Teachers' Domain, Assessing Understanding, published June 19, 2009, retrieved on ,http://www.teachersdomain.org/resource/tdpd.sci.hpssc2/ Assessing Understanding is a graduate-level professional development course. It is designed to enhance your understanding of inquiry-based approaches to teaching standards-based physical science at the high school level.

In this lesson, students use a variety of resources to explore the concepts of potential, kinetic, and total energy within different types of systems. Students watch a video that explains the transfer of energy in a trebuchet's release, use an interactive activity to determine the types of energy involved in different parts of a roller coaster ride, do an in-class investigation that demonstrates the effect of mass and gravity on energy systems, explore the difference between gravitational and elastic potential energy, and finally, use the formulas for kinetic and potential energy to examine the path of a projectile.
