High School Science

STANDARD IV: Students will understand transfer and conservation of energy. Objective 1 : Determine kinetic and potential energy in a system. a. Identify various types of potential energy (i.e., gravitational, elastic, chemical, electrostatic, nuclear).

Explain observed phenomena in terms of conservation of energy

•

• Describe the energy of a closed system including transfer from potential to kinetic energy • Compare and contrast work and power and relate it to other forms of energy. • Identify types of potential energy • Calculate potential and kinetic energy

b. Calculate the kinetic energy of an object given the velocity and mass of the object. c. Describe the types of energy contributing to the total energy of a given system.

Objective 2: Describe conservation of energy in terms of systems. a . Describe a closed system in terms of its total energy. 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. Objective 3: Describe common energy transformations and the effect on availability of energy. a. Describe the loss of useful energy in energy transformations.

RL 1: Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions. RL 2: Determine the central ideas or conclusions of a text; trace the text’s explanation or depiction of a complex process, phenomenon, or concept; provide an accurate summary of the text. 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.
