Focus Question: Where and how are forces applied in
a complex machine?
The teacher will set up
several numbered stations with one complex machine per station (e.g., egg
beater, pencil sharpener, bicycle, stapler). Students will be assigned a
number that directs them to a station. Student groups will discuss the
force applied and the direction of that force. They then will draw a
diagram of their item that illustrates both the force and direction of
application as well as the resulting motion. Each group will explain its
diagram to the class.
