Power Mechanics 1


Department of Industrial Technology


Forest Lake Senior High


Course Outline – Power Mechanics I


Course Description: 

Introduction to Power is offered to any student in grades 10 through 12.  It will cover all types of internal combustion engines with emphasis on the smaller two and four-cycle engines.  Laboratory time will be devoted to disassembly, examination, reconditioning and assembly of these engines.  As time permits, other areas in Power Mechanics will be explored. This course is a prerequisite to Power Mechanics II and Auto Technology.
