【选题缘由】目前,全国有不少地方正推行对废旧电池的回收工作,但效果不佳,其主要原因是人们普遍缺乏对废旧电池污染的认识。如果能利用简易的方法让人们直接感受到废旧电池污染的严重性,那么人们便会自觉地配合,搞好对废旧电池的回收。目前,我们对废旧电池的处理还缺乏足够的技术支持,根据某些水生植物能吸收一定重金属物质的原理,尝试用水生植物净化被废旧电池污染的水体,有一定的可行性。【本实验对应章节】人教版高中地理(必修)第三单元:陆地和海洋中陆地水和水循环;人类面临的全球性环境问题与可持续发展8.1、8.2“活动”。鲁教版高中地理(必修)第一册第二单元:从地球圈层看地理环境之水圈与水循环。中国地图版高中地理(必修)上册第三篇水圈等。【实验目标】(1)通过在饲养金鱼的鱼缸里加入不同种类、型号和数量
【】 【Why the title of the topic At present, there are many places in the country are implementing the recycling of used batteries, but the effect is not good, the main reason is that people generally lack awareness of waste battery pollution. If we can use simple methods to let people directly feel the seriousness of waste battery pollution, then people will consciously cooperate with and do a good job recycling of used batteries. At present, we still do not have sufficient technical support for the disposal of used batteries. According to the principle that some aquatic plants can absorb some heavy metal substances, it is feasible to try to use aquatic plants to purify the water polluted by used batteries. 【Chapter Correspondence】 People’s Education Edition High School Geography (Compulsory) Unit 3: Terrestrial Water and Water Cycle in Land and Oceans; Global Environmental Issues and Sustainable Development for Humankind 8.1, 8.2 “Activities”.
