the Physics Education Technology Project
This set of 35 "clicker" questions (with answer key) was developed by a high school teacher specifically for use with the PhET Energy Skate Park simulation. It may be freely downloaded as a pdf file or as a Power Point document to enable teachers to sort and customize. Multiple screenshots and illustrations help students visualize changing kinetic/potential energy levels in a variety of situations. Student responses can be used to gauge understanding of conservation of energy.
Editor's Note: Middle school teachers may choose to skip Slides 20-35, as they pertain more to an introductory Physics course.

6-8: 4E/M2. Energy can be transferred from one system to another (or from a system to its environment) in different ways: 1) thermally, when a warmer object is in contact with a cooler one; 2) mechanically, when two objects push or pull on each other over a distance; 3) electrically, when an electrical source such as a battery or generator is connected in a complete circuit to an electrical device; or 4) by electromagnetic waves.
6-8: 4E/M4. Energy appears in different forms and can be transformed within a system. Motion energy is associated with the speed of an object. Thermal energy is associated with the temperature of an object. Gravitational energy is associated with the height of an object above a reference point. Elastic energy is associated with the stretching or compressing of an elastic object. Chemical energy is associated with the composition of a substance. Electrical energy is associated with an electric current in a circuit. Light energy is associated with the frequency of electromagnetic waves.
9-12: 4E/H1. Although the various forms of energy appear very different, each can be measured in a way that makes it possible to keep track of how much of one form is converted into another. Whenever the amount of energy in one place diminishes, the amount in other places or forms increases by the same amount.
9-12: 4E/H9. Many forms of energy can be considered to be either kinetic energy, which is the energy of motion, or potential energy, which depends on the separation between mutually attracting or repelling objects.
