Learning Objectives

Indicator: 1.2.3.LI.1 - Identify instruments used for measuring electrical and non-electrical quantities in renewable energy systems.

By the end of the lesson, learners can:

Distinguish between electrical quantities (voltage, current, power, resistance, energy) and non-electrical quantities (temperature, irradiance, wind speed, fluid flow) found in renewable energy systems.
Identify at least five instruments used to measure electrical quantities and explain what each measures.
Identify at least five instruments used to measure non-electrical quantities and explain what each measures.
Match each measurement instrument to the specific renewable energy application it serves (solar, wind, hydro, or biomass systems).
Justify the choice of a particular instrument for measuring a given quantity in a renewable energy system during class discussion.

Exemplars (from the NaCCA curriculum)

Managing Talk for Learning: In a moderated discussion, learners discuss electrical and non-electrical parameters in renewable energy systems that require measurement and indicate the instrument that could be used.
Initiating Talk for Learning: The facilitator presents a comprehensive list of electrical and non-electrical quantities in energy systems that require measurement and the associated instruments for measurement.
Experiential Learning: Learners inspect the various instruments for the measurements.
