Period 1 - Laser Pointer

Today in class we are discussing what characteristic allows us to see things. We used laser pointers to help us figure these things out. The sun rays reflect off of you then bounce off into the lake or river. Then you see you reflection in the lake. These ideas are very important because they help us learn how you see things and how they reflect.


We also discussed the homework and realized the more light the smaller you pupil gets and the less light the bigger the pupil gets. We soon realized that many of our ideas were too complicated and we erased them. We decided that we could test the rest of our ideas. Then we found out that your eye could only take in so much light so when you look right at the sun that is why your eyes hurt. Mr. Finley brought up an idea about how much light do you think would come out of a little spot.


Below, there is a picture of a laser pointer. We used these during class to do experiments and make hypothesis and predictions. These also helped us figure out how light works and why we can't see the rays that travel in between the light source and the wall. I would have to say that if we didn't have those i would be pretty lost in most of the work we do in class.


Some confusing points in class we when we had class discussion. Although it helped sometimes it was a little hard to figure out what other people were explaining their ideas. When doing those you really have to listen and think outside of the box to understand what other class mates are talking about. I really think that was the only thing super confusing.
