Activity objectives and key experiences: When children enter the kindergarten, their athletic ability continues to increase, and their movements become more flexible, but they have little understanding of the role and protection methods of the joints of the body, which can easily cause joint strains, falls and bumps during sports. In this way, through interesting joint games and joint performances, children can know the role of joints in human activities and learn how to protect joints during sports. 1. Know that joints can bend the body and play an important role in human activities. 2. Learn simple ways to protect joints. Activity materials and related environment creation: paper plywood, paper clip long arm, string, several watercolor pens, a set of large building blocks. The book area is stocked with books related to human joints and bones. The "Children's Book" has a drawing of human joints. Teachers record the phenomenon of pushing, pulling, pulling and not paying attention to self-protection in children's life and play. 
Add ** notes, no more than 140 words (optional) Preparation for the activity: Have a preliminary understanding of the human skeleton. Understanding and cognition. Guide children to observe and discuss: questions about how various parts of the human body can bend and change. Teachers record the phenomenon of pushing, pulling, pulling and not paying attention to self-protection in children's life and play. Activity process: 1. The teacher takes the children to practice skipping rope outdoors and play the game of "tall and dwarf" and then returns to the class to discuss: how does the rope shake up? Why do people get taller and shorter? (where to lean on the arm when shaking the rope, and where to lean on the leg when squatting or standing up) to trigger the child to understand the joints of the human body. 2. Guide children to find joints on the body, such as wrist joints, elbow joints, ankle joints, knee joints, etc., and discuss again: What can the human body do with these joints? What would the human body be without these joints? Guide children to experience the important role of joints in real life. 3. The game "Performing Joints". The toddler looks for an exposed joint. Boldly draw something with a watercolor pen on the joints. Such as: small insects, small faces, etc. Then move these joints, and find that the figures on the joints will bend and stretch. (Deepen children's understanding of the role of joint bending). 4. The game "Robots and Elves". The children were divided into two teams, one team dressed as a robot to tie the paper splint to the knee joint with a cord, and put the paper clip on the long arm of the arms clamp. A team pretends to be elves, and the teacher pretends to be "engineers" to give orders. The two teams take the building blocks to build a house, and the game sees which team will build the house first, and the two teams swap roles to repeat the game. Spark a discussion: Why is the elf team fast and the robot team slow? Teachers and children summarize together; It is very difficult for the human body to move without joints, but it is very flexible and convenient to move with joints. Joints play an important role in human movement and movement. 5. The teacher asks the children to record their life games, and the screen is pushing, pulling, and dragging. Discuss with your child: How will these phenomena affect your child? What problems are prone to occur? How can we protect our joints from injury? Help children improve their experience in protecting their joints: pay attention not to deadlift or pull the arms of their peers and not push and bump their peers during activities; Pay attention to dodging each other during physical activities to avoid falling injuries; When jumping or lifting heavy objects, take care to protect your joints so that they do not strain or sprain. Again, correct video recording of gaming activities and methods of self-protection. 
Add **Notes, no more than 140 words (optional) Relevant Experience: Painting: Methods of drawing various insects. Health knowledge: health care knowledge of human bones and joints. Activity evaluation: Whether children can pay attention to not pushing and pulling and colliding with peers in activities or sports, and whether they have the awareness and behavior of self-protection. Activity extension and expansion: 1. Create a "I like sports" wall decoration, place the "little person" made by the children's wishes into their favorite sports state, and write their own self-protection methods accordingly. to enhance self-protection awareness and behavior. 2. Communicate and publicize with parents, and pay attention to protecting children's joints in family activities. Remind young children to enhance their awareness of self-protection.
