S3.8.8 For the adult
Fuels and energy resources
Will we ever run out of fuel?
What this chapter teaches
Renewable energy resources keep coming, such as sunlight, wind and flowing water. Coal, oil and gas are non-renewable. Burning fuels with carbon adds carbon dioxide to the air, which traps heat. Cooking fires waste much of their energy.
Three questions to ask
There is no one right wording. Listen for the idea.
- Which energy resources can be used again and again?
- What gas does a burning fuel add to the air?
- What are the good and bad points of cooking with wood, gas and sunlight?
After the chapter, the learner can
- Sort energy resources into renewable and non-renewable
- Explain how burning fuels adds carbon dioxide to the air
- Compare cooking with wood, gas and sunlight
What they copy into their notebook
Renewable: sunlight, wind, water, and wood if replanted. Non-renewable: coal, oil, gas. Burning fuels makes carbon dioxide, which traps heat. A solar cooker burns nothing.
