What do you get when you combine hundreds of students who have boundless energy with hands-on science activities teaching them how to use energy efficiently?

You get The Dayton Power and Light Company (DP&L) and Vectren Energy Fair, on Friday, March 2 from 9:30 a.m. to 1:30 p.m. at the University of Dayton. This year's Energy Fair is bigger and better than ever, expanding to 12 rooms in the Kennedy Union for almost 500 students from all over the Miami Valley.

At the Energy Fair, facilitated by the Ohio Energy Project (OEP), high school students will teach younger students how energy is part of their everyday lives. The high school instructors are from Kettering-Fairmont, Oakwood, Eaton, Lehman Catholic, Clinton-Massie and West Carrollton. The younger students are in grades 4-7 from Kettering, Troy, Newton Local, Centerville, Clinton-Massie, Miami Valley School and Ascension in Kettering. They will learn about light, sound and heat.

Students will explore the Energy Carnival, ride the Energy Bike and conduct science experiments with exploration stations featuring ten new activities about light and color; refraction of light, states of matter; sound waves; sound and pitch, energy transformations; Ohio resources for energy; thermal energy; appliances and electricity; and electrical circuits.

The Energy Fair is part of DP&L's and Vectren's School Education Program facilitated by OEP throughout the school year. The school program is part of DP&L's ongoing energy efficiency efforts for customers, which also include rebates on new heat pumps and air conditioners, discounts on energy-efficient lighting, free refrigerator recycling and rebates for business customers.
