Understanding ideas about energy can help to explain many events that occur in the natural and worlds. Energy exists in different forms including light, heat, chemical, and motion. All different forms of energy can be grouped into two categories: potential and kinetic. Kinetic energy is associated with motion. Potential energy exists in three forms: gravitational, elastic, and chemical. Gravitational potential energy is associated with the relative positions of objects. energy. 2. Explain the basis for grouping various forms of energy into potential and kinetic categories. 3. Discuss the different types of potential energy. potential and kinetic energy.

Meteorologists Clean Memphis City of Memphis Memphis International Airport Water on Wheels (University of Memphis) Standard 10 Energy – 1.5 weeks GLE 0607.10.2 Analyze various types of energy transformations. Scaffolded (Unpacked) ideas Objects can have elastic potential energy due to their compression, or chemical potential energy due to the arrangement of their atoms. Objects can gain potential or lose potential energy. When an object falls, a spring is released, or a substance changed chemically, its potential energy decreases and its kinetic energy increases. Energy can be transferred from one place or object to another. GLE 0607.Inq.1 Design and conduct open-ended scientific investigations. GLE 0607.Inq.3 Synthesize information to determine cause and effect relationships between evidence and explanations. GLE 0607.T/E.1 Explore how technology responds to social, political, and economic needs. Essential questions: 1. Describe the fundamental principles of energy transformation. Recognize that energy can be transferred from one type to another. Relate transformations between kinetic and potential energy in systems to the law of conservation of energy. Write an explanation detailing how energy is transformed in a common object. Identify different sources and forms of energy.
