Dear Students,

I do pray that you are having a wonderful Thanksgiving holiday.  I want to remind you that although you have no official homework, your test on Work and Simple Machines will be Tuesday 30 November 2010.  I know that you all will do well as long as you study.  We have gone over everything on the test several times.  Make sure you know how to complete word problems, that is work on placing the correct value with the appropriate variable so that you can use the formulas properly.  Post any questions you have
