3rd Quarter Science Intervention - Forms of Energy

Sound Energy

A sound is a form of energy produced by hitting two objects together or by

vibrating objects, like strings of the guitar. When you speak, sing, or hum, your

vocal cords vibrate. Without any medium, sound cannot travel.

Heat or Thermal Energy

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 Energy

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.

Electrical Energy

Electricity is energy when electrons move from one atom to another.

Atoms are basic building blocks of matter that makeup 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 holds a

positive (+) charge.

Law of Conservation of Energy

The Law of Conservation of Energy states that energy is neither created nor destroyed but only changes forms (transforms). All of the energy that goes into a system is constant. In other words, energy may be converted from one form to another, but it does not disappear or multiply.
