make a kaleidoscope and make a presentation in the class about how it works and diagram
Answers
Answer:
Many of you have probably played with a kaleidoscope. It is a tube that you hold up to your eye. You point the tube toward light and then slowly turn it. As you turn the tube you can see patterns of colors at the other end of the tube. A kaleidoscope works by reflecting light.
Light travels in a straight line. When light bumps into something it changes direction. If light bumps into something shiny it reflects back in the direction it came from. Think of light like a bouning ball. In a kaleidoscope there are shiny surfaces.
If you make your own kaleidoscope you can use mirrors or aluminum foil. When you point the kaleidscope toward light, the light enters the kaleidoscope and reflects back and forth between the shiny surfaces inside the kaleidoscope. Since you have filled the end of the kaleidoscope with little shiny objects, the light bounces off those too and makes the interesting patterns of color. As you turn the kaleidoscope the little shiny objects move which makes the patterns of color move.
Explanation:
Paste the three mirror pieces (from back side) on the cardboard which you have cut of the size of the mirrors itself. Place the three mirrors together in a way that they form a Triangular Prism. Remember that the reflecting part should be inside. Glue them together or use tape for binding them together.
