紧接着第一课时的话题,我们不仅要节约资源,更要懂得资源的再利用和循环使用,让学生打开思维说说生活中怎样进行资源的再利用。在学生阐述之前,教师用例子先做示范,引导学生大胆流畅地表达。待学生说了一些想法不能再说时,教师再出示图片让学生了解很多人眼中的废物可以是宝贝,激发学生上网搜索更多可以变废为宝的物品。最后,组织学生动手制作环保海报并做综合陈述,号召更多的人参与到保护地球的行列,明白我们只有一个地球,保护地球就是保护我们的家园,保护环境就是保护我们自己。家庭作业中要求学生在班级或小区做调查,了解资源的再利用和循环使用情况,并给当地政府部门写信呼吁更多的人们重视资源的再利用和循环使用,既锻炼学生的交往能力、表达能力,又能进一步树立学生的主人翁意识。4
