"During the school year, we have projects, labs and other activities that revolve around biodiesel and ethanol, and now the students can showcase what they've learned," said Erin Gawron, science department co-chair at Heritage.
Students learned how to create biodiesel using the used fryer grease from the cafeteria and ethanol using old fruit from a grocery store or the school cafeteria.
"Biodiesel is easy to make at home, and it's easy for students to make batches of it in class," Gawron said. "It's fun to do this project because it's a real way for student to apply the knowledge they have gained in class. They are actually doing it in the lab and making it the way professionals do."
The expo features display boards with information, newsletters, brochures and hand outs. A biodiesel reactor, ethanol still, flex fuel vehicle and hybrid car also will be on display.
"It's a good way for people to learn more about being green, some easy ways to do it and some easy things that can be done when the price of gas goes up," Gawron said.
Heritage High School is located at 2400 Granade Road.
