Energy stores and transfers
能量的储存与转移
Description
Identify the main energy stores (kinetic, gravitational potential, elastic potential, thermal, chemical, nuclear, electromagnetic) and the pathways by which energy is transferred between stores (mechanically, electrically, by heating, by radiation)
Mastery Evidence
- Names and describes at least five energy stores with a real-world example of each
- Identifies the energy stores at the start and end of a given process (e.g. a falling ball, a burning match)
- Describes the transfer pathway connecting two energy stores in a given scenario
- Traces energy through a system identifying all stores and transfers involved
Assessment Prompt
If your child watched a ball being thrown upward and then falling back down, could they describe what type of energy the ball has at the top of its arc and at the bottom — and explain what happened to the energy between those two points?
