Energy from the sun: the Lantern
Where the sun's energy comes from, and how a Lantern runs without the grid.
Planned. This module is part of the plan and is not written yet.
Why it matters
The Lantern has no grid connection at all. Every light, fan and computer in it runs on sunlight caught by its own panels and stored in its own battery.

Inside the module.
4 lessons in order, about 45 minutes in all, then a short test. Learners go at their own pace; the minutes are a guide, not a timetable.

Lesson 1: Energy from the sun
Sunlight carries energy that warms the ground and grows our crops.
Explain10 min, from minute 0
Lesson 2: Panels turn light into electricity
A solar panel turns some of the light that hits it into electricity.
Explain10 min, from minute 10
Lesson 3: A day in the Lantern's power
Follow the Lantern's energy from morning sun, to battery, to evening lessons.
Investigate15 min, from minute 20
Lesson 4: Check your skills
Questions on where the Lantern's power comes from.

End-of-module test
Explain that sunlight carries energy that panels turn into electricity, and describe how a Lantern runs on its own panels and battery without the grid.
Mastered at 85% or more. Retake it until you pass; nothing is lost, and each try gives feedback.
Already know it? A Challenge Test (planned) clears the whole module: 90% overall, no objective below 75%.

Needs first
This module has no prerequisites of its own. Like every first step, it assumes the Digital skills gateway: the first module on using a computer, which a Challenge Test clears in minutes.

Every route on this map starts in a classroom with 24 stations, a tutor that works offline and a facilitator upstairs. Four are planned and waiting for light.
