Natural Sciences and Technology Grade 5 Term 3: Energy and Change Stored Energy in Fuels (PPT 2A)

Topic 1 Stored Energy in Fuels Fuels: forms of energy Gr 5 Natural Sciences and Technology – Term 3, Topic 1

What is energy? The ability to do work or cause change. produces warmth produces light produces sound produces movement produces growth powers technology Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Heat energy The sun gives off heat energy. When something gets hot it gives off heat energy. e.g. solar panels. Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Light energy This is the type of energy that something gives off when it glows or burns. e.g. torch. Light travels faster than sound. Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Energy that enables you to hear something Sound energy Energy that enables you to hear something Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Electrical energy This type of energy is made by an electric current, for example, electrical heaters, stoves and hair dryers. Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Kinetic or movement energy This is the energy that something has when it is moving, for example, kicking a ball, riding a bicycle. Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Potential or stored energy Energy that is stored in something. It is waiting to be used. Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Chemical energy Energy stored in fuels like coal and oil and in batteries and food. Chemical energy can also be called food energy or stored energy. Gr 5 Natural Sciences and Technology – Term 3, Topic 1

Gravitational potential energy Gravitational potential energy is the energy of something that could fall due to gravity. Gravity is the pull of the Earth, for example, a book on the edge of a table has the potential to fall to the ground if it is knocked. Gr 5 Natural Sciences and Technology – Term 3, Topic 1
