AG MECHANICS 3

POWER MECHANICS

SYLLABUS

 

Instructor: Mr. Quick

 

Supplies needed: Safety glasses w/Z87 rating, Coveralls, Striker, Notebook w/paper and pen or pencil. The items needed can be purchased from the school or privately.

 

Expectations and Grading: This is a work based class that will be graded on three areas. The first area is work performance (60%), which means test scores, lab scores, project performance (quality), and completion. The second area is attendance (25%), which means coming to class on time, prepared, and making up absences. The third area is your daily log (15%). The log will be graded on completeness and accuracy. For example, you must have dates and time spent on each project in your log book. You will also need a description of the work done, include tools and processes used.
