The following is a large class of bacteria hide-and-seek lesson plan and reflection: ** 1. Teaching plan ** #Germ Hide and Seek ##(1) Activity Target 1. Understand the dangers of bacteria and improve your knowledge of them. 2. It could accurately tell the locations where the bacteria hid and the effective methods to remove them. 3. Through stories and games, children's desire to explore was stimulated and their logical thinking ability was cultivated. 4. Guide children to develop good hygiene habits and strengthen health awareness. ##(2) Event preparation 1. Self-made bacteria props used to visualize the image of bacteria. 2. Make pictures or cards of various scenes (such as kitchen, bedroom, bathroom, outdoor playground, etc.) and hide small marks of possible hiding places for bacteria in these scenes. 3. Prepare some cleaning supplies (such as soap, hand sanitizer, disinfectant wipe, etc.) or pictures. ##(3) Activity ### 1. lead-in portion (1) Carry out a small "guess" activity. The teacher hid the homemade bacteria behind her back and said to the children,"Children, today the teacher brought a mysterious little guest. This little guest is very small, so small that it is difficult for our eyes to see it directly. However, it can bring us a lot of trouble. Guess who this little guest is?" Guide the child to guess that it was bacteria based on his previous knowledge and experience. (2) The teacher took out the bacteria props and showed them to the children. He asked,"Children, where do you think the bacteria are?" Let the child speak freely, and start to stimulate the child's thinking about the hiding place of the bacteria. ### 2. Story telling and interaction (1) The teacher told the story of Germs Hide and Seek: "Children, there is a group of bacteria babies. They are very naughty. They looked everywhere for a place to hide. The bacteria babies flew to the kitchen and hid on the dirty plates. They flew to the bedroom and hid in the dirty corners. They even ran to the bathroom and hid in the wet towels. They also came to the outdoor playground and hid on the small ball that the children took without washing their hands after playing. As long as it was dirty and unsanitary, they would be there. Moreover, when the children accidentally touch these bacteria babies and use their hands to eat or rub their eyes, the bacteria babies will run into the children's bodies. This way, the children may fall sick and uncomfortable." (2) After the story, the teacher asked,"Children, where are the bacteria babies in the story hiding?" Guide the child to recall the content of the story and answer the places where the bacteria hide, such as the kitchen plate, the corner of the bedroom, the bathroom towel, the playground ball, etc. (3) Ask again: "Then, children, if the bacteria baby runs into our bodies, what will happen to us?" Let the child think about the dangers of bacteria, such as getting sick, having a stomachache, coughing, and so on. ### 3. Game: Where Are the Germs? (1) Divide the children into several groups. Each group will be given a picture or card containing different scenes (such as kitchen, bedroom, bathroom, outdoor playground, etc.). (2) The teacher said,"Children, now the bacteria babies are playing hide-and-seek again. They are hiding in some places in these pictures. Let's look for it together." The children had to find the places where the bacteria might hide in their group's pictures (the small marks they had marked before), such as the unwashed vegetables in the kitchen picture, the unmade bed in the bedroom picture, etc. (3) Each group would take turns to share the hiding places of the bacteria they found. The other groups could supplement them. (4) Teachers summarize and comment on the results found by the children to deepen the children's understanding of the hiding place of the bacteria. ### 4. Bacteria-removal battle (1) The teacher took out the cleaning products (soap, hand sanitizer, disinfectant wipe, etc.) and introduced them to the children: "Children, although the bacteria baby is very good at hiding, we also have a good way to deal with them. These are the little helpers that can chase away the bacteria babies." (2) The teacher asked,"Then, children, do you know when you need these little helpers?" Guide the child to answer, such as before eating, after the toilet, after playing with toys, etc. (3) Carry out simulation games. Teachers set up different scenes (such as just playing with toys, just coming back from the outdoors, etc.) and ask the children to choose suitable cleaning products to remove bacteria. For example, the teacher said,"Children, now that we have just returned from playing in the outdoor playground, we may have a lot of bacteria on our hands. What should we use to get rid of them?" Let the child choose hand sanitizer and other cleaning products. ### 5. summary of an activity (1) The teacher and the child will review the content of the activity together and summarize the dangers of bacteria, hiding places, and methods of elimination. (2) emphasize the importance of developing good hygiene habits, such as washing hands frequently, changing clothes frequently, and keeping the environment clean. ##(4) Activity Extension 1. Placing materials in the art design area of the class, encouraging children to make handwritten newspapers or posters about bacteria and how to prevent them. 2. In the family mission, the child and his parents were asked to look for places where bacteria might hide in the house and clean them with the correct cleaning products. ** 2. Reflection ** ###(1) Activity Effect 1. ** Strengths ** (1) Through stories, games, and other forms, children's participation is high. During the story-telling segment, the children listened carefully and actively answered questions during the question-and-answer segment, showing a strong interest in the theme of bacteria hide-and-seek. (2) During the game, the child can use his own observation and thinking ability to find out where the bacteria may hide. In the bacteria removal process, he has a deeper understanding of the use of cleaning products and better achieve the activity goal. (3) The extension of the activity can extend the education from the classroom to the family and art area, further consolidating the children's mastery of the knowledge related to bacteria, and also cultivating the children's hands-on ability and family responsibility. 2. ** Not enough ** (1) In terms of self-made bacteria props, they can be made more exquisite and diverse to better attract the attention of young children. (2) In the game, some children may be too competitive and ignore the careful consideration of the hiding place of the bacteria. They are only eager to answer the questions. In future activities, it was necessary to guide the children to treat the competition in the game correctly and pay attention to the thinking process. ###(2) Enhancement measures 1. He had to invest more time and energy in the creation of props to make the bacteria props more vivid and lifelike. For example, he could make bacteria props of different shapes and colors to increase their fun. 2. In the game segment, the importance of thinking was emphasized in advance. Children were guided not only to focus on the results, but also on the process. When the child answered the question, he should ask the child about the process of thinking and cultivate the child's good thinking habits. Read more exciting novels for free
