人教版高中地理选修1月球和地月系教案
月球对地球的意义月球与地球形影相随，关系密切。月球对地球的影响，主要有以下几方面：1．地球上夜晚的自然照明，主要靠月亮。2．远在古代，人们就根据月相变化的周期，编订历法。我国农历月份的安排，是以月相变化 周期为标准的。农历规定朔为初一，这样，望就在十五日或十六日。我国人民的传统节日，像春节、中秋节就是按农历的月日计算安排的。3．由于地球表面各处所受月球和太阳引力的不同，地球上的水体产生了明显的潮汐现象。4．月球是人类星际航行的第一站。已知月球表面有多种宝贵矿藏；重力较小；没有大气层，利用太阳能的条件较好。如何利用月球的特殊环境，开发月球的资源，以及如 何利用月球作“码头”，使人类更好地研究宇宙，这将是月地关系的新篇章。

5.对土星五号火箭和登月舱的质疑现代航天飞机只能把20吨载荷送上低轨，而当 年的土星五号却能轻而易举地把100吨以上载荷送上地球轨道，将几十吨物体推出地球重力圈，为什么后来却弃而不用，据说连图纸都没有保存下来？6.温度对摄影器材的影响月面白天可达到121°C，据图片看，相机是露在宇航服外而没有采用保温措施的。胶卷在66°C就会受热卷曲失效，怎么拍得了照片？这些人士认为，对以上这一切美国政府一直没个 交代，而知情者由于担心生活和安全受到影响，甚至可能直接遭到了胁迫，至今对此沉默不言。但相信不久的将来，诞生于美苏太空竞赛年代的“登月骗局”定会水落石出。反驳不过，也有许多人认为“阿波罗”登月计划不可能造假：首先因为该计划当时是在全球实况转播的，近亿人亲眼看到。另外，宇航员还从月球带回了一些实物，如岩石。
