![]() Electrical energy is described as an energy that is transferred by moving electrical charges through a complete circuit. Sound and light are introduced as forms of energy that are transferred by waves while heat is introduced as an energy that is transferred either by randomly moving particles, or by electromagnetic waves (radiation). In this grade level, the focus is on the sources of the different forms of energy and the different ways by which they are transferred from one place to another. All these forms belong to kinetic energy they are all associated with some kind of motion-the motion of waves, electrons, atoms, molecules, and objects. Among the many forms of energy, motion, heat, light, sound, and electrical energy are the most common and most familiar among students. At the end of the quarter, students should be able to realize that energy exists in different forms, energy transfers from one body to another, and that motion is the concrete manifestation that a body possesses energy. Overview The topics covered in Grade 7 deal with the relationship between motion and energy. ![]()
