SectionC
Ⅰ.Materialanalysis
本课是九年级第四单元第二话题的第三课时。
主活动是1a。
1a是承接SectionA和SectionB设计的。
因为在这两个Section里总是提到Mars，学生已经对它产生了兴趣。
“宇宙”属于“自然”的一部分。
而“自然”正是课程标准要求的话题。
1b属于理解型任务，学生如果能独立完成表格，也就说明他们已经掌握了1a的内容。
1c看似让学生讨论，其实通过学习1a,学生都能对所给的问题作出正确的判断。
2这个任务是为3a和3b作铺垫。
学生通过学习本课，可以对火星有大致的了解，也有助于激发学生探索宇宙的好奇心。
3a和3b这两个任务关联性很强，3b只有在学生完成了3a之后才能完成，没有3a的信息，3b就不能进行。
把这两个任务留作家庭作业较好。
