b . Relate the transformations between kinetic and potential energy in a system (e.g., moving magnet induces electricity in a coil of wire, roller coaster, internal combustion engine). c. Gather data and calculate the gravitational potential energy and the kinetic energy of an object (e.g., pendulum, water flowing downhill, ball dropped from a height) and relate this to the conservation of energy of a system. d. Evaluate social, economic, and environmental issues related to the production and transmission of electrical energy. Objective 3: Describe common energy transformations and the effect on availability of energy. a. Describe the loss of useful energy in energy transformations. b. Investigate the transfer of heat energy by conduction, convection, and radiation. c. Describe the transformation of mechanical energy into electrical energy and the transmission of electrical energy. d. Research and report on the transformation of energy in electrical generation plants (e.g., chemical to heat to electricity, nuclear to heat to mechanical to electrical, gravitational to kinetic to mechanical to electrical), and include energy losses during each transformation.

How is energy determined and transferred? • What are the forms of energy? (i.e., gravitational, elastic, chemical, electrostatic, nuclear) How is energy conserved? • Is energy always conserved? • How are different ways energy is lost? What are some common energy transformations? • How does energy change form? How is heat transferred?

RL 4: Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9 – 10 texts and topics. RL 5: Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g., force, friction, reaction force, energy). RL 10: By the end of grade 10, read and comprehend science/technical texts in the grades 9 – 10 text complexity band independently and proficiently. WL 3: Write precise enough descriptions of the step-by-step procedures they use in their investigations or technical work that others can replicate them and (possibly) reach the same results. WL 7: Conduct short as well as more sustained research projects to answer a question (including a self generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of
