1. What garbage will be produced in life?

Answer by roll call. Students say that there is any garbage, which may be one-sided from the family. At this time, teachers should give proper guidance: think about what kind of garbage will be produced by study and construction.

2, talk about the understanding of these rubbish. Ask 6-8 people

3, students began to divide garbage from the students' answers to garbage, summed up that some garbage is still useful, but the raw materials are used in the wrong place. According to this standard, let the students sort the garbage by hand.

Through cooperative discussion between teachers and students, the classification of garbage types is completed: recyclable garbage, non-recyclable garbage and harmful waste.

Summary: The garbage that can be used is called recyclable garbage, and the garbage that cannot be used is called non-recyclable garbage. Among the non-recyclable garbage, there are some special garbage (waste batteries, expired drugs, pesticide cans), which we classify separately as one category, called? Hazardous waste? .

Iii. Types of garbage (The following contents are provided by recording)

1. Recyclable garbage: mainly includes waste paper, plastic, glass, metal and cloth.

Comprehensive treatment and recycling can reduce pollution and save resources. For example, every 1 ton of waste paper can be recycled into 850 kilograms of paper, saving 300 kilograms of wood and reducing pollution by 74% compared with the same output; Every time 1 ton plastic beverage bottle is recycled, 0.7 tons of second-class products can be obtained; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.

By calculation? How many poor students can you help? Let the students know the size of 2.4 million yuan.

Discussion: The money spent is 2400000 yuan, which is wasted every day in Beijing, and the way of landfill will occupy a lot of land, which leads people to seek better ways to deal with garbage.

Incineration refers to sending garbage to special institutions for combustion treatment to minimize pollution.

Most areas in China use landfill to treat garbage. At present, it is transforming into incineration.

If you are the head of the environmental protection department in Zhengzhou, and you want to investigate the garbage disposal methods of local residents, please design a garbage classification investigation method according to what you have learned and cooperate in groups. Students rarely come into contact with the design of this type of survey, and teachers show their designs under specific guidance.

After students show their grades, ask a student to play the role of the respondent and answer the survey content designed by other groups. You can also confirm whether the survey method designed by the team is feasible.
