How energy travels around
Observe and provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents
Quick check
Can the learner 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?
Ask this to see whether the topic is secure.

The approach
For ages 9\u201310: gather first-hand evidence that energy travels from a source to a destination by four observable means \u2014 sound, light, heat, and electric current. Throughout, name the source and destination explicitly, press for evidence that energy arrived (the bulb lit, the ear heard, the thermometer rose), and frame sound/light/heat/current as the MEANS by which energy is shifted rather than as 'stuff' a device makes from nothing. Stay strictly qualitative \u2014 no measuring or numbers for energy. The electric-current case depends on prior knowledge of a simple series circuit.
Common misconceptions
- Thinking a device 'makes' light/sound/heat from nothing rather than transferring energy that arrived from a source (the bulb 'contains' light) — misses source→destination.
- Treating light, sound, heat and electric current as kinds of 'stuff' rather than means of transferring energy (the seed of the later store-vs-pathway error).
- Believing energy is 'used up' on the way rather than transferred to the destination and surroundings.
- Thinking electric current is 'used up' in the bulb (current consumed) rather than energy being delivered by the current as it passes — a common circuit companion error.
- Assuming transfer needs touching in every case — not recognising light and radiated heat cross a gap (links to non-contact ideas in Forces).
- Confusing the energy with the source object or the wire itself.
Useful representations
- Four paired source→destination scenes, one per transfer means (buzzer→ear, lamp/Sun→surface, hot object→cool object, battery→bulb)
- A 'travelling energy' arrow/pulse running along each pathway from source to destination
- A simple series circuit as the canonical electric-current transfer (battery → wires → bulb)
- An evidence-of-arrival cue for each case (lit bulb, sounding ear, rising thermometer)
Teaching practices
- Give first-hand observation of each of the four transfers — feel the warmth from a hot object, hear the buzzer, trace the wire from battery to bulb, feel the Sun's light warm a surface — so the transfer is evidenced, not just asserted.
- For every example name the SOURCE and the DESTINATION explicitly ('energy starts at the battery, ends at the bulb') — source→pathway→destination is the throughline that unifies all four cases.
- Press for evidence that energy arrived: 'how do you know?' → the bulb lit, the ear heard, the thermometer rose — building the NGSS 'observations as evidence' practice.
- Frame sound, light, heat and electric current as the MEANS by which energy is shifted, not as 'stuff' the device makes from nothing — the bulb provides a pathway for the battery's energy to leave as light (forward-compatible with the KS3 stores/pathways model).
- Lean on the prerequisite circuit knowledge for the electric-current case: a complete loop lets energy reach the bulb; a break stops it.
- Keep it strictly qualitative — no measuring or numbers for energy (respects the assessment boundary and the age).
Activities to try
- 1
Observe four transfers: source \u2192 pathway \u2192 destination
Why it works: The same story \u2014 energy starts here, travels by some means, arrives there \u2014 holds across all four cases; energy is transferred from a source to a destination through a pathway, and you can evidence that it arrived.
- Set up or observe each of four transfers and, for each, say out loud where the energy STARTS (source) and where it ENDS UP (destination): a buzzer/drum sends energy as sound to your ear; a lamp or the Sun sends energy as light across a gap to a surface; a hot object (e.g. a hot pan) warms a cooler one (e.g. a cold spoon) by contact; a battery sends energy along wires to a bulb.
- For every case, answer 'How do you know the energy got there?' with the observed evidence \u2014 the bulb lit, the ear heard, the surface was lit up or warmed, the thermometer/spoon rose in temperature.
- Before running each case, trace or draw an arrow from source to destination predicting the path the energy will take, then check it.
- State for each case that energy moved from where it started to where it ended up, using the same 'source \u2192 pathway \u2192 destination' wording every time.

Make and break the electric pathway
Why it works: A complete circuit provides a pathway for energy to travel from the battery to the bulb; the bulb shines only because energy reached it, not because it 'contains' light.
- Join a battery to a bulb with wires to complete a loop and observe the bulb light; then break the loop and observe the bulb go out.
- Say what the complete loop allows ('energy can reach the bulb') and what the break stops ('energy can't get there').
- Describe the chain: the battery gives energy to the current, the current carries energy along the wires to the bulb, where it is transferred to light and heat (an old-style filament bulb gives off much more heat than light).
- Optionally, trace the energy arrow from battery to bulb before completing the circuit, then run it to check.

Reference panels and consolidation check
Why it works: Consolidates the four cases and the source/destination language, and distinguishes the transfer means from each other and from the source object.
- Use a labelled reference scene for each of the four transfers (source, pathway arrow, destination) and reveal 'how do you know it got there?' \u2014 the bulb lit / the ear heard / the thermometer rose.
- Match each everyday example to its transfer means (sound, light, heat, electric current) and sort mixed scenarios by which means is at work.
- Identify the evidence of arrival for a given scenario, and put a scenario in order: source \u2192 pathway \u2192 destination.
- Trace a two-step example: a solar panel makes a fan spin \u2014 say where the energy came from and how many transfer means it used (light from the Sun, then electric current to the motor).
