1、 创建绿色生态文明校园 xx班 主题班会活动时间:2014年x月xx4日 教学目标1.使学生了解垃圾的危害，增强环保意识。2.通过写处理垃圾的方案，培养学生的创新能力和想象能力。3.通过本节课，培养学生的动手实践的能力和参与社会生活的意识。课前准备1.让学生了解自己家里每天会产生多少垃圾，以及社会上人们是如何处理垃圾的。2.收集有关的图片、资料和数据。教学过程：一、导入(世界环境日入手，引出环境问题最突出的就是垃圾。)1.出示地球图片：我们只有一个地球，但地球的每个角落都散布着垃圾，就连蔚蓝色的海洋也受到了垃圾的污染。2.贴上“垃圾”两字，并请学生汇报搜集到的城市日产垃圾情况.广州市日产垃圾多

2、少？广州市日产垃圾4300 吨！且每年以 6.65% 的速度增长。“一吨垃圾等于一克黄金”，即城市每处理一吨垃圾的费用大约为 110 元人民币,有关人士预测，5 年后，广州的生活垃圾将达到 220 万吨/年，现在的填埋场将被填满。北京每年产生多少垃圾？北京市 18 个郊区县目前全年产生垃圾 490 万吨，其中 8 个城近郊区年产位圾 428.7 万吨，这其中 4 个城区，即东城、西城、崇文、宣武年产垃圾 177.8 万吨；仅东城、西城两城区每年就产出 105 万吨垃圾，占地 2 公顷，利用 37 辆车运输。3.据报道，目前，我国人均垃圾产量 440 公斤，已经高于人均粮食产量。现有城市近 70

3、0 座，生活垃圾日产 1 亿吨，每年以 810% 的速度递增着，2/3 的城市被垃圾带包围，存放量高达 66 亿吨。将有 200 多座陷入垃圾的包围之中。全球每年产生450亿垃圾，这是一个大问题啊！垃圾包围城市怎么办？4.贴上“怎么办”：今天老师要和大家一起来研究关于垃圾的一些内容。二、研究关于垃圾的一些内容城市垃圾有哪些?(请生汇报)食品垃圾：指人们在买卖、储藏、加工、食用各种食品的过程中所产生的垃圾。这类垃圾腐蚀性强、分解速度快，并会散发恶臭。普通垃圾：包括废弃纸制品、废塑料、破布及各种纺织品、废橡胶、破皮革制品、废木材及木制品、碎玻璃、废金属制品和尘土等。普通垃圾和食品垃圾是城市垃圾中可

4、回收利用的主要对象。建筑垃圾：包括泥土、石块、混凝土块、碎砖、废木材、废管道及电器废料等。这类垃圾一般由建设单位自行处理，但也有相当数量的建筑垃圾进入城市垃圾中。清扫垃圾：包括公共垃圾箱中的废弃物、公共场所的清扫物、路面损坏后的废物等。危险垃圾：包括干电池、日光灯管、温度计等各种化学和生物危险品，易燃易爆物品以及含放射性物的废物。这类垃圾一般不能混入普通垃圾桶中。三、研究如何减少垃圾的产出（说一说）1.出示算式：180000户家庭 1千克/户=180000千克=180吨“用数学的方法想想，怎么样才能使总的垃圾量变小？”2、“减少每户人家的垃圾产出就可以减少总的垃圾量，老师希望同学们能落实到自己

5、的行动中。你们还有没有办法能减少垃圾的产出？”3.小组讨论交流4.全班交流：四、研究如何处理垃圾（写一写）1.学生小组研究，教师巡回指导。分工：一人负责写，其余出主意。2.全班交流，说说方案的内容。3.根据学生的回答，教师随机补充：垃圾是放错了地方的财富a、垃圾中有可以利用的、不可利用的，最好能分类，设计分类的垃圾箱。可回收垃圾箱、废弃物箱有机垃圾（餐余废弃物）、无机垃圾（可再生废弃物、可回收垃圾）、有害垃圾（危险废弃物）b、可利用的垃圾要回收，充分利用。（五大类：废纸、塑料、玻璃、金属、布料）废纸再生纸塑料再生汽油（以聚丙烯为主料的不发泡塑料餐具）五、试一试1.“刚才我们每个小组都写好了垃圾

6、处理的方案，你们想不想让更多的人了解你们的方案呢？那我们该怎么做？你想通过什么方式做宣传呢？接下来就请同学们发挥集体的智慧，用自己喜欢的方式来宣传你们组的方案，让更多的人来关注垃圾的处理。”2.学生活动，教师指导（联系实际，制定创建绿色生态校园方案）。nbycudxqa7fhyi2chhi92tgkqcwa3ptgshls50clmtwn60eo8wgqv7xav2ohum32wgeauwydiawgmer4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgz7r4i30ka1dkagtgkqcwa3p tgz7r4i30ka1dkaghn3xt
