What We Learned In Class This Week (:

1. In class this week we learned that all different surfaces have different levels of reflectiveness. For example water is more reflective than the table. We learned this by testing how reflective they were we shined the lazer on many different surfaces and then gave the reflectivness a rating of 1-5 and thats how we came to our conclusion. It is important to know this incase you are tyring to see your reflection in something you know wheather or not you will be able to see it.



2. Also in class this week I learned that if I shine a lazer at the mirror it will reflect back up at the same angle. We learned this by shining the lazer at a 30 degrees and measured the angle if reflected back at and it was 30 degrees. Then we did the same thing with 40 degrees and so on. It is important to know this because it is good to know that things will reflect off of a surface at the same angle they are shined at.



3. Finally in class this week I learned that light is made up of particles of light. Light moves at the speed of light and gos in staight lines. We learned this because Mr. Finley and Mr. Segan taught us this in class on Friday. It is important to know this because now I know what light is made up off and that could be useful.
