At-home STEM Activities: DIY Kaleidoscope

We’ve all witnessed the reflection of light. Looking at ourselves in the mirror, seeing sunlight bounce off a pool of water, observing the moon—all of these occur because light is reflecting off of a surface. Light always reflects in the same way, following the Law of Reflection. Basically, the law of reflection says that when light hits a flat mirror, it will reflect at the same angle that it hits the mirror. We can use this law to manipulate light to make beautiful images inside a kaleidoscope! Let’s use some recycled material to make our own kaleidoscopes.
