Simple rubric (ACARA-aligned for Years 8–10)

CriteriaExcellent (A)Satisfactory (C)Developing (E)
Scientific inquiry (ACSIS098) Designs clear questions, collects accurate sound data using Raven Lite, labels and exports metadata correctly, and justifies methods. Asks relevant questions, collects usable data, and demonstrates basic labelling and export skills. Attempts data collection but with inconsistent labelling or incomplete export; needs support to form questions.
Data analysis & interpretation Analyses spectrograms and waveforms to identify frequency, amplitude and patterns; maps to biology/ecology conclusions. Identifies main features in spectrograms; draws reasonable biological links. Finds some waveform features but misinterprets measurements or ecological implications.
Mathematical skills Calculates frequency from period, simplifies ratios, plots and interprets graphs with correct units. Performs basic calculations and plotting with minor errors. Requires stepwise support with calculations and graphing.
Ethics & citizen science Shows understanding of data reliability, species sensitivity, consent and metadata importance in citizen science. Recognises key ethical issues and the value of accurate data recording. Has limited awareness of ethical concerns and data reliability.
Communication Communicates findings clearly with labelled figures, concise conclusions and reflective insight. Presents findings clearly; figures may lack full labelling. Presentation is incomplete or unclear; needs help labelling graphs or explaining results.

Lesson 1 — The Science of Sound (TeachRock) paired with Raven Lite

Printable student worksheet — Lesson 1

Warm invitation: Close your eyes for a moment. Imagine you are in a garden at dawn — the air is cool, a soft chorus of birdsong wraps around you like a shawl. Today we will listen, record, and taste the timbre of bird voices.

  1. Question: What features of a bird sound will help you identify its species? List three things you will listen for.

    Answer: ______________________________________

  2. Using Raven Lite, record or open a short bird recording (10–30 seconds). Note: teacher will provide sample files if field recording is not possible.

    Filename used: ___________________ Location (if known): ___________________

  3. Observation: In one sentence describe the sound (e.g., short sharp notes, a warbling trill, rhythmic calls).

    Answer: ______________________________________

  4. Visual: Look at the waveform and spectrogram. Circle or note where amplitude is high (loud) and where it is low (quiet).

    Describe one visible feature you notice: ____________________________

  5. Biology link: Suggest what the sound might tell you about the bird (territory, mate, alarm, contact call). Explain briefly.

    Answer: ______________________________________

  6. Reflection on citizen science: Why is clear labelling (date, time, location, recorder name) important for scientific studies that use many recordings from volunteers?

    Answer: ______________________________________

Teacher-facing Raven Lite cheat sheet — Lesson 1 (step-by-step with annotated screenshot placeholders)

Tone note: guide learners gently, like presenting a favourite recipe — calm, descriptive, and encouraging.

  1. Open Raven Lite and create a new work folder for the class. [Screenshot 1: Raven Lite main window with menu visible]
  2. Import audio: File > Open. Select your WAV or AIFF file. If students record in the field, show how to drag-and-drop. [Screenshot 2: Open dialog highlighted]
  3. Adjust view: zoom horizontally and vertically so the waveform and spectrogram are clear. Use the zoom buttons or mouse scroll. [Screenshot 3: zoomed spectrogram area marked]
  4. Play and mark: use the play button to listen. Use the selection tool to highlight a 2–5 second example. [Screenshot 4: selection highlighted]

    Annotation: Encourage students to listen more than once; point out subtle details like note spacing and tone.

  5. Label selection: Use the annotation track (if available) to add a label like species or call type. Click Add to create a new label. [Screenshot 5: annotation dialog shown]
  6. Export metadata: File > Export selection as WAV (or Export selection time stamps) and save a CSV of labels if your version permits. Remind students to include date, time, location, observer.
  7. Measure amplitude peaks: Use the measurement tool to click on peaks in the waveform; note time stamps. [Screenshot 6: measurement tooltip shown]
  8. Save project and back up audio plus labels to shared drive or classroom folder for later analysis.

Quick teacher tips:

  • If your students cannot record outdoors, provide curated short bird clips (3–10 sec) labelled by species for lab use.
  • Show one example project live before letting students work.
  • Check metadata before students submit — teach them the habit of accurate, simple records.

  • Nice work asking the right question; that will make analysis easier.

Lesson 2 — The Mathematics Behind Sound paired with Raven Lite

Printable student worksheet — Lesson 2

Warm invitation: Settle at your workstation like you would prepare a small feast. Today we will look inside the sound — its shape, its spikes, its secret recipe of frequency and amplitude.

  1. Open a bird file in Raven Lite and display the spectrogram. Sketch or paste a screenshot of one clear call here (teacher may paste after printing):

    Sketch box: ____________________________

  2. Identify the highest amplitude region in the selection. Note time start and end.

    Start: ______ s End: ______ s

  3. Find the main frequency band in the spectrogram (notice brightest band). Estimate its frequency range (in Hz) using the frequency axis.

