能量储存与转移
Energy stores and transfers
识别主要的能量储存形式(动能、重力势能、弹性势能、热能、化学能、核能、电磁能)以及能量在不同储存形式之间转移的途径(机械方式、电的方式、加热、辐射)。
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)
学习证据 / Evidence
- 能说出并描述至少五种能量储存形式,并为每种举出一个现实世界中的例子。
- 能识别给定过程(如球下落、火柴燃烧)开始和结束时的能量储存形式。
- 能描述给定情境中两种能量储存形式之间的转移途径。
- 能追踪能量在系统中的流动,识别所涉及的所有能量储存形式和转移过程。
- 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
评估问题 / Assessment
如果{{name}}观看一个球被抛向空中后又落回地面,ta能否描述球在最高点和最低点时各具有什么类型的能量,并解释在这两个位置之间能量发生了什么变化?
If {{name}} 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?
