10、六、注意事项1 钟表嘀嗒声一定要明显，听得清楚。2给幼儿提供一个安静的环境，以便辨听。3听声音作比较时，幼儿要在同一位置和相同的距离去辨听。七、拓展思路1 在科学角里提供大量有关固体传播和空气传播的图片、记录卡及操作材料。2到大自然、社区、家庭去了解固体比空气更能传播声音，以及声音拢起来后可以放大声音的原理。文档编码:CL9O10U4A8C7 HJ1L9M4G9T10 ZL8X6I8C7V1文档编码:CL9O10U4A8C7 HJ1L9M4G9T10 ZL8X6I8C7V1文档编码:CL9O10U4A8C7 HJ1L9M4G9T10 ZL8X6I8C7V1文档编码:CL9O10U4A8C7 H
