简介:影子阶段

关于:莱斯利蒸汽学习实验室是一家旨在通过参与和基于查询的探索研究新机会的中心。除了与莱斯利的合作之外,Goldowsky博士是校长......

一个皮影屏幕或皮影舞台可以用来讲故事,设置神秘或美丽的场景,提出皮影难题,并了解如何光的工作。

Shadow Stage was developed as part of the Light and Shadow Workshop, using basic tools -- mirrors, lenses, and flashlights -- as the basis for explorations that can help build an intuitive understanding of how light works. Designed for out-of-school-time educators, the workshop is easily adaptable to other educational settings. The activities also work well for remote learning, since most materials are readily available or can be supplied in a teaching kit.

供应品

  • 手电筒(使用的最佳手电筒有一个带有单个LED的手电筒,请参阅步骤4)
  • 一张纸(描图纸是理想的,但任何paper or translucent material can work)
  • 磁带
  • 剪刀
  • 2cereal boxes (or a cardboard box larger than the sheet of paper, or recycled cardboard)
  • 小家用物品,玩具等可用
  • Recycle cardboard and other materials as available
  • 可选:纸紧固件(用于铰接式皮影偶)

是安全的:不要直视手电筒。家用LED手电筒会造成暂时的视觉斑点。请勿使用大功率或“战术”手电筒或激光指针进行这些活动。

第一步:搭建影子舞台

有许多简单的方法来建立一个影子剧场(搜索或在网上)。下面是一个快速而简单的方法。任何材料都可以替代。这里的方法使用“背投屏幕”——光线和形状在半透明屏幕(一张纸)后面,阴影从屏幕的“正面”看。这种方法在大多数传统的皮影戏中都使用,但是如果你只是将阴影投射到墙上或其他表面上,下面的大多数活动也能起作用。

我们简单的影剧院有三个组成部分:支架、屏幕和光源。

第二步:支撑

两个麦片盒可以作为现成的支持,以支持您的屏幕。

Of course, you can also make supports out of recycled cardboard, or any number of other materials.

Alternatively, you can use a cardboard box. This approach is a little more work, but it will help block excess light if you cannot darken your room. Cut a hole in one side of the box, a bit smaller than a sheet of paper. Latter you will tape your screen over the hole and put your flashlight in the box, or cut a second hole for the flashlight if the box is too short.

第三步:屏幕

Use a sheet of tracing paper, and tape it to the cereal boxes (or other supports).

描图纸是非常半透明,所以它工作得很好,特别是如果你的手电筒不是很强。普通打印纸也可以。您也可以使用任何其他半透明织物或材料。大屏幕可能更适合木偶戏。

第四步:光源

There are a few considerations in choosing a flashlight:

  • 最好使用带有单个LED的手电筒。这将产生一个单独的阴影。带有许多LED的手电筒会产生许多重叠的阴影——这是一个有趣的实验,但它们不会产生清晰的阴影。
  • Choose a flashlight with a switch that will keep it on.
  • 大多数手电筒具有镜头和/或反射器,设计用于形成聚焦光束。但是阴影的最佳光源是“点源”(没有镜子或镜头的单个小光源,使光的路径复杂化)。如果可以安全地进行,请拧下手电筒的前部并取出任何反射器或镜头,然后重新连接前面。

是安全的:如果您正在考虑拆卸手电筒的一部分,请确保您/参与者可以安全地进行拆卸,并且在取下镜头时可以避免将手指或其他物体放在手电筒的前面。不要与任何高电压、插入式或您不了解其工作原理的灯一起工作。请勿触摸手电筒内的LED或电线。如果您对手电筒的安全性有任何疑问,请不要拆卸手电筒,因为大多数手电筒在这些活动中仍能正常工作。

把手电筒放在屏幕上,当你把手放在手电筒和屏幕之间时,你会看到屏幕上有阴影。

你可能想用硬纸板做一个架子,把手电筒放在适当的地方。

你也可以尝试使用其他电池供电的光源,例如,万圣节杰克灯的LED灯,或LED蜡烛。

Step 5: Using Your Shadow Theater

There are many ways to use your shadow theater, and all of them can let you experience different aspects of how light works. The steps that follow outline some ideas and the resources section has links to more.

A good starting point is to create a scene: experiment with placing small objects between the flashlight and screen to create an interesting shadow picture. It could be realistic or abstract.

一些材料尝试:小食品罐,任何种类的回收材料,切割卫生纸管,面食,纱线,建筑玩具,雕像,动作人物,发刷,粘土创作,蓬蓬,你的名字!

opaqueobject will make a complete shadow stopping all the light coming from the flashlight before it reaches the screen. (See the glossary in the Light and Shadow workshop for definitions ofitalicizedterms.)

如果你使用半透明的or透明的材料?尝试使用仅阻挡部分灯光的对象的部分阴影。

对象折射光线可以在明亮的线条(光线集中的地方)和较暗的区域形成有趣的图案,在这些区域光线被部分阻挡或折射离开该区域。

第六步:阴影拼图

阴影将我们从颜色、纹理和距离感知中获得的所有信息剥离,只留下基本形状。更重要的是,我们只从一个角度看物体。这会带来一些好的阴影之谜。

  • Find an everyday object and place it between the flashlight and screen. Have someone else try to guess what it is just from the shadow. Can you find objects that are hard to guess? If the person can’t guess, you can give them a clue by turning the object and giving them a different perspective.
  • Try using two objects -- by combining their shapes on the shadow screen you can make harder puzzles.
  • 如果你把一个物体移到比另一个更靠近光线的地方会发生什么?你能定位两个不同大小的物体使它们的阴影大小相同吗?你能解释为什么阴影会变大吗(请记住,光线以直线传播,从手电筒开始,然后从手电筒向外扩散。)
  • You can also experiment with leaving the object still and moving the light. What happens to the shadow? Can you explain why the shadow changes? Similar things happen to our shadows as the sun moves across the sky. (See resources for outdoor shadow activities.)

Step 7: Shadow Puppets

来自世界各地的影子傀儡传统。您可以在基本设计的赋予指令上搜索暗影傀儡,您可以从与您的小组相关的特定文化中的传统研究网络。(维基百科有很多信息https://en.wikipedia.org/wiki/Shadow_playand many other sites.)

安y simple cutout can work as a shadow puppet -- cut your puppet shape from thin cardboard (a cut-up cereal box for example). You can leave a cardboard “handle”, or attach another way to hold it and make it move, for example, a coffee stir stick, chopstick or paper straw.

You can also use paper fasteners to make articulated shadow puppets.

Some traditional shadow puppets have translucent colored sections that allow some light through and create a color image as opposed to a solid shadow.

你不需要做一个逼真的木偶。你可以拿任何一件小东西,用它做一些有趣的影子——它们是暗示个性还是性格?阿瑟·甘森,一位动力学雕塑家,谈到通过运动使物体充满活力。你能把一个无生命的物体“复活”在你的影子屏幕上吗?

你可能想建一个更大的皮影剧院来演木偶戏。

第8步:资源金宝博比分直播手机版

Research shadow puppet traditions from specific cultures relevant to your group. There is lots of information in Wikipediahttps://en.wikipedia.org/wiki/Shadow_playand in many other sites.

许多艺术家用阴影创造出令人惊奇的艺术品。搜索皮影雕塑orShadow Art在里面Instructables or on the web. Many photographers have also found inspiring shadows to photograph.

If you are creating a drawing, painting, or animation, adding shadows can help add dimensionality, information about where the light is coming from, and even the time of day and the quality of the light. Looking at shadows in art:
