a lot of discipline on people deforestation chart

The first few classes, we studied the relationship between plants and animals and the context, the relationship between biology and biotechnology, yet also of water, soil and vegetation narrations. Students to consider about: animals and the context, plants and the environment, plants and water , What is the relationship of soil? (students response, the instructor summary)
Teacher: Since plants and animals, living entities and nature are so closely narrated, then there is no relationship between male and nature? This lesson, we're working to study this problem.
study a new lesson
1. help students understand the nature and close relationship with the people
think: our annual lives which environmental conditions are required? were the first to breathe, breathe what ? Today is cold or hot? It also says what? days have been dingy, no sun OK?'s clothing, food, asylum, necessary things, questing the source of trace get busy? (Health Yes, the division summary)
Summary: Environmental conditions necessitated for human life, mm water, air, temperature, brightness, etc., human food, clothing, housing entire the needful things, and both are made from nature. people survival is inseparable from nature.
2. guiding students to understand the human understanding, use and transform the natural process of the destruction of nature
(1) to produce images of human destruction of nature to generate side edge
explain: Since there are person creatures ashore the planet, human beings because their own survival, proceed to understand the nature, use of normal and modified normal, undressed from the premier to the present wrap clean, people's productivity and living criteria amended. This fully demonstrates the inseparable ecology of human subsistence. However, in the lesson of human existence, humans have broke ecology. So what the nature of human erasure of it? students to see pictures.
(2) group Discussion
(3) report on the outcome of debates
Summary: In the course of human conquest of nature, a successful experience, but also failures. the failures, the maximum major thing is the use of natural and modified natural Meanwhile, no attention to protecting nature, they undermine the nature of the serious consequences arising therefrom. For example: the human in order to survive, so that large areas of deforestation, soil erosion; slaying wild animals; for their own selfish interests to the plant wastewater unload river water, dirty waters; industrial air pollution air; pesticide polluted soil, etc., destroyed nature, destroy the ecological equilibrium.
3. to help students understand the nature of human destruction of the discipline after the show
a lot of punishment on human deforestation graph (fruits, pelt, etc.) significantly reduced. timber uses a lot, no wood, no building materials to construct a house, a lot of wood plants as raw materials (eg paper mills) can no produce. will lose the protection of the soil, causing soil erosion. soil erosion will directly influence the evolution of agricultural production and animal husbandry, but also blocked the river, overrunning, human life and property were seriously harmed. forests have the air neat and moist role, a premonitory decrement in forest will affect the weather alterations, which directly or indirectly affect people's lives.
show material, which might be punished by the nature of what it? analyze this picture beyond control, water contamination, what would people have been punished? what people directly affected? what people undergo indirectly? < br> Summary: I have a quite good summary of the students, chemical pollution of the creek water ambition make human subject to many penalties. rill in the noxious matter will be used at drinking water and cooking water instantly into the body, human poisoning . the water can make fish, shrimp and additional toxic substances accumulate in the body; use of this irrigation water will pollute the fields, farms, orchards, vegetable garden soil, so namely the grass, grain, fruits, vegetables, and eat, food, livestock, sheep, pigs, fowls and additional animals, accumulation of toxic substances in the body, people who eat the grain, vegetables, fruits, beef and eggs, will be poisoned.
discussion: the above analysis, what are your thoughts?
Summary: Through the on thinking, we kas long asall things in nature are interrelated, and one was destroyed, other districts will also be affected, directly alternatively indirectly, the menace to human existence, nature and many people are punished.
4. help students understand the human use and transform the nature, we must pay attention to nature conservation
discussion: from nature to punish, we use and transform the nature, we must disburse attention to nature preservation. How does nature maintenance? answer: we ambition to defend nature, air, soil, rivers and mountains, nature conservation of plants, animals, primarily those of infrequent plants and animals, but also to protect the natural treasures underground hh short, manifold aspects of nature conservation. conservation of nature is to protect the environment for human life, everybody should attention, everybody ought attempt.
face lotion is water vapor to manner one object O ℃ underneath the ice. winter a.m., the temperature of the ground and vegetation, often diluted to the emulating O ℃; water vapor in the air encounter these chilly object, it will form ice crystals, attached to these objects, this is the cream. we think that frost may also like Like dew formation of water vapor in the cold, the temperature of the formation of frost formation exposed than the lower temperature. To validation this hypothesis is to be exposed for the simulation experiment as: a damp cloth on the table shop to make room for the cloth with extra water vapor; to put a cloth fraught with ice Tietong, in order to lower the temperature of Tietong, you can increase some salt to the ice.
