Build wave intuition from one oscillator outward
Start on the topic route, keep the Waves Evidence Loop compact, and reuse the authored wave order before widening into the rest of the branch.
The topic route gives the branch a map, the guided collection keeps the story compact, the waves starter track preserves the authored order through sound, pitch-versus-loudness cues, beats, the Doppler shift, and air-column resonance, and the interference revisit gives one clean place to test whether the wave picture still feels concrete.
Primary move
Open topic route
No saved progress yet inside Oscillations and Waves.
Entry diagnostic
Start from the opening step
No saved diagnostic checks are available yet, so the opening step is still the best entry into the collection.
Reuses the guided collection entry for Waves Evidence Loop, with 0 of 2 probes already ready.
- 1Topic routeNot started
Frame the branch on the oscillations and waves topic page
Use the topic route first so the oscillator, traveling-wave, and standing-pattern story is visible before the path narrows.
No saved progress yet inside Oscillations and Waves.
- 2Guided collectionNot started
Keep the path compact with Waves Evidence Loop
Reuse the existing guided collection when the wave story should stay teacher-friendly and bounded.
Orient with the oscillations and waves topic route is the next guided collection step.
- 3Starter trackNot started
Run the authored waves starter track
Keep simple harmonic motion, wavelength, longitudinal sound, pitch-versus-loudness reasoning, beats, the Doppler shift, interference, standing waves, and air-column resonance in the same authored order used elsewhere in the catalog.
Simple Harmonic Motion opens this track and sets up the rest of the path.
- 4ConceptNot started
Return to wave interference for one focused checkpoint
Reopen the interference concept when you want one concrete place to test whether the wavelength and timing story still holds.
