1、幼儿园小班美术活动设计物体画-气泡变大1.学习玩小鱼吐气泡的游戏，并发现从小到大的变化。2.通过观察颜料滴在不同材料上逐渐变大的过程，可以感觉到点的大小。3.体验在不同材料上绘画的乐趣。活动准备1.用小勺子或塑料滴管装饰小鱼胸。2，每套三种颜色的水彩颜料，一套宣纸，一套白色棉布。教师应注意水和色素的比例。很容易突出颜料在宣纸和棉布上的效果。如果没有水彩，则可以用水粉代替，然后添加更多的水。提供给幼儿的颜料最好着色，并与对比色匹配。活动程序1.老师将魔术变成了“鱼妈妈”的角色，并赠送了一把勺子，激发了孩子的好奇心。老师：小鱼宝宝，今天妈妈想给你个魔术。看！母亲的零钱是什么？2，老师用小汤匙画画，

2、在将纸上的颜料倒入故事的过程中，边讲边讲。老师：妈妈很高兴看到小池塘变得如此美丽！游泳，喝口水，吐气泡。重点提示当老师演讲时，语言和相应的动作会结合在一起。例如，喝一口水-舀颜料，吐气泡-将油漆倒在纸上。教师使用有节奏的语言进行讲解，语调大声，说话速度减慢，使孩子注意操作方法，易于学习和掌握。3.鼓励幼儿大胆猜测纸上“鱼妈妈吹泡泡”的变化。老师：请猜，鱼妈妈吹出的小气泡会怎样？在图4中，孩子玩着玩宝宝的“泡泡”游戏，感觉从小到大的变化很小。（1）老师帮助孩子回忆起鱼妈妈吹泡泡的方法。（2）孩子进行手术并玩“鱼宝宝”吹泡泡游戏。（3）在儿童操作过程中，老师指导儿童以惊讶的语气观察屏幕上色素滴的变

3、化，发现并说气泡变大。老师：鱼宝宝，看看，气泡是什么？尝试一些泡泡，然后再试一次，看看会发生什么变化。5.欣赏并想象“鱼宝宝”吹出的气泡。师：鱼宝宝吹的泡泡有什么区别？什么？活动建议活动婷神提供不同大小的铅纸，水粉，汤匙或滴管，以引导儿童观察水粉颜料如何在铅纸上掉落。角落活动1艺术区：提供小鱼，小蜻蜓，小螃蟹等的背景图片。孩子们可以用水粉笔或油画棒添加气泡。 2语言区：提供小气泡，小蟑螂等的图片，孩子们用短语“越来越大”练习观看图片。 3数学区域：提供不同大小的光盘，以按照大小顺序引导孩子。创造环境将儿童作品布置在展览区中，以引导儿童感受并比较颜料在不同材料上留下的不同痕迹。在家上学1指导孩子
