Environment is a necessary condition for human survival. 2 1 century, with the rapid development of science and technology and industrial production, people make full use of the resources on the earth to continuously improve our living standards, but also bring harm to our living environment. There will always be a beautiful living environment for mankind, for ourselves and for our future generations. We should start with the child and protect it. As a primary school teacher, we should cultivate students' behavior habits and virtues of caring for the environment from primary school. It is very necessary to educate primary school students on environmental protection, so that they have environmental awareness and habits from an early age.
First, the student situation analysis:
There are 32 students in Grade One. They have little basic knowledge. Although they may have some good study methods, good study habits and certain environmental awareness and knowledge, they are not systematic and comprehensive. There are differences among students, individual students are unwilling to use their brains, have little interest in learning, and rarely carry out comprehensive practical activities, which are the reasons why they lag behind.
Second, the teaching purpose:
1, students understand the emergence and development of some ecological and environmental problems, perceive the harm brought by these environmental problems, establish environmental awareness, and change the lifestyle that wastes resources and destroys the environment. Learn to start from yourself, start from your side, and take appropriate measures to protect the ecological environment for a long time.
Ideological education:
1, experiencing a healthy life is inseparable from a good environment.
3. Establish an emotional awareness of caring for the environment and protecting nature.
Third, the difficulties in teaching:
1. Cultivate students' feelings of loving nature and exercise their ability of unity and cooperation.
2. Enhance students' awareness of environmental protection and water saving, and establish the good virtue of "starting from me and starting from now".
3. Experience the beauty and harmony of nature and enhance the awareness of protecting nature.
4. Establish environmental awareness from an early age, and turn the understanding of the global environment into concrete actions to protect the earth.
Fourth, the teaching content:
1, start from me and protect green life.
Through activities, educate students to understand the great significance of environmental protection, improve their awareness of environmental protection, stimulate their thoughts and feelings of loving the motherland and protecting the environment, and consciously participate in the practical activities of environmental protection.
Teaching emphases and difficulties:
Fully understand the importance and necessity of protecting the living environment, make clear its urgency and close relationship with each of us, and do not spit everywhere, throw dirty things, trample on the lawn, and pick flowers and leaves at will.
2. Save water.

[introducing new lessons]
I. Biodiversity and its protection
Biodiversity includes all plants, animals and microorganisms on the earth, their genes and ecosystems composed of these organisms and the environment. Protecting biodiversity means adopting conservation strategies and measures at three levels: ecosystem, species and gene.
Biodiversity is the precious wealth left by four billion years of biological evolution on the earth, and it is the foundation for the survival and development of human society. The sustainable development of economy must be based on a good ecological environment and the sustainable utilization of biodiversity. Biodiversity provides us with food, medicine, clothes and housing. It is not only the main target of agriculture, forestry, animal husbandry and by-fishing, but also an important industrial raw material. In addition, biodiversity also plays an important role in protecting soil, conserving water, regulating climate and maintaining ecosystem stability.
1, China's rich and unique' biodiversity'.
(1) is rich in species. There are nearly 30,000 kinds of higher plants in China. Among the 850 species of gymnosperms in 15 family in the world, there are about 250 species in 10 family in China, which is the country with the largest number of gymnosperms in the world. There are 6.347 species of vertebrates in China, accounting for nearly 14% of the world's species.
(2) There are many endemic genera and species. There are the most endemic species in higher plants, about 17 300 species, accounting for more than 57% of the total number of higher plants in China. Among 6 347 species of vertebrates, 667 species are endemic, accounting for 10.5%.
(3) The flora has an ancient origin. Because most areas of China have risen to land at the end of Mesozoic, Quaternary glaciers have not been affected by continental glaciers, and many areas have preserved Cretaceous and Tertiary ancient relics to varying degrees. For example, among the seven existing coniferous families in the world, there are six families in China. Among animals, giant pandas, baiji dolphins and alligators are all ancient relics.
(4) Cultivated plants, domestic animals and their wild relatives are rich in germplasm resources. China is the origin of rice and soybeans.
There are 50 thousand and 20 thousand varieties respectively. There are more than 1,000 species of medicinal plants 1 1000, 42 species of herbaceous plants15, and there are more than 2,238 species of important ornamental flowers originating in 30 genera in China. China is the country with the richest species and groups of livestock in the world, with 1938 species and groups.
(5) The ecosystem is rich and colorful. China has various types of terrestrial ecosystems. Due to different climate and soil conditions, it can be divided into forest 2 12, bamboo forest 36, shrub 1 13, grassland 55, meadow 77, desert 52, swamp 37, alpine permafrost and Liushitan vegetation 17, totaling *. The types of marine and freshwater ecosystems are also complete. Undertaking: The serious loss of biodiversity in China has long attracted the attention of the government. Since 1950s, China has formulated relevant policies and a series of protection measures, which have achieved initial results in biodiversity protection. The Outline of Nature Protection in China published by 1987 is the first programmatic document on nature protection in China, which puts forward the overall strategy and basic principles of biodiversity protection in China and puts forward the overall countermeasures. China attaches great importance to scientific research on biodiversity conservation. China Academy of Sciences has 33 research institutes engaged in this work, and environmental protection departments have also established various types of ecological monitoring stations such as grasslands, deserts and wetlands. China attaches great importance to the publicity and education of biodiversity, and uses radio, television, newspapers and other publicity media to carry out popularization of law and popular science education, and carries out compulsory activities for the whole people in the form of legislation, such as Earth Day on April 22nd, World Environment Day on June 5th, Arbor Day, Bird-loving Week and Wildlife Protection Month. These activities have effectively raised the public's concern and awareness of biodiversity conservation.
2. Biodiversity conservation in China
Biodiversity conservation mainly includes in-situ conservation, ex-situ conservation, scientific research on biodiversity conservation, formulation of biodiversity conservation laws and policies, and publicity and education on biodiversity conservation. Here is a brief introduction to in-situ protection and ex-situ protection.
(1) In-situ conservation is the most effective measure in biodiversity conservation. In-situ protection refers to the protection of valuable natural ecosystems and wildlife habitats in the form of various types of nature reserves (including scenic spots and forest parks) to protect the reproduction and evolution of various organisms in them.
Nature reserves can be divided into natural ecosystem reserves and wildlife reserves. Natural ecosystem reserves can effectively protect forests, grasslands, wetlands and waters and other ecosystems. Any protected area that effectively protects the natural ecosystem will inevitably protect all the species in it. Therefore, all natural ecosystem reserves will provide protection for wild species in the reserves. In addition, there is a wildlife nature reserve in China, which specializes in protecting one or several kinds of wildlife. In a word, nature reserves have played a very important role in protecting biodiversity in China.
(2) Ex-situ conservation can only protect a single species, and it is mainly suitable for emergency rescue of highly endangered species to avoid extinction. For plants, ex-situ conservation mainly refers to the migration of endangered species to botanical gardens, ex-situ conservation bases for rare and endangered plants or breeding centers. For animals, ex-situ conservation mainly refers to the migration of endangered species to zoos, ex-situ conservation bases for rare and endangered animals or breeding centers.
Second, a serious threat to China's biodiversity.
Although China has taken some effective measures to protect biodiversity, China's biodiversity still faces serious threats, mainly:
1) Deforestation is still quite serious, leading to forest fracture and island distribution;
2) The grassland is overloaded and overgrazed, which is seriously degraded;
3) Overexploitation and utilization of animal and plant resources and poaching of rare and endangered animals and plants still exist;
4) Environmental pollution poses a great threat to biodiversity;
5) Environmental changes caused by unreasonable utilization of water resources in arid and semi-arid areas;
6) Invasion of alien species;
7) Overfishing of fishery resources leads to the decline of resources;
8) Tourism, mining, wetland reclamation and other activities also have adverse effects on biodiversity.
Third, the case analysis
Look at the picture below. Which biota has the largest number of species? What is the percentage?
Graph group proportion
Analysis: Will you look at such a pie chart? When studying the data of a group of different projects, when the total data of each project is equal to a whole, we can use a fan chart to represent it. The circle represents the whole, and each small square represents a different item. The size of each block can show the percentage of this item in the whole. As can be seen from the fan chart above, insects occupy the largest part in the whole circle, so the biological group with the largest number of species is insects. The calculation of percentage is to divide the central angle of this block by the central angle of the whole circle (360) and then multiply it by 100% to get the percentage of this block.
The answer is insects. The percentage is 55.8%.
Most crops are often attacked by diseases or parasites. For example, a mold can easily reduce corn production in a large area. Why?
