Campbellsburg Elementary kindergarteners engineered traps to capture the elusive leprechaun on Friday. Students, including Tucker Tingle and Xander Rahm, at left, who worked together, under the guidance of teacher Megan Hook, decided what materials to use, solved problems, worked together in teams and used creativity to make the traps. But when the students got to school Monday morning and checked the traps, no leprechauns were caught.
