7.  Class 1  Class 1A  Class 2  Class 3A  Class 3B  Class 4

9.  Basic interest in the technology  Most likely spurred from laser pointers

10.  Build a simple 200mw laser  Write paper about lasers  Conduct experiments with certain variables  Put together a display with test objects  Create a box/stand to safely display the laser for the showcase

11.  A 400mw laser that does not run  Laser paper

12.  All parts were ordered  Soldering  Went through 6 DVD drives/burners  Ordered final part (that did not work)  Tried another design  Got more parts  More soldering  Laser did not work  Ordered actual last part
