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

Energy Transformations ENERGY IN = ENERGY OUT 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. © KeslerScience.com

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

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

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

Energy Transformations Can you follow the energy flow? Mechanical energy KE (wind) (turning blades) (pump) Before showing the answers: Have students get with a partner to list all the energy flows they can figure out form the diagram. Class discussion may lead to other transformations. Also, have students draw or name an object that they think demonstrates mechanical energy. Then ask them to work with another student to list any transformations they think might happen. © KeslerScience.com

Thermal Energy - KE Energy Transformations 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 © KeslerScience.com

Energy Transformations Can you follow the energy flow? Chemical energy PE (wax as fuel) Thermal KE (burning wick) Radiant energy KE (light) Before showing the answers: Have students get with a partner to list all the energy flows they can figure out form the diagram. Class discussion may lead to other transformations. Also, have students draw or name an object that they think demonstrates mechanical energy. Then ask them to work with another student to list any transformations they think might happen. © KeslerScience.com

Energy Transformation Energy Transformation INB Template 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”. © KeslerScience.com

Energy Transformation Energy Transformation INB Template 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. These can also be used as review for assessments by adding new objects to the list. © KeslerScience.com
