[HS.ETS.4.1] - Research and describe various ways that humans use energy and power systems to harness resources to accomplish tasks effectively and efficiently.
Clarification Statement: Examples of energy and power systems can include fluid systems such as hydraulics and pneumatics, thermal systems such as heating and cooling, and electrical systems such as electronic devices and residential wiring.
[WCA.9-10.7] -
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 the subject under investigation.
[HS.ETS.4.4] -
Calculate and describe the ability of a hydraulic system to multiply distance, multiply force, and effect directional change.
Clarification Statement: Emphasis is on the ratio of piston sizes (cross-sectional area) as represented in Pascal’s law.
