1、学习好资料欢迎下载幼儿园大班科学课教案有趣的泡泡活动背景：晨间活动时，小宇航带来了一个吹泡泡的玩具。于是我们玩起了吹泡泡的游戏。看着孩子们兴奋得叫着、跑着，追逐着五颜六色的泡泡，我的心情也随之跳跃起来。于是一场关于泡泡的活动方案悄悄酝酿起来。活动目标：1、了解泡泡的特性，学会制作泡泡水，知道无论什么形状的管子吹出来的泡泡都是圆泡泡，感知空气与泡泡形成之间的关系。2、培养幼儿对科学小实验和科学探索的兴趣，体验同伴间交流、协作的快乐及创造的乐趣。活动准备：糖、盐、洗衣粉、肥皂、洗洁精、一次性杯子、粗中细三种型号吸管、硬纸板制成的三角形管子、正方形管子、梯形管子、水等人手一份，笔、纸若干。活动过程：

2、一、游戏抓泡泡导入，了解泡泡的特性1、教师出示吹泡泡玩具，带幼儿玩抓泡泡游戏。2、结束游戏，师幼谈话。刚才抓泡泡时你们的心情怎样？有什么感受？你们看到的泡泡是什么样子的？抓泡泡时发现泡泡有哪些变化？二、制泡泡水学习好资料欢迎下载1、提问：（1）哪些材料可以制作成泡泡水呢？幼：洗洁精、糖、盐、肥皂、洗衣粉。（2）这些材料是不是都能制成泡泡水呢？现在我们就来试一试看吧。2、幼儿做实验，并做好记录，教师观察引导。材料结果糖盐洗衣粉肥皂洗洁精3、请幼儿说说实验中的发现洗衣粉、肥皂、洗洁精这些洗涤用品可制成泡泡水洗衣粉等兑少了也吹不成泡泡。沾泡泡水时要充分，不能用太大力吹，不能吹得太快，否则也吹不起来。

3、三、用不同形状的管子吹泡泡（圆形、三角形、正方形、梯形）1、出示各种形状的管子，请幼儿说出各是什么形状。2、教师抛出问题：圆形管可以吹出圆泡泡，那三角形的管子会不会文档编码:CU8S1X4K9E1 HI5K5A5Q2Z7 ZM10Q5L1Y7O3文档编码:CU8S1X4K9E1 HI5K5A5Q2Z7 ZM10Q5L1Y7O3文档编码:CU8S1X4K9E1 HI5K5A5Q2Z7 ZM10Q5L1Y7O3文档编码:CU8S1X4K9E1 HI5K5A5Q2Z7 ZM10Q5L1Y7O3文档编码:CU8S1X4K9E1 HI5K5A5Q2Z7 ZM10Q5L1Y7O3文档编码:CU8S1X4K

10、的泡泡呢？3、幼儿做实验。4、请小组代表说说实验结果。5 教师：无论什么形状的管子吹出的泡泡都是圆泡泡。四、吹奇特泡泡1、刚才大家吹的泡泡都是一个一个、单一的，现在请小朋友开动小脑筋，看看谁能吹出奇特的泡泡？2、幼儿探索吹奇特泡泡两根吸管合二为一吹泡泡。四根吸管合在一起吹葡萄串泡泡。细吸管外套粗吸管吹泡泡。在桌面上吹半球形泡泡。五名幼儿在桌面上合吹泡泡花。五、说泡泡-不用嘴吹的泡泡师：刚才我们都是用嘴巴在吹泡泡，你在生活中还见过哪些泡泡？六、活动延伸：画泡泡教学反思：没想到一个小小的转瞬即逝的泡泡，竟给孩子们带来了如此多的乐趣！从一开始抓泡泡，到制作泡泡水，到用不同形状的管子吹泡泡，文档编码:
