# How energy travels around

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

Subject: Science · Area: Energy · Ages 9 to 10
Page: https://lightmysky.com/learn/science/how-energy-travels-around-mt_X_aDUBh-HF

## Ready when they can

- 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

## Lesson: How energy travels around

Energy never stays in one spot. It moves from a source to somewhere else. Sound carries energy through the air to your ears. Light carries energy from something bright to your eyes. Heat carries energy from something warm to something cooler. Electric current carries energy through wires.

**Example.** A ringing bell makes the air vibrate. Those vibrations carry sound energy across the room, all the way to your ears.

*(drawing: Energy leaves the battery, travels through the wire, and reaches the bulb, lighting it up.)*

**Tip.** Every example has a source and a place the energy arrives. Sound: bell to ear. Light: lamp to eye. Heat: radiator to skin. Electric current: battery to bulb, through wires.

**Recap.** Energy always travels from a source to a destination, by sound, light, heat, or electric current through wires.
