Representatives from Vectren Energy Corporation discussed electric and natural gas safety tips with the 4th graders at Evansville Day School.  The presentation included the "Energy Stick", which was used to demonstrate the concept of an open and closed electrical circuit. Students held on to the "Energy Stick," and if their bodies or objects they were holding completed a closed circuit, lights and noises would occur. They tried using different items such as metal, leaves, coal, and paper, to determine which were conductors (and made a closed circuit) and which items were insulators (and made an open circuit).
