Waves Evidence Loop

Not started

Use one topic route, one starter track, and one focused challenge so the wave story stays bounded for a teacher-led lesson block.

This set is for the moment when learners need the oscillator-to-wave sequence to stay compact. It starts with the existing topic route for orientation, uses the authored waves starter track for the main order, then closes with challenge surfaces that are already part of the current concept pages.

The topic route frames the branch first, the starter track preserves the authored order from oscillation through sound, pitch-versus-loudness cues, beats, and the Doppler shift into standing-pattern and air-column-resonance ideas, the interference challenge forces one concrete target, and the filtered challenge hub keeps extension work inside the same wave path.

Educator note

Best for a short lab block where everyone should share one sequence before branching into extension practice.

Entry diagnostic

Decide where to enter this path without opening a second testing system.

Reuse the SHM quick test and the dark-band challenge to see whether the compact wave lesson should begin at the topic route or jump straight to extension practice.

Check whether this lesson set should start at orientation or extension

Start from the opening step

No saved diagnostic checks are available yet, so the opening step is still the best entry into the collection.

Uses the same local-first concept, challenge, and track facts already saved in this browser.

Shareable concept bundle

Package a compact launch path from this guided collection.

Keep the bundle lightweight: choose the collection entry points that matter, give the package a clear summary, and share one stable link back into the same topic, concept, track, and challenge surfaces that already exist.

Bundle progress below stays local-first and never rides along with the shared link.

Included entry points

Uncheck anything that should stay outside this shareable bundle.

Assignment mode

Save the current bundle selection as a stable assignment link.

This stays intentionally small. The assignment stores the selected guided-collection steps and an optional note, then learners reopen the same concept, track, topic, and challenge surfaces through one stable entry point.

Sign in to save a stable assignment link. Signed-out bundle sharing above still stays public.

Launch starts on Orient with the oscillations and waves topic route. Assignment completion is derived from the same concept, starter-track, and challenge facts already used elsewhere in the product.

Bundle launch order

Keep the selected bundle steps explicit.

Launch starts on Orient with the oscillations and waves topic route
  1. 1Orient with the oscillations and waves topic routeTopic routeUse the topic landing page to frame how oscillator, traveling-wave, and standing-pattern ideas fit together before the deeper ordered work starts.
  2. 2Run the full waves starter trackStarter trackKeep simple harmonic motion, wave speed, longitudinal sound, pitch-versus-loudness cues, beats, the Doppler shift, interference, standing waves, and air-column resonance in the existing authored order.
  3. 3Close with the dark-band interference challengeChallengeAsk learners to deliberately land on a destructive-interference band after the wavelength story is already in place.
  4. 4Keep extension work on the filtered challenge hubChallenge hubWhen some learners need another task and others need review, open the existing challenge browser already filtered to the waves path.

Ordered steps

Reuse the current surfaces in one bounded sequence.

Every step still lands in an existing topic page, concept page, starter track, or challenge flow. The collection only keeps that order explicit.

1 starter track references stay inside the current track system.

    Orient with the oscillations and waves topic route

    Use the topic landing page to frame how oscillator, traveling-wave, and standing-pattern ideas fit together before the deeper ordered work starts.

    Give the lesson one shared map before learners branch into the authored sequence.

    Open this topic route before the linked concepts start accumulating saved progress.

    Keep simple harmonic motion, wave speed, longitudinal sound, pitch-versus-loudness cues, beats, the Doppler shift, interference, standing waves, and air-column resonance in the existing authored order.

    Reuse the canonical track instead of rebuilding a separate lesson shell.

    Simple Harmonic Motion opens this track and sets up the rest of the path.
