The theme of this activity is the mirror. In the activity, I didn't tell my children the principle of mirror image directly. Instead, children's favorite animated characters are taken as scenes, and the knowledge and experience of children's original magnifying glasses and haha mirrors are used as carriers to guide children to explore and discover the imaging problems of flat mirrors. The children are very interested, and the whole activity can be actively thought and explored under my guidance, and the goal of the whole activity is also relatively high.

Success:

1, with distinct levels and situational guidance, stimulates children's desire to explore.

2. The operation process has clear guidance, from easy to difficult, and goes deep at different levels to achieve the goal smoothly.

There is a problem:

1. When setting the scene, the imaging problem of the haha mirror is ignored. This problem has been considered when designing this scene, but no better method has been found. I just wanted to apply this principle at that time, but it was not rigorous enough. )

2. When guiding children's operation, the problem of imaging (overlapping) after two plane mirrors are placed in parallel is ignored. Although no child has raised it, as a guide for children, it is still necessary to explain it properly or introduce it briefly.

Through the tempering of this teaching activity, I have a deeper understanding and understanding of the organization of scientific activities, and I will be more rigorous in the process of organizing scientific activities in the future.
