The four stroke cycle

Part of Lesson Plan: Ingredients to Internal Combustion (updated) by Thomas Dougherty

Activity Overview / Details

An animation of a running engine will be projected on the screen at the front of the room along with the question, "How Does It Work?"

There will be a handout depicting the four strokes of the four stroke cycle at each seat and a cutaway single cylinder engine on each of the six tables in the room.  Students are in groups of four at each table.  As my computers, projection screen and white board are all on different walls, I am constantly moving about the room, even when I am lecturing. 

There are foam boards on the fourth wall with the students names color coordinated to their groups.  As students demonstrate proficiency at a task they are given a sticker to place next to their name.  This promotes a healthy competition and provides grading at a glance.  Using a wireless remote (or by asking me), students will be able to speed up, slow down or stop the animation at any point in the cycle.
