Connection to Maine Agencies

MEEP (Maine Energy Education Program) has an Apple Battery exploration and will come to interested schools, free of charge. Students experiment with making a battery by inserting different types of metals into an apple and measuring the electrical current they generate.

For schools in Aroostook County, a Maine Public Service (MPS) representative will come to interested schools, free of charge, to guide and support the concepts developed in this lesson.