After analyzing the theoretical knowledge we have learned from books, we should try to see if we can analyze some common examples in production practice. Most of the corn varieties planted in a large area of farmland are single, and their genes are almost the same. This species lacking a diversified gene pool is difficult to adapt to diseases, parasites or dry weather, so once attacked by germs, the whole crop will be affected.
The answer is that corn lacks diversified genes in large-scale cultivated fields, so it is difficult to resist the invasion of germs. Once attacked, the whole crop will be affected.
Lesson 2 Marine Environmental Pollution and Ecological Destruction
Teaching objectives:
1, to understand marine environmental problems.
2, a correct understanding of the significance of marine environmental protection, establish the concept of sustainable use of the ocean.
Teaching focus:
Marine environmental protection.
Teaching difficulties:
The concrete implementation of marine environmental protection and the infiltration of ideological education.
Class schedule: one class.
Teaching process:
[Introduction to New Lessons] Ocean problems are accompanied by human exploitation and utilization of the ocean. The ocean has been formed for billions of years, and human beings have used it for thousands of years. However, due to the self-purification ability of the ocean to harmful substances, no serious environmental problems have occurred. Marine environmental problems include two aspects: one is marine pollution, and the other is marine ecological destruction.
First, the current situation and causes of marine environmental pollution and ecological destruction in China.
1, current situation of marine environmental pollution and ecological destruction
2. Analysis of the causes of marine environmental pollution and destruction.
(1) Pollution discharge is increasing, and the marine pollution capacity is limited.
With the development of economy, the output of industrial wastewater in 8 coastal provinces, 1 autonomous region and 2 municipalities directly under the central government is increasing, and the direct discharge of industrial wastewater into the sea is still increasing. At the same time, with the rapid development of offshore oil exploitation and marine transportation, the discharge of marine pollution has also increased correspondingly, but the environmental capacity (pollution capacity) of coastal waters is limited, which is an important reason for marine environmental pollution.
(2) Only taking industrial pollutants as the control object, the effect is not great.
The inorganic nitrogen and total phosphorus that cause eutrophication in the sea area are mainly not industrial pollution sources, and the current measures are mainly industrial pollution control, so the effect is not great.
(3) Comprehensive control measures were not formulated under the guidance of ecological theory.
The inshore sea area is a complex ecosystem composed of coastal terrestrial ecosystem and marine ecosystem. The current "land first and then the sea"
The concept of "ocean" and "controlling the sea by land" urges people to have unlimited land and sea areas for the rapid economic development in coastal areas and the improvement of people's quality of life as soon as possible. The development intensity (scale and speed) of marine resources exceeds the carrying capacity of the sea area, and the economic growth in coastal areas is accelerated, and the economic growth mode is still extensive management; With the continuous growth of population and the improvement of consumption level, the consumption pattern remains unchanged. The consequences of economic and population growth are large resource consumption (low utilization rate), large waste discharge, and an increase in the total amount of pollutants entering the sea, which exceeds the self-purification capacity of the marine environment in some sea areas, destroying the virtuous circle of the "land-sea" composite ecosystem and causing pollution and destruction of the marine environment.
Second, the harm of marine environmental pollution and ecological destruction
1, the harm of marine environmental pollution
(1) Adverse effects of offshore environmental pollution on aquatic resources
(1) the aquatic resources in the inner bay were destroyed.
(2) Offshore fishing grounds have also been damaged to varying degrees.
(2) The impact of marine environmental pollution on human health.
The impact of marine environmental pollution on human health is mainly due to the migration, transformation and enrichment of pollutants through the food chain, which directly harms human health.
(3) The impact of marine environmental pollution on tourism resources.
Oil pollution has seriously damaged coastal tourism resources.
Oil pollution has also been found in some beaches in coastal cities. Excessive coliform bacteria and eutrophication have reduced the water quality of beaches and failed to meet the national water quality standards for beaches, which will definitely have adverse effects on people swimming in beaches.
(4) Harm of marine pollution events such as red tide and oil spill.
2, the harm of ecological damage in the sea area
The hazards of ecological destruction in sea areas mainly include: overfishing, which leads to the decline of fishery resources; Adverse consequences caused by unreasonable development of beaches and deforestation.
(1) Damage of overfishing to fishery resources
The intensity of offshore fishing exceeds the regenerative capacity of aquatic resources, which is a very serious problem for fishery production.
Due to long-term overfishing, the main economic fish resources have declined, and some have been seriously damaged.
(2) Adverse effects caused by unreasonable development of tidal flats.
