Sound, Heat, Light and Electricity Transformation From your previous lesson, you have learned that there are forces that affect the movements of different objects. In this lesson, you will understand that forms of energy like sound, heat, light, and electricity can be transformed. You will be able to demonstrate these energy transformations. Like gravity and friction, sound, heat, light, and electricity are other forms of energy that may be explained in terms of movement of smaller objects. Quarter 3 - Week 4 Sound is a form of energy produced by hilling two objects together or by vibrating objects, like strings of guitar. When you speak, sing or hum, your vocal cords vibrate. Without any medium, sound cannot travel. Heat or thermal energy is the energy from the moving molecules or tiny particles in matter. It is transferred from bodies of higher temperatures to bodies of lower temperature. Light is an energy that is transported and produced by vibrations of exceedingly small particles in matter through electromagnetic (EM) waves. The sun's energy travels as a visible light, the only EM wave that can be seen by the naked eyes. Electricity is an energy when electrons move from one atom to another. Atoms are basic building blocks of matter that make up everything. Electrons are small particles that spin around the center of the atom holding a negative (-) charge while protons are particles in the center of an atom that hold a positive (+) charge. Sound energy from vibrations of guitar strings ELECTRICITY Light and heat energy from Sun Electricity runs these appliances (electric fan, television, and radio) Learning Task: Perform the activity. Using these electrical appliances, tell what forms of energy is/are produced when using electricity. Write your answers on a one whole sheet of paper. 1. 2. 345 6. 7. mmga Heat energy produced by burning woods 8. 9. 10.​
