It was also the main force of the Archangel in atmospheric warfare. It could destroy the Nazca class in one strike. The warships that could resist it were known to be the Lord Angel. All of these factors combined meant that the Main Angel was at a disadvantage compared to the Archangel in terms of warship performance. Thus, it would be difficult for the Main Angel to win against the Archangel.

What is the use of urine routine for physical examination in public institutions?
In the physical examination of public institutions, urine routine was a very important examination item. It had many functions: 1. ** Reflects kidney function **: For example, through the detection of urine protein, if the urine protein increases, it means that the kidney has problems with the filtering function of beneficial substances; indicators such as Creonin, Ureaine, and Uric acid can reflect whether the kidney function is damaged; UA indicators can also reflect the metabolism of UA, which is meaningful for discovering diseases such as UA Kidney Disease. 2. ** Understand the status of the urological system **: For the white blood cell indicator in the urine routine examination, if there are more than five white blood cells in each high-powered field, it indicates that there may be a urine infection; if there are more than three red blood cell indicators in each high-powered field, it proves that there is hematuria; urine deposit examination can detect kidney diseases, urological system infection, urolithrosis, and other diseases. It can also determine whether there is the presence of protein urine, red blood cell urine, white blood cell urine, and other conditions. 3. ** Reflects metabolism **: The components in the urine include urea, uric acid, Creonin, and glucose. The content and ratio of these components can reflect the metabolism of the human body. 4. ** Prompt for infection **: In addition to the infection of the urological system, some indicators in the urine routine examination can also reflect the possible infection of other parts of the body. For example, elevated white blood cells may be associated with a general infection, and a positive reading of nitrates may also indicate the presence of a bacteria infection. 5. ** Detection of early kidney disease **: For example, urine micro-protein test. High micro-protein content may mean that the kidney has been damaged. This test can detect kidney disease early so that it can be treated in time. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
