The second photo of the oxygen nature part、The 5th picture is 188bet online sports betting 188bet app not clear，It is not convenient for students to analyze and observe。2. When exploring the condition of oxygen burning，No experimental method that emphasizes control variables without focusing on。3. The previous content explained a bit slow，The content of the fire extinguishing part is a bit fast，Need to control it in time。Teacher Si Yue, a young teacher who has just stepped onto the three -foot podium, felt deeply after listening to it: I introduced the enthusiasm of students' learning of this lesson through the experiments of the research results and the flame palm of my country，and can improve everyone's national pride，The atmosphere of the classroom is active; the paper is very clear，In the long period of writing, let students read a few more times more times will not let the classroom cold，Deepen the memories of the students。

"Everyone picks firewood flames high"，Alignment of the chemical group，The chemical classroom of Xi'an Economic Development 188bet review No. 1 Middle 188bet app School will be more wise and vitality。
