Investigation 4-1
Risk Perception


Students are asked to rank order the fifteen leading injury-related reasons why boys and girls visited emergency rooms.  Students then compare their perception of the risks with the actual risks and realize that their perceptions are not always the same as the actual risks.  Students then explore the impact that this difference might have on the allocation of resources to prevent visits to the emergency room for a particular reason.
