Learning Objectives

Indicator: 1.3.1.LI.1 - Describe the generation of electricity from solar cells/panels.

By the end of the lesson, learners can:

Explain in their own words how sunlight is converted into electricity by a solar panel.
Identify the main components of a solar panel system (solar cells, inverter, battery, charge controller) and state the role of each.
Describe at least two advantages and two disadvantages of solar energy for life and the environment.
Discuss the relationship between solar energy and the environment, including its benefits and potential concerns.
Present a group explanation of solar electricity generation using a diagram or concept map.

Exemplars (from the NaCCA curriculum)

Use a Talk for Learning approach to engage learners to revise various forms of electricity generation from the JHS curriculum (B7.4.2.1.1) and do group presentations.
- Guide learners to use diamond nine strategy 3 to brainstorm on the meaning, advantages, and disadvantages of solar energy to life and the environment.
- Learners use concept maps/videos/pictures/charts/diagrams, and internet resources to describe electricity generation from solar panels to create awareness of the relationship between solar energy and the environment.
Teaching and Learning Resources:
- Prototypes of solar panels
- Charts, pictures, and simulations of various forms of electricity generation.
- Internet resources such as (https://www.youtube.com/watch?v=9BgDt407uQc; https://www.youtube.com/watch?v=lxoHqV2fMK4)
- Different appropriate materials from the environment.
