A. Waves involve a transfer of energy without a transfer of matter.
B. Water and sound waves transfer energy through a material.
C. Light waves can travel through a vacuum and through matter.
D. The Law of Conservation of Energy: Energy is conserved as it transfers from one object to another and from one form to another.
TEST ITEM SPECIFICATIONS
This benchmark may be assessed using:
- Clarification :
Students will identify and/or describe the transformation of energy from one form to another.
Students will differentiate between potential and kinetic energy.
Students will identify and/or explain situations where energy is transformed between kinetic energy and potential energy.
Students will identify and/or describe examples of the Law of Conservation of Energy.
- Content Limits :
Items will not assess transformations involving nuclear energy.
Items may address a maximum of five energy transformations.
Items will not require calculations.
Items assessing energy transformations will not be placed in a life science context.
- Stimulus Attributes :
- Response Attributes :
- Prior Knowledge :
Items may require the student to apply science knowledge described in the NGSSS from lower grades. This benchmark requires prerequisite knowledge from SC.3.P.11.2 and SC.5.P.10.4.
SC.6.P.11.1 Explore the Law of Conservation of Energy by differentiating between potential and kinetic energy. Identify situations where kinetic energy is transformed into potential energy and vice versa.
SC.7.P.11.3 Cite evidence to explain that energy cannot be created nor destroyed, only changed from one form to another.
