teaching process
I. Overview of water pollution
1. Conceptual water pollution refers to the phenomenon that the chemical, physical and biological characteristics of water bodies are changed due to the intervention of some substances, which affects the utilization value of water, harms human health, destroys the ecological environment and causes the deterioration of water quality.
2. Self-purification ability of water body
Physical purification: mixing, dilution, volatilization, diffusion, precipitation, etc.
Chemical purification: redox, acid-base reaction, decomposition, coagulation, etc.
Biological purification: assimilation, oxidation and decomposition of aquatic animals, plants and microorganisms.
3. Water pollutants Water pollution sources
4. Types of water pollution
(1) chemical pollution
① Inorganic pollutants: acid, alkali and some inorganic salts; The main reason is that pollution has changed the PH value of water, hindered the self-purification of water and corroded ships and submerged structure.
② Inorganic toxic substances: substances with potential long-term danger in heavy metals-elements such as mercury, cadmium, lead and arsenic.
③ Organic toxic substances: fertilizers, pesticides, polycyclic aromatic hydrocarbons and aromatic hydrocarbons-artificially synthesized and difficult to decompose.
④ Aerobic pollutants: carbohydrates, protein, fats, phenols, alcohols and other substances contained in domestic sewage and some industrial wastewater can be decomposed by microorganisms, but a lot of oxygen is needed.
⑤ Plant nutrients: mainly refer to nutrients such as nitrogen and phosphorus in domestic sewage and industrial sewage, as well as nitrogen and phosphorus remaining in farmland drainage.
⑥ Oil pollutants: mainly refer to oil pollution to water bodies, especially offshore oil production and cruise accidents.
(2) physical contamination
① Suspended matter pollution: insoluble matter contained in water, including solid matter and foamed plastics. Suspended solids affect the appearance of water, hinder the photosynthesis of plants in water and reduce the integration of oxygen, which is unfavorable to aquatic organisms.
(2) Thermal pollution: The industrial cooling water discharged directly into the water body without treatment may cause the water temperature to rise, the dissolved oxygen content to decrease, and the toxicity of some toxic substances in the water to increase.
③ Radioactive pollution: The exploitation of radioactive mineral deposits, nuclear tests and the establishment of nuclear power plants have increased radioactive waste water and waste.
(3) Biological pollution of domestic sewage, especially hospital sewage and some industrial wastewater, often brings some pathogenic organisms and affects people's health. 5. World Water Day: 1993, March 22nd every year. 6. Harm of water pollution.
(1) is harmful to human health
(2) Harm to industrial and agricultural production. Eutrophication of water body mainly means that water body contains more nutrient elements, such as nitrogen and phosphorus, which are beneficial to plant growth. Plants are mainly phytoplankton such as algae. Once nitrogen and phosphorus reach a certain concentration, algae will grow wildly. They gather and float on the water, which is called red tide in seawater and water bloom in fresh water. Red tides occur not only in tropical and subtropical regions, but also in temperate and even cold regions, especially in closed harbors.
The wild growth of aquatic plants consumes a lot of dissolved oxygen, but the oxygen in water is insufficient; Aquatic plants proliferate in large numbers, the decomposition of microorganisms is strengthened, and a lot of dissolved oxygen is consumed, so zooplankton in water die because of lack of oxygen.
8, water eutrophication control measures
(1) Prevent nutrients from entering the water;
(2) Control the reproduction of algae in water.
(1) Implement the "Phosphorus Prohibition Order"
② Control farmland pollution.
(3) Sewage treatment adopts chemical methods such as distillation, electrodialysis, ion exchange, etc. to further control the discharge of nitrogen and phosphorus in sewage.
④ Artificial water purification ⑤ Plant water purification
Second, the prevention and control of water pollution
1, water pollution prevention and control principles: prevention, treatment and management prevention mainly refer to reducing pollutants discharged by pollution sources to the minimum through effective control. Governance is to ensure that the sewage reaches the national or local discharge standards before entering the natural water body through the construction of urban sewage treatment plants. Management is the management of pollution sources, water bodies and treatment facilities.
2. Cleaner production: refers to the continuous application of comprehensive environmental prevention strategies in production processes, products and services to reduce the risks to human beings and the environment.
3, the characteristics of cleaner production
(1) cleaner production advocates prevention first.
(2) Cleaner production embodies the intensive growth mode.
(3) Cleaner production embodies the unity of environmental benefits and economic benefits.
4. Basic methods of common sewage treatment methods

Instructional design:
First, the introduction of teaching
Now and in the future, human beings all over the world are facing the threat of resource and environmental problems such as lack of resources, river pollution, air turbidity and mountains of garbage. In fact, in real life, as long as we pay a little attention to the reasonable and moderate packaging of goods, we can avoid the damage of goods in the process of transportation and storage, which is convenient for consumers to carry. However, it exceeds the functional requirements of protecting and beautifying commodities, which will cause waste of resources and environmental pollution.
(Title on the blackboard: Overpackaging wastes a lot)

