This computer visualization activity is designed to help upper division undergraduate students visualize the trajectories of a hockey puck moving along the surface of the earth.

Students work in small groups and use a computer simulation to model the motion of a hockey puck moving on the surface of the earth, taking into account the rotation of the earth.

The whole class wrap-up discussion highlights the possible trajectories a hockey puck can take, exemplifying the motion of the puck in different reference frames.
