Where does the paper come from? Reflections on teaching plans

Where does the paper come from? Reflections on the teaching plan are as follows:

1. Activity goal: Understand the origin of ancient papermaking, know that paper was invented by China people, and germinate as the pride of China people. Try to make paper and experience the joy of making recycled paper. Let children be interested in exploring natural phenomena. Cultivate children's curiosity about things, be willing to explore boldly and prepare for experimental activities.

2. Soak waste paper towels and newspaper scraps in water one day in advance to make paper pulp, small sieve, white cotton cloth, net, water, basin and flour stick. Modern papermaking teachers' teaching resources and children's learning resources 4, 18-2 1 page.

3. Activity process: Feel the modernization of papermaking. Watch teachers' teaching resources or read children's learning resources 4. Observe the mechanization process of modern paper machines on page 18- 19. Let the children talk about how modern people use machines to make paper.

4. Understand the origin of ancient papermaking: Teacher: Do you know how the earliest paper was made? Who invented it? The teacher told the story of "Cai Lun and papermaking". Teacher-child communication: talk about how ancient people made paper. Read the paper-making step chart on page 20-2 1 of Children's Learning Resources 4, and the teacher will demonstrate and explain the process of manual paper-making.

5. Children try to make paper in groups: Now crush the paper soaked in water by hand, take it out, and stir it into paste with a blender under the guidance of the teacher to make pulp. Pour the pulp into a large basin filled with water and stir well. Spread soft cotton cloth on a small screen with fine mesh, immerse it in a basin, screen the paper paste flat, and a layer of paper pulp will remain on it, filter out excess water, which is the paper embryo, and dry the paper dolphin.

6. When the paper is air-dried, flatten the paper dolphin with a flour stick and separate it from the soft cotton cloth. Put the paper ring in the sun and dry it thoroughly. Trim the edge of the paper with scissors, and a piece of paper will be finished. Please draw and write on self-made recycled paper and feel the joy of success. Guide children to cherish paper and save paper in their lives.
