Period 2

Today in class we discussed the question, Is the direction light is moving important? So as our hypothesis we decided that light travels in a straight line. Also make sure that when your taking about light you don' say that it goes in a line because a line could wiggle and curve and do all of that good stuff, but light goes in a straight line. We also drew pictures in class today in these pictures To show the light and what direction it was going we used an arrow.

In the diagrams we drew answers to the question Why can we see light? The first picture we came up with is the picture on the top left. That picture shows the laser's light beam coming from the laser and going to the wall. Once it hits the wall the light reflects off the wall and all around the room and in this case it hits the person's eye so then he could see it. So after that we wanted to draw a picture that described how we could see the laser's beam before it reached the wall. That picture is under the top picture.In that picture it shows that when the laser is traveling through the flour cloud it would hit some of the flour particles and then it would reflect off of them and into your eye.

So to conclude our class discussion we did an experiment to see if light reflects in every direction. Our hypothesis was that the light would reflect off the object and hit something else aslong as it had enough power to make it there. During the experiment I shined the lazers at one object that was positioned close to another. When I shined the laser at the object it did reflect off the first object and hit the second. Some of the things I did were that I shined the laser at my paper and it reflected off of that and hit the wall, I shined the laser on my hand and it reflected and hit the poster. I also shined it on the poster and it hit the ceiling.

So at the end of the experiment I concluded that light does reflect off the first object it made contact with and if it has enough power it will hit another object.
