    高三（5）教室
    1、培养学生的爱国主义精神
    2、提高学生环保意识，改变不良生活习惯
    3、让学生意识到保护环境，从自己做起，从身边的小事做起。
    我校是“绿色学校”，我们发现部分同学的环境意识淡泊，不良的卫生习惯和破坏校园环境卫生的情况还屡屡出现。希望通过此次班会，唤起全体同学对环境教育重要性的认识，增强环境保护意识，自觉得爱护环境、保护环境，切实地从身边的小事做起，创设一个干净整洁的教室环境。此外，希望通过这次活动能够展示同学的才能，锻炼同学的组织能力，增进相互间的了解，并培养相互间的协作意识。
    同学们，大家都知道，如今在世界范围内荒漠化日趋严重，地球环境是越来越恶劣。环境保护已是当今人类社会一个沉重的话题。今天，就让我们重提这个话题，加强对环保的认识，从我们身边的小事做起，自觉主动地去保护校园绿化，美化校园环境，做文明中学生。
    展示环境污染图片
    1、展示从卫星中拍摄到我国地貌的图片。问：你们从图片上发现了什么？
    2、利用多媒体向同学展示一些比较突出和严重的环境污染问题（如：水污染，大气污染，土地污染等）。请同学们列举我们生活中，哪些行为会造成环境污染。同学分组讨论一下在自己身上哪些不文明行为是需要改进的？我们如何来保护身边的环境？
    1、 小组代表发言
    生1：要做到人走灯熄，电扇停，不浪费资源。
    生2：见到垃圾随时捡。
    生3：不随地吐痰，注意个人卫生。
    生4：每个人都要管好自己的“小天地”。
    生5：卫生角应该保持干净、整洁。
    生6：值日生应尽好自己的义务，做到一日三扫。
    生7：同学之间互相监督，勇敢阻止破坏环境的行为。
    生8：加强环保意识。
    生9：班级制订班级卫生公约，对破坏环境的行为进行处罚，对保护环境的同学进行奖励。
    2、主持人对于发言进行小结
    3、 环保知识抢答
    主持人：那么大家是否关注环保，对于环保知识知多少呢？就让我来考考大家吧。下面以小组为单位进行环保知识抢答。（穿插脑筋急转弯题，以提高趣味性。
    介绍竞赛规则：
    （1） 全体学生总共分为四组。以小组比赛的形式进行。
    （2） 整个比赛分为必答题和抢答题两部分，每题分值均为十分，答对加十分，答错倒扣十分。
    2、比赛开始：
    3、宣布比赛结果，并对这次比赛进行 总结 初级经济法重点总结下载党员个人总结TXt高中句型全总结.doc高中句型全总结.doc理论力学知识点总结pdf 。
    环境污染和生态破坏的发生，不仅是因为不合理的生产方式，也与我们每一个人的生活密切相关。比如，如果我们少用甚至不用塑料袋，那么塑料袋生产厂家就会倒闭，白色污染就会消失；如果我们不购买那些高级高油耗的汽车，厂家就会被迫生产低油耗、高性能的汽车，尾气污染就逐渐减少；如果我们每天节约一杯水，少乘一次电梯，都会对环境的改善做出一点贡献……
    同学们，让我们行动起来吧！地球家园的美好未来，就掌握在我们每个人的手中；行动起来吧！我们会建出绿色家园、绿色学校；行动起来吧！我们会变得更加纯洁、更加高尚、更加有品味！从现在做起，从身边做起，保护自己美丽的家园，美丽的地球，增强了同学们的环境保护意识，从各自的内心发出“我们要共同保护环境”的心声。
    通过此次班会，同学们都意识到了平时没注意到的生活小细节，认识到只有共同创设一个良好的环境，才能更好地学习和生活。美好的校园环境，人人有责。环保并不遥远，我们可以从身边的小事做起。同时，作为一个中学生，也要宣传环保，让身边的亲朋好友环保意识进一步加强。

    知道噪声产生的原因和途径。
    知道噪声对人类有哪些危害。
    知道减少噪声有那些措施。
    噪声产生的原因。
    1、导入同学们，我们的生活离不开声音，各种各样的声音使世界充满生机，使我们的生活丰富多彩。美妙的乐声给人们带来了无穷的欢乐和享受。但是，刺耳的噪声却严重危害着人类的健康。揭题——噪声与人类健康。
    2、新授
    （1）噪声引起的危害有哪些？
    它引起头痛、心慌、全身乏力、听力受损，还有心血管系统、神经系统、消化系统等方面的疾病，甚至导致胎儿畸形。噪声已经成为世界第一公害，被称为“无形杀手”。
    （2）噪声是怎样产生的呢？
    噪声的产生主要分为交通噪声、工业噪声、建筑噪声和生活噪声。
    机动车辆、飞机、火车和轮船等交通工具在运行时发出的声音，称为交通噪声。其中飞机的噪声最大。
    （3）工业噪声是指工矿企业在生产过程中因机械振动、摩擦、撞击以及气流振动而产生的嘈杂声音。工业噪声主要来自机器和高速设备。
    （4）建筑工地上要使用各种动力机械，要进行挖掘、打夯、搅拌和运输材料设备，也会产生大量噪声，称为建筑噪声。
    （5）生活噪声是街道、商场、文化娱乐场所（如电影院、剧院、体育场）以及建筑物内各种人群活动及生活设施所产生的声音。
    （6）噪声的强弱大小是用“分贝”来表示的。分贝数越小表示环境越安静。我们通常谈话的声音是30—40分贝。
    当噪声超过85分贝，长期可使听力受损，超过120分贝，听力较快受损，甚至耳聋。
    3、小结。
    为了有一个安静、舒适的环境，我们必须设法制服噪声这个“都市罪犯”。我国已经颁布事实了《中华人民共和国环境噪声污染防止法》，加强了噪声的管理和防治。同学们，让我们一起努力，制服噪声这个“恶魔”，使我们的家园更安宁！
    4、作业。
    （1）调查你所在地区的噪声的怎样产生的？
    （2）调查你所在地区为减少噪声采取了哪些措施？
    （3）开一个讨论会，谈谈你对减少噪声的看法。

    随着人们生活水平的提高,家长常常忽视或放弃一些常见的物质资源,而花钱去给孩子添置各类益智玩具、运动器械。其实,生活中常见的一些东西往往蕴含着丰富的教育价值,报纸就是其中的一种。
    对于我班的孩子来说，他们都已具备独特的审美能力。本次活动我将报纸与服装相结合，特设计了这节美工活动：《我是环保服装设计师》。
    让孩子自由选择自己喜欢的装饰材料来设计衣服，锻炼幼儿小肌肉的活动能力，体验制作环保服装的乐趣，增强环保意识。
    1.观察环保服装，了解环保服装的装饰材料。
    2.学习两人合作，利用废旧报纸，运用剪、粘、折、拼接等方法设计、制作服装。
    3.体验制作环保服装的乐趣，增强环保意识。
    观察环保服装，了解环保服装的装饰材料。
    学习两人合作，利用废旧报纸，运用剪、粘、折、拼接等方法设计、制作服装。
    知识经验准备：
    观察生活中的人们的服装，积累一定的生活经验，并收集废旧的`报纸。
    物质材料准备：
    1.课件一份。
    2.剪子、胶水、双面胶、勾线笔。
    3.各种废旧材料：信封、报纸一捆、皱纹纸、塑料袋等。
    4.时装表演的音乐、轻音乐。
    5.教师事先用废旧材料制作的服饰样品2件。
    一、观看书信内容，导入教学活动
    1.今天，老师收到一封信和一捆废旧报纸，是森林的动物朋友们寄来的。我们来看看信中写了些吧！
    2.上面写着：一年一度的森林环保服装展的日子将要来临，请大四班小朋友们参加。小朋友想参加吗？（想）那我们就来当回环保服装设计师，设计服装好不好？（好）
    二、教师示范操作，幼儿创作服装
    1.教师出示作品
    老师已经设计了一套环保服装，我们来欣赏一下吧！
    2.提问:这件服装用了哪些材料？你们喜欢老师制作的环保服装吗？
    教师小结：报纸做的衣服、皱纹纸围的花边、彩色纸剪成的花等。杨老师也
    非常喜欢这些报纸做的漂亮的衣服。（观看课件：瞧，蒋老师穿上了杨老师做的
    环保衣，多神气。）
    3.教师示范讲解
    现在让我们来看看，这件衣服的制作方法，这件环保衣，最主要的材料就是废旧报纸。
    首先，我们要把报纸对折，有折痕的一头朝上，剪出一个领口。
    然后，将自己想好的衣服轮廓在报纸的正面画出来，然后用剪刀沿着轮廓线剪下来。
    最后，在再剪好的衣服上剪贴上彩色的皱纹纸花边和彩色纸做的花，让废旧报纸做成的环保衣更美丽。
    三、教师提出要求，幼儿想象操作
    1.在制作时，两个小朋友合作进行，一位可以扮成设计师，一位可以扮成模特儿穿上环保衣。不要争抢，一起合作完成。
    2.在使用剪刀时注意安全。
    （注意：幼儿操作时播放轻音乐）
    四、幼儿评价服装，走秀展示服装
    1.幼儿穿上衣服，提问：
    （1）你做得是什么服装?
    2.由森林里举办的“森林环保服装展”，马上就要开始了，小动物们已经坐在了前方的评委席中（出示课件小动物们观看的场景），让我们一起随着音乐展示一下我们设计的服装（模特儿与设计师一起走秀），向森林里的所有动物朋友们宣传环保知识，好吗！
