Energy is the ability to do work. Energy can be thought of as a currency which is universally accepted as the way to make things happen. Energy can be stored in many ways and transferred from place to place in many ways.
Some of the most frequently recognized types of energy are heat and light. These, along with others, can be classified as a phenomenon known as electromagnetic radiation (EM). Radiation is energy that travels and spreads out as it goes. The visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.
Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
