This lesson will help students understand what the Coriolis force is, and what effects it has on objects in motion. Students will be able to describe and explain the Coriolis force, and compare and contrast conditions under which the Coriolis force has a significant impact on objects in motion with conditions under which the influence of the Coriolis force is negligible. Portions of this lesson are based on a webpage called "Bad Coriolis", a resource devoted to correcting misconceptions about the Coriolis force and other natural phenomena.
