Science Waves, Light & Soundusually ages 12–13

The Electromagnetic Spectrum

Describe the full electromagnetic spectrum from radio waves to gamma rays, in order of increasing frequency and energy; explain that all EM waves travel at the same speed in a vacuum; and describe the uses and hazards of different regions

How to tell they’ve got it

Tick these off as you see them — no test required.

Lists the seven regions of the EM spectrum in order of increasing frequency
States that all EM waves travel at 3 × 10⁸ m/s in a vacuum
Gives at least one use and one hazard for each region of the spectrum
Explains why some EM waves are more dangerous to living tissue than others (linked to frequency/energy)

Try this together

If your child heard about microwaves, X-rays, and visible light all being part of the same family, could they explain what makes them different from each other and name one useful application and one risk for each?

Builds on

Wave Properties & Typesages 11–12The electromagnetic spectrum is understood as a family of transverse waves — requires the general wave properties framework

Observing with Light Wavesages 11–13EM spectrum as astronomy tool depends on knowing the full EM spectrum from radio to gamma

Reflection & Refractionages 11–12Reflection and refraction of light provides entry-point experience with one member of the EM spectrum

Curriculum alignment

Candidate matches to official curriculum codes — machine-suggested, unreviewed (v0.1).

This skill sits beyond Year 6 in the Australian Curriculum, so no F–6 code is matched. It also sits beyond the NSW K–6 syllabuses. It also sits beyond Level 6 in the Victorian Curriculum.
