In this activity class, my material comes from the things around children, and the materials that children are easy to access at ordinary times make children feel that science is around. During the whole activity, children can actively participate in the activity, especially when watching the video teaching materials, seeing many plants around them has aroused great interest of children. In the process of operation, there was some confusion, and some children did not choose seeds according to the teacher's instructions. Because they were so excited, they chose many seeds to mix together. When naming seeds, some children choose their favorite seeds, but they can't name them. Under my guidance, children can know their names. When selecting seeds according to their characteristics, individual children failed to choose seeds according to their characteristics, or chose their favorite seeds, which may be due to insufficient guidance from teachers. In short, the whole activity level is clear, step by step, from easy to difficult, and gradually solve the teaching focus, so that children can master knowledge in the process of making friends with seed babies.
