Energy for Change

energy for changeGreen Energy Audit

by Jennie Liss Ohayon and Dan Johnston

Students and teachers can use parts or all of our step-by-step workbook to conduct an energy audit of their school. The whole module is designed to strengthen students’ understanding of concepts in physics such as power and energy by making real-world connections, and by using appropriate technology to inquire into their own environment (particularly the lighting systems of their school). They calculate potential energy savings from both behavioral (e.g., turning lights off) and operational (e.g., retrofits) measures. Finally, students synthesize their data and develop specific recommendations for administrators or the public.

Producing Biodiesel from Used Vegetable Oil

by Jennie Liss Ohayon, Mark Sterrett and Ryan Kuntz

In this lab, students learn how to think about what makes the energy in vegetable oil available to use for vehicle engines. They learn about the chemical reactions that produce biodiesel, and why these chemical reactions are needed to produce vehicle-ready fuel. They practice making biodiesel, and compare the results when they use different amounts of catalyst, and when they use either new or used vegetable oil.
