教学目标：                                                       

 

           知识目标：使学生掌握苯分子的结构特点。                                                                                                                                                                                                                                                                                                                          

           能力目标：培养学生逻辑思维能力、观察能力、实验能力、分析问题解决问题的能力。

           科学思想：使学生认识物质结构决定性质，性质又反映结构的辨证关系。

           科学品质：培养学生以实验事实为依据，严谨求实勇于创新的科学精神。

           科学方法：引导学生以假说的方法研究苯的结构，并从中了解研究事物所应遵循的科学方法。
