Lesson notes

Learning Objectives

Indicator: 1.2.2.LI.3 - Explain how electricity is generated from water, wind, solar, biomass, and biogas energy sources.

By the end of the lesson, learners can:

Recall the five renewable energy sources listed in the indicator and identify the key component each requires to generate electricity (water flow, wind speed, sunlight, organic matter, and organic waste).
Describe, in the correct order, the step-by-step process by which water is converted into electrical energy in a hydroelectric power plant.
Explain, using simple diagrams, how wind turbines and solar photovoltaic panels convert their respective natural inputs into electrical energy.
Distinguish between biomass and biogas as energy sources, and outline the electricity generation process for each.
Present a group research finding on one renewable electricity generation process to the whole class, using accurate technical vocabulary.

Exemplars (from the NaCCA curriculum)

Initiating Talk for Learning: Through questions and answers and watching videos from YouTube, learners share their views on processes for generating electricity from water, wind, solar, biomass, and biogas energy sources.
Project-based Learning: Learners work in different task groups to research how power is generated from various sources. Groups share their findings with the whole class. Mixed ability/gender groups are given a company each to research that manufactures electricity generation systems for renewable energy sources. Groups share their findings with the whole class.

Assessment (1.2.2.AS.3). The document marks these depth-of-knowledge levels for this indicator: Level 1 Recall; Level 3 Strategic reasoning.
