Week of 9/14-9/18

One of the many things I learned this week was that light from a laser travels in straight lines. I found this out by clapping erasers over the path of the laser . The path then became visible. I also learned that we cannot see without light. I tested this by going under Mr. Finley's desk where it was completely dark. There was a sign attached to the curtain. I could not read it or even see any of it due to that fact that there was no light. This proved that us humans need light to see. I also learned that we need our eyes and an object to see because the light bounces off the object into our eyes. I was also trying to see if light from a light bulb travles in all different directions but my partner and I couldn't really tell. All of this information that I learned is important to know because if I ever need to know the way the light travels I know that it travles in straight lines.
