周五上午，老师妈妈带我们到三楼舞蹈厅做了一个有趣的游戏——“脱鞋跳舞”。音乐响起，大家随着欢快的乐曲结伴舞蹈起来，一只脚穿鞋、一只脚穿袜子，感受大不一样（一只脚滑，一只脚不滑），好玩极了！但当我们将穿袜子的脚穿上鞋跳舞时，奇怪~~~~脚不滑呢！为了让大家探究出个所以然，老师妈妈引导我们对鞋底进行了观察，在小朋友们你一言我一语的交谈中，大家明白了：穿袜子跳舞感觉脚滑，是因为袜子光滑的原因；穿鞋跳舞不滑，是因为鞋底有花纹、有凹凸线条……，花纹、线条会增加鞋子和地面的摩擦力，可以防滑。有了这些发现，大家的探索兴趣更浓呢！开始有了寻找生活中光滑、粗糙及能产生摩擦力的物体的兴趣来了，跟我们一起去看看吧~~~~~~]
