Teachers and children make garbage sorting boxes together and draw recycling signs.
Children's discussion: how to classify garbage? The teacher can demonstrate the classification of some combined garbage, such as the outermost packaging of cigarette cases is plastic, the middle cigarette case is waste paper, and the innermost tin foil is metal; The bottle cap of beer bottles is mostly metal, the bottle body is glass, and the wrapping paper belongs to waste paper.
Let the children operate and sort the things in the plastic cups. According to waste paper, waste plastics, waste metal, waste glass and non-recyclable waste products, put them into their own cartons with recycling marks. Classifying garbage in this way can not only reduce pollution, but also save energy, killing two birds with one stone.
4. The teacher let the children watch the video of garbage sorting and recycling, so that they can learn more about garbage recycling. This method is used to prevent environmental pollution and achieve the purpose of recycling.
