Activity reflection:
In the activities, we always carry out the spirit of the Outline. "Children's science education refers to the exploration process that children perceive, operate, find problems and seek answers to the surrounding material world through their own activities under the guidance of teachers." Activity goal: (1) Use multiple senses to perceive the shape characteristics of celery and experience the fun of operation. (2) Understand the benefits of celery to human body. In the first part of the activity, under the guidance of the teacher, children can distinguish the roots, stems and leaves by seeing, smelling and touching various senses, and fully perceive the appearance characteristics of celery; In the second part of the activity, by watching the video, let the children know the benefits of celery to the human body, and under the guidance of the teacher, know that celery contains fiber, which helps us digest food, make the stool unobstructed, and find fiber in celery ourselves; In the last part, children make cold celery by themselves, let them know that celery has many ways to eat, make their mood reach * *, and enjoy their own cooking. In this activity, the children gained rich scientific experience, learned scientific methods, developed their ability and curiosity to explore and solve problems, enjoyed their own success, gained a pleasant emotional experience, cultivated their interest in learning science, and sprouted their love for nature.
There are also some shortcomings in the activities. Because teachers borrow classes, they don't know much about children's early experiences. Therefore, at the end of the cold celery, the requirements were not clearly stated, resulting in the child not operating at first. Some children put too much sugar and some children put too much vinegar. Later, at the teacher's supplementary request, the children learned to cold celery.
