Waves Evidence Loop

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

About this guided path

Open the authored rationale, highlights, and educator framing only when you need more context than the next step.

The topic page 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 filtered challenges keep 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.

Guided path

Follow the next steps in one authored order.

Each step still opens an existing topic page, concept bench, track, or challenge. This page only keeps the authored order legible.

4 steps across 9 concepts, with one clear first move.

Next stepTopic page

Orient with the waves topic page

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

  1. 1Topic pageNot startedNext step

    Orient with the waves topic page

    Use the topic landing page to frame wavelength, Doppler shifts, interference, and standing patterns before the deeper ordered work starts.

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

  2. 2Starter trackNot started

    Run the full waves starter track

    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.

    Simple Harmonic Motion is the next best step inside Waves.

    Ask learners to deliberately land on a destructive-interference band after the wavelength story is already in place.

Check your starting point

Open the diagnostic only when you need help deciding whether to continue, restart, or skip ahead inside this path.

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 page or jump straight to extension practice.

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.

Path tools

Share or assign this path

Copy a stable collection link or save a compact bundle only when you need to relaunch or share the sequence elsewhere.

Share this collection

Copy a stable collection link. Links stay public and never include saved progress or private account state.

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 waves topic page. Assignment completion is derived from the same concept, starter-track, and challenge facts already used elsewhere in the product.
