🌈生活明朗⛅万物可爱🥰
不负每一份美好🍭✨
💡本周科学实验💡
《蓝海沉浮》、《彩虹雨》、《认识水》
扑捉一群小可爱👧🏻👧🏻
享受着玩中学的快乐🤗
身心愉悦✌🏻
👉🏻这才是真正的童年美好时光🌱


🧪大班科学活动:蓝海沉浮


🌡实验材料:白醋、色拉油、小苏打粉、蓝色色素、搅拌棒、透明杯子。










💡实验原理:醋酸遇到小苏打会产生化学反应生成大量气泡,拉着蓝色的醋酸液滴往上飘,到了油的表层,气体跑掉了就回落,然后到杯底再次反应,就有了反复沉浮的景象


🧪中班实验名称:彩虹🌈雨


🌡实验材料:清水、卫生纸、彩笔、白纸板、视频










💡实验原理:纸巾里有很多细小的棉纤维,这种棉纤维好像是小管道一样,水吸附在小管道内侧,由于力的作用就可以把彩虹的颜色推送到其他地方


🧪小班科学活动:认识水


🌡实验材料:不同颜色标识的透明杯子(里面分别装有凉开水、白糖水、食用白醋、牛奶)










💡实验原理:水是无色、无味的,水具有流动性等特征。


🎈科学小实验
✨科学可以启发幼儿的智慧 🧠
😎实验可以实现幼儿探索的欲望!
🥳好奇心成为激发幼儿动手动脑的动力💪🏻
让幼儿在探索中快乐成长💕
