The following activity is an activation assignment. This must be
completed online and e-mailed to your instructor before you may register in DL Physics 12. It
will be worth 5% of your total course mark. This assignment should take approximately two hours in
total. There are links to some recommended websites where you can learn the concepts as you complete
this assignment.You may wish to do a rough copy of your answers on paper, before completing the
online version. If you quit the program, it will be submitted automatically, even if you have not
finished, so be sure to complete all sections during the same time period and then
submit
