Heat Energy Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move the more energy they possess and the hotter they become. Thermal energy is also called heat energy. Chemical Energy Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas. Nuclear Energy Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity. Electrical Energy Electrical energy is the movement of electrons (the tiny particles that make up atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy. Radiant Energy Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays and radio waves. Light Energy Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye. Motion Energy Motion energy – or mechanical energy – is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind, a flowing river, a moving car, or a person running. Sound Energy Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate. Elastic Energy Elastic energy is a form of potential energy which is stored in an elastic object - such as a coiled spring or a stretched elastic band. Gravitational Energy Gravitational energy is a form of potential energy. It is energy associated with gravity or gravitational force – in other words, the energy held by an object. LIGHT ENERGY Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human eye. SOURCES OF ENERGY Sun Electric bulb Explosion Flame Led(light emitting diode) Fire Moon Tube light Uses of light energy It helps us to see things. It helps plants to make food and grow. It is used in power satellites and space stations. It is used in many electronic appliances. The energy of light from the sun can be harvested to solar panels and can be used for domestic use since it is eco-friendly and cost effective too. Strategies & Activities: Step: Teacher revises the previous topic. Step 2: Teacher introduces the new topic. Step3: Teacher explains the new topic. Step4: Teacher welcomes pupils’ questions. Step5: Teacher evaluates the pupils. Assessment & Evaluation: Mention the sources of light energy .2. Discusses the uses of light .3. Identify some objects that reflect light Use mirrors to form images. Assignment: List five sources of light energy. Mention three uses of light. uses mirror and shiny surfaces to reflect light List three things that reflect light.
