The Week of October 12th

This week we continued our study on refraction and reflection in preparation for a science test.We made rubrics for ray and wave diagrams so in the future we know how to make them. That is a good reason for why we need to know this in life. Tests are a part of life. To get back to science we also had a science carnival where we went to different stations and observed things. Some stations included a drawing that we had to describe while other stations gave us scenarios that we had to analyze and decide which person in the scenario was right.
This week we also learned about how the eye works. To explain this i would tell you light bounces off an object and goes in every direction including the eye. But the rays that hit the bottom of the object only have room to go into the top of the pupil and the rays from the top of the object only have room to get into the bottom of the pupil. This almost directly compares with the flame turning upisdedown. Anyway once the rays go into your eye they cross eachother therefore displaying the object upsidedown in your eyes. But fortunately the brain flips the image displaying it rightside up.
Finally i learned about the densitys of certain objects. Glass is the most dense object. Water has medium density and air has the least density. When light travels from a less dense to more dense object is bends or refracts towards the normal line, but when it goes from a more dense to a less dense object it bends away from the normal line. In concluison that is what we did this week.
