But they often ignore it,
These easily overlooked rotation phenomena are of great help and use to people's lives.
The mystery of rotation makes children have a strong interest and desire to explore. Children are born with curiosity and desire to explore. Curiosity is the expression of the inner essence of children's life, and it drives children to explore and seek knowledge. Children's inquiry and study in the field of science are often directly driven by curiosity and interest. It can be said that curiosity and interest are the basic prerequisites for children to actively carry out scientific inquiry and research. In view of this characteristic of children, we start with cultivating children's love and learning of science and stimulating their interest in exploring scientific activities, and carry out various scientific activities. This activity allows children to use a variety of ways to make objects rotate in operation activities and cultivate their ability to actively participate in exploration activities. Understand that rotation is a kind of exercise, feel the importance of rotation to the body, and know how to protect your body.
Activity goal: 1. Investigate rotating objects, accumulate experience about rotation, and understand that rotation is a way of exercise. 2. Simply classify the rotating objects according to the different dynamics, feel the convenience brought by modern technology, and have the desire to invent and create. 3. Feel the importance of rotation to the body and know how to protect the body.
Key points and difficulties:
Yang: It's over.
Yang: I found things that can rotate, such as windmills, hula hoops, wheels, frisbees, carousels, roller coasters and gyroscopes.
......。
Teacher: You are really capable. I also found something that can rotate. Let's have a look!
There are washing machines, airplanes, ship propellers, waterwheels, balls, skipping ropes and iron drums.
Yang: Teacher, I don't know two others.
Yang: Yes.
The teacher concluded: both teachers and children are very capable. It's really great that we found so many things that can be rotated. Praise yourself (hey, hey, we're great).
Yang: As soon as the windmill blows, it turns. When the electric fan is plugged in, it turns.
Teenager: the hula hoop is turned by people, and the start switch of the merry-go-round is turned.
Children and teachers play together, observe together and then play classified games. Prepare some cards for children that can rotate objects. Please stick them on the blackboard as required. 1, wind-transferred goods 2, manpower-transferred goods 3, electricity-transferred goods 4, water-transferred goods.
Yang: My father said that cars run on engines, but I don't know about planes and ships.
Teacher: Jin Woo gave a good answer, but it was not very detailed. Let's treat this question as homework. Let's go home and study with our parents and explore again next class.
Yang: The electric fan is getting cold. The washing machine can help my mother wash clothes. The merry-go-round in the amusement park is very interesting. ...
Summary: Rotating objects are of great use to our lives.
Fourth, let children discover that rotation is a way of exercise through games.
Yang: The teacher turned his head, his arms, his hands and feet. ...
Teacher: Come and try. Be careful not to hurt yourself and other children.
Young: fingers, eyes, and many places are turning. We can dance, play ball and make handicrafts. ...
Young: Don't bump or beat yourself, and don't play in dangerous places. ...
Conclusion: We must protect the extension of our physical activities: explore with our parents how the propellers of airplanes and ships rotate. Reflection: This activity is a scientific exploration activity that children are interested in. It is of great use for children to explore so many rotating objects in life through activities. Every link in the activity went smoothly, and the children were very interested, but they were not satisfied with the questions raised by the children in the third link. I feel that my knowledge reserve is too small to answer my child's questions satisfactorily, and my child is a little lost. In the future, I will definitely increase my knowledge reserve, seriously study all aspects of knowledge, and strive to give my children a satisfactory answer.
