能量类型的命名
Naming types of energy
掌握并运用描述能量类型和能量转移的词汇——动能、势能、热能、光能、声能、电能、化学能、储存的能量、能量转移、能量转化——并用这些词语描述熟悉情境中的能量变化
Name and use vocabulary for types of energy and energy transfer — kinetic energy, potential energy, heat energy, light energy, sound energy, electrical energy, chemical energy, stored energy, energy transfer, energy transformation — and describe energy changes in familiar situations using these terms
学习证据 / Evidence
- 说出电池中储存的能量、拉伸的弹簧和运动中的小球分别具有什么类型的能量
- 使用“能量转移”或“能量转化”来描述手电筒或烤面包机等简单装置中发生的能量变化
- 区分“储存的能量”和“转移的能量”，并为每种各举一个正确的例子
- Name the type of energy stored in a battery, a stretched spring, and a moving ball
- Use 'energy transfer' or 'energy transformation' to describe what happens in a simple device such as a torch or a toaster
- Distinguish between 'stored energy' and 'transferred energy' with a correct example of each
评估问题 / Assessment