    Estimated range: _______ to _______ Hz

  4. Using Raven Lite tools or the cursor: record the peak frequency (Hz) of the loudest element.

    Peak frequency: _______ Hz

  5. Plot a simple bar or line showing amplitude (relative) vs time for the selected clip on the grid below. Label axes.

    Graph space: (use the back of the page)

  6. Explain how amplitude and frequency together help you tell two species apart.

    Answer: _______________________________________

Teacher-facing Raven Lite cheat sheet — Lesson 2

  1. Open Raven Lite and load sample clip. Show how to switch display to spectrogram if not visible. [Screenshot 1]
  2. Adjust spectrogram settings: set window size and colormap to show clear harmonic bands. For bird song, a medium window (256–1024) often works well. [Screenshot 2 with menu options]
  3. Use the cursor to read frequency at the brightest band. Record the value shown on the frequency axis or in the status bar. [Screenshot 3: cursor readout]
  4. To measure amplitude envelope, use the waveform view and selection tools to measure RMS or peak values if your Raven Lite build supports measurements. Otherwise, visually annotate relative amplitude. [Screenshot 4: waveform selection]
  5. Export frequency/time stamps: File > Export selection data (if available) or copy observed values into a CSV template for class analysis.
  6. Class extension: pool peak frequency values from groups, then compute mean and standard deviation (or range) to discuss variation within species.

Teacher praise and feedback examples — Lesson 2

  • I adore your careful reading of that spectrogram — such patience shows in your numbers.
  • Crystal clear peak identification — your frequency note is spot on.
  • Nice use of the zoom tool; the harmonic bands are much easier to see now.
  • Lovely plotting — your axes are labelled and your scale is sensible.
  • Excellent comparative thinking — you noticed how amplitude changes with call type.
  • Good method: averaging your group data gives a reliable class result.
  • Your export was tidy and well-organised; that makes later analysis delightful.
  • Great precision — your frequency measurement uses the right units (Hz).
  • Smart suggestion to try a few window sizes; that improves clarity.
  • Wonderful reflection on measurement error — you are thinking like a scientist.

Lesson 3 — Calculating Pitch paired with Raven Lite

Printable student worksheet — Lesson 3

Warm invitation: Imagine tuning a string instrument by ear — now we will tune our ears to the pulse inside a song and turn time into frequency.

  1. Open a bird call and zoom so you can clearly see repeating cycles or pulses.

    Time for one cycle (period) measured from spectrogram or waveform: T = ______ seconds

  2. Calculate the fundamental frequency using f = 1 / T. Show your working and units.

    f = ______ Hz (Working: 1 / ______ = ______)

  3. If you measured three different cycles and got periods 0.025 s, 0.026 s and 0.024 s, calculate the mean frequency. (Hint: compute each f then find the average.)

    Frequencies: _____ Hz, _____ Hz, _____ Hz Mean f = _____ Hz

  4. Biology link: Higher frequency calls can travel less far but may be better for close communication; lower frequencies travel farther. Give one example of why a species might evolve a high call and one example for a low call.

    High call reason: _____________________ Low call reason: _____________________

Teacher-facing Raven Lite cheat sheet — Lesson 3

  1. Find a clip with clear repeating pulses or a tonal element. [Screenshot 1: clear cycle marked]
  2. Use the cursor to mark the start and end of a single cycle and read the time stamps; compute period T = t_end - t_start. [Screenshot 2: time stamps highlighted]
  3. Explain and demonstrate the simple calculation f = 1/T. Have students compute aloud before writing results. [Screenshot 3: calculation shown in a text box]
  4. Provide a worksheet example where multiple cycles are averaged to show sampling reduces measurement error.

  • Terrific focus during measurement — that precision matters.

Lesson 4 — Musical Ratios paired with Raven Lite

Printable student worksheet — Lesson 4

Warm invitation: Think of a melody as a recipe of frequencies. Today we'll compare bird song intervals to musical intervals and taste the maths behind harmony.

  1. Choose two notes or tone elements in a bird song (A and B). Measure their peak frequencies: fA = ______ Hz fB = ______ Hz
  2. Compute the ratio fA : fB and simplify (e.g., 2:1, 3:2). Show working.

    Ratio simplified: ______

  3. Which musical interval does this ratio most closely match? (Examples: 2:1 = octave, 3:2 = perfect fifth, 4:3 = perfect fourth.)

    Closest interval: ______

  4. Describe whether the bird’s interval sounds consonant (pleasantly matching) or dissonant (clashing) to you. Explain briefly using your ratio.

    Answer: ______

  5. Ethics and aesthetics: discuss how studying birdsong with musical ideas can help connect art and science. One paragraph.

Teacher-facing Raven Lite cheat sheet — Lesson 4

  1. Identify two clear sustained elements in a recording. Use cursor to record their peak frequencies. [Screenshot 1: two peaks marked]
  2. Show students how to compute a ratio and simplify by dividing both frequencies by their greatest common divisor or by dividing one by the other to get a decimal and approximate a small-integer ratio. Example: 880 Hz / 440 Hz = 2 -> 2:1 octave.
  3. Provide a musical ratio cheat sheet: 2:1 octave, 3:2 fifth, 4:3 fourth, 5:4 major third, etc. [Screenshot 2: small table image placeholder]
  4. Class activity: groups compare bird ratios and vote on perceived consonance; discuss variation and whether natural signals align with human musical preferences.
  5. Wrap-up: discuss cultural bias — musical intervals are human constructs but comparison can deepen engagement.

Teacher praise and feedback examples — Lesson 4
