Frank T. Wheeler Elementary School fourth graders showcased their innovation, creativity and problem solving skills at their “Invention Convention” held on March 14th. As part of their studies about how things work, what problems they solve, and how they could be improved, the fourth graders were tasked with looking for a problem to solve with an “invention” as the solution. They presented their unique inventions to family members, staff and student peers during the annual Invention Convention event.
