S3.8.2 For the adult
Energy transfers
When a candle burns, where does its energy go?
What this chapter teaches
Energy transfers move energy between stores by a force, by heating, by light or sound, or by an electric current. A transfer diagram shows stores as boxes and the way on each arrow.
Three questions to ask
There is no one right wording. Listen for the idea.
- What stores are in a ball held high, and then just before it lands?
- What does the arrow in a transfer diagram stand for?
- When a candle burns, where does its energy go?
After the chapter, the learner can
- Describe how energy moves when a candle burns or a ball falls
- Draw an energy transfer diagram
What they copy into their notebook
Energy moves from one store to another. A falling ball moves energy from the gravitational store to the kinetic store, by a force. The total stays the same.
