Dear students, Thanks for being good for the sub today. There are a few things I'd like for you to do while I am out. First of all, I'd like you to watch the following videos. They are a bit more "current" than Abbott and Costello. Watch the three videos, and then answer the questions at the bottom of this page. You will be graded on your completion of the questionnaire. Have a good day, I'll see you on Friday.
