Lecture notes on the simplest organic compound - methane
Yancheng City Wu Zhong middle school Lv Xias to establish students: organic three-dimensional structure model, embodied in how to structure characteristics, methane and organic alkane bonding characteristics from the physical model into a model of thinking in the minds of students, help students from the aspects of chemical bond structure and properties of methane.
[learning situation analysis]
Students already know that methane is a fossil fuel that burns and can recognize the product of combustion from the composition of methane. This chapter mainly considers the teaching again methane, methane is the most simple organic compounds, facilitating students to understand the nature of methane from the structural perspective, the structure and properties of alkanes on organic chemistry, the establishment of learning mode of learning from the perspective of the structure properties of organic compounds. Therefore, the design of teaching, in the junior middle school students based on knowledge, reflect the cognition principle of progressive development: at the same time, taking into account the students already have some relevant physical structure concept should be in the organic compounds in learning hold the relationship between the structure and properties of the three-dimensional structure model of o
