I’m excited about the things that will be discovered in the future
Section C
Ⅰ. Material analysis
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Section A 和Section B 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。
