Energy Transformation Presented by Kesler Science

Essential Questions: How can you demonstrate energy transformations ? Ex: A flashlight battery changes chemical energy to electrical energy to light energy.

Energy Transformations Energy Transformation (Conversion) • The process of changing energy from one form to another • The flow from one type of energy to another © Kesler. Science. com

Energy Transformations Conservation of Energy • Energy can neither be destroyed nor created. • Energy doesn’t disappear. • Energy just transforms from one form into another. Ex: Electric energy converts to heat energy on a stove. © Kesler. Science. com ENERGY IN = ENERGY OUT

Energy Transformations Types of Energy Potential Energy Kinetic Energy that is stored Energy that is in motion Forms of Potential Energy Mechanical Chemical Nuclear Electrical Forms of Kinetic Energy Mechanical Radiant Electrical Thermal Sound © Kesler. Science. com

Energy Transformations ENERGY Electrical Chemical Mechanical (gravity) Potential K Kinetic Electrical Mechanical (elastic) Nuclear © Kesler. Science. com Radiant Sound Thermal Mechanical (wind)

Energy Transformations Mechanical Energy - KE Mechanical Energy - PE The energy a body possesses because of its motion caused by gravity or elasticity The energy a body possesses because of its position Energy stored by gravity or elastic potential Ex: Flowing water Winds Arrow shot from a bow Bouncing on a trampoline Ex: Book on a table Compressed spring Rubber band pulled back © Kesler. Science. com

Energy Transformations Can you follow the energy flow? • Mechanical energy KE (wind) • Mechanical energy KE (turning blades) • Mechanical energy KE (pump) © Kesler. Science. com

Energy Transformations Thermal Energy - KE • Also referred to as heat energy • The total energy of atoms and molecules that are constantly in motion. Ex: Burner of a stovetop turned on Hot cup of cocoa Fire © Kesler. Science. com

Energy Transformations Can you follow the energy flow? • Chemical energy PE (wax as fuel) • Thermal KE (burning wick) • Radiant energy KE (light) © Kesler. Science. com

Energy Transformations Radiant Energy – KE • Also referred to as solar or light energy • Energy caused by the movement of electromagnetic waves Ex: Light emitted by lightbulbs Sun Microwaves © Kesler. Science. com

Energy Transformations Can you follow the energy flow? • Radiant energy KE (sun) • Chemical PE (photosynthesis) • Chemical PE (food) © Kesler. Science. com

Energy Transformations Sound Energy - KE • Energy in the form wave motion • Vibrations spread in all directions as one vibrating object touches another causing it to vibrate • Ex: Drum Tuning fork Talking © Kesler. Science. com

Energy Transformations Can you follow the energy flow? • Solar energy PE (sun) • Electrical energy PE (solar panel) • Electrical energy KE (wires) • Sound energy KE (music) © Kesler. Science. com

Energy Transformations Electrical Energy - KE Electrical Energy - PE Moving electrons from one point to another in a conductor Stored electrons not moving Ex: Electric current in wires Lightning © Kesler. Science. com Ex: Light bulb turned off Stove turned off Power outages Electrons in clouds

Energy Transformations Can you follow the energy flow? • Electric energy KE (lightning) • Thermal KE (fire) © Kesler. Science. com

Energy Transformations Chemical Energy - PE Energy stored in chemical substances. Ex: Fuel Explosives Food Batteries Wood © Kesler. Science. com

Energy Transformations Can you follow the energy flow? • Chemical PE (battery) • Electrical energy KE (electricity) • Radiant energy KE (light) © Kesler. Science. com

Energy Transformations Nuclear Energy - PE • Also known as atomic energy • The energy stored in the nucleus of an atom • Can be released by fusion (combining atoms nuclei) or fission (splitting atoms nuclei) Ex: Nuclear power plants (fission) the Sun (fusion) © Kesler. Science. com

Energy Transformations Can you follow the energy flow? • Nuclear energy PE (fusion) • Mechanical energy KE (turbine) • Electrical energy KE (generator/wires) © Kesler. Science. com

Energy Transformation INB Template 1. 2. 3. © Kesler. Science. com Cut out the Template You can easily cut out the “reveal windows” by folding the paper in half and cutting. Glue into INB using only a small dot of glue between each “reveal window”.

Energy Transformation INB Template 1. 2. 3. © Kesler. Science. com Cut out the Template along all solid lines. Place the Object/Energy strips in the pocket you just made. Cut out title and glue into INB or write your own title.

Energy Transformation INB Template 1. 2. 3. 4. © Kesler. Science. com Cut out the Template Fold along dotted lines to create a pocket. Glue into INB Use the pocket to store the object/energy type strips.
