Teaching plan of "Fresh Air, We Love You" in kindergarten's large class art

The lesson "We need fresh air" starts with "fresh air makes us feel comfortable". Through observation, experiment and discussion, students can gradually deepen their understanding of air pollution phenomena and the causes of these phenomena, and understand the harm caused by air pollution. In the specific teaching practice, firstly, a group of fresh natural scenery maps are used to guide students to realize that "fresh air makes us feel comfortable" leads to the topic; Then present a group of air pollution scenes to guide students to compare and find out that the main factor of air pollution in these places is "burning"; This is just what we see. What is the truth? Therefore, experimental inquiry is introduced to guide students to independently design comparative experiments to verify that "combustion will cause air pollution and the degree of pollution is different when different fuels are burned"; Finally, let the students extend the classroom to extracurricular activities in the discussion.

Second, teaching objectives

1. Understand that human activities, including burning, will have adverse effects on the air, and know the harm caused by air pollution to human beings.

2. Through comparative experiments, it is verified that "combustion will cause air pollution and the degree of pollution is different when different fuels are burned", and it is concluded that "we should use low-pollution fuels in our lives".

3. Experience the fun of inquiry activities and establish the spirit of mutual cooperation and willingness to explore.

4. Carefully observe the little things around you, communicate the phenomena found in the observation, and try to tell the scientific truth learned from the observation.

5. Be aware of the importance of consciously protecting the environment.

Third, the teaching focus and difficulty

Focus: guide students to find out what is polluting the air.

Difficulty: According to the existing experience, explain the reason of "asbestos net blackening" and verify that "the air pollution caused by different fuel combustion is different".
