能量如何传递

观察并提供证据，说明能量可以通过声音、光、热和电流从一个地方传递到另一个地方

Observe and provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents

学习证据 / Evidence

• 分别举出至少一个声音、光、热和电流传递能量的例子
• 说明能量通过这些方式从源头传递到目的地
• 描述电流如何通过导线将能量从电池传递到灯泡

• Give at least one example of energy transfer by each: sound, light, heat, electric current
• Explain that energy moves from a source to a destination through these means
• Describe how electric currents transfer energy from a battery to a bulb through wires

评估问题 / Assessment

{{name}}能举出能量传递的例子吗——比如暖气片发出的热量让房间变暖、灯光传到你的眼睛、或者电流流过导线？

Can {{name}} give examples of how energy moves around — like heat from a radiator warming a room, light from a lamp reaching your eyes, or electricity flowing through a wire?