Tidal flat is an important resource in coastal areas, which should be developed and utilized reasonably. However, some areas, proceeding from local interests, violate objective laws and blindly reclaim land for development, resulting in adverse or even serious consequences. In some places, shallow beaches that have been used for aquaculture have been blindly reclaimed during reclamation, resulting in the decline of aquatic resources.
Three, marine environmental pollution and ecological damage prevention and control countermeasures
1, marine environmental pollution prevention and control countermeasures
The general guiding ideology is: prevention first, source control (whole process control) first; Actively promote cleaner production and promote the transformation of economic growth mode; Strictly control new pollution sources, reduce the emissions of land-based and marine pollution sources, and promote the coordinated development of economy and marine environment.
(1) industrial structure and reasonable adjustment of industrial structure
(2) Improve the industrial layout and optimize the layout of sewage outlets.
(3) Total amount control shall be implemented according to the marine environmental function.
(4) Take effective measures to prevent accidental oil pollution and non-point source pollution.
2, marine ecological environment protection countermeasures
The main contents of marine ecological environment protection are: protecting marine biodiversity, strengthening the management of marine living resources, preventing the degradation of marine ecological environment, improving the ecological environment, maintaining the marine ecological balance, ensuring the sustainable utilization of marine resources and realizing the sustainable development of marine resources.
(1) Current situation of marine ecological environment protection
In order to protect biodiversity and marine ecological environment, since 1970s, China has listed 98 species of aquatic animals and plants as key protection objects, including 53 species of marine plants, and designated closed fishing areas and closed fishing periods, and designated nature reserves to protect rare marine animals and rare aquatic products. By the end of 1997, 39 marine nature reserves have been established, with a total area of 1.29× 104km2. These include bay reserves, island reserves, estuaries and coastal reserves, coral reefs, mangroves, marine natural heritage reserves, seagrass beds and wetlands.
(2) Protecting marine biodiversity
The key protected areas listed in the ninth five-year plan of national environmental protection and the 20xx long-term plan are:
(1) Protect coastal mangroves; Construction of three mangrove reserves from Beicangkou, Guangxi to Zhucheng, Zhangjiangkou, Fujian and Qinzhou Bay, Guangxi, so that the mangrove reserves and management areas account for more than 90% of the total mangrove area; Expand the mangrove area from 1.6× 104hm2 to 3×104hm2; ; Develop mangrove culture technology to make the culture area reach 0.5× 104hm2.
(2) Protect coral reefs and establish three coral reef core protection areas with international influence, namely Xisha Islands, Dongshan Island and Nansha Water Reef; Strengthen the management of coral reef reserves, study coral reef restoration technology, and promote the accelerated growth and restoration of damaged coral reefs.
③ Strengthen the construction of marine nature reserves and establish 60 ~ 80 marine nature reserves with a total area of 1997.
1.29× 104km2 is expanded to 3× 104km2.
(3) Strengthen the management of marine living resources.
In the process of developing and protecting marine fishery resources, we should vigorously develop marine aquaculture resources, consolidate and improve the breeding level of existing high-quality varieties, and actively develop new breeding varieties and high-yield and low-consumption breeding technologies; The state strengthens macro-control and uses economic and legal means to promote the rational development of marine fishery resources and support the development of potential resources; Further improve all kinds of fishery laws and regulations, promote fishermen's participation in the sustainable utilization and protection of fishery resources, realize the legalization of fishery resources utilization and protection, vigorously develop offshore fisheries, and conserve and develop biological resources on the high seas.
(4) Establish marine ecological demonstration area and sustainable development experimental area.
Study and formulate plans for marine ecological environment construction, carry out research on ecological design and ecological construction, and establish important bays such as Bohai Ecological Demonstration Zone for sustainable comprehensive development experiments; We will carry out a pilot project of coordinated development of protection and development in Lu Nan Islands Nature Reserve, and build a man and biosphere reserve.
Fourth, case analysis
Oil is one of the pollutants in large quantities. Ships in coastal industrial production and shipping routes are the main sources of marine oil pollution.
Please discuss the influence of oil pollution on the marine environment through the knowledge introduced in newspapers and periodicals.
Teacher's summary: The realistic and long-term effects of oil pollution on the marine environment are as follows:
1, destroying marine ecology
2. Endangering fishery production
3. Destroy seaside entertainment places.
4. Degrade the whole coastal environment

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.