2. Understand the connotation of Scientific Outlook on Development and improve the ability to correctly handle the relationship between population, resources and environment.
3. Understand the relationship among population, resources and environment, and establish Scientific Outlook on Development.
Teaching emphases and difficulties
China's resources and national conditions are the focus of this class.
Implementing the strategy of sustainable development and adhering to Scientific Outlook on Development are the difficulties in this process.
Preparation before class
Teacher: Collect information about the national conditions of resources in China and think about the harm caused by population, environment and resources.
Student: Check the information.
Teaching design
First, set questions and introduce new lessons.
Earth-she is the mother of all life in the world; She is the source to protect the growth of these lives; She contains all modern civilizations; She symbolizes our most important wealth. Earth-she is our eternal hope, the vitality that we have continued from generation to generation, and our home!
Summary: Be kind to the earth, this is our common home.
Second, educational activities.
Activity 1: Origin of Earth Day
Writing on the blackboard: implementing the strategy of sustainable development
1, our common home
Do you know the origin of Earth Day? Do you know anything about the earth now?
Thinking example:
(1) In order to survive, people are forced to clear forests for land reclamation, cut down trees at will and destroy vegetation. The unreasonable exploitation and utilization of natural resources by human beings is at the expense of destroying the ecological environment in exchange for temporary economic prosperity.
(2) controlling the excessive population growth and carrying out family planning; Implement the strategy of sustainable development.
(3) People's Republic of China (PRC) Environmental Protection Law, People's Republic of China (PRC) Air Pollution Prevention Law, etc.
(4) According to the materials provided earlier, the fate of the earth should be nothing more than two kinds: one is the awakening of mankind, loving the earth and creating a beautiful home together; One is to make the status quo worse, and finally let human beings lose their living space.
Reason: Unreasonable and unscientific development and utilization of resources, resulting in serious waste and loss.
Blackboard writing:
2. Correctly handle the relationship between man and nature.
Nature is the foundation of human existence, and we can neither be its slave nor do nothing; You can't pretend to be the master and give orders to nature at will. Man should live in harmony with nature.
Activity 2: Use your head to draw tomorrow.
What will be the future of mankind? Pessimists described the scene of the end of the world and sounded the alarm for the whole world. People admit that they are facing a serious crisis, but they can work together through Qi Xin to overcome the crisis and seek a new development path.
Writing on the blackboard: Second, take the road of sustainable development.
1. Population, environment and resources issues
Population, environment and resources are all development problems in essence. Today, the rapid increase of population, the shortage of resources, the deterioration of environment and the ecological crisis have directly threatened the survival and development of mankind. It has become a common understanding to implement the strategy of sustainable development.
Write on the blackboard: 2. Carry out the strategy of sustainable development and stick to Scientific Outlook on Development.
The connotation of sustainable development: it not only meets the needs of contemporary people, but also does not harm the development of future generations' ability to meet needs.
Requirements of sustainable development: Human beings live in harmony with nature, and they are aware of their responsibilities to nature, society and future generations.
Exhibition materials: Building a harmonious socialist society is the goal and task put forward by the party and the state according to the new requirements of China's economic and social development in the new century and new stage and the new trends and new characteristics of our society. The harmony between man and nature is one of the basic characteristics of a harmonious socialist society. Harmony between man and nature means production development, affluent life and good ecology.
Please use your theoretical knowledge to write the main points of the keynote speech at this seminar.
Summary:
(1) Sustainable development refers to the development that not only meets the needs of contemporary people, but also does not damage the ability of future generations to meet needs.
(2) Population, resources, environment and economic development interact, influence and restrict each other.
(3) China has a large population, relatively insufficient resources, and the environmental situation is not optimistic. The grim situation of population, resources and environment restricts the economic and social development of China.
(4) Harmony between man and nature is one of the basic characteristics of a harmonious socialist society. In order to realize the harmony between man and nature, we must correctly handle the relationship between population, resources, environment and economic development and take the road of sustainable development, instead of sacrificing resources and environment for temporary economic development. Only by implementing sustainable development can we achieve production development, affluent life and good ecology, and achieve harmony between man and nature.
Then, please think carefully after class. What can we do to protect the environment and save resources?

Chapter VIII Teaching Purpose of Environmental Education Teaching Plan
1, to understand the causes of the greenhouse effect;
2. Know that the greenhouse effect does more harm than good to human beings;
3. Combined with the causes of the greenhouse effect, learn the methods to alleviate the greenhouse effect.
Harm of greenhouse effect in teaching focus
Teaching difficulties and methods to slow down the greenhouse effect
teaching process
First, what is the greenhouse effect?
-Introduction: The reason why greenhouse gases such as carbon dioxide produce greenhouse effect: Carbon dioxide and other gases play the role of glass cover or plastic greenhouse on the ground, which makes the ground temperature rise, which is often called "greenhouse effect". (Available icons)
—— Memories: The role of plastic glass greenhouses and glass greenhouses. Understand the main reasons for the increase of greenhouse gases;
1, fossil fuel combustion emits more carbon dioxide;
2, deforestation, resulting in a reduction in the amount of carbon dioxide consumed by nature.
Second, the advantages and disadvantages of the greenhouse effect
-Guide students to read relevant materials in textbooks and try to summarize and sort them out. Affirm the students' conclusions, and then show their own conclusions: the greenhouse effect is beneficial to people's lives to a certain extent, but it also has more disadvantages, which are reflected in:
1, sea level rise, resulting in the inundation of coastal cities and some island countries;
2. The high temperature in some land will bring about the adjustment of the global economic structure;
3. The ecosystem will be unbalanced and some species will become extinct;
4. The prehistoric deadly virus that has been frozen for more than 10 million years may reappear in broad daylight, causing the world to fall into epidemic panic and seriously threatening human life. Read the materials, summarize the teaching materials, exchange and discuss, and form your own views.
What can we do in the face of the greenhouse effect?
-Introduce the Kyoto Protocol and guide students to discuss: How to effectively alleviate the greenhouse effect?
Provide two ideas:
1, reducing carbon dioxide emissions;
2. Increase the consumption of carbon dioxide by nature.
-discuss the harm of the purpose of the United States' refusal to sign the Kyoto Protocol and form a certain awareness of environmental protection. Discuss the feasible ways and practical operation to alleviate the greenhouse effect.
Corresponding measures:
Fourth, teaching reflection:
1. Develop new energy sources: solar energy, hydropower, wind energy, garbage energy, etc.
2. Plant trees, starting with me.
