Holt Physics 1 Chapter 17 Lesson Plan MOTIVATE (5 minutes) __ Demonstration, Potential Energy, TE This demonstration uses a lump of clay to help students understand the relationship between an electric field and electrical potential energy. (BASIC) TEACH (25 minutes) __ PowerPoint® Resources Use the customizable presentation to help students master the concepts in this section. (GENERAL) __ Transparency Master 58A, Charge Moved in a Uniform Electric Field This transparency master shows how a charge moves from one point to another in an electric field, and the potential energy changes that result. __ Visual Strategy, Figure 4, TE Students explain how they would modify the figure to make the case similar to that of gravitational potential. (GENERAL) __ Sample Set A, Potential Energy and Potential Difference, SE This sample and practice problem set covers potential energy and potential difference. (BASIC) __ Classroom Practice, Potential Energy and Potential Difference, TE Use this problem as a teamwork exercise or for demonstration at the board or on an overhead projector. (BASIC) __ Quick Lab, A Voltaic Pile, SE Students use coins and pieces of wet paper towels to make a stack with a small voltage difference.
