中班科学活动《各种各样的纸》教案与反思篇三

纸是我们生活中常见的物品。各种各样的纸对于幼儿来说既熟悉又陌生，他们随时随地能看到、用到纸，但这些纸的真正用途和特性，他们却是不了解的。《纲要》中指出：幼儿的科学活动应密切联系幼儿的实际生活，教师应充分利用幼儿身边的食物与现象作为科学探索的对象。因此我设计了本次教学活动，是幼儿对各种常见的纸的用途及特性有一定的了解。

1.认识常见的纸，了解其用途。

2.初步了解其特性。

3.激发幼儿对科学活动的兴趣。

重点：认识常见的纸，了解其用途。激发幼儿对科学活动的兴趣.

难点：初步了解其特性。

物质：

1.各种类型的纸。

2.一盆清水。

3.各种纸的ppt。

经验：提前了解各种纸的用途。

中班的孩子见过的纸已经是不少了，但是对于纸的认识仅仅只是知道这是纸，对于值得特性以及用途知道的是不多的，所以我设计了这次活动，主要为了让孩子们对于纸有更深一层的了解，对于纸的用途和简单的特性有一定的认识。另外中班孩子的自主探索能力有待加强，所以在活动中我让孩子通过实验，自己探索并说说纸的特性。

在第一环节中，我用谈话法，让幼儿说说对于纸的认识，引起幼儿兴趣，引出课题：各种各样的纸。在第二环节中，我出示ppt，运用观察法，让幼儿自己观察，并且帮助幼儿一起说一说图中纸的用途，这样就解决了本次活动的重点。第三环节中，我用实验法，让幼儿在自主的实验中习得纸的一些特性。最后一环节中让幼儿说一说他们手中的纸入水后出现的现象，从而解决了难点。

展示各种纸，提问：

1.看看老师是手上拿的是什么呀？

2.你们都见过这些纸吗？

3.有谁知道这些纸叫什么名字吗？

4.他们分别有什么用途？谁来说说看？

我们来看看老师图片上。

出示ppt，帮助幼儿一起说说每张图片上的纸是什么用途。

师：看看老师这里，谁来说说看这些纸有什么用途？可以干什么？

让幼儿每人拿一张纸，然后放入水中蘸一下，观察手中的纸有什么变化。

师：下面请小朋友们将自己手中的纸放到水中，看看会有什么现象，等一会告诉老师哦！

师：刚才小朋友拿的是哪一种纸？它放入水中后有什么现象？

中班科学活动《各种各样的纸》教案与反思篇四

1、 通过观察实验认识纸的种类和特性。

2、 通过分组活动、加深对纸的认识，培养幼儿的动手能力。

3、 教育幼儿爱惜纸张和书本。

1、 用多种纸制成的纸娃娃一个。

2、 vcd、碟片《造纸的过程》

3、 各种纸、固体胶

一、 简要了解纸的制造过程，导入活动

1， 出示数张纸，提问：这是什么？纸是用什么造出来的？怎么造的呢？你想不想知道？

2， 放vcd，引导幼儿观察，通过提问，让幼儿了解纸用树皮、植物的根、茎、叶等加工成的。

二、 认识纸的种类

1、 出示纸娃娃，教师以纸娃娃的口吻说话：“小朋友好，我是一个特别的娃娃，请你猜一猜，我是用什么作成的？摸一摸我身体的'各部分材料有什么不同？摸上去有什么感觉？找一找，你的盒子里有没有相同的材料。

2、 请幼儿看一看，摸一摸，找一找纸娃娃的各部分材料，启发幼儿把自己的发现告诉大家。

3、 幼儿讨论回答，师生小结，纸有多种多样的，它们颜色不同，厚薄不同，软硬不同。

三、 通过实验，认识纸的特性

1、 教师为幼儿提供材料

2、 幼儿分组实验，并思考，你发现了纸可以怎么样？

3、 引导幼儿运用多种方式，进行探索，轻声交流实验结果。

教师小结：纸具有易燃、易撕、易湿、易皱、可折、卷、体轻等特点。

四、 观察纸制品，了解纸的用途

1、 出示图书、扇子、包装盒等纸制品，告诉幼儿纸可以做成许许多多的物品。

2、 我们的生活离不开纸，启发幼儿说一说生活中还有哪些物品是用纸做的？纸可以做什么？教育幼儿爱惜纸张和书本。

五、

幼儿分组操作

教师为幼儿提供各类纸，提问：“你想用什么样的纸发明什么？它对我们的生活有什么用处？请你做一做，说一说。”
