Reflection, Refraction, & Defraction Lab Response

Last week, we did a little project where we had to complete a packet with about 10 stations. At these stations, either reflection, or refraction was shown. Some examples of the reflection stations are, at one of those stations, you would most likely have a mirror or obviously something to be reflected back into your eyes. At stations such as refraction, there might be something to do with a liquid, and how the light is bent through the liquid, or how the light travels through it... in this case, a strong and excellent example of refraction is when you put an item such as a pen in a half full cup of water. But you wouldn't see the pen where you expect it to be, because the light is refracted (bent) through the water to show you the image a little bit off of where the actual object is. It was quite interesting to learn about reflection, and refraction because you basically have seen it your whole life, but never knew why it happened or what it was.
